这种新技术是,秋季在准备种植西红柿的地里播种野豌豆,长到来年春季割倒,留茬约三厘米高,不需整地,不进行任何处理,紧接着马上栽植西红柿苗。短时间内,可能很难从割倒的野豌豆中分辨出西红柿,但仅几天后,割倒的野豌豆便干枯了,形成一层褐色的地面覆盖物。这层覆盖物可抑制早期杂草的生长,而且栽植西红柿前还可不施用除草剂。

The new technology is to sow the wild peas in the autumn in preparation for the planting of tomatoes, cut to length by the spring of next year, stubble about three centimeters high, without soil preparation, without any treatment, and immediately planted tomato seedlings. In a short time, it may be difficult to distinguish tomatoes from cut-off wild peas, but after a few days the cut-off peas dried up to form a brown ground cover. This layer of cover can inhibit the growth of early weeds, but also without the application of herbicides before planting tomatoes.
