I. Field Management at the Seedling Stage
(1) Temperature management. After sowing, the temperature is kept at 28~C-33~C during the day and 21~C-23~C during the day, and 24~C-26~ during the day after the seedlings (2, 14~(2-18~C) at night.
(2) Grafting period management. Black seed pumpkin two cotyledons flattened, cucumber seedlings were broken when the grafting, after grafting seedling cover small arch shed insulation moisture, shed temperature to maintain 28-30 ~ C, humidity above 95%, and shading for three days to facilitate wound healing, 7 After days, the cucumber seedlings were cut off and the grafted seedlings were grown independently.
Second, planting
(1) Planting field bases. Mushi high-quality farmyard fertilizer 12000 kg, superphosphate 100 kg, deep-turn 30 cm, flattening, forming a 50-meter-wide management line, planting rows of 70 cm double ridges, concave font, ridge width 25-30 Centimeter, ridge height 15-20 cm, and covered with mulch.
(2) Requirements. 3-4 true leaves or seedlings of the seedlings for 30 days, planted on a continuous sunny morning in the middle of the 11th, planting spacing 26-30 cm, planting not less than 4,000 per mu; grafted interfaces do not touch the soil surface; Cover seedlings well to prevent the hot gas in the membrane from spilling and injuring the seedlings, and watering them to high ridges under the intimal membrane of the concave ridges. And in the management of the ground floor of the waste film, dampening temperature.
Third, the management after planting
(1) Temperature. Before easing the seedlings, the main purpose is to raise temperature and promote rooting. The shed temperature is maintained at 28-30 days during the day (2, 13-15 C at night, before the thrilling festival, the daytime shed temperature reaches 30~(2). Combining with the temperature of disease control, the temperature rose into March, and ventilation and grasshoppers were used to control the greenhouse temperature, and temperature and humidity were used to prevent and control the disease.
(2) fertilizer and water. After the cucumbers are thrown, the water is generally not watered until late February. There are water shortages and droughts. The water can be poured under the ridge membranes in sunny mornings and drained after 3 days. In late February, the people enter the harvest period and plants need fertilizers. The amount of water increases every 10-15 days. Pour 1 water, and apply 10 kg of urea or 20 kg of ammonium sulfate each time. The melon grows to about 10 cm. Spray 1% (red) white sugar solution plus 0.4% potassium dihydrogen phosphate mixture every 6 Once a day, the melons are straight and taste good, but also increase production. During the prosperous period of the melon, carbon dioxide solid gas fertilizer is applied at 10 grams per square meter.
(3) Pest control. It is mainly used for five-disease pests: use 75% chlorothalonil WP 600 times, or 500-fold dilution of Dasheng M-45 to prevent downy mildew; use 20% Triadimefon 2000 times or agricultural resistance “120†Or 2% Wuyimycin 150 times plus 50% carbendazim 600 times to control powdery mildew; choose 40% EB aluminum wettable powder 300 times liquid to control disease; choose Dasheng M-45 500 times fluid plus 50% fast keratin 2000 times liquid, control botrytis; use 72% of agricultural streptomycin 4000 times or 77% can kill wettable powder 400 times, control bacterial leaf spot disease. The above-mentioned disease prevention and treatment should be used alternately, once every 7-10 days. With 10% of the net or 40% omethoate 1000 times, control melon, whiteflies, ticks.
