Embodiment 1

[0024] A method for regulating the soil properties of citrus orchards is to sprinkle 500kg of nutrient material into each mu of soil, till and stir evenly, and after an interval of 5 days, add 20kg of soil improver to each mu of soil, till and stir evenly; in,

[0025] The nutrient material is composed of the following raw materials in parts by weight: 30 parts of brown coal powder, 80 parts of modified bentonite, 20 parts of EDTA-Fe, 12 parts of EDTA-Mg, and 400 parts of traditional Chinese medicine residue;

[0026] The preparation method of the lignite powder is as follows: pulverize the lignite and add a pore-forming agent of 8wt% by weight and stir evenly, then place the stirred mixture in an anoxic environment and burn it for 4 hours at a temperature of 1250° C.; The pore-forming agent is diaminodiphenyl ether;

[0027] The preparation method of the modified bentonite is: preheating the bentonite at 200° C. for 1 minute, and then transferring it to a temperature of 650°...

Embodiment 2

[0030] A method for adjusting the soil properties of citrus orchards is to sprinkle 700kg of nutrient material into each mu of soil, till and stir evenly, and after an interval of 7 days, add 30kg of soil improver to each mu of soil, till and stir evenly; in,

[0031] The nutritional material is composed of the following raw materials in parts by weight: 40 parts of brown coal powder, 90 parts of modified bentonite, 25 parts of EDTA-Fe, 15 parts of EDTA-Mg, and 500 parts of traditional Chinese medicine residue;

[0032] The preparation method of the lignite powder is as follows: pulverize the lignite and add a pore-forming agent of 10 wt% of the lignite and stir evenly, then place the stirred mixture in an anoxic environment and burn it for 6 hours at a temperature of 1300° C.; The pore forming agent is polyimide;

[0033] The preparation method of the modified bentonite is: preheating the bentonite at 220° C. for 2 minutes, and then transferring it to a temperature of 700° C...

Embodiment 3

[0036] A method for adjusting the soil properties of citrus orchards is to sprinkle 600kg of nutrient material into each mu of soil, till it and stir it evenly, and after an interval of 6 days, add 25kg of soil improver to each mu of soil and till it until it is evenly stirred; in,

[0037] The nutritional material is composed of the following raw materials in parts by weight: 35 parts of brown coal powder, 85 parts of modified bentonite, 22 parts of EDTA-Fe, 14 parts of EDTA-Mg, and 450 parts of traditional Chinese medicine residue;

[0038] The preparation method of the lignite powder is as follows: pulverize the lignite, add a pore-forming agent of 9 wt% of the lignite and stir evenly, then place the stirred mixture in an anoxic environment and burn it for 5 hours at a temperature of 1280° C.; The pore-forming agent is a composition composed of diaminodiphenyl ether and polyimide in a mass ratio of 1:2.5;

[0039] The preparation method of the modified bentonite is: prehea...

Abstract

The present invention provides a method for adjusting performance of soil in a citrus orchard, and belongs to the field of citrus plantation. The method comprises the steps of spreading a nutrition material of 500-700 kg per mu to the soil and plowing and stirring the soil uniformly, and after 5-7 days, adding a soil conditioner of 20-30 kg per mu to the soil and plowing and stirring the soil uniformly; wherein the nutrition material is composed of raw materials including, by weight, 30-40 parts of brown coal powder, 80-90 parts of modified bentonite, 20-25 parts of EDTA-Fe, 12-15 parts of EDTA-Mg, and 400-500 parts of traditional Chinese medicine slag. According to the method, the harden soil can be improved, the soil pH value is can be adjusted, heavy metal pollution in the soil can be reduced, and therefore the soil fertilizer can be increased. The method is suitable for large-scale systematic application to increase production and income for farmers.

Description

【Technical field】 [0001] The invention relates to the technical field of citrus planting, in particular to a method for regulating soil properties of citrus orchards. 【Background technique】 [0002] Soil is the unconsolidated layer of the land surface consisting of minerals, organic matter, water, air, and living things that is fertile and capable of growing plants. Citrus has a wide range of adaptability to soil, purple soil, red-yellow soil, sandy beach and tidal flats can grow at a pH value of 4.5-8, with a pH value of 5.5-6.5 being the most suitable. The growth of citrus root system requires higher oxygen content, and the soil texture is loose, the structure is good, the organic matter content is 2% to 3%, and the soil with good drainage is the most suitable. Citrus roots are mainly distributed in the 0.90-meter soil layer, and vary according to irrigation conditions. The vast majority of aerobic active roots are distributed in the top 30 cm of soil. [0003] At prese...
