Is there any way to increase the yield of rice?

Is there any way to increase the yield of rice? Is there any way to be effective? If you want to increase the yield of rice, you can refer to the following methods: 1. Increase the number of ears. Strong seedlings were cultivated by ①. It provides a good basis for early return to green and early tillering after planting. ② reasonable close planting. According to the planned number of ears harvested and the estimation of the tillering of seedlings after planting, the basic number of seedlings was planted (thrown). ③ promotes early tillering in low position and less tillering in high position. Promote the early emergence of low tillers, open and dry the fields in time after planting enough seedlings, control the invalid tillers with high nodes, concentrate nutrients on the effective tillers of early onset, and improve the panicle rate of tillers. two。 Increase the number of grains per panicle. ① promoted the sturdiness of stem before young panicle differentiation. On the basis of strong seedlings, the necessary nutrients for the steady growth of rice plants should be ensured at the tillering stage in the field, so that the rice stems are strong, the branches of rice panicles are strong, and there is a good foundation for forming large ears. ② provided sufficient nutrients for young panicle differentiation. Usually at the beginning of young panicle differentiation, if the leaf color is lighter, it is necessary to apply "flower-promoting fertilizer" to promote the differentiation to form more spikelets. In the middle stage of young panicle differentiation and development (about 20 days before heading), if the leaf color is light, "flower protection fertilizer" should be applied to reduce spikelet degeneration and improve floret growth rate. ③ adjusted the temperature with water to improve the seed setting rate. In the case of dry and cold weather (such as cold dew wind) in the heading and flowering stage, it can dive to keep moisture and increase temperature, reduce the damage of low temperature and drying to rice, and improve the seed setting rate. ④ increased dry matter accumulation before heading. Pay attention to the supply of nutrients needed for growth before heading, but the growth should not be too prosperous, so as to accumulate photosynthate, ensure that more matter is transferred to the grain after heading, and improve the seed setting rate. 3. Increase grain weight. ① ensures that there are good nutritional conditions in the later stage of young panicle development, so that the husk grows larger and contains more filling material. In the mature stage of ② grain filling, moist irrigation was adopted to maintain roots and protect leaves, resulting in more photosynthates and good grain plumpness. During the growing period of rice, ③ combined with spraying Shuofeng 481 plant growth regulator can promote leaf formation and growth, increase photosynthetic capacity, promote grain filling speed, increase grain weight, increase grain protein and nitrogen acid content, improve quality, shorten growth period, promote grain maturity, and win valuable time for planting double cropping rice.
