Abstract
The invention relates to an improved small-hole in-situ restoration saline land plantation method; to build plantation, hole-like leveling is carried out on the saline land; a layer of broken corn stalks, a layer of cow dung and a layer of corn straws are sequentially laid at the hole bottoms; then the artificial biological matrix of fermented corn straws and cow dung is mixed with luvisol to form the artificially improved soil which is then laid in the holes, and saline-alkaline reducing agent is poured on the improved soil; the seedlings are planted in the holes, set and watered; finally, the artificially improved soil is accumulated around the permanently planted seedlings and coned, and then topsoil film former is laid on the conical artificially improved soil. To prevent the roots extending into the hole bottoms and contacting the luvisol to cause damage, a run-through feeding channel is dug between every two holes and filled with artificially improved soil to induce the roots to grow horizontally in the channel.
Description
Affiliated technical field:
The present invention relates to the preparation of biofermentation conversion zone and artificial bio-membrane's matrix, in-situ remediation method is shown native film forming agent and is sprayed, and is mainly used in to improve the soil physical arrangement and reduce salt and alkali component.
Background technology:
China is a large agricultural country, and agricultural development is one of important component part of the national economic development.Soil desertifies, the soil salinization is the MAIN SOILS problem that China faces, and there are salt wasteland and the 6700000 hectares of salination soils above 2,000 ten thousand hectares in China.Salt affected soil is meant harmful salts such as the chloride that contains potassium, sodium, calcium, magnesium in the soil, sulphate, heavy carbonate; Though or soil salt content is few, soil exchangeable sodium accounts for cation exchange capacity and has reached certain proportion.Principal character pH value is higher, contains harmful salinity, seriously restricts the growth of plant.
The reparation of vesicle improvement original position is to have utilized the medically thought of " skin-grafting ", the humus layer artificially that lacks on the saline-alkali bare land is filled, and be primary raw material with maize straw and cow dung, makes up saline and alkaline layer of bio-acidification resistance.Saline-alkali bare land is owing to the humus layer that lacks plant growing, and eluvial horizon is not suitable for taking root of root system of plant, by manually filling up humus layer, produces the matrix that is fit to plant growing artificially.In addition, the one of the main reasons that saline-alkali bare land forms be exactly evaporation discharge greater than rainfall, one deck table soil film forming agent by spraying has reduced the evaporation of moisture, keeps moisture.
Summary of the invention:
Main purpose of the present invention is the improvement saline land, in order to achieve the above object, the technical solution used in the present invention comprises: at first carry out cave-shaped whole ground on the saline land, excavated diameter 60cm, the vesicle of high 40cm, 1.5m at interval between two caves mixes the cave-shaped luvisol that digs out then wholely with the prior artificial bio-membrane's matrix that cure into maize straw and cow dung, it is standby to be modulated into artificial modified soil.Place mat one layer thickness is the maize straw of 10cm in the bottom, cave, continues on it and executes the cow dung that a layer thickness is 5cm, renews on it and executes the maize straw that a layer thickness is 10cm.Then, artificial modified soil is imposed in the cave, thickness is 5cm, and salt alkaline agent falls in pouring 1L-2L on it.Sapling is planted in the cave, the back tramps with one's feet repeatedly and steps on the native fixedly root system of artificial modified again, and root system and artificial modified soil is fully contacted, and waters the well water of about 60L on it again.At last, be that the center piling height is the artificial modified soil of 30cm with the field planting sapling, be conical, to prevent ponding in the cave, on conical artificial modified soil, use the native film forming agent of table again, run off to prevent artificial modified soil, and reduce soil evaporativeness.For preventing that root system from stretching into that the contact luvisol damages at the bottom of the cave, between two caves, excavate wide 20cm, the degree of depth is the connectivity of the 40cm ditch of looking for food, and fills up artificial modified soil in it, ties up to cross growth in the ditch to induce tree root.This method make cave-shaped whole ground, saline land the soil physics structure be improved significantly, soil density and salt and alkali component in the cave have been reduced, increased the content of organic matter around the root system in the cave, therefore the excessive evaporation accumulation of salt in the surface soil of ponding polysalt and dry season in the season cave that prevents to waterlog can guarantee that the tree of building can grow by normal growth.Solved the difficult problem of local cow dung contaminated environment, the discarded waste of a large amount of maize straws simultaneously.Advantage of the present invention:
1 improvement alkaline land soil structure has reduced soil density and salt and alkali component in the cave;
2 fall the salt alkaline agent belongs to acid, can neutralize from the soil bottom or the hole wall returns out saline and alkaline;
3 ditches of looking for food utilize the performance of plant intelligent, and root system extends to the place that is fit to growth, have solved because root system can not be grown downwards, draw nutrient and death;
4 artificial substratums are made up of cow dung, maize straw, and these things can be referred to as discarded object, and we as plant growth medium, for plant growing provides nutrition, have solved the trouble that discarded object brings again with it;
5 is that conical little mount is piled up at the center with the forest plantation nursery stock, has prevented the excessive evaporation accumulation of salt in the surface soil of ponding polysalt and dry season in the waterlogging season cave;
The native film forming agent of 6 tables prevents that artificial modified soil runs off, and reduces soil evaporativeness.
Embodiment:
Below, the present invention will be further detailed with embodiment, but it is not limited to any or the similar example of these embodiment.
1 piled up slaking 1-2 month with 2:1 with cow dung maize straw is broken.
2 dig diameter 60cm, the vesicle of high 40cm, and two caves are 1.5m at interval, dig out wide 20cm between two caves, the high 40cm connectivity ditch of looking for food, with the cave-shaped luvisol that digs out wholely with mix with the broken artificial bio-membrane's matrix that cure into cow dung of maize straw in advance, it is standby to be modulated into artificial modified soil;
3 is that the maize straw of 10cm is broken at cave bottom place mat one layer thickness, continues it on and executes the cow dung that a layer thickness is 5cm, and renewing on it and executing a layer thickness is that the maize straw of 10cm is broken.Then, artificial modified soil is imposed in the cave, thickness is 5cm, salt alkaline agent falls in pouring 1.2L on it, poplar seedlings is planted in the cave back fixedly root system of artificial modified soil again, tramp with one's feet repeatedly and step on, root system is fully contacted with artificial modified soil, water the well water of about 60L on it again;
4 usefulness artificial modified soil fill up the ditch of looking for food, and also water in the lump;
5 poplar seedlings with field planting are that the center piling height is 30cm, and radius is the artificial modified soil of 60cm, are conical, to prevent ponding in the cave;
6 use the native film forming agent of table again on conical artificial modified soil, be 2.5L according to porous upper soll layer 2mm computational chart soil film forming agent consumption, evenly spray on the artificial soil of taper;
After 7 improvement, willow growth in thickness, high growth and the hat width of cloth all improve nearly 3 times, and soil density reduces 1000kPa approximately, and growth of poplar is improved significantly.
