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後山冷涼乾旱地區開發種植甜菜的情況及地膜覆蓋栽培技術等措施。
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. 地膜覆蓋無孔種植法，用地膜平鋪於表土，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，莊稼增產不比傳統覆蓋法少。
