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 technical field of cultivation, in particular to a solid substrate for raising seedlings by a citrus container and a preparation method of the solid substrate. The solid substrate raising the seedlings by the citrus container comprises, in weight percent, 25-50% of organic sludge, 25-50% of rice husks, 0-35% of chicken manure and 0-35% of river sand or 30-50% of chicken manure residue, 30-50% of rice husks and 0-35% of river sand which are mixed. Peat is replaced by the aid of industrial and agricultural waste, the ideal solid substrate applicable to raising the seedlings by the citrus container is developed, the components of the substrate are optimized, and the novel solid substrate for raising the seedlings by the citrus container has the advantages that the solid substrate is green, environmentally friendly, low in cost and simple in preparation process, and growth and development of the citrus seedlings are facilitated.

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).
