Problems solved by technology

[0005] Monoculture ryegrass has the following three disadvantages: 1. Although ryegrass can be planted in the south to obtain higher yields, it cannot fully meet the needs of livestock for nutrients because it is mainly carbohydrates and has a protein content of 4.93%. ; 2. More protein concentrates need to be added, which will reduce the cost of breeding and is not conducive to the development of grain-saving animal husbandry; 3. Ryegrass is a nitrogen-consuming pasture. Long-term planting will lead to poor soil and even reduce subsequent crop yields. Fertilizer needs to be applied after mowing, which is easy to cause environmental pollution

Abstract

A ryegrass and legume mixing sowing method includes (1), cleaning ground sundries before sowing, turning up the soil and applying base fertilizers after leveling the soil; (2), sowing the ryegrass and the legume in a mixing manner; (3), planting and cutting; (4), cutting the ryegrass first in the early stage of the growing period; and (5), reserving stubbles with height of 50cm after cutting peas in production so as to guarantee regeneration conditions of the peas. Problems of fresh grass underproduction in withered grass periods in animal husbandry or nutritive value unbalance of single-sowing of the ryegrass can be well solved by utilizing southern winter vacant fields.

Description

technical field [0001] The invention relates to the technical field of pasture cultivation, in particular to a method for mixed seeding of ryegrass and leguminous pasture. Background technique [0002] 1. Current situation of pasture planting in winter [0003] Southern my country is located in the subtropical zone, which is a warm and humid climate. Due to the high humidity throughout the year, a large amount of forage produced in summer cannot be effectively dried and stored. In addition, the production of fresh grass during the dry grass period in winter is insufficient, resulting in a shortage of forage in winter, which restricts southern my country. The development of animal husbandry. It is an important content in the development of animal husbandry to study high-yield and high-quality pasture suitable for planting in winter. Ryegrass has become the main cultivated variety of annual artificial grassland in southern China, and the cultivated area is gradually expanding...
