1. The effect of spraying potassium dihydrogen phosphate in the middle and late stages of rice growth: Potassium dihydrogen phosphate is a high-concentration quick-acting phosphorus-potassium compound fertilizer. Spraying rice in the late and late stages of growth not only prolongs the maintenance of higher chlorophyll content in the leaves, but also enhances its photosynthetic capacity and improves the rate of spike formation. It can also promote grain filling during ripening. Improve the seed-setting rate and 1000-grain weight, increase the resistance and cold resistance of rice, and create conditions for stable yield and high yield of rice 2. The optimum period and amount of potassium dihydrogen phosphate sprayed on rice: The rice tillers, booting and heading stages are sensitive to phosphorus and potassium. Potassium dihydrogen phosphate can be sprayed. Before and after the rice is full-headed, it is best to spray 2 or 3 times continuously and the interval is 10 days. In general, 150-200 g of potassium dihydrogen phosphate and 50 kg of water are applied per acre (ie, 50-60 g of potassium dihydrogen phosphate per pot of water). Spraying time is when the foliage is not dew in the afternoon, spray evenly with a spray nozzle, and avoid excessive burning. At the same time, when potassium dihydrogen phosphate is sprayed, an appropriate amount of urea can be selectively added according to the seedling condition (spraying concentration is about 1%) to make up for insufficient nitrogen fertilizer, and the effect is better. 3, rice spraying potassium dihydrogen phosphate should pay attention to matters: 1 Avoid excessive concentration, and spray the remaining liquid spray repeatedly, resulting in burning leaves. 2 When potassium dihydrogen phosphate is sprayed, avoid mixing other pesticides at random, resulting in a decrease in pesticide control effectiveness. 3 heavy rain after spraying, should be re-spray once.
