High-yield Winter Melon Must Master Fertilization Techniques

1. The growth period of the base fertilizer winter melon is relatively long compared to other vegetables, and sufficient base fertilizer should be applied before planting. Especially during the growing season of winter melon, it is not easy to fertilize with rain. It is very important to apply sufficient base fertilizer. The base fertilizer is mainly decomposed farm manure, with about 6000 kg applied per mu. If the soil is infertile, the appropriate amount of compound fertilizers such as potassium sulfate can also be added. Spread it on the ground, turn it about 30 cm deep, and rake it flat. If the soil is too acidic, it should be mixed with an appropriate amount of lime.

2. Seedling fertilizer At the seedling stage of winter melon, it is necessary to pay attention to the application of an appropriate amount of seedling fertilizer. The seedlings and fertilizers are generally based on small water and light fertilizers to avoid excessive fertilizers and excessive heat, which can cause the seedlings to burn out. About seven days after the seedlings are planted, the plants need to be poured with the appropriate amount of slow seedling water when they are slow seedlings. If the base fertilizer is applied too little, after the seedlings slow down, the fertilizer can be applied lightly once. Fertilizers are applied with decaying manure water with a concentration of about 20%, and urea or compound fertilizers can also be used for hole application. The amount must be strictly controlled and not excessive.

3. Cultivation Before the winter melon has been pumped, the amount of top dressing should be kept at about 35% of the total amount of top dressing. The main purpose of the fertilization work during this period was to promote the growth of vine leaves, but we should also pay attention to control the concentration and dosage. Avoid excessively causing dark green leaves and short internodes. If the basal fertilizer is sufficient and the plant grows well, then no fertilization is required. On the contrary, if there is too little fertility, when the seedlings have about 5 leaves, they need to ditch and fertilize. Apply an appropriate amount of compound fertilizer per mu, and control the fertilizer water, especially nitrogen fertilizer, after the female flowers grow and before the fruit is set, to avoid the stems and leaves from growing and causing the melon phenomenon.

4. Flowering and fruiting fertilizer When fertilizing during the flowering and fruiting stage of winter melon, the dosage should be kept at about 65% of the total top dressing. Fertilization at the flowering and fruiting stage has a great influence on the yield of winter melon. Usually it should be done after sitting melon, to avoid the phenomenon of falling flowers and fruits, and to ensure complete nutrition. Then after the melon sits firmly, it is necessary to apply the medicinal fertilizer in time. In the middle and late stages of fruit expansion, a small amount of top dressing should be used as the principle of fertilization, and top dressing should be done every half a month or so. Each time about 25 kg of high nitrogen and potassium compound fertilizer. Adjust the dosage and frequency according to the fertilization in the early stage of winter melon and the harvest time.
