preparation example Construction

[0025] The invention provides a preparation method and application method of saline-alkali land ecological improvement organic fertilizer, which comprises

[0026] The following steps:

[0027] A fermented manure preparation

[0028] a mix chicken manure, pig manure and cow manure in a weight ratio of 3:2:5 to obtain mixed manure;

[0029] b. Crush the straw into 5-8 cm sections, then mix it with the mixed manure at a ratio of 3:7 and build a heap;

[0030] c. Add starter and add water to 55% fermentation; wait until the temperature in the heap rises to 63°C and turn the heap until the temperature no longer rises; then dry and pulverize to obtain fermented manure;

[0031] B Improved material composition: peat 30%, humic acid 20%, superphosphate 20%, sulfur 10%, calcium-based bentonite 10%, polyacrylic acid 5%, phosphoric acid 5%;

[0032] Trace element additive composition in C: ammonium phosphate 20-25%, ammonium sulfate 40-45%, zinc sulfate 3-5%, magnesium sulfate 8-10%,...

Embodiment 1

[0039] Step D: Mix and stir the fermented excrement, improved materials, and medium and trace element additives in a weight ratio of 89:10:1, then add 1% organic aqueous solution of hydrolyzed polymaleic anhydride, and adjust the pH value to 3.5; Improved organic fertilizer;

[0040] Using the organic fertilizer to carry out saline-alkali application experiments, the total salt content decreased by 33.1%, and the pH value decreased by 1.31.

Embodiment 2

[0042] Step D: Mix and stir the fermented excrement, improved materials, and medium and trace element additives in a weight ratio of 90:9:1, then add 2% organic aqueous solution of hydrolyzed polymaleic anhydride, and adjust the pH value to 5; Improved organic fertilizer;

[0043] Using the organic fertilizer to carry out saline-alkali application experiments, the total salt content decreased by 31.9%, and the pH value decreased by 1.01.

Abstract

The invention relates to the technical field of organic fertilizers, in particular to a preparation method and an application method of an organic fertilizer for ecological saline-alkali land improvement. The preparation method comprises the following steps: mixing and uniformly stirring fermented manure, an improving material and a medium and trace element additive according to a weight ratio of(85-90):(8-14):(1-2), then adding an organic aqueous hydrolyzed polymaleic anhydride solution with the concentration of 1-2%, and adjusting the pH value to 3-5 to obtain the organic fertilizer for ecological improvement. According to the preparation method, the specific steps are as follows: mixing chicken manure, pig manure and cattle manure according to a weight ratio, adding crushed straw, piling, adding a fermenting agent, and fermenting to obtain the fermented manure; then adding the improving material and a medium and trace element additive, mixing and uniformly stirring, then adding theorganic aqueous hydrolyzed polymaleic anhydride solution, and adjusting the pH value to obtain the organic fertilizer for ecological improvement. After application of the organic fertilizer, the contents of medium and trace elements and organic nutrients, such as humic acid, in a saline-alkali land can be increased, the soil nutrient reserve is increased, old organic matters are updated and activated, the total salt content and the pH value of the saline-alkali land are reduced, and the soil quality is improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for preparing and applying an organic fertilizer for ecologically improving saline-alkali land. Background technique [0002] Since there are also a large number of saline-alkali lands in some coastal and inland areas of our country, the salinization of the soil is likely to cause the consolidation and precipitation of nutrients in the soil, which are not easy to be used by crops, resulting in a low fertilizer utilization rate, and the salinization of the soil is also not conducive to The growth and development of crops affect the yield of crops. [0003] With the continuous development of coastal beaches, many difficulties have been encountered in the improvement and utilization of saline-alkali land. In order to make full use of coastal tidal land, people have adopted various methods such as ditches to reduce water and drain salt, inject fresh water to pre...
