Abstract
The invention relates to a saline-alkali soil modifier and a preparation method thereof. The preparation method comprises the following steps: mixing 5-20 parts of humic acid, 15-30 parts of heavy calcium carbonate, 5-10 parts of solid sulphuric acid, 8-15 parts of farmyard manure, 3-7 parts of trace element compound and 1-3 parts of bone meal to pelletize; using 0.3-1 part of biological bacterium to pelletize; and mixing the obtained particles, adding 10-20 parts of nitrogen fertilizer, 5-14 parts of phosphatic fertilizer and 3-8 parts of potassic fertilizer to mix evenly and prepare the saline-alkali soil modifier. Pig manure and chicken manure are used as carrier to be combined with the saline-alkali soil modifier and prepare granule, the granule is applied 3cm and 10cm below seeds, thus the saline-alkali concentration around the root systems of the seeds can be reduced, the circular damage of the return of saline-alkali in deep underground on the root systems of crop can be suppressed, a good ecological environment can be created for the root systems of crop and the aims of strong root systems, more and stronger roots, luxuriant branches and leaves, high and stable yield can be realized. The technology can be used in the sustainable development of Chinese agriculture, thus the farmer with a limited land can have higher income.
Description
Technical field
The invention belongs to soil and regulate material and preparation method, particularly relate to a kind of alkaline land modifying agent and preparation method.
Background technology
The injury of nitre attitude alkali in the saline and alkaline arable soil, the root system of soda salt pair farm crop is very serious, and after the root system of farm crop was subjected to saline and alkaline murder by poisoning, root system development was bad and early ageing also is the main reason of multiple kinds of crops disease simultaneously.Low, the poor quality of grain yield.Because salinity is many in the soil, alkalescence is big, and the soil organism is destroyed and leaching loss, and trace element is in great shortage, show as when wet glutinous, hard when doing, the normal adularescent salt alkali precipitation of soil table, ventilation, permeable bad, the farm crop root system often has poisoning, mashed root, the phenomena of mortality.Can not be utilized by crop absorption even at this moment dropped into a large amount of fertilizer, cause the negative effect of the low output of high investment.The saline and alkaline cultivated area of China accounts for 1/4th of total area under cultivation, improves the soil physical chemistry present situation in saline and alkaline arable land, the grain yield in the saline and alkaline arable land of raising, is an important content implementing national agriculture-countryside-farmer's policy.In order to allow the peasant on limited soil buy grain more, to increase income, for the Sustainable development of China's agricultural, the improvement of saline and alkaline thus arable land is imperative.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, and a kind of alkaline land modifying agent and preparation method are provided.
Alkaline land modifying agent of the present invention is to be made by weight by following component: 3～8 parts in 15～30 parts of 5～20 parts of humic acid, heavy acid calcium, 5～10 parts of solid sulphuric acids, 8～15 parts of farm manures, 3～7 parts of trace compounds, 1～3 part of bone meal, 0.3～1 part of biological bacteria, 10～20 parts in nitrogenous fertilizer, 5～14 parts in phosphate fertilizer and potash fertilizer;
Described farm manure, its water ratio are 10～18%;
Described trace compound: be to be mixed and made into for 8～15 parts by 5～10 parts of ammonium molybdates, 20～30 parts of boraxs, 20～30 parts in ferrous sulfate and zinc sulfate;
Described humic acid is Ulmic acids, xanthohumic acid and ulmic acid;
The umber of being mentioned among the present invention is parts by weight.
Its preparation method:
A, with 15～30 parts of 5～20 parts of humic acid, heavy acid calcium, 5～10 parts of solid sulphuric acids, 8～15 parts of farm manures, 3～7 parts of trace compounds and 1～3 part of mixing granulation of bone meal;
B, with 0.3～1 part of granulation of biological bacteria;
C, the particle that a, b step are made mix mutually, add 3～8 parts in 10～20 parts in nitrogenous fertilizer, 5～14 parts in phosphate fertilizer and potash fertilizer again, mix, and promptly make alkaline land modifying agent.
Biological bacteria, EM(EffectiveMicroorganesms, be called for short EM) be the abbreviation of effective microorganism English word, it is with light and multiple microorganism compound a kind of typing microbial inoculums of cultivating in same state such as flora, yeast flora, lactobacillus, actinomycetes, phosphorus bacteria, vinelandii and potassium bacterium.Be brown translucent liquid, the pH value is between 3.5 ~ 4.5.Market is on sale.
Add humic acid, solid sulphuric acid etc. in the modifying agent of the present invention, can discharge the material of the salt alkali concn of can degrading in being manured into soil endlessly.Saline and alkaline toxic substance is degraded in the soil, and the farm crop root system is avoided its injury, and root system development is good.
The function that adds biological bacteria in the modifying agent of the present invention: contain bacteria agents such as phosphate solubilizing bacteria, potassium solubilizing bacteria, actinomycetes in (1) bacteria agent, can solidify the invalid phosphorus potassium that hardens in soil and replace activation using chemical fertilizer for many years.Adopt sodium ion sorbent material, organic acid neutralization reaction principle, ion exchange principle, saline and alkaline arable land pH value and content are reduced, improve and the land productivity of fostering and apply fertilizer.Solidifying the soil that hardens can be more and more loose, is beneficial to growing of farm crop root system, can improve chemical fertilizer utilization ratio.(2) the high-quality enhanced biological bacterium in the product breeds in the organic acid that discharges of fission in soil and toluylic acid, succsinic acid, can reduce the salt alkali concn, and the soil physical chemistry present situation improves.(3) biological bacteria produces a large amount of polysaccharide in reproductive process, is the important substance of recovering soil aggregate, and the energy chessom, makes the saline and alkaline leaching in the arable land, suppresses the accumulation of salt in the surface soil.(4) after the phosphate solubilizing bacteria in the biological bacteria, potassium solubilizing bacteria, actinomycetes, genus bacillus can activate the invalid phosphorus potassium displacement in the soil, phosphorus potassium utilization ratio improved.
The function of trace compound: trace element supplement can satisfy the farm crop whole growing to multiple nutrient demand, accomplishes balance fertilizing.Because having, trace element promotes growing, improve photosynthetic utilization ratio, improving the requisite nutritive substances of farm crop such as setting percentage of crop.In the crop growth process,, play an important role though consumption is little.
Alkaline land modifying agent of the present invention, do carrier with pig manure, chicken manure, the compound granule of making, impose on 3cm under the seed, 10cm place, can reduce concentration saline and alkaline around the seed root system, also can suppress underground deep layer and return the back on saline and alkaline to the circulation injury that the farm crop root system causes, be that the root system of farm crop is created a good ecotope, realizes that well developed root system, Gen Duogen are strong, flourishing, the purpose of stable high yield.Present technique to the Sustainable development of China's agricultural, be that the peasant increases more income on limited soil.
