Problems solved by technology

At this time, although there is water in the soil, the crops cannot absorb and utilize it, causing the physiological drought of the crops, resulting in poor growth of the crops, and in severe cases, they wither and die.
(2) The direct toxic effect of salt
(3) Unbalanced soil nutrients
(4) Deterioration of soil physical properties
A certain amount of soluble salt in the soil, especially sodium salt, can disperse the soil particles and destroy the structure, causing the soil to be muddy when it is wet and hard when it is dry, with poor permeability and poor tillability, seriously affecting the quality of tillage.
(5) The water, fert

Embodiment 1

[0031] The preparation steps are as follows: mix the crushed crop straw, rice bran and the waste liquid slag of the monosodium glutamate factory according to the weight ratio of 1:1:2 and pile them up; (provided by Nanjing Agricultural University, the main components are cellulolytic bacteria, bacillus, yeast and mold), stir and mix evenly; when the temperature of the pile rises to 55~65℃, turn the pile, after 14~17 days, The heap body reaches a decomposed state, at this time, the water content is 26-35%, and the organic fertilizer is obtained; according to the proportion of parts by weight, 160 kg of monoammonium phosphate, 200 kg of urea, 150 kg of humic acid, 300 kg of organic fertilizer, and saline-alkali improvement Add 190 kg of conditioner to the mixer in order to stir, and after mixing, feed the material to the drum granulator for granulation; the granulated fertilizer is sieved and packaged to obtain the finished salt-inhibiting fertilizer for rape in coastal sa...

Embodiment 2

[0035] After the raw materials are prepared in proportion, they are granulated by drum method. During the granulation process, the granulation effect is adjusted by water to make it meet the national organic and inorganic compound fertilizer standards. The amount of the above two formulas can produce 1000 kg of finished special fertilizer, the nutrients are 12-8-0, and the contents of organic matter and amino acid are respectively above 20% and 1%, the content of gypsum is above 10%, and it contains 2 kg of borax. On the coastal saline soil with moderate salinization, applying 50 kg of salt-inhibiting special fertilizer per mu in the form of base fertilizer, and other cultivation and management measures can enhance the saline-alkali resistance of rapeseed, and increase the yield by an average of 10% compared with traditional fertilization. At the same time, it can significantly reduce Na in the surface soil during the growth period of rape + and Cl - content, with an ...

Embodiment 3

[0039] The preparation steps are as follows: mix the crushed crop straw, rice bran and the waste liquid slag of the monosodium glutamate factory according to the weight ratio of 1:1:2 and pile them up; (provided by Nanjing Agricultural University, the main components are cellulolytic bacteria, bacillus, yeast and mold), stir and mix evenly; when the temperature of the pile rises to 55~65℃, turn the pile, after 14~17 days, The heap body reaches a decomposed state, at this time, the water content is 26~35%, and the organic fertilizer is obtained; according to the ratio of parts by weight, 170 kg of monoammonium phosphate, 220 kg of urea, 200 kg of humic acid, 300 kg of organic fertilizer, and saline-alkali improvement Add 200 kg of conditioner to the mixer and stir in turn. After mixing, feed the material to the drum granulator for granulation; the granulated fertilizer is sieved and packaged to obtain the finished salt-inhibiting fertilizer for rape in coastal saline soil...

Abstract

The invention relates to a salt-restraining special fertilizer for seashore solonchak rapes, comprising the following materials in parts by weight: 250-300 parts of organic fertilizers, 150-200 parts of humic acids, 130-170 parts of monoammonium phosphate, 200-220 parts of urea and 150-200 parts of saline and alkaline improved conditioners. The salt-restraining special fertilizer for the seashoresolonchak rapes is prepared by the following steps of: uniformly mixing grinded crop straws, rice chaff and waste liquid residues of a gourmet powder factory, and then piling up; adding a fibrinolysis compound bacterial agent, uniformly stirring and mixing, and piling up to obtain the organic fertilizers; sequentially adding the monoammonium phosphate, the urea, the humic acids, the organic fertilizers and the saline and alkaline improved conditioners to a stirrer and stirring; and then feeding into a rotary drum granulator for granulation so as to obtain a finished product, i.e. the salt-restraining special fertilizer for the seashore solonchak rapes. In the preparation of the salt-restraining special fertilizer, the organic wastes obtained from agricultural and industrial production areeffectively used as raw materials, a certain amount of the humic acids and agricultural gypsums are added and a scientific formula and a unique production process are adopted; in addition, the prepared novel fertilizer is applied to the seashore solonchak rapes and other crops and plays an important role.

Description

technical field [0001] The invention belongs to the technical field of fertilizers for agricultural production, and in particular relates to a salt-suppressing special fertilizer for rape in coastal saline soil and a production process thereof. Background technique [0002] Soil salinization is a global problem that affects the sustainable development of agriculture and the ecological environment. According to statistics, the area of ​​salinized soil in the world accounts for about 1 / 3 of the earth's land area. In my country, the scale of saline soil is quite large. Among the 100 million hectares of cultivated land, there are about 5.374 million hectares of saline soil, and another 44.088 million hectares of saline-alkali wasteland are distributed in Northwest, North China, Northeast China and coastal areas. Studying special fertilizers for salt-tolerant crops in coastal saline soil is one of the effective measures to control saline soil. It is of great significance to adju...
