Development of planting sugarbeet and covering film techniques were introduced in the cold and drought area of Urad Front Banner in the Inner Mongolia. 介紹了內蒙古烏拉特前旗后山冷涼干旱地區開(kāi)發(fā)種植甜菜的情況及地膜覆蓋栽培技術(shù)等措施。
In contrast, the imperforate film mulching method is a way to cover the topsoil with the film fixed by compacted soil on its ends when the crop is planted beside the film. 地膜覆蓋無(wú)孔種植法，用地膜平鋪于表土，邊沿用土壓緊封閉，將莊稼種在地膜旁邊，膜下土壤中的水分和熱量不易散失，卻容易吸收外界水分，因此，莊稼增產(chǎn)不比傳統覆蓋法少。
