Three Factors Affecting Rice Yield Rate
Rice production rate = rice number / rice number * 100%, different food crops have different requirements for their rice output rate, for example, the average rice output rate is about 73%, the highest is 78%; the average wheat output rate is about 85%, the highest 91; Sorghum out of an average rate of about 79% rice, the highest 81%; millet average out of rice rate of about 75%, the highest 78%; average corn out of 93%, the highest 95%. The detection rate of rice output can be quickly measured and analyzed by using a small rice grinder. It is specifically used for testing purposes. The more accurate title is the experimental rice grinder. The level of rice output directly affects the final profitability. What are the factors that influence the rate of rice output?
The first is meteorological factors. After the sowing of rice, the low temperature has prolonged the emergence time of rice. Because the seeds do not germinate in the soil for a long time, some of the greenhouses have the phenomenon of “powdered seedsâ€, resulting in a lower seedling rate, which can easily cause large slow seedlings and make rice. After the birth process is delayed, part of the rice's maturity is not enough and the number of green grains is too large. As a result, the milling quality of rice is affected to a certain extent. Although the yield is higher, the rice output rate is lower.
This is followed by the varietal factors. According to the different maturity, rice is divided into early-maturing, medium-maturing and late-maturing varieties. The accumulative temperature in each area is different, so the ripening period of rice suitable for local cultivation is also different. Localities should be adapted to local conditions, and varieties suitable for the region should be selected in terms of species selection. Inappropriate rice varieties will cause the maturity of rice not directly affect the rice output rate.
The second reason is that the fertilization is irrational. Farmers generally apply inorganic fertilizers and rarely apply organic fertilizers. Inorganic fertilizers, however, some farmers also apply nitrogen fertilizers. This is a hidden problem in rice production. The blind application of nitrogen fertilizer can increase the yield to a certain extent, but the poor application timing and dosage will lead to late-maturing lust, increased disease, and even large areas of lodging, so that the grouted blocked grains are not full, especially branches and grains, causing rice grains. Incomplete, serious impact on the rate of rice.
The above factors are important factors affecting the rice output rate of rice. The above three points can be reasonably controlled except that the weather factor cannot be fully controlled. Therefore, reasonable selection of rice varieties and scientific rice fertilization increase the rice output. The effective method of rate.
