Although the market of watermelons has been mixed up and down in recent years, many watermelon farmers still plant a certain area of ​​watermelon every year because the growth period of watermelon is not very long and effective. How to increase the yield of watermelon and increase the sweetness and improve the economic benefits?
Choose organic fertilizer and potassium sulfate fertilizer. In the same period of watermelon planting, the sweetness of the different fertilizers is very different. When using watermelon base 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 multi-component compound fertilizer in time. According to research by the agricultural research department, the absorption ratio of NPK to water is 3.1:1:3.5. When applying base fertilizer in Daejeon, 2500-4000 kg of organic fertilizer should be applied per acre, or 150 kg of commercial organic fertilizer, or 100-150 kg of cake fertilizer, and 18%, 10%, 20% with NPK. The compound fertilizer of 40% of sulfur is applied to the ditch or hole below 15 cm of the soil surface about 15 days before the seedling is planted.
After the watermelon is slowed down, it is also necessary to apply the seedling fertilizer, the extension of the manure fertilizer, and the expanded melon fertilizer in a divided manner, especially focusing on the application of the expanded melon fertilizer. At the same time, according to the seedling roots outside the top dressing, spray 0.5% urea, 0.2% potassium dihydrogen phosphate and 0.1% Suile boron solution, or spray.
