Efficient forage grass planting mode for three-planting and three-harvesting in one year in Huang-Huai-Hai plain

Abstract

The invention relates to an efficient forage grass planting mode for three-planting and three-harvesting in a year in the Huang-Huai-Hai plain. The following forage grass variety is selected, and thefollowing planting system is established: 1, the forage grass variety is formed by mixed sowing and combination of forage barley, forage millet, common vetch and hairy vetch; and (2) the planting system is as follows: ditching and drill sowing are performed on the forage barley in early spring, stubble-connecting no-tillage drill sowing is performed on the forage millet after the forage barley isharvested, and stubble-connecting no-tillage mixed sowing is performed on the hairy vetch and the common vetch after the forage millet is harvested; and the hairy vetch and the common vetch are subjected to mixed sowing according to the seed weight ratio of 1: 1. A method comprises the following steps of 1, planting and harvesting the forage barley; 2, planting and harvesting the forage millet; 3,performing mixed sowing, planting and harvesting on the hairy vetch and the common vetch. Forage grass can be planted for three times and harvested for three times in a year in the Huang-Huai-Hai plain areas, the requirement of high-quality development of herbivorous animal husbandry in the areas for high-quality forage grass and the income increase of farmers are powerfully supported, and the mode has important application value for high-quality development of agriculture and animal husbandry in China.

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
