二元组合覆盖玉米是用地膜和秸秆两种材料组合的一种全覆盖模式,它将地膜覆盖的增温保墒和秸秆覆盖的降温保墒有机地结合起来,减少了秸秆前期降温和地膜后期增温的弊端,具有明显的土壤环境效应和生物学效应,有效地改善了土壤生态条件,调控了玉米的生长发育进程和地上部与地下部的协调生长,提高了玉米对氮磷钾的吸收和干物质积累与灌浆强度,是解决黄土高原残塬沟壑区水土流失的一项措施。
Binary combination of corn is a combination of plastic film and straw two kinds of full coverage mode, which will cover the plastic film mulching and soil moisture conservation and soil temperature and soil conservation organically combine to reduce the straw pre-cooling and post-filming temperature Which has obvious soil environmental effects and biological effects, effectively improves the soil ecological conditions, regulates the growth and development of maize and the coordinated growth of above-ground and underground parts, and increases the absorption and dryness of the maize to nitrogen, phosphorus and potassium Material accumulation and grouting intensity are a measure to solve the soil and water loss in the gully area on the loess plateau in the Loess Plateau.
