晚播小麦地膜覆盖栽培,是小麦生产上一种新兴的保护性栽培技术。同小麦露地栽培一样,覆盖栽培也应有其适宜的播期和最晚播种时间。根据多年的试验研究,地膜覆盖栽培小麦的适宜播期为霜降至立冬,只要播种后栽培措施得当,也能取得适时麦的产量。为了探讨地膜覆盖小麦的晚播极限和生育特点及栽培技术,于1987～1989年连续两年度进行了试验研究。
Late-sowing wheat film mulching cultivation, wheat production is a new protective cultivation techniques. As with the open field cultivation of wheat, the covering cultivation should also have its suitable sowing date and the latest sowing time. According to years of experimental study, the suitable seeding date of mulched film mulched wheat is frost drop to wintering. As long as planting measures after sowing are proper, the yield of timely mulch can also be obtained. In order to investigate the late-sowing limit and reproductive characteristics and cultivation techniques of mulching wheat, the experiment was conducted in two consecutive years from 1987 to 1989.
