The construction method of sandy land vegetation recovery
Affiliated technical field
The present invention relates to the kind method for planting of a kind of suitable desertification desertification soil plant, in order to the revegetation of sandy land.
Background technology
Learn with the experience of soil desertification struggle for many years according to people, although do not have Shaoshi fertilizer when Turf Culture or forest and after the plantation, water less, but because soil property moisture capacity, nutrient preserving capability are all very poor, seedling promptly can not get sufficient nutriment in a fertilizer and guarantees, again less than the water conservation of local soil with release water function and support, as if 1 year seedling is pretty good often, and generally die young after two, three years.At present to desertification desertification soil plant planting, generally all adopt adding suction Water fixing agent to improve the lack of water soil environment, as people such as Ge Xuegui (' environmental mineral, SAP, the pre-test of Chemical Sandy Fixation Slurry Material comprehensive regulation desert ', " petromineralogy magazine ", calendar year 2001,12) adopt SAP (Super absorben polgmer) super absorbent resin, pillared montmorillonite lacks aluminium type zeolite; CN1343754 adopts bentonite and zeolite; Yet these materials can only temporarily improve water shortage status, and some also can cause second environmental pollution.CN1078343 passes through system paper pulp with stalk in addition, Ensure Liquid liquid, make paper tape at last, in the middle of two-layer paper tape, play seed, directly paper tape is tiled in the soil during sowing and gets final product: CN1509598 is pressed into the plate from plant wastes that contains the required nutrient of plant growing with waste material of stalk and agro-product processing etc., can be used for the seed germination on lawn etc.; Though these technology have solved no-tillage and problem seed germination, yet it has ignored transformation and extensive use of chemical fertilizer to soil environment, is unfavorable for that the plant of being planted continues to survive chronically and grow.Therefore, how guaranteeing under the normal prerequisite of growing up of seedling, building a kind of moisture capacity in seedlings root, local soil environment that nutrient preserving capability is good is the active demand of desertificationization in the world wide.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of and can carry out plant planting desertification desertification soil, can carry out solid water, solid fertilizer, getting fat, improve soil fertility sandy land again simultaneously, the sandy land vegetation recovery construction method of excellent support condition is provided for the late growing stage of plant.
The present invention realizes by following technical measures: at first the stalk material is woven into the straw rope that diameter is 10~30mm, and before construction 5~10 days with concentration be the water-soluble rubbish strain liquid of 7PMM soak at normal temperatures take out after 1~2 hour standby; And then the powder of straw that the stalk that will be difficult for weaving straw rope is made into Φ 1~5mm is mixed and made into the powder of straw that contains barnyard manure mutually with barnyard manure, its mixing ratio by weight, powder of straw: barnyard manure is 2: 1; To contain again afterwards barnyard manure powder of straw, spirulina, that cellular phyllosilicate sand control new material is mixed and made into the stalk compound mutually is standby, its mixing ratio by weight, the powder of straw that contains barnyard manure: spirulina: cellular phyllosilicate sand control new material is 0.18~0.38: 0.035~0.04: 1, wherein said cellular phyllosilicate sand control new material is that the patent No. is 03135646x, publication number be CN1487053 disclosed " cellular layer silicate sand control new material ".Adopt earlier artificial during construction or mechanical means is left ditch on sandy land, and the standby straw rope that soaked through the rubbish strain liquid inserted in the ditch, then by weight, plant seed: the stalk compound is that 0.01~0.05: 1 ratio is mixed plant seed with the stalk compound, straw rope in the ditch in ditch, rewaters their dispensers then, earthing gets final product.
The used stalk of the present invention is that agricultural goes up the agricultural byproducts stalk material that easily produces environmental pollution, and this stalk and barnyard manure, biological inoculum biodegrade produce humus, increase soil fertility; Powder of straw is evenly mixed with cellular phyllosilicate sand control new material and algae, can realize suction, solid water, solid fertile, improve soil aggregate, build the microenvironment of a suitable plant growing.
Certain arid area once adopted construction method of the present invention to administer near Beijing, pay a return visit after five months, and be greenweed Cheng Yin already, lush green a slice.Compare with the common species method for planting, its effect is (is 1.0 standards as a comparison with common species method for planting effect) as shown in Table 1:

Specific implementation method
The invention will be further described below in conjunction with embodiment: at first rice straw is woven into the straw rope that diameter is 20mm, and preceding 8 days of construction this straw rope is placed at normal temperatures soak 1.5 hours in the water-soluble rubbish strain liquid that concentration is 7PPM after, take out dry in the shade standby; And then other stalk is broken into the powder of straw of Φ 2.5mm, by powder of straw: barnyard manure is that 2: 1 weight ratio and barnyard manure is mixed into the powder of straw that contains barnyard manure; Then again by the powder of straw that contains barnyard manure: spirulina: cellular phyllosilicate sand control new material is 0.25: 0.035: 1 a weight ratio, and it is standby that this three is mixed into the stalk compound.Leaving earlier a series of width during construction on sandy land comes for the 150mm ditch, and will put into ditch by in-line through the straw rope that the rubbish strain liquid soaked, then by seed of river grass: the stalk compound is 0.02: 1 a weight ratio, they are mixed, afterwards the straw rope in the ditch with their dispensers on straw rope, after watering, earthing gets final product again.
