Embodiment 1

[0025] The method for improving grassland No. 3 miscellaneous alfalfa quality by mowing adopts the following steps:

[0026] (1) Site selection and preparation:

[0027] Choose a site with flat terrain and a soil layer thickness of more than 30cm, and turn the ground before planting to make the ground flat, the soil clods finely divided, and no weeds;

[0028] (2) Sowing:

[0029] The sowing method of single sowing is selected. The grass seed of single sowing is Grassland No. 3 grass seed. The sowing rate is 7.5-15kg / mu. Sowing is carried out at the end of May and early June. After covering the soil, suppress it again, so that the soil and the seeds are in close contact, which is conducive to the germination of the seeds;

[0030] (3) Field management:

[0031] Apply diammonium phosphate after sowing, and the fertilizer rate is 80kg / hm 2 , irrigate once after sowing, in order to protect the seedlings from growing vigorously and avoid weed erosion, weeding was carried out i...

Embodiment 2

[0036] The method for improving grassland No. 3 miscellaneous alfalfa quality by mowing adopts the following steps:

[0037] (1) Site selection and preparation:

[0038] Choose a site with flat terrain and a soil layer thickness of more than 30cm, and turn the ground before planting to make the ground flat, the soil clods finely divided, and no weeds;

[0039] (2) Sowing:

[0040] The sowing method of single sowing is selected. The grass seed of single sowing is Grassland No. 3 grass seed. The sowing rate is 7.5-15kg / mu. Sowing is carried out at the end of May and early June. After covering the soil, suppress it again, so that the soil and the seeds are in close contact, which is conducive to the germination of the seeds;

[0041] (3) Field management:

[0042] Apply diammonium phosphate after sowing, and the fertilizer rate is 80kg / hm 2 , irrigate once after sowing, in order to protect the seedlings from growing vigorously and avoid weed erosion, weeding was carried out i...

Embodiment 3

[0047] The method for improving grassland No. 3 miscellaneous alfalfa quality by mowing adopts the following steps:

[0048] (1) Site selection and preparation:

[0049] Choose a site with flat terrain and a soil layer thickness of more than 30cm, and turn the ground before planting to make the ground flat, the soil clods finely divided, and no weeds;

[0050] (2) Sowing:

[0051] The sowing method of single sowing is selected. The grass seed for single sowing is Grassland No. 3 grass seed. The sowing rate is 7.5-15kg / mu. It is sown at the end of May and the beginning of June. After covering the soil, suppress it again, so that the soil and the seeds are in close contact, which is conducive to the germination of the seeds;

[0052] (3) Field management:

[0053] Apply diammonium phosphate after sowing, and the fertilizer rate is 80kg / hm 2 , irrigate once after sowing, in order to protect the seedlings from growing vigorously and avoid weed erosion, weeding was carried out ...

Abstract

The invention relates to the technical field of agricultural plantation and in particular discloses a method of improving quality of CaoYuan No.3 Medicago varia martyn via clipping. The method of improving quality of CaoYuan No.3 Medicago varia martyn via clipping comprises the following steps of (1) selecting and preparing a land, (2) sowing, choosing a clean-culturing way, (3) managing the field and (4) clipping. The beneficial effects are that after the clipping, contents of crude protein and ash in the herbage can be improved; nutritive value is enhanced; and crude fiber content is reduced; and palatability is improved.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of agricultural planting, in particular to a method for improving the quality of grassland No. 3 alfalfa by mowing. [0003] (2) Background technology [0004] Alfalfa is the leguminous forage with the longest cultivation history and the highest economic value in my country. Grassland No. 3 is a perennial herb bred from Grassland No. 2 hybrid alfalfa. It has strong cold resistance and drought resistance, high growth rate and good quality. It is an excellent new alfalfa variety. It is artificially grown in northern my country. Plays an important role in the establishment of grasslands. Based on its excellent production characteristics, improving the quality of Grassland No. 3 is actually related to the production and life of herdsmen. [0005] Among various forage efficient utilization strategies, mowing is a common and effective method. Moderate mowing can cause direct damage to the aboveground p...
