Abstract
The invention relates to a cultivation technology for vegetation, in particular to a method for planting Suaeda salsa and other halophytes in the dry and windy desert saline and alkaline soil. The method comprises the following steps: the seeds of Suaeda salsa or other salt tolerant plants are planted in any desert saline and alkaline soil ditched in the specific direction in September to November, so that the seeds are prevented from being blown away by wind, the required moisture for seed germinating in spring can be ensured by fully utilizing the snowfall during the winter; and the specific direction of ditching is the direction perpendicular to the wind direction during the sowing. By adopting the method, the negative influence of the strong wind and dry weather to the planting of the Suaeda salsa and the other halophytes is overcome, the Suaeda salsa and the other halophytes can be planted in the extremely arid high saline and alkaline soil at inland on a large scale, the vegetation is established, the bare alkaline deserts, the diffusion of the salinization and the aaline-alkaline dust storm thereof can be eliminated, and the improvement and the optimization of the ecological environment can be realized.
Description
Technical field
The present invention relates to the culture technique of vegetation, a kind of specifically in arid and the fluffy method of gale desert saline environment plantation alkali.
Background technology
Because causing saline and alkaline dust of desert saline environment and saline and alkaline dust storm to wreak havoc, shortage vegetation, arid and strong wind cause disaster severe water and soil erosion, the salination of peripheral arable land is corroded in the salination diffusion, and consequently not even a blade of grass grows for the crops trees withered or died, form the pollution of desertification and water source, air, the harm human and livestock health.
Therefore wait halophytes on exposed saline and alkaline desert, to set up vegetation by plantation alkali is fluffy, eliminate the environmental hazard that saline and alkaline desert is brought, to the change NORTHWEST CHINA, northeast, the ecotope of wide geographic areas such as North China has crucial meaning.
Chinese patent application number is the artificial cultivation method of setting forth wild suaeda glauce in 97106197.1, this method relates to the artificial cultivation that carries out seepweed plant in the saline land, but its agricultural use that is mainly used in saline-alkali environment is a main purpose with products such as harvested vegetable oil plants, though also can be used for the Vegetation Construction of desert environment, but there is following shortcoming in the technical measures of being taked such as management of sowing in adverse circumstances wholely: 1, its type of seeding in the inland arid saline and alkaline desert because wind is big, seed is easily blown away by wind, influences the foundation of vegetation; 2, She Ji sowing time landlocked just saline and alkaline desert zone especially the arid season, the rainfall rareness can't be irrigated again, influences seed germination; Therefore all influence the growth of seed.
Summary of the invention
The object of the present invention is to provide a kind of method that can in arid and gale desert saline environment, plant fluffy or other halophytes of alkali.
For achieving the above object, the technical solution used in the present invention is:
Kind of method for planting: fluffy or other salt-tolerant plant seed makes its seed avoid being blown away and making full use of by wind the snowfall in winter and guarantees that seed sprouts required moisture the beginning of spring in any desert saline environment that is planted in the 9-11 month by the specific direction trench digging with alkali; Described specific trench digging direction is and the perpendicular direction of when sowing wind direction.
Described trench digging is meant the direction trench digging vertical with wind direction, and described ditch shape can be " ∠ " type shallow ridges, and ditch depth 3-15 centimetre, furrow width 4-15 centimetre, ditch is apart from 20-50 centimetre.Described trench digging is preferably ditch depth 7-9 centimetre, and furrow width 8-10 centimetre, ditch is apart from 30 centimetres.Fluffy or other salt-tolerant plant of described alkali can be sowed after the production of hybrid seeds, production of hybrid seeds process is: per 1000 gram seeds and 1000-2000 gram agar-agars or the water-soluble liquid phase of algin are mixed, then seed is placed loess dry powder to be stirred to into to sieve behind the particle that to go unnecessary loess to dry standby.Mark meter by weight, the described agar-agar or the algin aqueous solution are: agar-agar or marine alga rubber powder add in 100 parts of water for 1 part, boil be cooled to after the thawing 40-20 ℃ standby; Described loess dry powder is 40-60 order fine earth.The seed of described other salt-tolerant plant is Chinese tamarisk, salt wormwood artemisia, salicornia europaeal, alkali thatch, sacsaoul or salsola collina.The described sowing time is preferably October.
The advantage that the present invention had:
1, designed opening the method for seed furrow with the perpendicular direction of wind direction, can prevent that wind from washing away seed.Especially ∠ type ditch seed is broadcast in this ditch acute angle, can not blown away by wind, but be adjacent to better effects if with the bottom.Vertically open seed furrow and not only can prevent that wind from washing away seed but also can utilize the fine earth that is blown up to cover seed, strengthened the heat insulating ability of seed.
2, the present invention selects to sow the 9-11 month the designed sowing time, made full use of that arid area snowfall in winter covers and in seed furrow, store the snowfall in winter as the beginning of spring after the required moisture of seedling germination and growth, guarantee that making seed obtain enough moisture after the beginning of spring, snow-broth melted sprouts smoothly, this has just solved the difficult problem of the rare influence sowing of arid area rainfall.
If 3 take related producing method for seed, then more increased the moisture capacity and the weight of seed, make seed not only be difficult for being blown away by wind but also can from environment, absorbing moisture.
4, can take the mechanization sowing because of this method,, form the scale ecological benefits rapidly so be particularly suitable for setting up the fluffy grade of alkali halophytes vegetation on a large scale in the vast Desert Area of area.Can be widely used in construction of saline and alkaline Desert Area large-scale ecological and environmental greening.
