Abstract
After the crops, Chinese medicinal herbs, shrub and arbor are sowed or cuttage grafted on the deteroirated grassland desert and desertified land the liquid mulch film raw juice is mixed with 4-12 times clear water, and uniformly sprayed on the above-mentioned desertified land, said liquid mulch film possesses strong coherent action, and can make soil form agglomeration body so as to can prevent wind erosion and water erosion, and can increase soil temp. by 1-4 deg.C, and its evaporation inhibiting rate is above 30%, and its water content can be raised by above 20%, so that it can culture well-growing vegetation so as to attain the goal of controlling sand and fixing film.
Description
Technical field
A kind of method of in administering the desertification of land engineering, utilizing the liquid mulch film ontrolling sand and fixing desert.
Background technology
The soil desert influences the development of local economy, is the common issue that faces in the environmental protection of countries in the world.
China's land deterioration, 2100 square kilometres in newly-increased every year on average desertification soil has a strong impact on and restricts further developing of Chinese national economy.
Administer the soil desert in the past and mainly adopted conventional methods such as kind of a grass, tree planting.Conventional method is relatively poor because of its defensive ability/resistance ability, and the entry-into-force time is slow, can not satisfy improvement speed and effect of requirement.
Summary of the invention
The objective of the invention is to utilize the method for spraying liquid mulch film, administer the soil of desert, the soil in desertification is is just prevented and treated, make it satisfy the requirement of the regulation effect and the speed of improvement.
The liquid mulch film that the present invention uses reaches the development of high-tech development Co., Ltd by Beijing is plump, and obtains Ministry of Agriculture's " agricultural fertilizer faces word 218 " number interim licenses.
Activities of the present invention is as follows: after carrying out crops, herbal medicine, shrub, arbor sowing or cuttage on the soil of desert, degeneration grassland, desertification, desertification, liquid mulch film Normal juice is blended into 4-12 times of clear water, use common spray pattern, every mu of ground evenly sprays liquid mulch film Normal juice 40-100 kilogram.
After using liquid mulch film, because of it has strong adhesive attraction, Gu Er can make the soil after the sprinkling, is tied, form comparatively ideal aggregate, thereby prevent the generation of water erosion and wind erosion phenomenon, and can make soil temperature raising 1-4 ℃, the evaporation inhibiting rate is more than 30%, the water content increase rate increases more than 10% greater than 20% water-stable granule, thus, can nurture well-grown vegetation, thereby reach the purpose of the solid film of sand control.
After using liquid mulch film, do not need artificial rupture of membrane, plant seedlings is rupture of membranes and going out directly, and mulch film can be degraded automatically, can soil not polluted, and improvement soil desert efficient height, speed is fast, and epochmaking social benefit and economic benefit are arranged.
The specific embodiment
Liquid mulch film Normal juice is blended into 5 times of clear water, pack in the large-scale sprinkling jar, spraying jar is placed on the special-purpose frame of establishing behind the farm tractor, in spraying jar, force (forcing) pump is set, pressurization is sprayed, and shower nozzle is a seedpod of the lotus head, and the weep hole diameter is 2mm, evenly be sprayed on the desertification soil, every mu is sprayed 50 kilograms of liquid mulch film Normal juice.
Claims (1)
- A kind of method of in administering the desertification of land engineering, utilizing the liquid mulch film ontrolling sand and fixing desert.It is characterized in that: after carrying out crops, herbal medicine, shrub, arbor sowing or cuttage on the soil of desert, degeneration grassland, desertification, desertification, liquid mulch film Normal juice is blended into 4-12 times of clear water, use common spray pattern, every mu of ground evenly sprays liquid mulch film Normal juice 40-100 kilogram.
