摘要
在作物品种不断出新,栽培技术不断革新、农业机械化水平不断提高等现代农业体系条件下,发展多样化的绿肥种植利用模式,采取因地制宜、见缝插针、有空就种、用养结合的原则,既可解决黄淮海地区多熟高产与肥料不足的矛盾,又有利于耕作制度的创新和科学种田水平的提升。根据黄淮海地区的自然条件与特点,适宜绿肥种植模式有中高肥力区二粮二肥、二粮一肥;中低肥力区棉肥轮作、棉肥间作;盐碱地区二肥一粮、肥饲兼用等模式。
In the modem agriculture system with new plant cultivars, creative cultivation technique and advanced farm machines, developing diversified green manure planting model both resolves the contradiction between high field and the fertilize defect and inno- vates ＇the farming system and improves the planting technique level. According to the climatic condition and soil fertility of Huang - Huai - Hal plain, the suitable green manure planting model is two crops with two green manure or two crops with one green manure in the high soil fertility fields. The rotation and intercropping between cotton and green manure in the low soil fertility fields and two green manure with one crop, green manure used both as fertilize and feed in the saline - alkali soil fields.
