The cultivation technology of small gifts of watermelon is basically the same as that of ordinary watermelon, and the cultivation techniques are as follows:
First, site preparation: Choose a plot that has not been planted with melon crops within three years. It is best to implement paddy field rotation in rice paddies, which can effectively reduce the occurrence of pests and diseases. Get up to 3 meters (baggage ditch). Application of base fertilizer in the planting furrow, Mushi decomposed organic fertilizer 1000 to 2000 kg, 30 kg of ternary compound fertilizer, 50 kg of phosphate fertilizer, 10 kg of potash, mixed with the soil. At the same time, it is best to combine 50 to 100 kg of lime in the field. If the organic fertilizer is sufficient, the amount of fertilizer can be adapted to reduce, and it can be managed according to the local cultivation habits.
Second, nursery: In order to achieve Miao Qi Miao Zhuang, to facilitate unified management, while saving seed consumption, the best nursery to avoid live. Put the seeds in 50% carbendazim 500 times solution or 40% aldehyde 150 times solution for 30 minutes and rinse with clean water for 3-4 times. Soak the seeds for 6 hours. Dry seed seed surface water and wrap it in wet cloth. Around Â°C environmental germination (similar to rice seed). 2 to 3 days after germination can be sown. The nutrient soil can be mixed with paddy soil and decomposed organic fertilizer by adding 6 to 4 to reduce the amount of zedoline. After sowing, nutrition cups should be covered with plastic film to prevent rainwater scouring and moisturizing until sprouting. After emergence, the temperature and humidity are mainly adjusted. If the temperature is too low or the rain is too large, cover and keep warm and rain.
Third, field management: When the seedlings have two true leaves can be planted, but also according to local customs. When planting, the temperature is stable at more than 10Â°C, and the spacing is 0.4m to 0.5m and 2.5m. The single line or local habits can be used, and about 500 plants per mu are agreed upon. One week after planting, 0.2% urea water or dilute human fecal urine was used once as seedling raising fertilizer. When melons have egg size, 20 kg of compound fertilizer can be applied per acre, and 10 kg of potash fertilizer can be used to apply fertilizer and water according to local fertilizer conditions or planting habits.
The pruning method can use two vine pruning or three vine pruning. The two vine pruning is the main vine and the base of a robust side vines, the main vines, melon, the use of this pruning method should be suitable for close planting, spacing 0.4 meters can be used; three vine pruning is the main vine when 5 to 6 leaves to top, stay Three side vines, two vines, one for each vine, and the other not for melon. Use the latter kind of pruning method should be appropriate sparse plant spacing from 0.5 meters to 0.6 meters is appropriate. After the melon seated, 8 to 10 pieces of leaves were topping at the seat of the melon section. Exfoliate as soon as possible. From melons to ripening, it is necessary to turn melons 2 to 3 times to make melons look even and beautiful.
IV. Pest Control:
Fusarium Wilt: Rotation or grafting is the most effective preventive measure. Chemical control can be used 50% of mycotoxin 500 times and 3% Guangwa Ling agent 500 ~ 600 times rotation Irrigation. Irrigation once a week after planting, once every other week, even irrigation three times, have a certain preventive effect.
Blight: Use 70% MnZn WP 800 times, Shuangling Mn Zn 500x, 72% LD 1000x, 64% TB 600 800 800x or 50% AK 2500 3000 3000x , Antivirus, Preco, advanced pharmaceutical control. Apply the affected area with a 10% concentrated anti-virus solution and have a good therapeutic effect.
Downy mildew: It can be controlled by agents such as radommil, ank, and metalaxyl manganese zinc.
Anthracnose: Prevention and treatment with mancozeb, Shi Baoke.
Insect pests: mainly locusts, thrips, red spiders, melons, Spodoptera litura, etc., can be selected imidacloprid (Da Gong Chen, Jin Dadi, etc.), rice acaricide (such as killing cricket 2000), Kaiwei 167 prevention.
V. timely harvest: Spring pollination 25 to 28 days after the market can be listed, about 22 to 25 days of autumn melon.
