A high-efficiency planting model of forage grass with three harvests and three harvests a year in the Huanghuaihai Plain

Abstract

The present invention relates to a high-efficiency planting mode of forage grass with three harvests and three crops a year in the Huang-Huai-Hai Plain. The following forage grass species are selected to establish the following planting system: 1. Hairy vetch mixed sowing composition. (2) The planting system is: forage barley is sown in the early spring with ditches and ditches; after the forage barley is harvested, the forage millet is followed by no-tillage drill; , Arrowhead pea mixed sowing according to the seed weight 1:1 ratio for mixed sowing. The method is as follows: the first step, planting and harvesting barley for forage; the second step, planting and harvesting millet for forage; The invention realizes three kinds of forage grasses and three harvests a year in the Huanghuaihai Plain region, which strongly supports the high-quality development of herbivorous animal husbandry in this region for the demand for high-quality forage grass and increases farmers' income, and has important applications for the high-quality development of my country's agriculture and animal husbandry value.

Description

technical field [0001] The invention relates to a high-efficiency forage grass planting mode, specifically a high-efficiency planting mode of forage grass with three harvests and three harvests a year in the Huanghuai-Hai Plain. Background technique [0002] The Huang-Huai-Hai Plain is one of the areas with the highest degree of agricultural and animal husbandry intensification in my country. There are more people and more animals than land, and the contradiction between people, land, grass and animals is prominent. At the same time, the area of ​​medium and low-yielding fields in this area is large, and it is urgent to establish a new planting system to realize the combination of cultivated land use and nutrition and continuous improvement and fertilization. With the in-depth advancement of my country's supply-side structural reform and the implementation of the strategy of storing grain locally, the grass-fed animal husbandry with dairy cows, beef cattle and mutton sheep a...

Problems solved by technology

The traditional forage planting mode in this region is mainly silage corn-winter wheat is cropped twice a year, silage corn-forage rye is cropped twice a year, and perennial alfalfa. Due to the low total forage production, it is currently unable to meet the needs of grass-fed livestock in this region. Poultry’s demand for high-quality forage has resulted in the overall production level of grass-fed livestock and poultry still hovering at a moderate level; at the same time, the traditional planting patterns of silage corn-winter wheat and silage corn-fodder rye are not Conducive to the combination of cultivated land use and nutrition and improved fertilization
