Embodiment 1

[0028] The planting technology of alfalfa grassland in cold regions, the selection of grass species is Golden Queen, including the following steps:

[0029] 1) Preparation for sowing: select the stubble land where the previous stubble is oats, plow the soil, apply decomposed livestock manure, and weed removal;

[0030] 2) Alfalfa sowing: Sow alfalfa in early May, with a row spacing of 30cm, a sowing furrow depth of 10cm, and a seeding rate of 37.5kg / hm 2 , the sowing depth is about 2cm, the thickness of the soil is about 2cm, and the whole land is raked before the soil freezes, which is equivalent to resoiling alfalfa before winter, so that the root neck of alfalfa can go deep into the ground to reduce freezing damage;

[0031] 3) Planting management: The temperature in spring is low, the seedlings grow very slowly in the year of sowing, and the frost will fall when they reach the branching stage or budding stage. Weeds should be removed when the plant height of the alfalfa is...

Embodiment 2

[0035] The planting technology of alfalfa grassland in cold regions, the grass species is Giant 201 alfalfa, including the following steps:

[0036] 1) Preparation for sowing: select the stubble land where the previous stubble is oats, plow the soil, apply decomposed livestock manure, and weed removal;

[0037] 2) Alfalfa sowing: sow alfalfa in early May, with a row spacing of 40cm, a sowing furrow depth of 15cm, and a seeding rate of 45kg / hm 2 , the sowing depth is about 2cm, the thickness of the soil is about 2cm, and the whole land is raked before the soil freezes, which is equivalent to resoiling alfalfa before winter, so that the root neck of alfalfa can go deep into the ground to reduce freezing damage;

[0038] 3) Planting management: The temperature in spring is low, the seedlings grow very slowly in the year of sowing, and the frost will fall when they reach the branching stage or budding stage. Weeds should be removed when the plant height of the alfalfa is about 10c...

Embodiment 3

[0042] The planting technology of alfalfa grassland in cold regions, the grass species is Gannong No. 1 alfalfa, including the following steps:

[0043] 1) Preparation for sowing: select the stubble field where the previous stubble is barley, plow the soil, apply decomposed livestock manure, and weed removal;

[0044] 2) Alfalfa sowing: in early May, sow alfalfa with a row spacing of 35cm, a sowing furrow depth of 12cm, and a sowing rate of 40kg / hm 2 , the sowing depth is about 2cm, the thickness of the soil is about 2cm, and the whole land is raked before the soil freezes, which is equivalent to resoiling alfalfa before winter, so that the root neck of alfalfa can go deep into the ground to reduce freezing damage;

[0045] 3) Planting management: The temperature in spring is low, the seedlings grow very slowly in the year of sowing, and the frost will fall when they reach the branching stage or budding stage. Weeds should be removed when the plant height of the alfalfa is abo...

Abstract

The invention discloses technology for establishing alfalfa grasslands at cold regions. The technology comprises the following steps of: seeding preparation, namely selecting stub land of which the preceding stubs are closely planted crops, ploughing and harrowing soil, manuring barnyard manure, and weeding; alfalfa seeding, namely seeding in early May, backfilling shallow soil, and raking the soil smooth before being frozen, wherein the seeding row spacing is 30 to 40 centimeters; the seeding ditch depth is 10 to 15 centimeters; the seeding quantity is 37.5 to 45kg per hectometer; and the seeding depth is about 2 centimeters; establishing management, namely weeding when the height of alfalfa plants is about 10 centimeters and then watering and manuring the barnyard manure or a phosphatic fertilizer; grassland mowing, namely mowing in early October in the first year, and moving the first stubs in middle July and the second stubs in late September in next year; and winter irrigation, namely performing winter irrigation before the soil is frozen. By selecting cold-resistant alfalfa varieties and suitable cold-resistant planting technology, the alfalfa can smoothly live through a first winter and spring, the aim of establishing the alfalfa grasslands at the cold regions is fulfilled, and the problems of leguminous forage deficiency and nutritional imbalance of domestic animals at the cold regions are solved.

Description

technical field [0001] The invention relates to planting alfalfa, in particular to a technique for establishing and planting alfalfa in cold regions. Background technique [0002] There is a lack of leguminous forage in alpine pastoral areas, and the nutrition of livestock is unbalanced. The main reason for this phenomenon is that there are few species of leguminous forages suitable for cultivation on the one hand, and the lack of planting technology for leguminous artificial grasslands on the other hand. Alfalfa in the leguminous family is known as the "King of Forage" for its high yield, excellent grass quality, and the advantages of livestock and poultry. The suitable area for alfalfa plantation is the temperate climate zone, and there are many varieties of alfalfa suitable for planting. Grassland planting is easy to succeed, and the key points of cultivation technology are mainly to select high-yield and high-quality varieties that are resistant to diseases and insect p...
