巴盟河套灌区由于土壤次生盐渍化严重耕作栽培措施不当,同时对农业气候资源趋利逊害不够,致亩产量长期徘徊在200斤上下。为了确切掌握灌区小麦粒重在产量构成中的作用,我们通过查阅杭锦后旗1956—1979年小麦单产和千粒重的有关资料(见表一),认为凡是小麦单产高的年份千粒重也高,单产低的年份千粒重也低,其相关系数为0.71。群众说:丰收年景每麻袋小麦净重220—230斤,每百斤小麦能出头等白面80—90
Due to the improper tillage and cultivation measures of secondary salinization in Bameng Hetao Irrigation District, it is not enough to promote the aggravating of climate resources in agriculture. As a result, the output per mu has long been hovering around 200 kg. In order to know exactly the role of grain weight per unit area of grain yield in the irrigation area, we obtained information about the yield and grain weight of wheat in Hangqinhou Banner from 1956 to 1979 (Table 1), and found that those with high single-crop yields had higher thousand-grain weight and lower yield Thousand grain weight is also low, the correlation coefficient of 0.71. The masses said: bumper harvest every sack wheat net weight 220-230 pounds, per kilogram of wheat can be the first white flour 80-90
