Wang Xiangmin, Shiqiao Village, Yaowangzhuang Town, Funan County, last year made use of the sheds to carry out the production of Shangyu lettuce and Xiajiajiaojiao, with an average yield of 5,000 kilograms of lettuce, an output value of 11,500 yuan, and a yield of 8,500 kilograms per kilo of sharp peppers. The total income of the four-acre shed was 81,200 yuan, the cost was 24,460,000 yuan, and the net income was 56.84 million yuan. Now his main cultivation measures are described as follows:
First, winter wolfberry lettuce
1. Nursery. Selection of disease-resistant, high-yield fine varieties of water hanging silk, in early September to late in the greenhouse sowing seedlings. During the daytime, the management in the greenhouse mainly adopts measures such as the ventilation of the shed film and the shade of the shade to reduce the temperature. At night, when the weather is not overcast, it is the bottom wind. Sub-seedling to the seedling stage must be shaded during the day and try to create an ambient temperature suitable for the growth of lettuce. According to the situation of the seedbed, try to control the watering, not drought or pouring, to prevent the seedlings growers, seedling age 35 days of planting.
2. Colonization. Planted in early October. Before the planting, soil preparation was performed. Mushi rotted 5,000 kg of organic fertilizer and 50 kg of ternary compound fertilizer, then ridged and planted 3500 acres.
3. Management after planting. Immediately after the asparagus planting watering, when the greenhouse temperature exceeds 20°C during the seedling period, air-conditioning and seedlings are started. During the daytime, the greenhouse temperature does not exceed 25°C and nighttime is 3°C to 10°C. After the temperature falls, grass is ready before and after the winter. Curtains are prepared for night-time insulation and are covered with double-film double eyes during the coldest season.
4. Pest control. The control of downy mildew was sprayed with a 500% solution of 64% antivirus, and a sclerotia net spray of 1000 times was used to control sclerotinia. Nematicotin or spray of agricultural streptomycin was used to control soft rot.
Second, early spring pepper
1. Nursery. High-yield, disease-resistant and high-quality hornbeam varieties Haifeng 68 and New Olympic 2008 were selected. They were planted in the cold sheds in Cameroon from late October to early November. The temperature management during the nursery period mainly involves the addition of insulation materials. That is, the double-membrane double borer is used to control the seedlings. When the seedlings grow to three leaves and one heart, the seedlings begin to appear when the buds appear, and the seedling age is about 100 days.
2. Colonization. After the lettuce is harvested, the soil is fertilized in time. Planted in mid-February, the plant spacing is 35 centimeters and 60 centimeters, with one plant per hole.
3. Management after planting.
(1) Water and fertilizer management. After planting, pour water once a day, cultivating 2 or 3 times, and slowly seedling after seedlings. When the door pepper is stable, combined with watering urea 7.5 kg per mu, potassium sulfate 4 ~ 6 kg, fruit harvesting period combined with water topdressing diammonium 15 ~ 20 kg, into the fruit period 7 to 10 days pouring 1 small water, every time after a water chase a fertilizer, each mus of 5 to 10 kilograms each time, potassium sulfate 8 to 10 kilograms, or use red fertilization.
(2) Temperature and humidity management. Seedling during daytime 28°C～32°C, nighttime 18°C～20°C, Resulting period: 25°C～30°C during daytime, 18°C～20°C during nighttime, suitable air relative humidity during growth is 50%～70%, controlled by pouring Water and air release measures to regulate humidity.
(3) Planting adjustment. The following collaterals and aging leaves were removed in time, and the diseased leaves and old leaves were promptly removed in the middle and late stages to facilitate ventilation.
(4) Harvesting. Peppers and peppers should be harvested early to prevent falling. Fruit harvesting needs to be harvested in time to avoid affecting the fruit set on the top.
