苏丹草是当前季节草食性鱼(主要是草鱼、鳊鱼)的主要青饲料。如何提高苏丹草的产量和质量,对提高草食性鱼的产量和提高苏丹草的利用率关系重大,在目前已成苗的情况下。适时,正确地刹割和科学地管理是提高苏丹草产量和质量的关键。一、刹割技术: 1、开割草的高度:第一批于50～70厘米开割,以后则达100～120厘米。由于第一批草的生长时间较长,草的纤维含量较高,为提高草的利用率和不影响下批草的生长,故第一批短点割。 2、刹割时留茬高度:第一批留高10厘米,第二批7厘米,第三批8厘米,第四批7厘米……,总原则是长短交替。这样,既
Sudan grass is the main green feed for herbivorous fish (mainly grass carp, anchovy) of the current season. How to improve the yield and quality of sudangrass is very important for improving the yield of herbivorous fish and increasing the utilization rate of sudangrass. Proper and proper cutting and scientific management are the keys to increasing Sudan’s grass yield and quality. First, brake cutting technology: 1, open mowing height: The first batch of 50 ~ 70 cm cut, then up to 100 ~ 120 cm. As the first batch of grass grow longer, grass fiber content is higher, in order to improve grass utilization and does not affect the growth of the next batch of grass, so the first batch of short cut. 2, when the stubble stubble height: the first batch of stay 10 cm high, the second batch of 7 cm, the third batch of 8 cm, the fourth batch of 7 cm ... ... The general principle is the length of the alternating. In this way, both
