Description
Technical field
What the present invention relates to is a kind of modifying agent improving alkaline land soil performance, is specifically related to a kind of for rape alkaline land modifying agent and manufacture method thereof.
Background technology
Salting of soil is the major obstacle factor that restriction China's agricultural development and integration capability improve always.Data shows, China's salinized soil is distributed in North China and the Northwest more, and the wide area of scope is large, if do not strengthen curing and prevention dynamics, will directly affect China's agricultural productivity and grain security, Peanut Crop is as main the eating of China, oil crops, there is in the northern area of China cultivated area widely, and the infringement in the saltings that the northern area of China is subject to is particularly serious, for this reason, the production of peanut and output are affected larger, salting of soil Crack cause is mainly: be that rainfall is few, evaporation is strong, make deep soil saline and alkaline on to move table poly-, cause primary salinization, the growth of salt alkali content height grievous injury Peanut Root System in soil in saltings, saline and alkaline moves and makes various trace elements in soil not enough, cause Peanut Crop growth seedling carefully modest, and harden in salinized soil earth's surface, cause peanut fruit head less, output reduces.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of modifying agent for peanut saltings and manufacture method thereof, the effect such as realize water conservation, fertilizer conservation, salt reduction, pressure alkali, loosen the soil.Its main method is: be aggregated in by sodium acrylate graft on weathered coal, then with attapulgite with phosphogypsum is composite makes alkaline land modifying agent.Its cardinal principle is: cemented out by the sodium ion being adsorbed on soil colloids by the ion exchange of phosphogypsum; Water retention is played by the sodium polyacrylate be grafted on weathered coal; By phosphogypsum by the carbanion solidification (CaSO in deep subsoil water body

3), thus soil pH value falls; Soil pH is reduced and can chessom by the acidity effect of weathered coal; The effect keeping chemical fertilizer nutrient is played by attapulgite; The usage quantity of trace compound is little, but trace compound effectively can supplement and meet farm crop whole breeding times to the demand of multiple nutrient, accomplish balance fertilizing, trace element has growing of promotion crop, improve photosynthetic utilization ratio, improve the per unit area yield of peanut, though consumption is little, play an important role.
The present invention is achieved by the following technical solutions, and a modifying agent of cultivating peanut saltings, by lime, phosphogypsum, attapulgite, weathered coal-sodium polyacrylate mixture and trace compound composition, is characterized in that: according to weighing scale, by 1-2 part lime, 1-3 part phosphogypsum, 4-6 part attapulgite, 1-2 part weathered coal-sodium polyacrylate mixture, the trace compound of 1-2 part mixes and forms, described lime fineness is 100-160 order, described phosphogypsum fineness is 100-160 order, the fineness of described attapulgite is 100-160 order, described weathered coal-sodium polyacrylate mixture is by weight, by the sodium acrylate Homogeneous phase mixing of the weathered coal of 8 parts and 3 parts, then be added to the water and be made into the suspension liquid that concentration is 90g/L, at 25-28 DEG C, stir 10-15 minute, thus by sodium acrylate graft copolymerization at weathered coal on the surface, dry, pulverize to 100-160 order in 70-72 DEG C afterwards and obtain, described trace compound is by 3-5 part ammonium molybdate by weight, the borax of 10-15 part, the zinc sulfate of 20-30 part mixes, and the fineness of trace compound is 100-160 order.
The one modifying agent manufacture method of cultivating peanut saltings, is characterized in that, comprise the steps:
(1) fineness of lime is that 100-160 order is stand-by;
(2) to be broken to 100-160 order stand-by for phosphogypsum powder;
(3) attapulgite is crushed to 100-160 order dry powder and irradiates under gamma ray (6MeV, 30kGy) and obtain stand-by in 20 minutes;
(4) weathered coal-sodium polyacrylate mixture is by the weathered coal of 8 parts and the sodium acrylate Homogeneous phase mixing of 3 parts, then be added to the water and be made into the suspension liquid that concentration is 80g/L, at 30 DEG C, stir 15 minutes, thus by sodium acrylate graft copolymerization at weathered coal on the surface, dry, pulverize to 100-160 order in 70 DEG C afterwards obtains stand-by;
(5) trace compound is mixed by the borax of 3-5 part ammonium molybdate, 10-15 part, the zinc sulfate of 20-30 part by weight, and the fineness of trace compound is 100-160 order;
(6) by weight, the trace compound 1-2 part Homogeneous phase mixing in weathered coal-sodium polyacrylate mixture 1-2 part, (5) in the attapulgite 4-6 part in the lime 1-2 part in (1), the phosphogypsum 1-3 part in (2), (3), (4) is obtained this modifying agent.
One application method of modifying agent of cultivating peanut saltings, it is characterized in that: by weight, the modifying agent obtained is added in fertilizer or urea or Chemical Mixed Fertilizer according to 10-15% ratio, namely granulation obtains alkaline land improving fertilizer, alkaline land improving urea and alkaline land improving Chemical Mixed Fertilizer, the modifying agent obtained evenly is spread fertilizer over the fields at soil surface according to every mu of 8kg consumption, then plough, the consumption of obtained improving fertilizer according to every mu of 30-50kg is evenly spread fertilizer over the fields at soil surface, then ploughs.
The present invention has the following advantages compared to existing technology:
(1) the present invention is compared with common chemical fertilizer, apply fertilizer Deng nutrient, soil humidity more than 10% can be increased, reduce soil and be harmful to salinity (sodium ion and carbanion etc.) more than 10%, improve determining cation exchange capacity of soil more than 5%, reduce nutrient loss more than 15%, make crop yield more than 10%, the multiple efficacies such as there is significant water conservation, fertilizer conservation, salt reduction, pressure alkali, loosen the soil.
(2) phosphogypsum adopted in the present invention is mainly the by product that fertilizer plant produces phosphate fertilizer, compared with the desulfurated plaster used in existing alkaline land modifying agent patent, there is reserves large (about more than 10 times), the large advantage of cost low (low more than 50%) two.
(3) weathered coal adopted in the present invention, compared with humic acid in existing alkaline land modifying agent patent, has the advantages such as reserves are large, cost is low.
