Watermelon clever fertilizer taste sweet

The same variety of watermelon, fertilizer applied different, melon flavor is also different. Watermelon fertilization pays attention to a lot, in order to want melons to taste the United States, we must first apply fertilizer. In the growth process of watermelons, chlorine-containing fertilizers such as ammonium chloride and potassium chloride are generally not applied. After applying these fertilizers, the taste of the melon will not only be lightened, but also it will be very easy to rot. When cultivating watermelon, a large amount of nitrogen fertilizer such as urea should not be applied, and only a period of time before the cucumber can be used to apply nitrogen fertilizer. After sitting on the melon, the absorption of potassium by the plants increased greatly. In the stage of dehydration, the absorption of nitrogen and potassium was approximately equal. In the stage of watermelon enlargement, the absorption of potassium reached the peak; In the mature stage, the absorption of nitrogen and potassium by plants was significantly reduced, while the absorption of phosphorus was significantly increased. When fertilizing, the application rates of nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer were as follows: seedling stage 4:1:4, extension period 3.5:1:1.8, and growth period 3.5:1:4.5. In the cultivation of watermelon, human urine should not be used in large quantities. When applying nitrogen fertilizer, try to keep away from the roots as much as possible. You can apply more decomposed chicken manure, sheep manure, cow dung, or special potash for watermelon, so that the watermelon will be big and sweet. .
