水稻产量是由单位面积穗数、每穗颖花数、结实率和千粒重等四个因素所构成。为了预测产量和检验各个栽培措施的正确性,必须了解各个构成因素的形成过程并进行预测。 本试验是以我校农民教师刘志嵩同志培植的早、晚稻高产试验田为对象,就几种穗数预测方法进行检验和一种每穗颖花数预测方法进行探讨,研究这些方法在高产栽培中的应用。
Rice yield is spike number per unit area, spikelet number per spike, seed setting rate and grain weight of four factors. In order to predict the yield and test the correctness of each cultivation measure, it is necessary to understand the formation process of each component and make a prediction. This experiment is based on the early and late rice high-yielding experimental plots cultivated by our farmer teacher Liu Zhicong, and the test of several spike number prediction methods and one method of spikelet number per spike were carried out to study the effects of these methods in high-yielding cultivation application.
