Embodiment 1

[0018] Embodiment 1, 10 parts of plant straw powder, 1 part of humic acid, 1 part of acrylate water retaining agent, 1 part of urea, 1 part of gypsum, 1 part of citric acid, 0.1 part of EM bacteria, 1 part of sodium ion adsorbent (by mass Parts, the same below), fully mix in the mixer, then add 0.3 to 1 times of the total amount of raw materials water-soluble binder, and granulate in the granulator (particle size is 1 to 3mm). Straw powder is any one of food crops, economic crops, plant stems and leaves, bark, and forest and grass crushed products (the same below).

Embodiment 2

[0019] Example 2: Mix 10 parts of plant straw powder, 4 parts of humic acid, 2 parts of acrylamide water-retaining agent, 2 parts of urea, 5 parts of gypsum, 10 parts of wood acid, 5 parts of EM bacteria, and 4 parts of sodium ion adsorbent. Mix well in the machine, then add 0.3 to 1 times the water-soluble binder of the total amount of raw materials, and granulate in a granulator (particle size is 1 to 3mm).

Embodiment 3

[0020] Example 3: 10 parts of plant straw powder, 8 parts of humic acid, 4 parts of starch-grafted acrylic acid water-retaining agent, 4 parts of urea, 8 parts of gypsum, 8 parts of oxalic acid, 4 parts of EM bacteria, and 8 parts of sodium ion adsorbent were used in Mix well in a mixer, then add 0.3 to 1 times of the total amount of raw materials as a water-soluble binder, and granulate in a granulator (particle size is 1 to 3mm).

Abstract

The invention provides a high activity biological water retention alkali oil modifying agent, which is prepared through fully and evenly mixing vegetable stem powder, humic acid, water-loss reducer, carbamide, gypsum, high activity biological agent, sodium ion adsorbent and acid according to certain proportion, adding binding agent which is 0.3-1time of the whole weight of raw material, and granulating in pelleting machine. The high activity biological water retention alkaline earth modifying agent which is prepared by the invention can effectively improve soil aggregate structure, increases the water holding property of soil, can effectively dissociate and absorb metal ion, reduces the components of soil soluble salt, increases soil organic matter and nutrition, and has extremely significant soil modifying effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and relates to a soil improver, in particular to a highly active biological water-retaining soil improver and a preparation method thereof. The highly active biological water-retaining soil improver of the invention is mainly used for the improvement of saline-alkali soil. Background technique [0002] In my country, the area of ​​saline-alkali soil is large, which has a great impact on the production and development of agriculture and forestry. Chinese patent 00100436 discloses a saline-alkali soil improver and its preparation method; Chinese patent 200510012366.1 discloses an alkaline soil improver, which is compounded with gypsum, straw and urea in a certain proportion. Chinese patent 200610146026.2 discloses a special nutrient improvement agent for saline-alkali land and its processing method. % straw powder, 10% to 20% furfural slag and 10% to 12% organic fertilizer; Chine...
