Multi-functional efficient soil conditioner and preparation method and application thereof

Abstract

The invention relates to the field of soil conditioners, in particular to a multi-functional efficient soil conditioner and a preparation method and application thereof. The active ingredients of thesoil conditioner comprise seaweed dregs, a calcium magnesium phosphate fertilizer, polyglutamic acid, chitosan, kieselguhr and a bioremediating inoculant, wherein the bioremediating inoculant is prepared from iron-reducing bacteria, bacilli and photosynthetic bacteria in an active living bacteria count ratio of 5:3:2. The soil conditioner can improve soil properties, can recover the activity of acidified, saline, hardened, aged and continuously cropped soil and also can improve the ability of supplying nutrition to plants, and the effects of high yield and high quality are achieved.

Description

technical field [0001] The invention relates to the field of soil conditioners, in particular to a high-efficiency multifunctional soil conditioner and its preparation method and application. Background technique [0002] Soil is the most basic means of production for human beings and the material basis for human survival. Soil pollution not only directly leads to the reduction of food production, but more importantly, pollutants will affect human health through the food chain, which is extremely harmful to human beings. Soil pollution can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium, and fluorine, etc.; organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3 , 4-benzopyrene and harmful microorganisms brought by urban sewage...

AI Technical Summary

Problems solved by technology

[0006] At this stage, soil improvement mainly uses soil conditioners. At present, most soil conditioners use calcium hydroxide (lime) to adjust acidic soils, and calcium sulfate (gypsum) to adjust alkaline soils. The product has a single function; or humic acid is used. , humic acid is rich in a large amount of organic matter, and can improve the utilization rate of fertilizer nutrients

However, since most of the current production methods of humic acid are raw powder produced by crushing weathered coal, peat, lignite, etc., the effect of active functional groups of humic acid cannot really be displayed, and the effect is not very obvious; soil conditioner products are basically It is a powdery material that is simply mixed, and it cannot meet the requirements of mechanical fertilization under the condition that the simulcasting of seed fertilizers has become popular in a large area.

The above-mentioned problems lead to the low quality of existing soil conditioners, which are difficult to adapt to different crops and soil conditions, cannot effectively improve the utilization rate of fertilizer nutrients and improve soil structure, and cannot be applied mechanically, which increases labor costs.
