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, the land preparation:
The plots that have not been planted with melon crops within three years are best selected for paddy field rotations, which can effectively reduce pests and diseases. Get up to 3 meters (baggage ditch). In the planting trenches, sufficient base fertilizer was applied, and the decomposed organic fertilizer in Mushi was 1000-2000 kg, 30 kg of ternary compound fertilizer, 50 kg of phosphate fertilizer, and 10 kg of potash, mixed with the soil. At the same time, it is best to combine 50-100 kg of lime with lime. 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% formaldehyde 150 times solution for 30 minutes, rinse with water 3-4 times, soak the seeds for 6 hours, and dry seed epidermis, and wrap them in damp cloth. Around °C environmental germination (similar to rice seed). Seeds can be sowed after 2-3 days of budding. 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, they can be planted and can also be used according to local customs. When planting, the temperature is stable at more than 10°C, and the spacing is 0.4m-0.5m and 2.5m. The single-row planting 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 a seedling fertilizer, and water and fertilizer were appropriately added as the seedlings were later treated. 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 vine, with the main vine guagua, 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 vines when 5-6 leaves topping, stay Three side vines, two vines, one for each vine, and the other not for melon. The latter kind of pruning method should be suitable for sparse planting, with a spacing of 0.5-0.6 m. After the melon seated, leave 8-10 leaves topping above the seat of the melon seat. Exfoliate as soon as possible. From melon ripening to ripening need to turn melon 2-3 times, so that the appearance of melon appearance evenly beautiful.
IV. Pest Control:
1. Fusarium wilt: Rotation or grafting is the most effective preventive measure. Chemical control can use 50% carbendazim 500 times solution and 3% Guangwa Lingshui agent 500-600 times for irrigation. Irrigation once a week after planting, once every other week, even irrigation three times, have a certain preventive effect.
2. Diseases: Use 70% Mancozeb Zinc Wettable Powder 800 times, Shuangling A Manganese Zinc 500x, 72% Race Lotion 1000x, 64% Kill Mite 600-800x Solution or 50% Ank 2500 -3000 times the liquid, anti-virus scorpion, Prek, the world's higher pharmaceutical control. Apply the affected area with a 10% concentrated anti-virus solution and have a good therapeutic effect.
3. Downy mildew: It can be controlled by agents such as radommil, ank, and metalaxyl manganese zinc.
4. Anthrax: Controlled by mancozeb, Shibaoke.
5. Insect pests: mainly locusts, thrips, red spider, melon pupa, Spodoptera litura, etc., can be selected imidacloprid (Dagong Chen, Jin Dadi, etc.), rice acaricide (such as the killing cricket 2000), Kaiwei 167 Prevention.
V. timely harvest: 25-29 days after pollination can be listed on the spring melon, gourd about 22-25 days.
