苏北沿海地区不同盐渍程度的土壤上选用相应的牧草品种,采取一年生与多年生、豆科与禾本科相结合,四季牧草搭配,割青利用与青贮利用相配合等措施,可以作到青饲料常年均衡供应。同时还应抓好整地播种、合理密植,实行混播和加强肥水管理等技术措施,以争取较高的产量。秋播牧草的供草期主要集中在4—6月和9—11月二个时期,苏丹草等主要在夏秋季利用,冬季则主要是胡萝卜及部分青贮饲料。改土培肥,建立相应的种植模式:在轻盐土上实行四季牧草轮种或和粮、棉、油作物间套种;在含盐中等的土壤上种植耐盐牧草,边改良,边利用;重盐土则先以双季绿肥改良,然后发展牧草生产。
The selection of the corresponding forage species on soils with different salinities in the coastal areas of northern Jiangsu Province can be accomplished by adopting perennials of annuals and perennials, combination of legumes and grasses, combination of forage with four seasons, combination of cut green utilization and silage utilization, Balanced supply. At the same time, we should also do a good job of land preparation and sowing, reasonable and close planting, implementation of mixed broadcasting and enhancement of fertilizer and water management and other technical measures so as to strive for higher output. Autumn grazing grass supply mainly concentrated in the April-June and September-November two periods, Sudan grass and other main use in summer and autumn, winter is mainly carrot and some silage. Soil improvement and fertilization, the establishment of the corresponding planting mode: the implementation of four seasons in light salt soil rotation of crops or intercropping with grain, cotton, oil crops; Salt tolerance in the cultivation of salt-tolerant grass, while improving, while the use of heavy Salt soil is the first double green manure improved, and then develop pasture production.
