在水稻生产上,选用良种,是全面落实农业“八字宪法”的一项重要内容。大家知道,水稻产量的构成因素是穗数、粒数和千粒重。我省高产单位的实践表明,要获得千斤以上的产量,要求每亩有35～40万穗,每穗实粒数50～60粒,千粒重25～26克。而如果能够在保持上述穗数和粒数的基础上,把千粒重提高到30克,产量就可达到1200斤。
In rice production, the selection of fine varieties is an important part of the full implementation of the “eight-character constitution” of agriculture. We all know that the composition of rice yield is the number of spikes, grain number and 1000-grain weight. The practice of high-yielding units in our province shows that in order to obtain a throughput of over one kilogram, there are 35-40,000 spikes per acre, 50-60 spikelets per spike and 25-26 g grain weight per spike. If we can maintain the number of spikes and the number of grains on the basis of the thousand grain weight increased to 30 grams, the output can reach 1200 pounds.
