近年来,由于风障材料短缺价高,越冬菠菜因无风障保护设施,往往在冬雪少风大的情况下造成大量死苗,减产减收,甚至有种无收。群众种越冬菠菜积极性不高,播种面积逐年减少,菠菜成了短缺品种。本试验力图通过在越冬期采取塑料薄膜地面复盖取代风障的设想,以求达到安全越冬,提高保苗率为主要目的,促进早熟早上市,增产增收。八二年在全市五个公社十一个生产队安排了108.5亩试验、示范面积。从去冬今春对基点队的调查情况看,基本上达到了预期试验目的。
In recent years, due to the shortage of wind barrier materials, winter spinach due to wind-free barrier protection facilities tend to cause a large number of dead seedlings in the winter snow less wind, reduce production, or even no crop. The enthusiasm of the masses for overwintering spinach is not high, and the sown area has been decreasing year by year. Spinach has become a shortage of varieties. In this experiment, we try to replace the wind barrier with the plastic film in the winter to replace the wind barrier, in order to achieve the safe winter, improve the seedling rate as the main purpose, to promote early morning market, increase production. In 1982, 108.5 mu of trial and demonstration area were arranged in eleven production teams of five communes in the city. According to the investigation of the base team from last winter and spring, the purpose of the intended test is basically reached.
