赣州地区地少、劳多,近年来,稻田多熟制发展很快,其中以稻稻油三熟复种方式占居主导地位,其面积已达20万亩以上。这一复种方式的发展,对提高粮油产量,增加农民收益,都发挥了极为重要的作用。但这种复种制本身也带有一定的局限性,主要是耕地用养关系还不够协调,油菜接茬季节紧张,用工多,成本大,经济效益不够理想。因此,改进复种方式,达到粮油三熟高产、低耗、高收益的目的,是进一步发展粮油三熟栽培的新课题。
In Ganzhou, there is less land and more labors. In recent years, there has been a rapid development of multi-cropping systems in paddy fields. Among them, the rice-rice oil occupies the leading position in the double-cropping system with the area of more than 200,000 mu. The development of this multiple cropping system has played an extremely important role in raising grain and oil output and increasing farmers’ income. However, this kind of compounding system itself also has some limitations. The main reason is that the relationship between arable land and landownership is still not enough coordination. The rapeseed stubble season is tense, the labor cost is large, the cost is not ideal enough. Therefore, improving the method of multiple cropping and achieving the goal of high yield, low consumption and high yield of three crops of grain and oil is a new task to further develop the three-crop cultivation of grain and oil.
