Problems solved by technology

At present, the commonly used method is to use lime to improve acidic soil, but long-term or large-scale use of lime will cause soil compaction, and also cause imbalance of calcium, magnesium, potassium and other elements in the soil, resulting in crop yield reduction

Embodiment 1

[0029] A conditioner for southern acidic soil improvement and fertilization, comprising a pea root mixture, which is prepared by the following method: spread the base material evenly, with a spreading thickness of 20cm, and spread the pea shoots according to The density of 14 trees per square meter is planted in the base material. After the peas are ripe and harvested, the pea stalks are removed, and the roots of the peas are left in the base material, stirred, aired, and then crushed, sieved, and dried to obtain the ;

[0030] The base material is prepared from the following raw materials in parts by weight: 60 parts of pond sludge with a water content of 30%, 35 parts of rice straw residue, 20 parts of potassium feldspar, and 14 parts of sodium humate.

Embodiment 2

[0032] A conditioner for southern acidic soil improvement and fertilization, comprising pea root mixture, which is prepared by the following method: the base material is evenly spread, and the spread thickness is 30cm, and the flowering period The pea seedlings are planted in the base material at a density of 18 per square meter. After the peas are ripe and harvested (about 4-6 months), the pea stalks are removed, and the pea roots are left in the base material, stirred, and air-dried. Then pulverize, sieve, and dry to get final product;

Abstract

The invention relates to a conditioning agent for improving and fertilizing south acidic soil and a preparation method thereof. The conditioning agent comprises a pea root mixture. The pea root mixture is prepared by the following steps: evenly paving a basic material to form a layer with a thickness of 20 to 30 cm; planting pea seedlings in the basic material, wherein the number of pea seedlings is 14 to 18 on each square meter of the basic material; after matured peas are picked, removing the pea straws, leaving pea roots in the basic material, stirring, drying the mixture in the sun, grinding the mixture, sieving, and drying to obtain the pea root mixture. The basic material is prepared from the following raw materials in parts by weight: 60 to 70 parts of pond sludge with a water content of 30 to 35%, 30 to 35 parts of straw residues, 20 to 25 parts of potash feldspar, and 14 to 16 parts of sodium humate. The provided conditioning agent is used to improve and fertilize south acidic soil, effectively increases the pH of south acidic soil, enhances the fertilizing performance of soil, increases the crop output, and reduces the content of heavy metals in the soil, the preparation technology is simple, the cost is low, and the conditioning agent is easy to popularize commercially.

Description

technical field [0001] The invention belongs to the technical field of soil treatment, and in particular relates to a conditioner for improving and fertilizing acidic soil in southern China and a preparation method thereof. Background technique [0002] The main types of acidic soil are brick red soil, crimson red soil, red soil and yellow red soil, which are distributed in a zonal manner. Affected by soil-forming parent material and soil-forming factors, it has the characteristics of "acid, barren, poisonous, hard and leaky". The south of my country is hot and rainy, and the soil is strongly weathered. Most of the soil is acidic or strongly acidic. When crops are cultivated in acidic soil in the south, the permeability of the plasma membrane in some plants will be destroyed, resulting in the reduction of the absorption of calcium, magnesium, potassium and other elements by crops. , lower agricultural output. However, this type of soil is widely distributed as agricultural ...
