近年来,育苗移栽棉在全国主要棉区迅速推广。江苏省1983年已扩展到744万亩,占全省总棉田面积的60%以上,有力地促进了棉花生产的发展。但随着棉田复种指数的提高,茬口和前茬配置方式的改变,棉田生态环境日趋恶化,严重地影响了育苗移栽优势的发挥。因此,如何改善棉田生态环境,发挥移栽棉的优势,是当前值得研究的一个重要课题。现据我们的研究结果和大面积生产考察,综合报道如下。
In recent years, transplanting cotton seedlings in the country’s main cotton area quickly promoted. Jiangsu Province in 1983 has been extended to 744 million mu, accounting for more than 60% of the province’s total cotton field area, effectively promoted the development of cotton production. However, with the improvement of cotton multiple cropping index, the change of arrangement of stubble and stubble, the ecological environment of cotton is deteriorating day by day, which has seriously affected the advantages of seedling transplanting. Therefore, how to improve the ecological environment of cotton field and give full play to the advantages of transplanting cotton is an important issue worth studying at present. According to our research results and large-scale production inspection, comprehensive report is as follows.
