Problems solved by technology

Although the container seedling-growing substrate of the present invention can completely replace the new solid substrate of peat-type or sawdust-type substrate, the nutrient status that plants can absorb is uncertain, which is not conducive to the precise regulation of nutrient moisture, and its nutrient content cannot fully meet Seedling needs, can not well overcome the limiting factors of citrus growth and development

Embodiment 1

[0038] Mix 35% organic sludge, 35% chaff, 25% chicken manure, and 5% river sand, and dry at 120°C to form a solid mixture with a total pore space ratio of 52%, and then crush it to a solid The particle size of the mixture is 2.5 mm or less, and the particles with a particle size of 2.5 mm or less are screened, and the solid mixture with a particle size greater than 2.5 mm is continuously broken until the particle size is less than 2.5 mm to form the solid for citrus container seedling cultivation. matrix.

Embodiment 2

[0040] Fully mix 50% organic sludge and 50% chaff, dry at 200°C to form a solid mixture with a total pore space ratio of 60%, and then crush until the particle size of the solid mixture is 2.5 mm or less , screening particles with a particle size smaller than or equal to 2.5mm, and continuing to crush the solid mixture with a particle size larger than 2.5mm to a particle size smaller than 2.5mm, forming the solid matrix for citrus container seedling cultivation.

Embodiment 3

[0042] 25% organic sludge, 25% chaff, 30% chicken manure, 20% river sand are fully stirred and mixed, dried at 230°C to form a solid mixture with a total pore space ratio of 85%, and then crushed to a solid The particle size of the mixture is 2.5 mm or less, and the particles with a particle size of 2.5 mm or less are screened, and the solid mixture with a particle size greater than 2.5 mm is continuously broken until the particle size is less than 2.5 mm to form the solid for citrus container seedling cultivation. matrix.

Abstract

The invention belongs to the field of cultivation technology, and in particular relates to a solid substrate for citrus container seedling cultivation and a preparation method thereof. The solid substrate formula for container seedling cultivation of citrus is made of 25-50% organic sludge, 25-50% chaff, 0-35% chicken manure, 0-35% river sand, or 30-50% It is made by mixing 50% chicken dung, 30-50% chaff and 0-30% river sand. The invention uses industrial and agricultural waste to replace peat, develops a solid substrate suitable for citrus container seedling cultivation, optimizes the composition of the substrate, and proposes an ideal solid substrate for citrus container seedling cultivation. The novel solid substrate used for citrus container seedling cultivation has the advantages of environmental protection, low cost, simple preparation process and favorable growth and development of citrus seedlings.

Description

technical field [0001] The invention belongs to the field of cultivation technology, and in particular relates to a solid substrate for citrus container seedling cultivation and a preparation method thereof. Background technique [0002] Citrus is the world's largest fruit, with a total output of about 105 million tons in 2005, accounting for about 22% of the world's total fruit output. The world's annual trade volume of citrus products (including fresh fruit, orange juice and canned orange petals, etc.) is about 6.5 billion US dollars, second only to corn and wheat, and is the third largest traded agricultural product. my country is one of the important origin centers of citrus in the world. In recent years, the citrus industry has developed rapidly. In 2007, the area of ​​citrus in my country reached more than 20 million mu, ranking first in the world; the output reached more than 17 million tons, ranking second in the world , second only to Brazil (23.99 million tons).
