Modifier for acidized bamboo soil and application thereof

Abstract

The invention discloses a modifier for acidized bamboo soil, which comprises the following materials by weight percent: 45-55% of lime nitrogen, 20-30% of biomass carbon, 10-20% of calcium oxide, 5-10% of magnesium oxide and 5-10% of trace elements. The modifier for acidized bamboo soil provided by the invention is prepared by taking the lime nitrogen and biomass carbon as main parts and matching with the trace elements, is capable of repairing and treating the acidized bamboo soil, is capable of preventing and treating soil-borne pest and disease damage and balancing the requirement for the nutrition of the trace elements in bamboo, and has the three functions of 'acid-controlling, pest-treating and nourishing'. The modifier for acidized bamboo soil and the special fertilizer for the bamboo are applied together, so that the acidification of the bamboo soil is thoroughly eliminated, the repairing for the acidized soil is economically and efficiently realized, the soil-borne pest and disease damage is prevented and treated, the soil fertility is quickly increased and the yield and quality of the bamboo are increased.

Description

technical field [0001] The invention relates to the technical field of soil improvement and ecological restoration, in particular to an improver for acidifying bamboo shoot soil. Background technique [0002] High-value characteristic agriculture, such as tea, bamboo shoots, and fruits, plays an important role in the agricultural economy. However, due to long-term large-scale fertilization and high-intensity utilization, the soil acidification degree of high-value agriculture is more serious than that of field crops. According to the soil survey of bamboo shoots, after 5 years of planting bamboo shoots, the pH value of the soil dropped significantly, and after 5 to 10 years, the pH value dropped by nearly 2 units, making the pH between 3 and 4, and the content of exchangeable aluminum increased by 50 times. [0003] The main technical system of the bamboo shoots intensive management model is mainly based on mass fertilization and winter mulching. The fertilization of bamboo ...

Problems solved by technology

[0010] Although there are a lot of studies on the improvement technology of acidified soil and its improvement agent, there is no compound restoration agent for acidified soil improvement, soil acidification-derived soil obstacle restoration and soil-borne disease control, etc. Systematic exploration of different improvement methods for soil quality, crops and acidification causes

At present, the main purpose of acidifying soil improvement is to reduce soil acidity. The application amount of soil amendment per unit area is large, mostly tens of tons per hectare, and the application cost and labor are relatively large. Soil acidification and its derived soil fertility obstacles and soil-borne diseases lack comprehensive control functions; the existing acidified soil improvement has not stopped and controlled the origin of soil acidification, and it can only treat the symptoms but not the root cause
