Problems solved by technology

[0002] In recent years, due to the improper application methods, habits and dosage of chemical fertilizers, the physical and chemical properties of the soil have deteriorated, the fertility of the soil has decreased year by year, and soil compaction and acidification have become more serious problems.
Among them, soil compaction will greatly reduce the ability of the soil to absorb water, oxygen and absorb nutrients, which will cause the poor development of the root system of the crop and seriously affect the growth and development of the crop.

preparation example Construction

[0020] On the other hand, the embodiment of the present invention proposes a preparation method of the aforementioned soil conditioner. Concretely comprise following preparation steps:

[0021]Firstly, waste glass is pulverized and ground into glass powder with a particle size of 1mm-2mm, and then the glass powder is fired at 700°C-850°C for 20min-40min to obtain a first sintered product. The crushed and ground glass powder can be heated more evenly during the sintering process, and the particle size is more consistent with the range of the coarse sand particle size in the soil, which is more suitable for application in the soil. When the particle size of the glass powder is large, on the one hand, it is heated unevenly, especially the sintering degree of the center of the glass particle is lower than that of the edge, so that the opening rate and number of pores of the glass powder are small, and the water absorption and storage Poor ability. When the particle size of the g...

Embodiment 1

[0027] The purpose of this embodiment is to provide a soil conditioner, which includes the following raw materials: 50g of glass and 200g of meal waste.

[0028] The soil conditioner provided in this embodiment can be prepared through the following steps:

[0029] The glass is pulverized to make glass powder with a particle size of 1 mm-2 mm, and then the glass powder is fired to obtain a first sintered product, the sintering temperature is 700° C., and the sintering time is 20 minutes. Then, the food waste is dehydrated, crushed, and fired to obtain a second sintered product, and the sintering temperature is 100° C., and the sintering time is 1 h. Finally, the first sintered product and the second sintered product were uniformly mixed to obtain a mixture, and the mixture was fired at 450° C. for 2 hours to obtain the soil conditioner.

Embodiment 2

[0031] The purpose of this embodiment is to provide a soil conditioner, including the following raw materials: glass 100g, meal waste 300g and humic acid 15g.

[0032] The soil conditioner provided in this embodiment can be prepared through the following steps:

[0033] The glass is pulverized to make glass powder with a particle size of 1mm-2mm, and then the glass powder is fired to obtain the first sintered product. The sintering temperature is 850° C. and the sintering time is 40 minutes. Then, the food waste is dehydrated, crushed, and fired to obtain a second sintered product, and the sintering temperature is 150° C., and the sintering time is 2 hours. Finally, the humic acid, the first sintered product and the second sintered product were uniformly mixed to obtain a mixture, and the mixture was fired at 550° C. for 4 hours to obtain the soil conditioner.

Abstract

The invention provides a soil conditioner, and a preparation method and a use method thereof, and relates to the technical field of soil improvement. According to the soil conditioner, glass and food waste are sintered and mixed to prepare a material with a compact porous structure, and when the soil conditioner is applied to soil, not only can moisture be effectively locked, but also the air permeability of the soil can be enhanced, so that the problem of soil hardening is effectively solved. In addition, the invention further provides the preparation method of the soil conditioner, the soil conditioner with the good improvement effect can be simply and rapidly prepared through the method, operability is high, intelligent automatic production is easy to achieve, and practicability is high. Besides, the invention further provides the use method of the soil conditioner, namely, the soil conditioner and an organic fertilizer are mixed and applied according to the proportion of (0.3-0.8): 1, so that the utilization rate of the soil conditioner can be increased, the situation of incompatibility of the mixing proportion can be avoided, and the problem of soil hardening can be better solved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improver, a preparation method and usage thereof. Background technique [0002] In recent years, due to the improper application methods, habits and dosage of chemical fertilizers, the physical and chemical properties of the soil have deteriorated, the fertility of the soil has decreased year by year, soil compaction and acidification have become more serious problems. Among them, soil compaction will greatly reduce the ability of the soil to absorb water, oxygen and absorb nutrients, thus making the root system of crops poorly developed and seriously affecting the growth and development of crops. Therefore, it is particularly important to propose a improver for improving soil compaction. Contents of the invention [0003] The object of the present invention is to provide a soil improver, which has a good water retention effect and can effectively solve the pro...
