Problems solved by technology

Therefore, citrus seedlings bred in the open field usually have only a few natural mycorrhizae, which seriously weakens the beneficial contribution of mycorrhizal symbionts to citrus nutrient uptake and utilization and disease resistance.

Embodiment 1

[0027] The preparation of embodiment 1 citrus container seedling cultivation nutrient soil

[0028] 1. Vermicompost preparation

[0029] Mix cow dung and rice husks evenly according to the volume ratio of 5:1, adjust the water content to 50%-60%, then build a heap with a length of 2 m, a width of 1 m, and a height of 0.4 m and place it in a greenhouse for natural fermentation for 1 month. Keep the humidity, turn it over several times, inoculate about 3,000 earthworms per square meter of cow dung after full fermentation, and cover it with 3~5cm thick cow dung. During daily management, water should be frequently sprinkled to keep the relative humidity of cow dung at about 70%. , and the temperature is maintained at 15-30°C. When earthworms drill into the surface of cow dung, new cow dung should be added in time. The cow dung becomes vermicompost after being fully fed by earthworms, and then the earthworms are separated by scraping the skin and removing the heart to obtain vermi...

Abstract

The invention discloses a method for preparing nutrient soil from earthworm cast for breeding of citrus container mycorrhizal seedlings. The method comprises steps as follows: a, preparation of the earthworm cast compounded seedling breeding nutrient soil: the earthworm cast compounded seedling breeding nutrient soil is prepared from components including the earthworm cast, turf, rice husks and orangery soil in the volume ratio being (15%-45%):(15%-45%):20%:20%, and the components are crushed and then are compounded and mixed evenly in the ratio; b, germination acceleration of trifoliate orange seeds; c, sterilization of seedling breeding bags; d, seeding; e, conventional stock nursery management performed on the seedling breeding bags after seeding. With the adoption of the design, the use amount of the turf for citrus container seedling breeding can be effectively reduced, the production cost of the citrus container seedlings can be reduced, resource utilization of poultry and livestock manure can be realized, through inoculation with an AMF highly-effective bacterial agent, growth of the seedlings is promoted, resistance of the seedlings is improved, and the quality of the seedlings for sell is improved.

Description

technical field [0001] The invention relates to the cultivation technology of citrus seedlings, in particular to a method for cultivating citrus container mycorrhizal seedlings by using vermicompost to make nutrient soil. Background technique [0002] Seedling raising is an important link in citrus production, and the quality of seedlings is directly related to the growth and development of plants, fruit yield and quality. [0003] At present, citrus rootstock seedlings are usually propagated by seeds. Traditional open-field seedling cultivation facilities have poor environmental control capabilities, low and slow emergence rates, and are easily infected by diseases and insect pests. Container seedlings can breed high-quality seedlings. widely used. [0004] Excellent substrate is the key to cultivating strong container seedlings of citrus. Due to its ideal physical and chemical properties, peat is widely used in container seedling cultivation of forest trees, fruits, veget...
