Embodiment 1

[0023] Sweet sorghum "Hercules" and multiflora ryegrass "Extra High" in rotation. Sow the annual sweet sorghum "Hercules" in mid-to-late March, wait for it to grow to 1.5-2.0m, and use it for the first mowing, leaving about 10cm of stubble, and topdressing 1-2 days after mowing, about 3-4 weeks , used for the second mowing, and then mowing once every 3 to 4 weeks, until the end of September, a total of 4 to 5 times, and then plowing the field, and sowing annual multi-flowered ryegrass from late September to early October "Te Gao" was mowed every 3 to 4 weeks during the period, and a total of 4 to 5 times were mowed during the growth period. The annual sweet sorghum "Hercules" was planted after the stubble was stubbled from late March to early April of the following year. After it is used up, the leguminous forage alfalfa "Suntory" is planted after the stubble is stubbled in the middle and late September, and the crop rotation is repeated in this way.

Embodiment 2

[0025] Sweet sorghum "Hercules" and alfalfa "Suntory" crop rotation. Sow the annual sweet sorghum "Hercules" from late March to early April, wait for it to grow to 1.5-2.0m, cut and use it for the first time, leave a stubble of about 10cm, and topdress 1-2 days after cutting, about 3-2 4 weeks, the second mowing is used, and then mowing once every 3 to 4 weeks, until the end of September, a total of 4 to 5 times, and then the field is plowed, and leguminous forage is sown from late September to early October Alfalfa "Suntory" is cut every 3 to 4 weeks during the period, and a total of 3 to 4 times during the growth period, and the annual sweet sorghum "Hercules" is planted after the stubble is used up from late March to early April of the next year. ", to the middle and late September, and then sow the annual multiflora ryegrass "Extra High" after stubble, and carry out crop rotation in this way.

Abstract

The invention relates to a rotation method of warm-season forage grass in hilly red soil region, especially for annual warm-season forage grass Sorghum Bicolar (L.). The method alternately plants Sorghum Bicolar (L.) and annual cold-season gramineous forage grass or perennial leguminous forage grass, to fully utilize limited land, maximally produce high-quality forage grass for feeding herbivorous animals, and achieve whole year balanced supply of forage grass to improve breeding benefit. The method provided by the invention reasonably combines warm-season forage grass with cold-season forage grass, improves traditional farming system in southern hilly red soil region, greatly improves land utilization rate, increases breeding benefit of herbivorous animals, and has broad application prospect and feasibility.

Description

technical field [0001] The invention relates to a crop rotation planting method of warm-season herbage in the southern hilly red soil area, in particular to a crop rotation planting method of the annual warm-season pasture sweet sorghum "Hercules". Background technique [0002] High-quality forage is the material basis for the development of animal husbandry, and plays a decisive role in improving the ecological environment, maintaining ecological balance, and protecting human survival and development. However, the high-quality forage in the hilly red soil area of ​​my country is relatively scarce, and there are disadvantages such as unbalanced supply of forage and single nutrition, which cannot meet the nutritional needs of herbivores for balanced forage, which seriously affects the rapid development of herbivorous animal husbandry. At present, summer grasses such as perennial "hybrid pennisetum" wither in late autumn and early winter, and the land will be abandoned in the ...
