The latest course on fertilization Management of Watermelon

Watermelon can be said to be a kind of national fruit in our country. The demand of watermelon in summer is very large. There are many varieties of watermelon in our country, and the planting area is also expanding. It is a kind of fruit with high economic value. When planting watermelon, fertilization is very important, which is directly related to the yield of watermelon. So the editor brings you the fertilization management technology of watermelon today, let's take a look at it!

1. Farm manure

Farm manure is used as base fertilizer before watermelons are planted. Before planting, it is necessary to apply about 3500kg farm manure per mu with land preparation work, and the farm manure must be fully mature to prevent excessive heat from burning watermelon seedlings. Then in the watermelon extension period, fruit setting period and other periods should also apply appropriate farm manure. Enhance the growth ability of watermelon, strengthen stress resistance, and improve the quality and yield of watermelon. Should pay attention not to apply chemical fertilizer alone, pay attention to the amount, to prevent the reduction of sugar content in watermelon, resulting in a decline in quality.

2. Apply potash fertilizer

Potash fertilizer is very important for the growth of watermelons. Proper application of potassium fertilizer can promote watermelon metabolism, synthesis of carbohydrates, improve nutrition transport capacity and so on. And it can also enhance the disease resistance and quality of watermelon. Add about 8kg potash fertilizer when applying base fertilizer, and then pay attention to the proper topdressing of potash fertilizer in the melon-bearing period. This can obviously improve the quality of watermelon and increase the yield.

3. Increase the application of boron fertilizer

There is also a certain demand for trace elements in the growth of watermelon. One of the most important is boron fertilizer, reasonable topdressing boron fertilizer can effectively reduce the thickness of watermelon peel and avoid the hollow phenomenon of watermelon. Make watermelons into high-quality melons with thin skin and sweet flesh. However, we should also pay attention to the application of chlorine fertilizer, watermelons do not need chlorine fertilizer, if the application of chlorine fertilizer, it will reduce the sugar content of watermelons, resulting in a decline in quality.

4. Cake fertilizer application

When the fruit of the watermelon grows to the size of a ping-pong ball, dig a topdressing hole about 12cm from the main root of the watermelon plant. Then each plant is fertilized with appropriate amount of cake fertilizer, and then covered with soil and watered. Appropriate amount of cake fertilizer can promote fruit expansion and improve growth rate. However, we must pay attention to control the dosage, do not apply too much, otherwise it will easily lead to the excessive growth of watermelon, reduce the fruit setting rate, and produce bad melons with thick skin and sour flesh.

5. Foliar fertilizer

Foliar fertilizer is to improve the growth ability of watermelon leaves, and foliar fertilizer is mainly carried out in the period of extension and expansion. Generally, spraying 50kg per mu, about once a week, lasting about a month, can significantly improve sweetness. When spraying foliar fertilizer, we should pay attention to comprehensive, to ensure that each leaf, front and back can receive medicine evenly. Enhance the photosynthetic capacity of leaves, improve the accumulation of nutrients, and promote the growth of watermelon.

Be sure to pay attention to the location and depth when fertilizing. Do not be too close to the plant to prevent burning the plant, too far will reduce the fertilizer efficiency. The depth should be kept around 10cm. If the fertilizer is too shallow, the volatilization rate of fertilizer will be accelerated, which will not only harm the plant, but also decrease the fertilizer efficiency. That's all for today's introduction. This article is for reference only. I hope it can help you all.
