水稻—小麦连作是里下河地区主要的种植方式。近年来,随着农村商品经济的发展,传统的纯粮生产已不再适应农户的要求,因此在保证农田主产业的基础上,如何通过立体开发来增加农田收入,是生产上迫切需要解决的问题。前些年,各地对稻田种养技术研究不少,但对麦田立体种植还缺乏系统研究。1985～1988年,我们对稻茬小麦田间作的产量、经济效益及主要技术指标进行了探索,现将结果整理如下,供生产上参考应用。
Rice-wheat continuous cropping is the main planting method in the Lixiahe area. In recent years, with the development of rural commodity economy, the traditional pure grain production no longer meets the requirements of farmers. Therefore, on the basis of guaranteeing the main industries of farmland, how to increase the farmland income through the three-dimensional development is an urgent need to be solved in production problem. A few years ago, there were many researches on the cultivation techniques of paddy fields in various places, but there was no systematic study on the three-dimensional cultivation of wheat fields. From 1985 to 1988, we conducted exploration on the yield, economic benefits and main technical indexes of the wheat crop in rice stubble. The results are summarized as follows for reference.
