June 5 is the ninth solar term for the lunar calendar. According to the "Monthly 72nd Settlement," the book says: "On the May Day, there is a valley of mangoes, which can be planted and harvested." This means that there is a rapid harvest of wheat, and there are mango rice varieties. The summer season has entered the summer, with abundant sunshine, long hours of illumination, and elevated temperatures. However, the amount of rainfall is not large, and it is suitable for the growth of most vegetable crops. The vegetables in the protected area of ​​spring clams are at a time of harvest and are also an important period for management. The melons, solanaceous vegetables and legumes planted in spring were harvested one after another, and the number of listed varieties increased, and the market supply was sufficient. The management and harvesting of spring leeks should be mainly done, and the preparation of vegetables for autumn wolfberry should be prepared.
Field management and harvesting of vegetables in protected areas
At this stage, greenhouses, greenhouses, tomatoes, cucumbers, eggplants and other vegetables are all harvested fruit to the harvest period, rapid plant growth, large transpiration, water and fertilizer needs, management is related to the quality of production and quality.
â—† Adjust the suitable growth environment
At present, it is a period of rapid growth and development of crops. First, it is necessary to regulate the suitable crop growth environment and promote the robust growth of plants.
The temperature regulates the temperature of the greenhouse suitable for crop growth according to different crop growth stages and weather conditions. Tomatoes and other thermophilic crops come out from the sun during the sunny day to 2 o'clock in the afternoon at 23 o C to 30 o C, from 2 pm to sunset at 26 o C to 23 o C, and at night at 15 o C to 18 o C; while cucumbers and other melon crops from sunset The temperature should be higher at 24 o'clock in the evening and more suitable at 20 o C to 18 o C. The leafy vegetables such as celery should be at 20 o C to 25 o C during the day and 10 o C to 12 o C at night. The cloudy daytime temperature should be reduced by 3°C-5°C. Special personnel should be arranged to take care of the adjustment of the temperature to avoid excessively high or low temperatures in the greenhouse. Sunny days at noon from 11 to 15 o'clock on the roof covering the shade net or spraying "Liliang" cooling materials to reduce the temperature inside the shed.
The humidity of the air is the same for the fruits and vegetables that belong to the thermophilic temperature. The air humidity requirements are also different. The peppers and cucumbers are more humid and the suitable humidity is 60%-90%. Especially the sweet peppers should be adopted in the sunny noon. Micro-spraying or spraying water between rows to increase the air humidity, if it is not conducive to plant growth and fruit development under high temperature and dry environment conditions, it is easy to induce virus disease infection; tomato, eggplant hi dry growth environment, suitable air humidity It is 45%-60%. It is possible to regulate the indoor air humidity through under-membrane irrigation, ventilation and humidity control, and indoor temperature adjustment to ensure the normal growth of crops and prevent the spread of diseases and insect pests.
Illumination at noon in summer is too strong and will adversely affect the crop, reduce yield and quality, and cause physiological diseases such as buds and sunburn. It should be covered in the roof from 11 to 15 o'clock on sunny days. 70% of shade nets.
â—† timely harvest
Harvesting too late not only affects fruit and plant growth but also reduces quality. Try to harvest in the early morning on a sunny day. The quality and taste of the product are better than those at other times.
â—† Timely plant consolidation promotes multiple results
The vines and vines of the cucumbers and tomatoes used for hanging vines must be arbitrarily cultivated and vines in a timely manner. When they grow to a height of about 2 meters, the vines or head-changing methods are used to extend the fruiting period. Cucumbers can be used to make plants grow neatly and conveniently, and labor is saved. At the same time, the tendrils are removed and the male flowers are removed.
Remove the old leaves, yellow leaves, diseased leaves and lateral branches in the lower part of the plant, so as to facilitate ventilation and lightening and reduce nutrient consumption. In general, tomatoes and cucumbers maintain about 16 functional leaves per plant; eggplants and peppers maintain 30-40 functional leaves per plant.
When the tip of a pointed tomato grows to the ear of a predetermined ear, the result is usually 4-6 spikes per plant, leaving 2-3 leaves above the upper ear to remove the top.
â—† Promote fruit setting and fruit thinning
Tomato vigorously promote pollination pollinator-assisted pollination. Eggplant can be used "high yield agent II", "Fructus Ning" and other safe and efficient flower protection agent spray to improve the fruit setting rate. Cucumbers and peppers do not need to use preservatives to help fruit set. The tomato usually leaves 4 or so fruits per ear, removing excess flowers and fruits as early as possible, and removing malformed fruit and each fruit's ear from too large and too small fruits as early as possible to achieve a fruit-shaped and fruit-like effect. .
â—†Scientific Watering Fertilization
Watering should be scientifically watered according to weather, crop conditions and soil moisture. The method of watering with a small amount of water is better. Tomatoes and eggplants are usually watered once every 5-8 days. Cucumbers and peppers are watered once every 3-5 days. Avoid excessive drought and watering too much to promote fruit growth and prevent the emergence of fruit. Tomato cracking phenomenon, increase the fruit rate.
Topdressing promotes "water and fertilizer integration" and "balanced fertilization" techniques, and top-dressing according to the laws of fertilizer requirements and plant growth of different crops, especially to avoid excessive nitrogen fertilizer and insufficient potassium fertilizer to form tomato rot. Fertilization is based on the principle of eating less and more meals. Tomatoes are topdressed once each ear begins to swell. Cucumbers, eggplants, and other crops are usually chased once every 10-15 days. Each time, each acre of water is topdressed with a suitable ratio of N, P, and K to fertilize 5-8 kilograms. Stop top dressing 30 days before picking.
Fertilizer spraying foliar crops in the middle and late stages of spraying fertilizer 4-5 times, 7-10 days apart, sprayed with 0.3% potassium dihydrogen phosphate and 0.5% urea spray, can also spray alginic acid Functional fertilizers, which play a role in quickly supplementing nutrients to promote growth.
Instantly harvested vegetables in open field
The harvest period of eggplant, cucumber, legume bean, kidney bean and Chinese cabbage flower and green cauliflower, rapeseed, garland chrysanthemum, leeks and other crops should be selected in the sunny morning and timely harvest to improve the quality of refurbishment, and the graded packaging should be listed. At the same time do a good job top dressing, watering, fruit thinning and pruning old leaf management.
Pest Control
Pay close attention to the dynamics of pests and diseases, and strengthen the prevention and treatment of diseases such as cucumber downy mildew, powdery mildew and tomato late blight, gray mold, and insect pests such as grasshoppers, whitefly, cotton bollworm, red spider, and tea plant. It is necessary to use low-toxic, high-efficiency pesticides or biological pesticides for prevention and control, and ensure that the safety intervals after application cannot be harvested to ensure product safety.
Dredging Drains to Prevent Flooding
Clean up and clear the drains as soon as possible. If there are no drains, the land and sheds should be cleared up as soon as possible. Exclude the water in the fields as soon as possible after rainfall so that the rain stops flowing. Inspection and repair of the sheds: Inspect the rear slopes, back walls and other parts of the greenhouses and find that the leaking parts are repaired before the rainy season arrives to ensure that no collapse occurs. The storage of insulation and grasshoppers should be inspected and rain protection work should be done.
Xia Qiuyi shed tomato colonization
Colonization by June 10th, when the temperature is high in July-August, the plants have grown and have strong resistance to high temperature. Select the sunny afternoon planting, so that the appropriate depth and density, reasonable density, timely pouring enough water to planting.
Onion colonization
Apply 5000 kg of organic manure per acre. Do not use unripe organic fertilizer. If the source of fertilizer is lacking, 3000 kg of commodity organic fertilizer can be used. Deeply ploughing the soil, fine soil preparation, and planting vigorously growing onion seedlings, so that the density is reasonable, the depth is consistent, and the water is planted in a timely manner.
Qiu Lu exposed celery seedlings
The celery seedlings are planted in the middle and late June, and they are sown after low temperature germination. After soaking for 24 hours, the celery is placed in a distance of 50 cm from the surface of the water. Due to the high temperature and the gradual increase of rainfall during the season, we must raise seedlings in facilities such as greenhouses or small sheds, pay attention to the shading and rain protection of nursery sheds, and leave 80 cm high air outlets on both sides of the shed to facilitate ventilation. Vents and doors are closed with insect screens. City Agricultural Technology Promotion Station Cao Hua
Tips
High-temperature stuffy shed sterilization small prescription
In the clean booth, after the crops are harvested from June to July, the crop residues are removed, the weeds in the fields are removed, and transported outside the shed is buried or burned.
Straw stalks will be used to cut corn stalks, wheat straw, and other crop stalks into pieces of 3 cm to 5 cm in size. Corn cobs, waste materials, etc. will be crushed and then uniformly dispersed in amounts of 1,000 kg to 3,000 kg/mu. In the shed interior.
• Spread organic manure 3000kg-5000kg/mu of organic manure, such as chicken manure, pig manure and cow manure, and spread it evenly on the straw or fully mixed with crop straw. At the same time, mix 30 kg of ternary compound fertilizer (effective content of N, P and K is 15:15:15) or 15 kg of diammonium phosphate. The specific dosage can be decided according to the soil fertility, the type of crops under the crop and the mode of planting.
• Applying fast rot agents such as rot bacteria enzymes into fast rots, mixing 2 kilograms per acre, deep-dip 25-40 centimeters, and making soil suitable for irrigation.
• Irrigate the soil in the shed to make it fully wet. The relative humidity is about 85% (absence of surface water, and the soil can not be dispersed by hand).
? Double-covered mulch or whole piece of plastic film covers the floor and seals the joints. At the same time, the booth is closed and the shed film is inspected to repair the loopholes, maintain the cleanliness and good light transmission.
After the sheds are closed, the sheds shall be kept for 25-30 days in a high-temperature and high-humidity state within the shed, and at least there shall be at least 15 days of sunny weather. During the period of high temperature drenching, rain should be prevented from pouring into the shed. Padding can last up to 5 to 10 days before the next crop is planted.
• Colonization Prepare uncovered membranes to open vents, remove mulching film, and dry sheds. After the surface is wet and dry, it can be prepared for the cultivation of the crop.
if you only have hearing loss in one ear, then you have unilateral hearing loss and you`re more likely to get all the support you need from a single hearing aid. You can wear a single unilateral hearing aid in your bad ear and hear normally with the other one. Because your other ear is functioning normally you will get all the benefits of binaural hearing with just one hearing device.
