1 选地与整地1.1 选地高丹草对土壤要求不太严格,除盐碱地、涝洼地和酸性较强的土壤不宜种植外,一般耕地均可种植。但因其生物产量高、地力消耗大,宜选择土壤肥力较好或前茬为豆类地块。高丹草的生产潜力大,产量受灌溉条件的影响很大,高丹草强调刈割后浇水和生育后期浇水,这与大田粮食作物的浇水时间不同,因而选择离井近的地段既有利于生产又有利于节水。夏秋季节青饲利用随用随割,因而选择离公路、饲养场所近的地段,省工、省时,种草养畜生产高效。从轮割
An election and site preparation 1.1 The election of Dan dan grass requirements of the soil is not too strict, in addition to saline-alkali land, waterlogging depression and acid soil is not suitable for planting, the general cultivation of arable land. However, due to its high biological yield and high geo-consumption, the soil fertility should be better or the former crop should be plots of legumes. The production potential of sudangrass is large and the yield is greatly influenced by the irrigation conditions. The sudangrass emphasizes the watering after the cutting and the later watering, which is different from the watering time of the field grain crops. Therefore, Not only conducive to production but also conducive to water conservation. Summer and autumn use of green catches with the use of cut, so choose from the road, near breeding sites, labor-saving, time-saving, high efficiency livestock production. Cut from the wheel
