Abstract
The invention provides a humic acid-type calcium-magnesium-sulfur soil conditioner. The soil conditioner takes 17-30wt% of humic acid, 50-67wt% of desulfurized gypsum, 2-4wt% of ammonium sulfate, 2-3wt% of urea, and 7-13wt% of a magnesium fertilizer as the raw materials for processing and production. According to the requirements of the soil conditioner, a organic matter content is greater than or equal to 15.0%, total nitrogen is greater than or equal to 2.0%, calcium oxide is greater than or equal to 13.0%, magnesium oxide is greater than or equal to 2.0%, sulfur is greater than or equal to 8.0%, a water content is less than or equal to 15.0%, and the pH of the soil conditioner is 4-6.5. The soil conditioner of the invention contains abundant organic matters, active groups, available nitrogen, exchangeable calcium, magnesium and easily absorbable sulfur element. While improving saline-alkali soil, the soil conditioner can provide nitrogen and calcium, magnesium, sulfur as well as other secondary elements to crops in a balanced way. The soil conditioner provided in the invention can significantly improve the physiochemical properties of saline-alkali soil, promote crop growth, as well as improve and enhance crop quality and yield.
Description
Technical field
The present invention relates to agricultural technology field, be specifically related to a kind of humic acid type calcium magnesium sulphur soil conditioner and preparation method thereof.
Background technology
Along with a large amount of uses of a large amount of inorganic chemical fertilizers, the organic content of agricultural land soil is more and more lower, microbe population also lowering year by year, soil physical and chemical property worse and worse, the invention provides a kind of humic acid type calcium magnesium sulphur soil conditioner.Can improve the various defective modes of soil.
Humic acids is a large class black or the brown natural organic colloid compound of many condensed ring shape, contains the active group that a large amount of benzene nucleus, carboxyl, hydroxyl, phenylol etc. have stronger complexing, chelating and surface adsorption ability.Humic acids has good effect to strengthening soil fertility and improveing Soil structure.Desulfurated plaster is the industry byproduct that Wet Limestone-gypsum method flue gas desulfurization technique is produced, and it is carried out rationally utilizing is the project that governments at all levels vigorously advocate.The main component of desulfurated plaster is terra alba, and quality is better than most of plasters of paris, and has the advantages such as purity is high, stable components, objectionable constituent are few, granularity is little.Utilize the Ca in desulfurated plaster
2+can displace Na too much on salt affected soil colloid
+, significantly reduce pH, the basicity of soil, promote soil aggregate to form, thus improvement salt affected soil.Chinese patent application has been announced " acidic soil conditioner that contains coal-fired flue gas desulfurization solid waste " for No. 200610122407.7, this soil conditioner is mainly complexing or the sequestering action that utilizes humic acids, the concentration of the active iron in local adjustment soil, aluminium, manganese is carried out soil improvement, and improved effect is limited.Announced " product after sulfur dioxide absorption is processed into soil conditioner to be transformed for saline-alkali soil " for No. 200910142804.4, it is coarse that this soil conditioner is manufactured raw material, complicated component, and treating processes link is many, the cycle is long, and improved effect is limited.
Desulfurated plaster is combined with the natural organic matter humic acids that is rich in various active group, their special roles aspect improvement salt affected soil of common performance, and by science, adds ammonium sulfate, urea and fertiliser containing magnesium and make and have concurrently and can provide the soil conditioner of measuring nutritive element in quick-acting nitrogens and the calcium easily absorbing, magnesium, sulphur etc. to crop.In addition, because humic acids can reduce soil urease liveness, humic acids and urea can generate corruption-urea complex compound, and urea decomposition is slowed down, and reduce the volatilization of ammonia, thereby improve nitrogen utilization efficiency.Up to now, the present invention is not yet seen in report.
Summary of the invention
The invention provides a kind of humic acid type calcium magnesium sulphur soil conditioner and preparation method thereof, the element sulphur that soil conditioner of the present invention contains a large amount of organic matters, active group, quick-acting nitrogen, exchangeable calcium, magnesium and easily absorbs, improvement provides the moderate-elements such as nitrogen and calcium, magnesium, sulphur when salt affected soil to crop equilibration, improve soil physical and chemical property, promote plant growth, improve and the quality and yield that improves crop.
The technical solution used in the present invention is as follows for achieving the above object:
A humic acid type calcium magnesium sulphur soil conditioner, is characterized in that, take humic acids, desulfurated plaster, ammonium sulfate, urea, fertiliser containing magnesium is that Raw material processing is produced, and its weight percent is:
Humic acids 17-30%
Desulfurated plaster 50-67%
Ammonium sulfate 2-4%
Urea 2-3%
Fertiliser containing magnesium 7-13%,
Requirement, organic content >=15.0%, total nitrogen >=2.0%, calcium oxide >=13.0%, magnesium oxide >=2.0%, sulphur >=8.0%, moisture content≤15.0%, the pH of described soil conditioner is 4.0-6.5.
The preparation method of described humic acid type calcium magnesium sulphur soil conditioner, is characterized in that, comprises the following steps:
(1) feed intake: humic acids, desulfurated plaster are added in stirrer in proportion;
(2) be uniformly mixed, the rotating speed of stirrer is turn/min of 55-65;
(3) pulverize: urea granules is pulverized;
(4) secondary batching: ammonium sulfate, urea, fertiliser containing magnesium are added in stirrer in proportion;
(5) secondary stirring is mixed, and the rotating speed of stirrer is turn/min of 45-55;
(6) detect qualified after, packing warehouse-in.
This soil conditioner is black or grey black powdery loose matter, is applicable to plant the alkalescence of all kinds of crops and the improvement of saline-alkali soil such as grain, vegetables, melon and fruit, root food, flowers, medicinal material, tealeaves, cotton.Before crop sowing or before transplanting final singling, in conjunction with whole ground, execute 50 ~ 150kg for every mu, when turning over earthing, be sprinkled into, also can first evenly be sprinkled in field and carry out again tractor-ploughing and turn over.This product also can apply in the lump with base manure.
Beneficial effect of the present invention:
(1) regulate soil acidity or alkalinity, improvement soil property, chessom, improves soil permeability, prevents that soil epidermis crust from hardening, and reduces soil alkaline harm.
