Abstract
The invention discloses a saline-alkali land improving and fertilizing agent and a preparation method thereof. The saline-alkali land improving and fertilizing agent are mainly prepared from 20 to 40 portions of fly ash, 10 to 20 portions of humic acid and 5 to 10 portions of organic substance through processes of crushing, matching and mixing, granulating, drying, cooling, sieving, magnetizing and the like. Compared with the prior art, a product of the invention has the advantages of short period for improving the saline-alkali land, high efficiency and low cost; if 50 kilograms of product is applied to each acre as base fertilizer, the seedling emergence rate of planted crops can reach 98 percent, for example, 406 kilograms of wheat is harvested in each acre and is equal to the planting harvest of the normal soil, and after the harvest, the salt content of the soil is 0.55 percent and the desalination rate reaches 47 percent through soil measurement, so that the soil granule structure is improved; and the product can reduce the salt and restrain the alkali, is soil improvement agent, also can be used as fertilizer, reduces the planting cost, has the same using method as a common fertilizer when the product is used as the fertilizer, has remarkable fertilizer efficiency in saline-alkali and poor soil, and can increase the yield by 10 to 30 percent relative to different crops compared with the used common fertilizer. Therefore, the saline-alkali land improving and fertilizing agent not only can improve the soil granule structure, but also can accelerate the improvement of soil desalination; meanwhile, the saline-alkali land improving and fertilizing agent is fertilizer, greatly reduces the planting cost of peasants, and improves the planting income of the peasants.
Description
Technical field:
The present invention relates to a kind of saline-alkali land improving and fertilizing agent and preparation method thereof.
Background technology:
Alkaline land improving is a global problem always, and a lot of countries all are devoted to the improvement and the utilization in saltings.At present, the method for alkaline land improving and improvement is a lot, like the improvement of the biological processes of pioneer crops such as rice cultivation, clover, and the water desalinization of soil by flooding or leaching physically improved, and with the chemical modifying of gypsum and sulphur etc.But these modification methods exist the improvement cycle long, have high input, the shortcoming that water consumption is big.There is the saltings more than 14.87 hundred million mu in China and receives the middle-and-low-yielding fields of saline and alkaline harm, wherein much reasonably developments and utilizations.The today that receives the invasion and attack of urbanization occupation of land, desertification, desertification, salinization in the arable land and reduce day by day, the improvement in saltings and improvement seem more and more important.It is just not obvious that existing alkaline land modifying agent is higher than the effect of 0.6% saltings to salinity, and its crop seedling rate is lower than 40%, and surviving rate and output are low especially.Chinese patent CN 1631857A discloses a kind of saline-alkali land improving and fertilizing agent and preparation method thereof, comprises microbial composite bacteria liquid and siccative, and described microbial composite bacteria liquid is made up of Trichodermareesei, plant lactobacillus, yeast saccharomyces cerevisiae and actinoplanes missouriensis; Shortcoming is that the raw material sources face is narrow, for scale operation certain difficulty is arranged, and the preparation method is complicated; Long to the saline-alkali land improving and fertilizing cycle, usage quantity is bigger, and need use 2-3 time every year; To use continuously 3 years; Just execute and must turn over the plough soil, application process is comparatively complicated, and fertilizer efficiency is limited.
Summary of the invention:
It is short to the purpose of this invention is to provide a kind of improvement getting fat saltings relative cycle, and usage quantity is few, and application process is simple, and cost is lower, and the higher a kind of saline-alkali land improving and fertilizing agent of fertilizer efficiency and preparation method thereof.
Fertilizer synergist of the present invention is mainly processed by the raw material of the component of following weight: flyash: 20～40 parts, and humic acids: 10～20 parts, organic matter: 5～10 parts.
Above-mentioned humic acids is: a kind of in xanthohumic acid, the potassium humate.
Above-mentioned organic matter is at least a in the fulvo acid potassium, Sodium salts humic acids, humic acids amine of purification by liquid extraction from weathered coal.
Above-mentioned saline-alkali land improving and fertilizing agent contains: in nitrogen, phosphorus, potash fertilizer and the powdered iron ore any at least two kinds, wherein nitrogenous fertilizer: 8～30 parts, phosphate fertilizer: 10～30 parts, potash fertilizer: 1～5 part of 5～10 part, powdered iron ore.
Above-mentioned nitrogenous fertilizer can be a kind of in urea, ammonium nitrate, sulfuric acid amine and the phosphamide, phosphate fertilizer can be compound phosphoric acid one amine, phosphoric acid diamines, and potassium primary phosphate in a kind of, potash fertilizer can be a kind of in vitriolate of tartar, the Repone K.
Above-mentioned saline-alkali land improving and fertilizing agent is to process through following method:
Pulverizing → proportioning mixes → granulation → oven dry → cooling → screening → magnetization → metering packing;
Pulverize: various materials are pulverized the particle for≤180 microns;
Proportioning is mixed: by said composition by weight proportioning, pH value is preferably between 5.5～7.5, mixes the back and adds 5～8 parts of stirrings of sticker, and then add 5～10 parts in water, stirs, and said sticker can be a kind of in organic zeyssatite or the inorganic bentonite;
Granulation: granulating and forming in tablets press, particle diameter are 1.5～5 millimeters;
Oven dry: in dryer, oven dry in 5～10 minutes under 110～200 ℃ the temperature;
Cooling: be cooled to below 40 ℃; Preference is 15～40 ℃;
Screening: with sifted component selections 1.5～5 mm granules;
Magnetization: the particle that sieves out through magnetizer, was magnetized under 1500～4000 Gausses' magneticstrength 2～8 seconds, carry out weighing and pack getting final product.
Compare with existing other saline-alkali land improving and fertilizing agents, the present invention is short to the alkaline land improving cycle, efficient is high, cost is low, and improvement fertilizer synergist of the present invention is used 50 kilograms for every mu and made base fertilizer, and plantation farm crop seedling rate can reach 98%; As: mu is received 406 kilograms of wheats, equates with the plantation results of normal soil, and after the results; Through soil surveying, its saliferous 0.55%, ratio of desalinization reaches 47%; Having improved soil aggregate, can press salt to press down alkali, is soil improvement agent; Can be used as fertilizer again, lowered planting cost, as fertilizer sources uses identical with the common fertilizer method of use; And fertilizer efficiency is remarkable in saline and alkaline and lean soil, with respect to different crops, than using common chemical fertilizer can increase production 10-30%.So the present invention not only can improve soil aggregate, can also accelerate the improvement of soil desalination, be again fertilizer simultaneously, reduce peasant's planting cost greatly, improved the income of peasant planting.
