Wheat seedling watermelon cultivation points
Wheat bran watermelon planting is relatively late, the melon production period is at the end of the early melon, at this time the price of melon rose, easy to sell, can increase planting income.
1. Choosing the mouth of a wheat stubble plant that has not been planted for more than 5 years to reduce the damage of watermelon blight and soft rot.
2. Soil preparation Fertilization After the wheat is harvested, it is immediately sited to make a ridge 1.5 meters wide or 3 meters wide, and a 40 cm wide ridge and a 25-30 cm deep groove to be prepared for drainage and irrigation. Before the site preparation, the basal fertilizer was re-used, mainly phosphorus and potash fertilizers, nitrogenous fertilizer supplements, and trace element fertilizers were mixed. Generally, 4000-5000 kg of organic fertilizer was fully decomposed per mu, 25 kg of superphosphate, 10 kg of urea, and 5-7 multiple compound fertilizer. kg.
3, sowing and transplanting According to the consumption habits, select the resistance to disease, harvest, high quality, resistant to transport the fine varieties, such as disease-resistant Tianbao Wang, Jin Hongbao, Admiralty Guanlong and so on. Take the way of raising seedlings with nutrition to advance the growth period. Sow in mid-May, sow 2 cm of fine soil and cover plastic film at night to remove the film. Add shading equipment to prevent strong light at noon. Wheat bran watermelon breeding is in early summer, the high temperature, easy to cause melon seedlings grow long and prosperous, not after the transplanted sinking growth. Therefore, watering should be controlled during nursery, especially to prevent heavy rain. Transplanting seedling age should not be too large, about 20 days is appropriate, when watermelon has 2 leaves 1 heart or 3 leaves. 5 to 7 days before transplanting, the thin film seedlings were uncovered, with a ridge width of 1.5 meters, a single row, a ridge width of 3 meters, and a double row planting at a plant spacing of 0.6 meters, and 700-800 plants per acre. Appropriately shaded within 3-5 days after transplanting.
4. Field Management After the transplanting of wheat, watermelons are in summer, and there are more rainwaters. Watermelon fruit set when the size of the fist is generally topdressing urea 5 kilograms, potassium sulfate 10 kilograms or multiple compound fertilizer 15 kilograms, timely watering top dressing, promote watermelon enlargement. The pruning was started 10-15 days after transplanting, and the two-vine pruning method was adopted so that the stems and leaves of plants were evenly arranged and grew steadily. According to the growth trend of wheat and watermelon, different pressure vines are adopted, and the growing trend is over-prosperity and dark pressure; the growth is too weak and the pressure is clear. Generally, the top ten to fifteen leaves of the melons are topping to control the growth of the shoots. After the female flowers of watermelon were opened, artificial pollination was performed. The male flower that was taken open before 7 o'clock in the morning touched a few on the female flower. This can promote melon production and increase production by 20%. Wheat bran has more pests and diseases, and it should be prevented and treated as soon as possible.
