晚播麦出苗迟,发根差,分蘖慢,结果往往是穗头少,穗型小,粒重低,严重影响平衡增产。分析原因,固然与客观上的茬口晚、季节紧和稻板地的粘、湿、僵有关,但只要充分发挥人的积极因素,做好矛盾的转化工作,克服不利因素,使之向“三早”(早出苗、早发根、早发棵)方面发展,也是完全可能的。 Late sowing late emergence of wheat, hairy roots, tillers slow, the results tend to be less panicle, panicle type, low weight, seriously affecting the balance of production. Analysis of the reasons, of course, late with the objective crop, the season tight and the sticky rice, wet, stiff related, but as long as give full play to the positive factors, good contradictory transformation work to overcome unfavorable factors, to make “ Three early ”(early emergence, early root, early tree) is also possible.
