Description
One, technical field
The present invention relates to a kind of saline-alkali land soil conditioner and preparation method thereof, belong to the technical field of alkaline land soil improvement.
Two, background technology
It is estimated, China has the agriculture and forestry organic waste material more than 1,000,000,000 tons arbitrarily to be disposed every year or big area is burned, and not only causes the waste of large number of biological matter resource, also cause serious air environmental pollution.China advocates " recycling " at present energetically, according to physics, the chemical feature of agricultural wastes, by certain technique means, is down to and is converted into favourable to social production, environment for human survival to be had to actively improvement material.Containing multiple nutritional components in waste agronomic crop, as nitrogen, phosphorus, potassium, calcium, magnesium etc., these agriculture and forestry organic waste materials are utilized to become the focus of modern society's research.
Saltings refers to and comprises solonchak, alkaline earth and various salinized soil by the class soil that salinization or alkalization are formed.The porosity of alkaline land soil is little, and fertility is low, and be easy to harden, ventilative water permeability is poor, and the mineralization degree of C, N is low, and in soil, the activity of enzyme is suppressed, and affects microbic activity and organic conversion.Salt ion excessive in soil, to destroying plant cell tissue, hinders plant-growth, and the soil that salinization and alkalization is high even causes root system of plant to rot, and causes plant directly dead.
The salinization of China is ploughed and is accounted for 6.62% of arable land, the whole nation, and scientific development utilizes saltings, and in today that cultivated land resource reduces day by day, tool is of great significance.At present, the soil improvement method in domestic saltings and technology are summed up roughly as follows: (1) is physically improved: level land, deep plough sun the earth which has been ploughed up, loosen the soil in time, raise landform, microcell is improved the soil; (2) water conservancy improvement: fill with deploying cover, storage fresh water on saline alkali land for leaching, washing salinity by irrigation, underground salt discharge; (3) chemical modifying: gypsuming, phosphogypsum, calcium superphosphate, humic acids, peat, acid-sludge etc.; (4) biological modification: rice cultivation, plantation salt-tolerant plant sesbania etc., or use germ fertile.Using soil improvement agent improvement saltings and have the advantages such as easy and simple to handle, with low cost, use range is wide, is the most a kind of technique means reducing the use of salting of soil degree in modern agriculture.Increasing scientific worker turns one's attention to soil improvement agent, not only optimizes the formula of soil improvement agent, also simplify preparation method.Up to the present, establish a series of novel method preparing soil improvement agent, and utilized various waste for starting material, achieve the doulbe-sides' victory of utilization of waste material and alkaline land improving.No. CN1526686 patent document discloses a kind of alkaline land soil improvement special fertilizer and working method thereof, and it is main raw material with gypsum, adds the various agricultural wastes being rich in organic matter, has prepared a kind of alkaline land soil improving fertilizer of green economy.No. CN103642501A patent document discloses a kind of saline-alkali land soil conditioner, it take flue gas desulfurization waste as main raw material, add and be variously rich in organic agriculture and forestry organic waste material and various biological raw material, prepared a kind of saline-alkali land soil conditioner of environmental protection.The shortcomings such as it is poor that above patent all exists agriculture and forestry organic waste material decomposition, and nutritive element is not enough, are difficult in the area that soil is relatively barren promote.Therefore, find one and effectively can utilize agriculture and forestry organic waste material, the soil improvement agent enriching the necessary nutritive element of plant-growth can be rich in again, become a technical problem urgently to be resolved hurrily.
Three, summary of the invention
In order to solve the technical problem that above-mentioned saline-alkali land soil conditioner exists, the invention provides a kind of saline-alkali land soil conditioner and preparation method thereof; By ball milling oxidized activating modification agriculture and forestry organic waste material; material is made to have excellent pore texture and biological degradability; by with inorganic accelerator and the further composite salinization and alkalization that can reduce soil of organic promoter; improve the physical behavior of soil and the crumb structure of soil; reduce the pH value of soil; increase soil fertility, and can improve agricultural output and quality, protective plant is healthy.Present method not only achieves the regeneration of agriculture and forestry organic waste material, reduces cost of investment, can also improve edatope simultaneously, and increasing fertilizer efficiency, is a kind of saline-alkali land soil conditioner of environmental protection.
A kind of saline-alkali land soil conditioner the agriculture and forestry organic waste material 20 ~ 50 parts of activation, inorganic accelerator 0.5 ~ 40 part and organic promoter 0.5 ~ 30 part is mixed within 12 ~ 48 hours, to obtain in 60 DEG C of dryings.
