Description

Double-layer sand inclusion planting method

Technical field

The present invention relates to a kind of method of tree planting.

Background technology

The process of tradition method of planting operation is: sapling is put into tree well, keep sapling to be in vertical state, banket after watering sufficient water, tread.This method is used till today always, and the problem that this method exists is: sticking heavy soil itself just has the shortcoming of gas permeability difference, above-mentioned in addition operation, and the soil consolidation more that can become, unfavorable for the growth of sapling root system; Simultaneously, clay easily waterlogging is easily non-irrigated, also can influence taking root, survive and growing of sapling.The shortcoming that traditional tree-planting method exists is particularly evident in the higher area of consistency of soil.

Summary of the invention

The object of the present invention is to provide a kind of double-layer sand inclusion planting method, this method can either be improved the gas permeability of trees ' root, also can improve the stability of soil moisture, helps taking root, survive and growing of sapling.

For achieving the above object, double-layer sand inclusion planting method provided by the invention adopts following steps: (1), sapling is put into tree well, keep sapling to be in vertical state, cover with the root of sand sapling, sand is that the center of circle piles taper with the trunk around root; (2), banket near face of land place, tread, water permeable; (3), treat that water has oozed after, cover one deck sand again, be filled to ground one tree well flat; (4), earth up around the sapling base portion shape in heaps, and clap tight.

In addition, the present invention also comprises following content: the shape in heaps of earthing up around the sapling base portion, and clap tight after, sapling is added supporting; The sand of overlay tree shoot root portion is that the center of circle piles taper in root on every side with the trunk; The thickness that is in the sand of tree well middle and upper part is 2～3mm.

Transplanting trees, to survive many, the fast key of growth be to improve the ability that root system absorbs rich water rapidly, and its prerequisite is to make the quick root of hair of sapling, and the aqueous vapor of rhizosphere fully and coordination is the fast necessary condition of root of hair.

In the method for planting provided by the invention, not only adding sand but also add soil in tree well, is design feature and the fertile physicochemical property of aqueous vapor that has made full use of two kinds of materials.Contain a large amount of soil clay particles and organic substance in the soil, liquid manure is had stronger absorption hold accumulation of energy power, but after soil is admitted moisture, moisture is difficult to discharge, and is full of the hole of soil, and air is therefrom squeezed away, cause the soil anoxic, influence root system generation and growth.Soil also can form the capillary that is communicated with up and down after meeting water in the soil body, the moisture in the soil moves on meeting under the irradiation of sunlight is rapid along capillary, is evaporated away, causes the soil lack of water.In the soil in summer, the variation of this aqueous vapor is often very violent, thereby makes soil body drought and waterlogging frequent, and this is to the root of hair of sapling, and it all is very disadvantageous surviving.Sand is then on the contrary.Owing to do not contain clay, therefore can not form suction-operated to rich water, meeting water can very fast seepage, protects fertile water retention capacity extreme difference.But therefore have well refreshing water permeability, sand is overlying on the sapling root, can increase the rhizosphere air, has formed countless " little air chamber " at rhizosphere, helps root growth; Owing to do not contain clay, sand can not form capillary, is folded in the soil, can cut off the capillary of soil, stops the soil moisture that summer, violent evaporation caused up rapidly, thereby plays maintenance soil moisture, reduces the effect of moisture loss.

The retention capacity of soil that is clipped in the middle by double-deck sand is strong, down, by the layer of sand holder, helps the too much moisture of downward filtering, increases the gas permeability of soil in rainy season; Upwards, the capillary that moves on the moisture is blocked by sand bed, can reduce the evaporation loss under the summer high temperature, alleviates damage caused by a drought.This is to preventing the big rise and big fall of soil aqueous vapor, and it is favourable keeping the aqueous vapor balance of rhizosphere soil.The fertilizer-preserving ability of soil is strong, wherein is rich in various nutriments, can provide abundant mineral nutrient for the sapling growth.This piece soil has become trees ' root " rich water storehouse ".In like manner, the following soil in the end, hole under the effect of bottom sand, can effectively keep moisture, improves the drought-resistant ability of sapling.

As seen, double-layer sand inclusion planting method provided by the invention, be exactly according to above-mentioned two kinds of materials aqueous vapor bias separately, learn from other's strong points to offset one's weaknesses, the balance combination, configuration according to qualifications, under the interaction of " little air chamber " and " rich water storehouse ", build at the rhizosphere of newly planting forest that a kind of water conservation permeability has both, the soil environment of aqueous vapor conditional stability, thereby can promote the growth of tree root significantly, improve the ability of quick draws water of plant and nutrient, improve survival rate and growth rate.Double-layer sand inclusion planting method provided by the invention is particularly useful for the higher area of consistency of soil.
