Fertilize you and grow fast. I knew it.

Here, watermelons in greenhouses or small arches are the main products, and they have been registered as national geographical indication trademarks: "Guandiwa" watermelon, "Guandiwa" watermelon and melon were awarded the honorary titles of "Top Ten Famous Melons in Yantai" respectively. Watermelon is big and sweet, with few deformities. The yield and quality of watermelon are closely related to fertilization, especially the sweetness of watermelon, the amount of fertilization and the type of fertilizer are decisive factors. Watermelon production is high and fertilizer demand is large. Every 1000 kg of watermelon requires 3 kg of nitrogen.

Although the demand for fertilizer in watermelon is relatively large, its root system is fragile and easy to burn because of high fertility. During the whole growth process of watermelon from seedling to maturity, the absorption of various fertilizers has changed to varying degrees. Fertilization is necessary to make watermelon grow big and sweet. About ten kilograms of urea per mu. And cake fat. You can also use some animal droppings. Don't covet his large number. Too much, too little. Better leave a good one-on-one As long as the soil is wet. Compound fertilizer: Watermelon needs a compound fertilizer with low nitrogen, medium phosphorus and high potassium, which can be used as a compound fertilizer with a mass of about 70-80 kg per mu or as a single nitrogen, phosphorus and potassium fertilizer, such as 20 kg of urea for nitrogen fertilizer, 80- 100 kg of calcium superphosphate for phosphate fertilizer and 25-30 kg of potassium sulfate for potassium fertilizer. When we apply basic fertilizer to watermelon, we mainly use decomposed organic fertilizer, and the amount of fertilizer per mu is about 4000~5000 kg, and urea 15~20 kg. This nutrient is very suitable for changing soil fertility.

Let me just say this briefly. It is most suitable to make 3000 kg of decomposed farm manure per mu, which can make the soil loose, breathable and organic, and add special fertilizer for watermelon in the later stage, so that watermelon grows sweet and big. The family is farming in the countryside, and a good way is to apply base fertilizer and some phosphate fertilizer and organic fertilizer until the watermelon seedlings grow up.
