1, timely and dry. If the plants are not dried when they are planted, they should be dried at a position 30 cm above the grafting site in time and cut off the above sections. For excessive leaves and twigs on the trunk, the leaves should be properly removed (cutting off 2/3 of the leaves or all the leaves) to reduce evaporation and promote survival.
2, soil conservation. After the newly planted citrus seedlings have been poured with enough water, they should pay attention to drought protection and seedling protection, and cover and protect the seedlings, and can use straw, wheat straw, etc. to cover the trees. Cover thickness 5-10 cm, covering more than 80 cm in diameter.
3, pest control. When spring shoots are 1 cm long, 800 times mancozeb is used to prevent scab. At the same time, the prevention and cure of spider mites is good. When there are more than 2 spider mites per leaf, they are promptly treated with acaricide.
Second, the results of the tree management
1, spring pruning. Trees that haven't finished pruning in the spring can continue to be pruned, and it is best to end in the middle of April. At the same time, the initial result tree is opened.
2, preserved fruit 1 spray surface fertilizer. Spraying foliar fertilizer before flowering is very beneficial to improve flower bud quality. Formula: 100 pounds of water + 2 boron fertilizer + love Shi high potassium fertilizer 100 grams (2 bags) for foliar spray. Once every 7-10 days, continuous spray 2-3 times.
2 flower spray pharmacy to protect the fruit. In the flower Xie 3/4, love to receive more than 10 ml (1 bag) watered 80 kg +2 two urea foliar spray; or with gibberellin (9,020) 1 g watered 40 kg +0.8 phosphoric acid Potassium dihydrogen + 0.8 borax was sprayed once.
3 wipe bud control tip. When the spring tip is long enough to distinguish buds, 1/3-2/3 nourishment is erased, and 3-5 leaves are left to pick up the nutrient tip to reduce the nutrient consumption and promote leaf maturation. fruit.
4 soil coverage. During the period from May to July during the growth of citrus fruit and physiological fruiting, it is prone to high temperature and dry weather, resulting in shedding of a large number of young fruit. Therefore, from April onwards, the citrus groves will be covered with straw or wheat straw or covered with a garden covering a depth of 8-10 cm. This will maintain and stabilize the soil moisture, improve the micro-ecological environment of the orchard, and reduce flowering and fruiting.
Third, pest control priorities 1, in early April and mid-April with 90% trichlorfon 800 times canopy spray to prevent flower buds.
2, Spring shoots grow about 1 cm long and after the flower Xie once sprayed 80% mancozeb 800 times to control orange scab; at the same time pay attention to control of whiteflies, spider mites and other citrus pests.
Plasma Sterilizer
Plasma sterilizer is to sterilize by hydrogen peroxide low-temperature plasma.Through sterilization,a certain method is used to inactivate various microorganisms on medical instruments and surgical instruments,thereby achieving the purpose of sterilization.
1,Medical plasma sterilizer: sterilization temperature of 50°C± 5°C,low temperature and no humidity,no damage to the sterilization articles and equipment,can extend the life of precision instruments.
2.Medical plasma sterilizer green and environmental protection:hydrogen peroxide solution is used as sterilizing agent,no toxic substance remains,no drainage or exhaust is required,no damage to the operator's body,and special filters for high efficiency can be applied to the air intake and exhaust ports.Absorption of H2O2 from the process of vacuum rejection will result in zero pollution to the environment.
3.Medical plasma sterilizer sterilization stability:The sterilization chamber is made of aluminum or stainless steel,which has advantages of anti-corrosion and thermal conductivity,which makes the temperature of the sterilization chamber more balanced and effective, and ensures that H2O2 maintains 100% of the gas throughout the process.The hydrogen peroxide low temperature storage system ensures that the hydrogen peroxide concentration is stable and effective and does not volatilize.
4.High sterilizing efficiency:The design of a rectangular sterilization chamber makes it possible to load more instruments at a time and make the use of the sterilization chamber more convenient.
