Embodiment 1
[0026] Embodiment 1 A kind of spring planting method of Horqin sandy alfalfa
[0027] Alfalfa planting requires flat land, loose soil, good water and air permeability, no weeds, and suitable soil moisture. The pointer sprinkler can irrigate and fertilize at the right time, and there are mechanical equipment such as sprayers to spray at the right time herbicide.
[0028] The alfalfa seed was selected from the Cavalier T variety produced in Canada, and its coating weight accounted for 33%; the grass companion plant was selected from oats, and its seeds were selected from domestic common seeds.
[0029] The specific steps of the Horqin sandy land alfalfa planting method in spring of the present embodiment are as follows:
[0030] (1) Before sowing oats, the companion plant of Gramineae, the plot should be plowed deeply, and then harrowed to ensure that the soil particles are fine and the permeability is good.
[0031] Specifically, the deep plowing depth is 25-30cm, and the gro...

Abstract
The invention discloses a spring planting method for medicago sativa in Horqin sandy land. The method comprises the following steps: screening gramineous associated plants, firstly planting the screened gramineous associated plants in late March to early April, spraying a chemical herbicide when the associated plants grow to a tillering stage, and sowing the medicago sativa after overground partsof the associated plants are withered, yellow and dead. The spring planting method disclosed by the invention utilizes stubble of the associated plants as a natural barrier of seed germination, seedling emergence and seedling growth of the medicago sativa, and the stubble can not only protect soil moisture, but also avoid the problems of a low survival rate of the spring medicago sativa caused bysand wind encroachment, and promote germination of the medicago sativa and growth of seedlings; the associated plants are sown in the early stage, so that inhibition of growth of weeds is facilitated,and the chemical herbicide is sprayed, so that the associated plants can be prevented from continuing to grow to generate inhibition on the germination and growth of the medicago sativa, and the method has significant effects; and the medicago sativa is planted in May, so that a yield of hay and economic benefits in a current year can be improved, roots have sufficient time to be developed afterthe medicago sativa is sown, the overground parts of the medicago sativa can improve an overwintering rate after cutting is performed, and the operability is high.
Description
technical field [0001] The invention relates to the technical field of pasture planting, and more specifically, relates to a spring planting method of alfalfa in Horqin sandy land. Background technique [0002] Alfalfa is a perennial leguminous forage with high protein content and rich nutrients. It is known as the "king of forage" because of its strong growth adaptability and high hay yield. In northern China, alfalfa can be mowed 3-4 crops per year, and the hay yield can reach 600-1000kg / mu. With the introduction of policies such as revitalizing the dairy industry in my country, the planting area of alfalfa will be further expanded. It is estimated that by 2020, the total area of alfalfa planting in the country will reach 6 million mu. [0003] The Horqin Sandy Land starts from Shuangliao County, Jilin Province in the east, and ends in Wengniute Banner, Chifeng City, Inner Mongolia in the west. The north and south are between the loess hills in the northern part of Ya...
