近年来,随着耕作制度的变化和小麦立体高效栽培模式的推广,使晚播麦的面积逐年扩大。如何对晚播麦进行科学管理,提高其产量,成为目前急需解决的问题。为此,我们根据本地实际,对晚播麦高产栽培技术进行了深入研究,总结出以“大播量保穗数,前期控分蘖调群体,重管拔节期增粒重”为核心的晚播麦高产栽培技术体系,经示范,效果十分明显。1995年在我市示范推广80万亩,平均亩产达到358.4公斤,比对照田平均亩增产43.7公斤,增产率13.9%。其中亩产400公斤以上的面积达到24万亩,占示范区总面积的30%,取得了显著的经济效益。其栽培要有以下几个方面:
In recent years, with the change of farming system and the promotion of three-dimensional and efficient cultivation mode of wheat, the area of late sowing wheat has been expanded year by year. How to conduct scientific management on late sowing wheat and increase its output has become an urgent problem to be solved. To this end, we conducted an in-depth study on the late-sowing high-yielding cultivation techniques of late-sowing wheat according to the local conditions and concluded that the core of "high-yielding sowing dates, pre-tillering and tillering population, Late sowing high-yielding cultivation technology system, after demonstration, the effect is very obvious. In 1995, 80 million mu of land was popularized in our city, with an average mu yield of 358.4 kilograms, an increase of 43.7 kilograms compared with the average mu in the control field and an increase rate of 13.9%. The area of more than 400 kg per mu reached 24 million mu, accounting for 30% of the total area of the demonstration area and achieved significant economic benefits. The cultivation has the following aspects:
