Problems solved by technology

Since the special slow-release fertilizer for saline-alkali soil improvement contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic materials, it is more difficult to dissolve after granulation. Particles affect the quality and effect of the product
However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products

Embodiment 1

[0020] 25%~35wt% of medical stone, 5%~10wt% of potassium chloride, 5%~15wt% of mineral powder and 25%~30wt% of organic fertilizer, prepared from water, the sum of each component is 100%, the activity Solid bacteria include lactic acid bacteria, Bacillus subtilis, Bacillus megaterium, Trichoderma, Aspergillus niger, Monascus, Trichoderma harzianum, Aspergillus aculeatus and yeast, mineral powder is peat, zeolite, vermiculite, montmorillonite, calcium carbonate , one or more mixtures of expanded perlite, the fineness of the mineral powder is ≤200 mesh, the organic fertilizer contains decomposed manure, rapeseed cake fertilizer, straw, and the mixture of the manure, rapeseed cake fertilizer and straw The weight ratio is 5.5-7.5: 2.5-3.5: 0.5-1.5; the batching of the semi-finished granular saline-alkali water-retaining slow-release fertilizer is composed of the following components by weight percentage: 2-10% of high-viscosity attapulgite clay powder, acidified Attapulgite clay 5-...

experiment example 2

[0033] In 2015, 3 farmers including Liu Liguo in Zhengdian Town, Leling City, Dezhou City, applied more than 20 mu of the fertilizer described in Examples 1-3. The fertilizer in Comparative Example 1 was a compound biological compound produced by Shijiazhuang Zhongjia Fertilizer Technology Co., Ltd. Organic fertilizer (powder) (organic matter ≥ 45%, nitrogen, phosphorus and potassium ≥ 5%, effective viable bacteria ≥ 550 million / g, medium and trace elements ≥ 10%), according to the application instructions, 50kg / mu; a total of 2 applications during the growth period . ,

[0034] Compared with the fertilizer of Comparative Example 1, the acidity and alkalinity of the soil in saline-alkali land was significantly improved after applying the fertilizers of Examples 1-3, and the pH value of the soil decreased by more than 0.3, and the application of the fertilizer in Example 3 could make the pH value of the saline-alkali land decrease. Maximum, down 0.42. The nutrient content in ...

experiment example 3

[0036] Fertilization field test, the wheat variety is Xiaoyan 60, and 50-80 kg of the fertilizer described in Example 1-3 is applied per mu each time to study the effect of the fertilizer on wheat production increase in the present invention.

[0037] Fertilization amount and fertilization method: establish 4 treatments, handle one, apply 50 kg of the fertilizer described in Example 1 per mu; process two: apply 50 kg of the fertilizer described in Example 2 per mu; process three: apply 50 kg of the fertilizer described in Example 3 per mu; Process four: Mu Shi contrast example 1 fertilizer 50kg, contrast example 1 fertilizer is the compound bio-organic fertilizer (powder) of Shijiazhuang Zhongjia Fertilizer Technology Co., Ltd. (organic matter ≥ 45%, nitrogen, phosphorus and potassium ≥ 5.5%, effective viable count ≥ 500 million / g, medium and trace elements ≥ 10%), according to the application instructions, 50kg / mu; a total of 2 applications during the growth period.

Abstract

The invention provides a controlled release fertilizer special for saline alkali soil improvement. The controlled release fertilizer is characterized by being prepared from 25-35 wt% of medical stone, 5-10 wt% of potassium chloride, 5-15 wt% of mineral powder, 25-30 wt% of organic fertilizer and water, and the sum of the all components is 100%; the active solid strains include lactic acid bacteria, bacillus subtilis, bacillus megatherium, trichoderma, aspergillus niger, monascus, trichoderma harzianum, aspergillus aculeatus and yeast; the mineral powder is one or a mixture of peat, zeolite, vermiculite, montmorillonite, calcium carbonate and expanded perlite, the fineness of the mineral powder is less than or equal to 200 meshes, the organic fertilizer contains a fermented manure fertilizer, a rape seed cake fertilizer and straw, and the weight ratio of the fermented manure fertilizer to the rape seed cake fertilizer to the straw is (5-7.5):(2.5-3.5):(0.5-1.5).

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special slow-release fertilizer for saline-alkali soil improvement. Background technique [0002] The special slow-release fertilizer for saline-alkali soil improvement has comprehensive nutrients, which can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the special slow-release fertilizer for saline-alkali soil improvement enter the soil and form a symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic effect of the group. Beneficial bacteria produce a large number of metabolites in the process of growth and reprodu...
