Abstract

The invention discloses a red soil conditioner prepared by compounding earthworm cast with molybdenum fertilizer. The red soil conditioner is mainly composed of, by mass, 40-60 parts of earthworm cast, 25-35 parts of volvaria volvacea residue, 8-12 parts vermiculite and 8-12 parts of corn straw, and a molybdenum source containing 16.00-24.00g of molybdenum element is added into each kg of main components. The conditioner can effectively improve pH value of soil, increase content of organic matter, improve soil structure, lower soil volume weight and increase content of effective molybdenum inthe soil and molybdenum content in plants and is suitable for restoration and conditioning of degenerated red soil and especially suitable for molybdenum-deficient red soil. A preparation method of the conditioner is simple and easy to implement, low in cost, safe and environment friendly.

Description

technical field [0001] The invention relates to the field of soil remediation, in particular to a red soil conditioner composed of vermicompost and molybdenum fertilizer. Background technique [0002] According to statistics, the total area of ​​red soil in southern my country reaches 2.1796 million square kilometers, including 15 provinces (regions), accounting for 1 / 5 of the country's land area; the population is 480 million, accounting for 40% of the country; the cultivated land is 28 million hectares, accounting for 30% of the country %. One-third of the country's arable land provides half of the country's agricultural output value, half of the grain and bears nearly half of the population. However, due to the long-term irrational use of land resources, the ecology and environment of the entire region have been severely damaged, and the problem of soil degradation is extremely serious, including the following aspects: [0003] 1. Soil acidification is serious, and the t...
