Late rice due to improper selection of varieties, unreasonable planting density, excessive application of nitrogen fertilizer, excessive waterlogging, too late harvesting, damage to pests or diseases, etc. may cause lodging, resulting in rotting, withering, and grain sprouts. Half-hearted and cut production. Therefore, preventing the lodging of late rice is an important part of seizing the food harvest. The following "five strokes" can prevent late rice lodging. The first is to use fertilizer resistant varieties. For example, fertilization resistant varieties with semi-dwarf, thick stems, well-developed roots and erect leaves are selected. The lodging resistance of indica and japonica is better than that of hybrid rice, such as Yinjing and Zhanhua. The second is to strengthen fertilizer and water management. The use of formula fertilization technology, the appropriate amount of nitrogen fertilizer, a reasonable increase in phosphorus and potassium fertilizer, a small amount of fertilizer such as silicon fertilizer. In the rice growing period, shallow wet intermittent irrigation method should be adopted. In the booting stage, the water layer can be properly deepened. After heading, the shallow water layer should be kept ground. Dry field is an important measure to prevent the lodging of rice. In the late stage of late rice, drainage can be used to control ineffective allocation, improve the soil environment, enhance the vitality of roots, and make rice seedlings grow steadily. When drying in the fields, the principles of “sunny to unequal seedlings†or “matured to unequal time†should be adopted, combined with the application of potash fertilizer and uniconazole, so as to inhibit the elongation of seedlings during the internode and to make the seedling section Between the thickening, anti-fall effect is better. The third is reasonable close planting. When transplanting, it is not rare and dense, constructing a reasonable group structure can prevent the population density is too large, ventilation and light is good, the stem and leaf tissue are old and healthy, and the resistance to diseases and insect pests and the lodging resistance of the stem are enhanced. Fourth, timely prevention and control of pests and diseases. For the control of sheath blight, 30 grams of Jinggangmycin can be used per mu or 500 ml of 43% Hericel. To control rice blast, 40% rice bran 70-105 grams, or 2% kasugamycin 100 grams per mu can be used. For the prevention and control of Scarabae and Saponins, 10 ml of 20% chlorantraniliprole can be used per acre, or 35 ml of 5% fipronil. To control rice leaf roller, 40% profenofos 70 ml or 1.8% abamectin 100 ml can be used per mu. For the control of rice planthoppers, 50 grams of 20% buprofezin per acre can be used, or 20 ml of 10% nitenpyram can be used. When using the above agents, 60 kg of water must be sprayed or mixed. The fifth is to harvest in time. Prevent overly mature and lodging.
