Problems solved by technology

[0005] The existing soil loosening device is convenient for loosening the soil, easy to use, easy to operate, and can reduce labor intensity, but this soil loosening device can only achieve short-term soil loosening effect, and it needs to fertilize the soil in addition. When chemical phosphate fertilizers are applied on the soil surface, it will still cause secondary compaction of the soil

preparation example 1-3

[0040] In Preparation Example 1-3, furfural residues were selected from the furfural residues with the article number 09 sold by Jinan Junda Chemical Technology Co., Ltd., and the mushroom residues were selected from the mushroom residues with article numbers 11221112 sold by Dezhou Xinshen Trading Co., Ltd. The lactic acid bacteria with the item number 037 sold by Shandong Junle Biotechnology Co., Ltd. were selected from the yeast with the item number 025 sold by Cangzhou Xindadi Biotechnology Co., Ltd.

preparation example 1

[0041] Preparation Example 1: Mix 6kg of livestock manure, 2kg of potassium mineral powder, 8kg of activated phosphate rock powder, 4kg of sunflower straw, 3kg of furfural residue and 2kg of mushroom residue, and add lactic acid bacteria, yeast and water according to the ratio of 1:1:2. The mass ratio of the bacteria liquid made by mixing the bacteria liquid and the total mass of the dried fertilizer is 1:800, covered with plastic film, and when the center temperature of the fertilizer is 45 °C, the fertilizer is mixed for 3 times. , and air-dried to a moisture content of 30%.

preparation example 2

[0042] Preparation Example 2: Mix 8kg livestock manure, 3kg potassium mineral powder, 10kg activated phosphate rock powder, 6kg sunflower straw, 4kg furfural residue and 3kg mushroom residue, add lactic acid bacteria, yeast and water according to the ratio of 1:1:2.5. The mass ratio of the bacterial liquid made by mixing the bacterial liquid and the total mass of the dried fertilizer is 1:1100, covered with plastic film, and when the center temperature of the fertilizer is 50 °C, the fertilizer is mixed for 3 times. , and air-dried to a moisture content of 35%.

Abstract

The invention discloses a method for soil loosening and deep fertilization of fruit trees. The method for soil loosening and deep fertilization in fruit tree grounds includes the following steps: S1. Punching several nozzle holes with a depth of 0-100cm in a circle around the vertical projection ground of the canopy of the fruit tree; S2, inserting the nozzle into the nozzle hole and fixing it, Pour the compressed gas into the nozzle, release the pressurized air instantly, loosen the soil 1-5 times, 0.2-3s each time, and the pressure of the pressurized air is 0.3-3MPa; S3, add the organic fertilizer suspension into the nozzle, use the compressed air The gas sprays the organic fertilizer suspension into the soil, spraying the liquid 1-10 times, each spraying lasts 0.5-5s, the spraying pressure is 0.5-3MPa, and the volume ratio of the compressed gas to the organic fertilizer suspension is (10-500 ): 1; S4, pull out the nozzle. The soil loosening and deep fertilizing method for fruit trees can loosen soil and fertilize the soil at the same time, keep the soil loose for a long time, improve the air permeability of the soil, the fertilization process does not damage the root system and the fertilization is uniform, and avoids the long-term use of chemical fertilizers. of hardening.

Description

technical field [0001] The invention relates to the technical field of tree planting, in particular to a method for soil loosening and deep fertilization of fruit trees. Background technique [0002] Soil compaction refers to the lack of organic matter and poor structure of the soil surface layer, which is damaged by external factors such as irrigation or rainfall, and the soil material is dispersed. After drying, the soil surface is hardened by cohesion. Soil compaction will cause the root system to be deficient in oxygen, resulting in a decrease in vitality, failure of normal development, weakened cell respiration at the root of the plant, and at the same time, the root system is limited and the root layer becomes shallow, resulting in a decrease in the cold resistance, drought resistance, and disease resistance of crops. [0003] In order to eliminate soil compaction, it is necessary to increase the application amount of organic fertilizer. Commonly used organic fertilize...
