根据多年观测研究结果：小麦播种出苗最适宜的耕层土壤含水量为18％～22％。小麦出苗所需最低含水量：粘土地为IROA＿170／be土地15％～16％，沙土地为14％，低于这个标准小麦播后不能出苗，应抗旱造墒。抗旱种麦群众习惯先造墒后播种。在9月下旬或10月初，这样做是正确的。已
According to the results of many years of observational research, the optimum moisture content of topsoil is 18% ~ 22%. The minimum water content required for emergence of wheat: Clay IROA_170 / be 15% ~ 16% of the land, sandy land 14%, below this standard can not be sprouted after sowing wheat, drought should be entropy. Drought drought planted masses used to sow moisture after sowing. In late September or early October, this is correct. Already
