What kind of pasture can I grow after harvesting wheat and raising fish? What kind of pasture can I grow when ryegrass is exhausted? Preferred Sudan grass, Sudan grass is a kind of adaptable, high yield forage and long, summer and autumn grass supply period is long, palatability, protein and amino acid content, both its growth and nutrition are very in line with fish feeding, and fish digestibility is high, is a high-quality green feed for fish.
First, Sudan grass characteristics: Sudan grass annual herb, leaves are thin, regenerative, tillering ability, warm-loving, not cold-tolerant, drought resistance, the strongest heat resistance, can make full use of the pond slope. The land next to the road can be planted, the soil requirements are not strict, and the general land can be planted, but it is not suitable for planting on swampy soil and quicksand.
Second, Sudan grass harvesting times and yield: Sudan grass to water and fertilizer response is good, in order to obtain high yield, to fertilize and irrigate it to achieve the ideal output value, after entering the tillering period, the whole fertility process rapid tillering, growth rate accelerated, a day and night growth of 5-10cm, planting for about 40 days can feed fish, harvesting at a plant height of 90-120 cm, can be harvested 4-6 times a year, the entire growth period yield is as high as about 8 tons, After harvesting, timely watering and topdressing fertilizer can be harvested again in about 20 days.
Third, Sudan grass planting: Sudan grass is generally planted in spring, before planting to choose a suitable local climate, in the spring night temperature is stable above 10 degrees to the beginning of summer can be sown, in the selection of seeds, must choose full seeds, bright color, high-quality seeds, so as to good germination to achieve high yield. Before sowing in advance, apply the bottom fertilizer in an appropriate amount, so that the land becomes fertile, it is recommended to use the sowing method of strip sowing, 4 pounds of seeds per acre, the seeds are evenly sprinkled in the land, the row spacing can be 30 cm, the sowing depth is 2-3 cm, and the soil is covered with 2 cm. Then gently press the soil and water the land at the right time.
Fourth, field management: Sudan grass in the plant height of about 120 cm for harvesting and fish farming, after harvesting stubble height in 3-4 cm, Sudan grass loves water, after harvest to timely fertilization and watering to promote its growth, in addition, during the growth period for its good growth, must prevent the occurrence of diseases, regularly carry out disease control and weeding and other work. Some weeds will appear during the growth process and need to be removed in time, you can manually weed or use professional herbicides for weeding.
5. Nutritional value: Sudan grass is rich in crude protein, crude fat, crude fiber and nitrogen-free extract, of which crude protein content can reach 14%, crude fat in 2%, crude fiber in 3%, is a high nutritional value of forage, grass texture is tender, palatability is good, can greatly improve the feed rate of fish, but also a good helper for breeding cattle and sheep, improve breeding efficiency.
