冬小麦产量是由每亩穗数、每穗粒数和籽粒千粒重三大要素所构成。在当前农业生产水平情况下,小麦产量在很大程度上受气象条件所支配。一九八二至一九八三年度冬小麦生育期间农业气象条件如何?对小麦产量的形成有何利弊?现根据安徽省小麦主产区代表县的气象资料和有关调查、考种材料,从大范围上加以分析。一、秋播期和冬前苗期水热条件适宜,利于播种、出苗和盘根分蘖安徽省小麦主要产区的宿县、阜阳两地 The winter wheat yield is composed of three elements: spike per acre, grain number per spike and grain weight per acreage. At current levels of agricultural production, wheat production is largely governed by meteorological conditions. What are the agricultural meteorological conditions during the growth of winter wheat in 1982-1983? What are the pros and cons of the formation of wheat yield? Based on the meteorological data of the representative counties in the major wheat producing areas in Anhui Province and the relevant survey and examination materials, Range to be analyzed. First, the autumn sowing period and pre-winter seedling suitable for hydrothermal conditions, which will help sowing, emergence and packing tillers The main producing areas in Anhui Province Suxian County, Fuyang, two places
