Embodiment 1

[0022] An improved method for mixed sowing of grassland in saline-alkali land, comprising the steps of:

[0023] 1) Grassland division: Select suitable grassland for improvement, divide it into multiple plots according to 4m×3m, and the interval between each plot is 40cm, then build supports in the interval areas, and erect drip irrigation pipes above the supports.

[0024] 2) Seed treatment: first sort the seeds, divide them into Gramineae and Leguminosae, add the Gramineae seeds into the seed treatment agent and soak for 30 minutes, and then spray 6% alkali spray liquid for spraying treatment; The seeds are treated with onion concentrate for 10 minutes, and then coated with dimethyl sulfoxide and antifreeze; the seed treatment agent consists of the following raw materials in parts by weight: 5 parts of paclobutrazol, 3 parts of pentaerythritol, nucleotide water 3 parts, 0.8 parts of dodecyl dimethyl betaine, 50 parts of water; the mass ratio of the dimethyl sulfoxide to the ...

Embodiment 2

[0028] An improved method for mixed sowing of grassland in saline-alkali land, comprising the steps of:

[0029] 1) Grassland division: Select a grassland suitable for improvement, divide it into multiple plots according to 5m×3m, and the interval between each plot is 45cm, and then build supports in the interval areas, and erect drip irrigation pipes above the supports.

[0030] 2) Seed treatment: first sort the seeds, divide them into Gramineae seeds and Leguminosae seeds, add Gramineae seeds into the seed treatment agent and soak for 35 minutes, and then spray 7% alkali spray liquid for spraying treatment; The leguminous seeds were treated with onion concentrate for 12 minutes, and then coated with dimethyl sulfoxide and antifreeze; the seed treatment agent was composed of the following raw materials in parts by weight: 8 parts of paclobutrazol, 5 parts of pentaerythritol, nucleotide 4 parts of water, 1 part of lauryl dimethyl betaine, 55 parts of water; the mass ratio of d...

Embodiment 3

[0033] An improved method for mixed sowing of grassland in saline-alkali land, comprising the steps of:

[0034] 1) Grassland division: Select suitable grassland for improvement, divide it into multiple plots according to 6m×4m, and the interval between each plot is 50cm, then build supports in the interval areas, and erect drip irrigation pipes above the supports.

[0035] 2) Seed treatment: the seeds are first sorted, divided into two types of large seeds and small seeds, the large seeds are added to the seed treatment agent and soaked for 40 minutes, and then sprayed with 8% alkali spray solution; the small seeds are Treat with onion concentrate for 15 minutes, and then use dimethyl sulfoxide and antifreeze to coat; the seed treatment agent consists of the following raw materials in parts by weight: 10 parts of paclobutrazol, 7 parts of pentaerythritol, and 6 parts of nucleotide water , 1.2 parts of dodecyl dimethyl betaine, 60 parts of water; the mass ratio of dimethyl sul...

Abstract

The invention discloses an improvement method for mixed sowing of saline-alkali grassland and belongs to the technical field of crop cultivation. The invention realizes the improvement of mixed sowing of grassland in saline-alkali land through three steps of grassland division, seed treatment and mixed sowing planting. The invention divides the grassland into multiple areas, performs classification and mixed sowing, improves the utilization rate of seeds, and installs drip irrigation pipes above the brackets built in the interval areas, which ensures the water demand requirements of crops, and can improve the yield and quality of mixed sowing pastures . The present invention treats gramineous and leguminous forage seeds separately, and selects different coordinate positions in different planting areas, thereby improving soil, reducing weed invasion, and significantly improving alkalization degree. The emergence rate of the alfalfa in the invention is 93.7%-94.2%, the quality of emergence is healthy, and the 30-day survival rate is 94.6%-96.7%. The output of the mixed sowing grassland of the invention is increased by 50.93% to 58.20%, wherein the output of tall fescue is increased by 48.17% to 51.59%, and the economic benefit is remarkable.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to an improvement method for mixed sowing of grassland in saline-alkali land. Background technique [0002] Saline-alkali land is a type of soil salt accumulation. Excessive salt in the soil will affect the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants can hardly survive in severe saline-alkali soil areas. [0003] Mixed sowing grassland is an artificial grassland where two or more pasture grasses are cultivated on the same piece of land. Countries with developed animal husbandry in the world often use mixed sowi...
