近几年来,郊区利用棉田宽行套播油菜秧逐年增多。但由于耕作及管理上的矛盾较多,难以育成壮秧标准,影响油菜高产。为此,我们从1980～1982年,采用“早密矮”的棉花栽培技术,3月25日育苗,麦后移栽,每亩约七千株。7月15日前打顶心,株高控制在60cm以下,留果枝7～8个。9月上、中旬,喷800ppm乙烯利催熟。这样,10月1日前收花基本结束,平均亩产皮棉113.2～122.2斤。随即播种油菜,秧龄四十天左右,11月10日前后移栽时,就能达到壮苗标准(见表)。
In recent years, the suburban use of broad-rowed cotton seedling rapeseed increased year by year. However, due to more contradictions in farming and management, it is difficult to breed strong seedling standards and affect rapeseed yield. To this end, we from 1980 to 1982, the use of “early morning and short” cotton cultivation techniques, March 25 nursery, wheat transplanting, about 7000 per acre. July 15 Top Top Center, plant height control below 60cm, leaving fruiting branches 7 to 8. September, mid, spray 800ppm ethephon ripening. In this way, before October 1 close the end of the average income of lint 113.2 ~ 122.2 kg per mu. Then sowing rapeseed, seedling age about 40 days, November 10 before and after transplanting, you can achieve strong seedling standard (see table).
