Watermelon balanced fertilization yield increase sweetening
Although the market conditions of watermelons have been fluctuating in recent years, many watermelon farmers still plant watermelons of a certain size every year because watermelons have a long period of growth and are effective. How to increase the yield of watermelon and increase the sweetness and increase the economic benefits? The specific approach to choose organic fertilizer and potassium sulfate fertilizer. Watermelon sown at the same time, the application of different fertilizers have great differences in their sweetness. Therefore, when using watermelon basal fertilizer, organic fertilizer and potassium sulfate compound fertilizer should be prepared. The formula is balanced with fertilizer application. The root system of watermelon is relatively developed, and the function of absorbing fertilizer is strong. To improve the yield and quality of watermelon, it is necessary to provide multiple compound fertilizers in time. According to the study of the agricultural scientific research department, the ratio of absorption of NPK to watermelon is 3.1:1:3.5. When applying basal fertilizer in Daejeon, 2500 to 4000 kg of organic fertilizer should be applied to farms per acre, or 150 kg of commodity organic fertilizer, or 100 to 150 kg of cake fertilizer, with NPK being 18%, 10%, and 20% (including Sulfur compound fertilizer 40 to 50 kilograms is applied 15 minutes or less before the seedlings are planted. After the seedlings of watermelon are slowly growing, the seedling fertilizer, vine spread fertilizer, and swelled manure fertilizer should also be applied in divided times, with particular emphasis on the application of expanded manure. At the same time, according to the seedlings outside the roots to top-dressing, spraying 0.5% urea, 0.2% potassium dihydrogen phosphate and 0.1% Sonic boron solution, respectively, also need to spray.
