为了掌握淮南稻区小麦高产规律,我们在小麦生长过程到一些小麦高产单位进行了调查,结合前两年的调查资料,对淮南稻区小麦亩产500—700斤高产稳产栽培经验,做了初步总结。一、创造合理的高产群体结构,是夺取小麦高产稳产的中心环节小麦高产的形成,是穗数、粒数、粒重协调发展的结果。前者决定于群体,后两者决定于群体影响下的个体。群体大小是由基本苗数和分蘖成穗所决定。群体与个体既矛盾又统一。我们在小麦高产栽培
In order to grasp the law of high yield of wheat in Huainan rice area, we conducted some surveys on some high-yielding wheat units during wheat growth. Combining with the survey data of the previous two years, we made preliminary preliminary research on the high-yield and stable yield cultivation of 500-700 kg of wheat per mu in Huainan rice area to sum up. First, to create a rational high-yield population structure is to capture the high-yielding wheat in the central part of the formation of high-yield wheat is the spike number, grain number, grain weight and coordinated development. The former is determined by the group, the latter two are determined by the group under the influence of individuals. Population size is determined by the number of basic seedlings and tillers into ears. Both groups and individuals are contradictory and united. We are in high-yielding wheat
