Embodiment 1

[0028] The method for establishing alfalfa grassland in cold regions, using the grass species as Golden Queen, includes the following steps:

[0029] 1) Preparation for sowing: select the stubble field 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 furrow depth of 10cm, and a seeding rate of 37.5kg / hm 2 , the sowing depth is about 2cm, cover with soil a little, and rake the whole field before winter, which is equivalent to covering the alfalfa with soil before winter, so that the root neck of alfalfa can go deep into the ground to reduce freezing damage;

[0031] 3) Plant establishment management: the temperature is low in spring, the seedlings grow very slowly in the year of sowing, and frost falls when they reach the branching stage or budding stage, weeds are removed at alfalfa plant heights of about 10 cm, and decomposed animal manure...

Embodiment 2

[0035] The planting method of alfalfa meadow in cold region, the grass seed is Giant 201 alfalfa, including the following steps:

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

[0037] 2) Alfalfa sowing: sow alfalfa in the first ten days of May, the sowing row spacing is 40cm, the sowing furrow depth is 15cm, and the sowing rate is 45kg / hm 2 , the sowing depth is about 2cm, cover with soil a little, and rake the whole field before winter, which is equivalent to covering the alfalfa with soil before winter, so that the root neck of alfalfa can go deep into the ground to reduce freezing damage;

[0038] 3) Plant establishment management: the temperature is low in spring, the seedlings grow very slowly in the year of sowing, and frost falls when they reach the branching stage or budding stage, weeds are removed at alfalfa plant heights of about 10 cm, and decompos...

Embodiment 3

[0042] The method for establishing and planting alfalfa grassland in cold regions, using the grass seed Gannong No. 1 alfalfa, includes 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, cover with soil a little, and rake the whole field before winter, which is equivalent to covering the alfalfa with soil before winter, so that the root neck of alfalfa can go deep into the ground to reduce freezing damage;

[0045] 3) Plant establishment management: the temperature is low in spring, the seedlings grow very slowly in the year of sowing, and frost falls when they reach the branching stage or budding stage, weeds are removed at alfalfa plant heights of about 10 cm, and de...

Abstract

The invention discloses a method for establishing alfalfa grasslands at cold regions, comprising the following steps of: seeding preparation: namely selecting stub land of which the preceding stubs oat or highland barley or rape are closely planted crops, ploughing and harrowing soil, manuring barnyard manure, and weeding; selecting alfalfa varieties such as gold queen, Algonquin, Alfaking, Juren201 and Gannong 1 which have strong cold resisting ability; alfalfa seeding, namely seeding in early May, 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, the seeding depth is about 2 centimeters and the thickness of soil cover is about 2cm; establishing management, namely weeding when the height of alfalfa plants is about 10 centimeters and then watering and manuring the barnyard manure or a phosphaticfertilizer; grassland mowing, namely mowing in early October in the first year, and moving the first stubs in middle July during bud stage or initial bloom stage in which stubble height is about 5cm, and the second stubs in late September at full-bloom stage in which the stubble height is 7-8cm in the 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 method, 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 atthe cold regions are solved.

Description

technical field [0001] The invention relates to planting alfalfa, in particular to a method 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 Grass" for its high yield, excellent grass quality, and the advantages of livestock and poultry. The suitable area for alfalfa planting 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 pests, ...
