The Cultivative Technology of Intercropping Cotton and Potato

对棉花与马铃薯间套作的提高土地利用率、充分利用光、热资源以及蚜虫、棉铃虫危害情况进行了具体分析，认为实行间套作后利大于弊，两者有互补作用；提出了棉薯间套作在栽培管理上必须掌握好５个关键技术，方能取得理想效果。通过１９９２～１９９６年大面积生产示范，每６６６．７ｍ２籽棉可产２００～２５０ｋｇ，马铃薯可产１５００ｋｇ。

The concrete analysis had been made according to specific circumstances of intercrpping cotton and potato,it may make good use of the land,light,heat and the demage were also made by aphid and blooworm.The intercropping cotton and potato should master the technolohy of cultivation and management,then,it can achieve ideal result.The large area production edmonstration were carried out from 1992～1996,the results showde that the yield of unginned cotton was 3 000～3 750 kg/hm2,the potato was 22 500 kg/m2 and the average per unit area may increase 2 000～2 500 RMB$.
