Embodiment 1

[0020] A kind of pasture mixed plantation management method in saline-alkali land, comprises the following steps:

[0021] A. Dig drainage ditches every 1050 meters; dig a branch ditch every 320 meters; dig a furrow every 45 meters; water the ditches or rain water to promote the salt in the soil to penetrate with the water Deep soil, reducing the salinity in the plow layer, thereby reducing the salinity of the soil;

[0022] B. Use 50kg / mu of superphosphate and 150kg / mu of cattle and sheep manure as the base fertilizer, evenly sprinkle the fertilizer into the ground before plowing, and then plow into the soil;

[0023] C. Soak the seeds of alfalfa and sandawang for 2.5 minutes before sowing;

[0024] D, plant alfalfa and Satawang at the density of plant spacing 5-7cm×row spacing 5-7cm, for the convenience of cutting, alfalfa and Satawang are planted at intervals;

[0025] E. After the forage emerges, weeding and thinning shall be carried out in time; and topdressing shall be...

Embodiment 2

[0032] A kind of pasture mixed plantation management method in saline-alkali land, comprises the following steps:

[0033] A. Dig drainage ditches every 1100 meters; dig a branch ditch every 350 meters; dig a furrow every 40 meters; irrigate the ditch with water or rain to promote the salt in the soil to penetrate into the Deep soil, reducing the salinity in the plow layer, thereby reducing the salinity of the soil;

[0034] B. Use 55kg / mu superphosphate and 135kg / mu cattle and sheep manure as the base fertilizer, evenly sprinkle the fertilizer into the ground before plowing, and then plow into the soil;

[0035] C. Soak the seeds of alfalfa and sandawang for 3 minutes before sowing;

[0036] D, plant alfalfa and Satawang at the density of plant spacing 5-7cm×row spacing 5-7cm, for the convenience of cutting, alfalfa and Satawang are planted at intervals;

[0037] E. After the forage emerges, weeding and thinning shall be carried out in time; and topdressing shall be carried...

Embodiment 3

[0044] A kind of pasture mixed plantation management method in saline-alkali land, comprises the following steps:

[0045] A. Dig drainage ditches every 900 meters; dig a branch ditch every 250 meters; dig a hair ditch every 50 meters; water the ditches or rain water to promote the salt in the soil to penetrate with the water Deep soil, reducing the salinity in the plow layer, thereby reducing the salinity of the soil;

[0046] B. Use 40kg / mu of superphosphate and 175kg / mu of cattle and sheep manure as the base fertilizer, evenly sprinkle the fertilizer into the ground before plowing, and then plow into the soil;

[0047] C. Soak the seeds of alfalfa and sandawang for 2 minutes before sowing;

[0048] D, plant alfalfa and Satawang at the density of plant spacing 5-7cm×row spacing 5-7cm, for the convenience of cutting, alfalfa and Satawang are planted at intervals;

[0049] E. After the forage emerges, weeding and thinning shall be carried out in time; and topdressing shall b...

Abstract

The invention discloses a management method for mixed planting of pasture forage in saline-alkali land. The management method comprises the following steps that ditches are dug and water is poured soas to reduce the salt content of soil; superphosphate and cattle-sheep manure are used as a base fertilizer, the fertilizer is evenly spread into the ground before ploughing, and then a plough is usedto turning over the fertilizer into the soil; seeds of alfalfa and astragalus adsurgens pall are soaked before sowing; the alfalfa and astragalus adsurgens pall are planted at intervals; weeding andthinning are carried out in time after the forage emerges; topdressing is carried out; and watering is carried out after mowing, and a modifier is added. The management method for mixed planting of pasture forage in saline-alkali land can significantly reduce the salt content of the saline-alkali field, and the yield of forages is significantly increased due to the use of special soaking liquid and the modifier.

Description

technical field [0001] The invention relates to the technical field of forage planting, in particular to a management method for mixed planting of pasture in saline-alkali land. Background technique [0002] The fundamental reason for the formation of saline-alkali soil is poor moisture status, so in the early stage of improvement, the focus should be on improving the soil moisture status. Generally, it is carried out in several steps. First, drain and wash salt to reduce the salinity content of the soil; then plant salt-resistant plants to fertilize the soil; finally plant crops. The specific improvement measures are: drainage, irrigation and salt washing, silt improvement, rice planting, fertilizer improvement, land leveling and chemical improvement. [0003] At present, there are few domestic researches on grass fertilizers, especially the research on grass planting in saline-alkali land is seldom reported. The company builds a modern agricultural park on the saline-alk...
