Embodiment 1

[0010] The ecological protection cultivation method of asparagus in the desertification area is realized by the following steps: a, select the purple passion variety to raise seedlings on the plug substrate; b, carry out trenching and planting, the depth of trenching is 25cm, no fertilizer is applied, and the planting density is 1000 plants / mu, The depth of planting is 20cm; c. Water once on the day of planting, on the third day, and on the seventh day, and leave grass to maintain the ground coverage; d. Always keep 6 female stems when harvesting.

[0011] Compared with the blank plot, the wind speed is reduced by 22%, the surface roughness is significantly increased, and the sand-resistance effect is 0.7, which has a better wind-proof and sand-fixing effect.

Embodiment 2

[0013] The ecological protection cultivation method of asparagus in the desertification area is realized by the following steps: a. Select the champion variety to grow seedlings on the plug substrate; b. Dig trenches for planting. The depth is 15cm; c. Water once on the day of planting, on the third day, and on the seventh day, and leave small grass to maintain the ground coverage; d. Always keep 4 female stems when harvesting.

[0014] Compared with the blank plot, the wind speed is reduced by 18%, the surface roughness is significantly increased, and the sand-resistance effect is 0.6, which has a good wind-proof and sand-fixing effect.

Embodiment 3

[0016] The ecological protection cultivation method of asparagus in the desertification area is realized by the following steps: a, select the Jinggang 701 variety to raise seedlings in plug trays; b, carry out trenching and planting, the depth of trenching is 21cm, no fertilizer is applied, and the planting density is 950 plants / mu. The depth of planting is 19cm; c. Water once on the day of planting, on the third day, and on the seventh day, and leave small grass to maintain the ground coverage; d. Always keep 5 female stems when harvesting.

[0017] Compared with the blank plot, the wind speed is reduced by 21%, the surface roughness is significantly increased, and the sand-resistance effect is 0.63, which has a good wind-proof and sand-fixing effect.

[0018] In the specific implementation process, the selection of asparagus varieties is the result of comparative experiments of 8 varieties. 8 varieties (Purple Passion, Dabaoli, Holy Knight, Jinggang 701, Grande, Champion, G...

Abstract

The invention particularly relates to an ecological protection and cultivation method for desertification area asparagus. The ecological protection and cultivation method for the desertification area asparagus solves the problems that the prior mechanical sand-protecting barrier and biological sand fixation are poor in control effect, long in period, high in cost and poor in economic performance. The ecological protection and cultivation method for the desertification area asparagus is achieved according to the following steps that a, Purple Passion, Champion and Jinggang 701 varieties are selected and are used for raising seedlings in a plug substrate mode; b, ditching and colonization are conducted, the ditching depths are 20-25cm, fertilizer is not applied, the colonization density is 800-1000 plants / mu, the colonization depths are 15-20cm; c, the day when colonization is conducted, and two days later and six days later after colonization is conducted, the asparagus is watered once respectively, and small grass is left to keep a grass coverage rate on the ground; d, when the asparagus is harvested, 4-6 mother stems are always kept. The ecological protection and cultivation method for the desertification area asparagus plays a good role in preventing wind and fixing sand, capable of greatly shortening the period of wind preventing and sand fixing when being compared with plantation of shrub species, and capable of generating better economic benefits, increasing income of local peasants, and ensuring that wind speed reduces by 18-22% and the sand blocking function is 0.6-0.7.

Description

technical field [0001] The invention relates to a cultivation method in a desertification area, in particular to an ecological protection cultivation method for asparagus in a desertification area. Background technique [0002] Soil desertification refers to the process of turning good soil or usable land into sandy soil or land or even desert. The main processes of soil desertification are wind erosion and wind accumulation. In the surrounding areas of the desert, due to vegetation destruction or grassland overgrazing or reclamation into farmland, the soil becomes dry due to dehydration, soil particles are scattered, eroded by wind, and the content of fine particles decreases. After the wind has passed or weakened, the wind-blown sand particles gradually accumulate on the soil surface to make the soil sandy. Therefore, soil desertification includes the process of wind erosion of grassland soil and the process of wind-sand accumulation in remote areas. [0003] my country...
