Embodiment 1

[0033] 1 Test materials and methods

[0034] 1.1 A kind of anti-compaction soil conditioner, comprises the component of following weight:

[0035] 60 parts of bacteria residue, 2 parts of water retaining agent, 5 parts of urea, 15 parts of humic acid, 5 parts of biochemical potassium fulvic acid, 10 parts of bentonite, 0.95 parts of trace elements, 2 parts of phosphoric acid, 0.05 parts of root powder.

[0036] 1.2 Basic properties of the tested soil

[0037] The soil used for the test was taken from the Bohai granary test field in Tanzhuangzi Village, Liubao Town, Wudi County, Binzhou City, Shandong Province. The soil in this area is heavy in texture, low in organic matter, nitrogen, and phosphorus, poor in air permeability, and easily compacted. The physical and chemical properties of the soil are listed in Table 1.

Abstract

The invention relates to an anti-hardening soil improvement agent and a preparation method thereof. The anti-hardening soil improvement agent is prepared from the following components in parts by weight: 0 to 60 parts of cow dung, 0 to 60 parts of microbial fungus residue, 0 to 60 parts of gypsum powder, 0 to 10 parts of urea, 0 to 30 parts of bentonite, 5 to 30 parts of humic acid, 5 to 30 partsof biochemical potassium fulvate, 1 to 5 parts of water retention agent, 0 to 2 parts of pyroligneous liquor, 0 to 2 parts of phosphoric acid, 0.1 to 0.5 part of ferrous sulfate, 0.1 to 0.5 part of copper sulfate, 0.1 to 0.5 part of manganese sulfate, 0.1 to 0.5 part of zinc sulfate, 0.1 to 0.5 part of sodium borate, 0.1 to 0.5 part of ammonium molybdate and 0.02 to 0.1 part of rooting powder. Thespecific weight and the volumetric weight of soil can be effectively decreased; the porosity is improved; the organic content of the soil is increased; the quantity and the stability of water-stablemacro aggregates of the soil are improved; physical property of the soil is ameliorated; the effects of nutrient slow release, water retention and fertility preservation are achieved, and the anti-hardening soil improvement agent has obvious effects on both the nutrient activation of the soil and the yield increment of a crop.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an anti-compaction soil improver and a preparation method thereof. Background technique [0002] In recent years, the degradation of soil quality due to natural and human factors has been serious. The soil texture is sticky, with low organic matter, nitrogen and phosphorus content, poor air permeability, and easy to harden. With the increase of population and the increasing demand for food, unreasonable use of cultivated land, unrestrained use of chemical fertilizers and pesticides, and long-term flood irrigation not only destroy the aggregate structure of the soil itself, but also aggravate soil compaction, and cause soil salinization. , reducing crop yields. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides an anti-compaction soil improver, which can not only effectively reduce soil spe...
