Embodiment 1

[0015] Embodiment 1, a kind of method A that can efficiently eliminate continuous cropping obstacles

[0016] In other fields, corn is planted to the heading stage, and the above ground is harvested, and the stubble is ploughed with a plough to loosen the stubble from the soil. Use a five-strand manure fork to remove the stubble with soil and the soil with the stubble, and pulverize it with a knife pulverizer for later use. The crushed material is transported to the soil with continuous cropping obstacles, and the dosage is 5000kg / hm 2 , sprinkled on the soil surface, rotary tillage, all rotary tillage and continuous cropping of cucumbers. Under the same conditions of other management, compared with the control, the incidence of seedling stage decreased by 46%, and the yield increased by 23.21%.

Embodiment 2

[0017] Embodiment 2, a kind of method B that can efficiently eliminate continuous cropping obstacles

[0018] In other fields, the wheat is planted to the ear-opening stage, and the living stubble is loosened from the soil by ploughing with a ploughing plough. Use a five-strand manure fork to remove the stubble with soil and the soil with the stubble, and pulverize it with a knife pulverizer for later use. The crushed material is transported to the soil with continuous cropping obstacles, and the dosage is 6000kg / hm 2 , sprinkled on the soil surface, rotary tillage, and planting tomatoes. Under the same conditions of other management, compared with the control, the incidence of seedling stage decreased by 57.6%, and the yield increased by 25.41%.

Embodiment 3

[0019] Embodiment 3, a kind of method C that can efficiently eliminate continuous cropping obstacles

[0020] When sorghum is planted in other fields until the heading stage, the upper part of the ground is harvested first, and the living stubble is loosened from the soil by ploughing with a plough. Use a five-strand manure fork to remove the stubble with soil and the soil with the stubble, and pulverize it with a knife pulverizer for later use. The crushed material is transported to the soil with continuous cropping obstacles, and the dosage is 3200kg / hm 2 , ditching strip Shi, planting American ginseng. Under the same conditions of other management, compared with the control, the incidence of seedling stage decreased by 88.6%, and the yield increased by 35.48%.

Abstract

The invention discloses a method for eliminating successive cropping obstacles by living crop root residues and rhizosphere soil transplantation. 8 living crop root residues and extensive rhizospheresoil are adopted, living crops comprise wheat, corns, sorghums, rice, barley fruits, peanuts, soybeans and ryegrasses, and the extensive rhizosphere soil refers to soil 3cm within the periphery of a root system. The living crop root residues and the extensive rhizosphere soil are prepared into crushed materials, the crushed materials are spread to the surface of continuous cropping soil, rotary tillage or row fertilization or hole fertilization or root dipping is maximally performed, and the crops such as continuous cropping vegetables, melons and fruits, fruit trees, American ginseng roots and yellow ginger normally grow.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a method for eliminating continuous cropping obstacles by transplanting living crop stubble and rhizosphere soil. Background technique [0002] With the heating up of special industrialization, a number of distinctive professional production areas have emerged in various parts of my country, and the original farming system is not suitable for the current agricultural development needs. In particular, the number of farmers engaged in the production of a specific agricultural product has gradually increased. For example, the high-value varieties of facility cultivation include several fruit and vegetable teas, soybeans, American ginseng, Panax notoginseng and turmeric with relatively high economic benefits, thus accelerating the continuous cropping diseases. development of. The continuous cropping obstacle is that when crops of the same species or family are continuously cultivated in t...
