Problems solved by technology

[0002] Black soil is an important natural resource in our country and plays a pivotal role in my country's agricultural development. However, unreasonable plowing and planting methods have been adopted for a long time, water and soil conservation and repeated rolling of agricultural machinery and equipment have been ignored, resulting in thinning and hardening of black soil. Decreased organic matter content, resulting in degradation of black soil resources

Embodiment 1

[0031] A method for mixed seeding of oats and alfalfa in black soil, comprising the following steps:

[0032] (1) Land consolidation

[0033] The black soil is plowed to a depth of 20cm, and the plowed black soil is leveled and watered once, and the water soaking depth is 30cm;

[0034] (2) Seed pretreatment

[0035] After oat and alfalfa seeds are mixed evenly according to the weight ratio of 100:20, then mixed evenly with the seed treatment agent, the consumption of the seed treatment agent is 10 times of the total weight of the oat and alfalfa seeds, and the seed treatment agent consists of 20 parts of slow release Fertilizer, prepared by mixing 10 parts of antibacterial and insecticide, 2 parts of straw powder, and 30 parts of black earth soil;

[0036] (3) Sowing

[0037] Adopt the drill method to sow, the sowing distance is 25cm, the sowing depth is 6cm, and the sowing rate is 5kg / mu. After the sowing is completed, water after covering 2cm to ensure that the soil humi...

Embodiment 2

[0044] A method for mixed seeding of oats and alfalfa in black soil, comprising the following steps:

[0045] (1) Land consolidation

[0046] The black soil is plowed to a depth of 30cm, and the plowed black soil is leveled and watered once, and the water soaking depth is 40cm;

[0047] (2) Seed pretreatment

[0048] After the oat and alfalfa seeds are mixed evenly according to the weight ratio of 200:20, they are evenly mixed with the seed treatment agent. The amount of the seed treatment agent is 8 times the total weight of the oat and alfalfa seeds. The seed treatment agent consists of 15 parts of slow release Fertilizer, prepared by mixing 10 parts of antibacterial and insecticide, 5 parts of straw powder, and 50 parts of black earth soil;

[0049] (3) Sowing

[0050] Adopt the drill method to sow, the sowing distance is 15cm, the sowing depth is 4cm, and the sowing rate is 5kg / mu. After the sowing is completed, water after covering 1cm of soil to ensure that the soil h...

Embodiment 3

[0058] A method for mixed seeding of oats and alfalfa in black soil, comprising the following steps:

[0059] (1) Land consolidation

[0060] The black soil is plowed to a depth of 25cm, and the plowed black soil is leveled and watered once, and the water soaking depth is 25cm;

[0061] (2) Seed pretreatment

[0062]After the oat and alfalfa seeds are mixed evenly according to the weight ratio of 150:20, they are evenly mixed with the seed treatment agent, and the amount of the seed treatment agent is 9 times the total weight of the oat and alfalfa seeds, and the seed treatment agent consists of 15 parts of slow release Fertilizer, prepared by mixing 8 parts of antibacterial and insecticide, 4 parts of straw powder, and 40 parts of black earth soil;

[0063] (3) Sowing

Abstract

The invention provides a mixed sowing method for oats and alfalfa according to the ecological environment and the soil condition of the black land. The yield and the quality of the oats and the alfalfa are improved, the acre yield of hay can reach 550 kg, and the crude protein yield can reach 27 kg; meanwhile, the soil quality and the ecological environment of the black land can be improved based on the growth of the oats and the alfalfa; and meanwhile, a specific seed treatment agent is selected, so that the relatively high germination rate and good drilling uniformity of the seeds can be ensured, and the problem of non-uniform seeding caused by small grain sizes of the oat and alfalfa seeds is solved.

Description

technical field [0001] The invention belongs to the technical field of forage planting, in particular to a method for mixed sowing of oats and alfalfa in black soil. Background technique [0002] Black soil is an important natural resource in our country and plays a pivotal role in my country's agricultural development. However, unreasonable plowing and planting methods have been adopted for a long time, water and soil conservation and repeated rolling of agricultural machinery and equipment have been ignored, resulting in thinning and hardening of black soil. The content of organic matter decreases, resulting in the degradation of black soil resources. Therefore, it is urgent to take effective measures to develop black soil resources rationally and improve the soil quality of black soil. [0003] Among them, forage mixed sowing refers to the planting method in which two or more forage species of different species and biological groups are mixed and sown on the same field at...
