In the countryside, almost every household will grow winter melon, which can not only be stewed, but also fried and fried, is a good dish. I believe that friends who grow winter melons hope that their winter melons can be produced with high yield. It is very important to implement fertilizer. The following small series will tell you the three main points of fertilization!

One, How can winter melon fertilize and produce high yield?

1. Master the amount of fertilizer needed

The roots of winter melon are strong and developed, and have strong ability to absorb fertilizer. They need a large amount of fertilizer and strong ability to withstand fertilizer during the whole growth period. Fertilization is based on organic fertilizer, combined with topdressing compound fertilizer. In the early stage of winter melon, the amount of fertilizer needed was less, and the roots were mainly nitrogen. The fruiting stage of melon was the peak of fertilizer requirement, and it needed to absorb a large amount of phosphorus and potassium. The peak of nitrogen absorption was in the flowering and melon stage, and the phosphorus was in the seed. During the developmental period, potassium is in the period of winter melon expansion. In the whole growth period of melon, the three elements of nitrogen, phosphorus and potassium should be applied together. Generally, for every 1000 kilograms of winter melon, about 1.0~3.6 kg of nitrogen, 0.6~1.5 kg of phosphorus and 1.5~3.0 kg of potassium are used, and the absorption ratio is about 1:0.53: 1.13.

2, apply enough base fertilizer

The yield of winter melon is high, and the amount of fertilizer needs to be large. To obtain high quality and high yield, it is necessary to apply sufficient base fertilizer, apply 5000~7000 kg of decomposed organic fertilizer rich in various nutrients and 50~75 kg of compound fertilizer per mu, mix and apply or Do it when you are doing it.

3, winter melon top dressing

(1) Slow seedling fertilizer: After the melon seedlings are slowed down, the topdressing is started when the melon seedlings are 5~6 true leaves, and the melon formula fertilizer is 5~8 kg per acre.

(2) Promoting melon fertilizer: After the melon is stabilized, the melon fertilizer is chased in time. This topdressing is the key to high-yield and high-quality melon, and the compound fertilizer is applied for 10~15 kg per mu.

(3) Topdressing in the melon period: The melon expansion period is the period in which the melon needs the most fertilizer and water, and it is also the key period for determining the yield of melon. It should be topdressed about every 15 days after the melon is promoted. Fertilizer 30~40 kg.

(4) Foliar topdressing: Spray 600~800 times of amino acid fertilizer every 7~10 days in the period of melon expansion, add 0.2%~0.5% potassium dihydrogen phosphate to prevent premature aging, prolong the melon period, and make the melon quality High yield has obvious effects. Other nutrients can also be applied as needed.

Second, the time of winter melon sowing

If you grow winter melon, it can be in spring or autumn. If it is spring, it is in February, and if it is autumn, it is probably in July. Breeding in advance, and then waiting until the colonization is good.

Third, the melon

If you want to produce good winter melon, you should carry out appropriate sorting, and generally leave a main vine to avoid the prosperous situation. Too much result is actually unfavorable for the overall load. About a vine grows 20 leaves and you can start to keep the melon. There should be no more than three melons on the main vine. If there are too many, it is prone to overload.
