Acidified soil conditioner

Abstract

The invention provides acidified soil conditioner. The acidified soil conditioner is prepared from the following components in parts by weight: 52-58 parts of bamboo carbon, 1-5 parts of a microbial agent, 2-4 parts of hydroxymethyl cellulose, 11-15 parts of bentonite, 10-14 parts of manure, 2-6 parts of polypotassium methacrylate, 1-5 parts of nanosilicon dioxide powder, 2-4 parts of a urease inhibitor, 3-5 parts of carbon calcium nitride, 2-4 parts of nano-zinc oxide, and 3-5 parts of alkali accessories. The invention provides the acidified soil conditioner which is safe and effective, has good improvement effect on the acidified soil, and cannot influence the soil after being applied for a long time. The soil conditioner is low in cost, non-hazardous, capable of promoting the agricultural sustainable development and suitable for popularizing and applying in large scale.

Description

Technical field [0001] The invention relates to the technical field of agricultural soil improvement, in particular to an acidified soil amendment. Background technique [0002] my country has a large population base and a small per capita arable land. There is a long-term pressure to ensure food security, and the intensity of soil utilization is much higher than other countries. With the rapid development of economy and society, soil degradation problems such as acidification, salinization, element imbalance, loss and pollution have become increasingly prominent, which severely restricts the development of land productivity. Soil acidification refers to the phenomenon that the increase of H+ concentration in the soil causes the decrease of soil pH under natural and artificial conditions. It is one of the important indicators of land productivity and an important form of soil degradation. [0003] Two types of soil acidity [0004] One is active acid: it is a direct reflection of t...

AI Technical Summary

Problems solved by technology

[0007] 1. Large and concentrated precipitation, strong leaching, and a large loss of alkaline bases such as calcium, magnesium, and potassium are the root causes of soil acidification

[0008] 2. The lack of traditional agricultural measures such as applying lime, burning manure, and applying organic fertilizers makes the imbalance of soil nutrients in cultivated land the main cause of soil acidification

[0009] 3. Long-term large-scale application of chemical fertilizers is an important cause of soil acidification, even long-term application of urea can also cause soil acidification

[0010] Soil acidification accelerates the increase of soil acidity, which will lead to a decrease in soil base saturation, a decrease in the availability of a large number of nutrients, a decrease in the ability of the soil to supply and maintain fertilizers, and a decrease in soil productivity, seriously affecting crop yields and quality, and cause pollution to water resources, has become a focus of common attention in the field of agricultural production and ecological environment protection at home and abroad
