目前农业生产上刚刚推广应用低密度线型地膜(简称线型膜)覆盖棉花、花生、蔬菜、水稻等农作物,有人认为只起降低成本作用,无增产效果。对此,1985年我们采用线型膜覆盖1403亩花生试验,结果不仅有降低亩成本作用,而且还有显著地增产效果,无论是大面积覆盖或小区对比试验,结果一致。现就线型膜 At present, agricultural production has just promoted the use of low-density linear film (referred to as linear film) covering cotton, peanuts, vegetables, rice and other crops, some people think only to reduce costs, no stimulation effect. In this regard, in 1985 we used 1403 acres of linear membrane covering peanut test results not only reduce the cost of mu, but also significantly increased yield, whether large-area coverage or cell contrast test, the results are consistent. Now on the linear membrane
