Hybridization Broussonetia papyrifera seedling growing method

Abstract

The invention belongs to the agriculture plantation technical field, and discloses a hybridization Broussonetia papyrifera seedling growing method comprising the following steps: 1, matrix disinfection: loading the matrix into a seedling growing container, using 75% quality concentration alcohol to disinfect the matrix, using the quality concentration 3% limewash to disinfect the matrix, using a film to cover the matrix for preparation; the matrix is formed by mixing the following raw materials by weight parts: slow release fertilizer 10-15 parts, activation rock phosphate 8-12 parts, medium sand 5-10 parts, husk 5-10 parts, humus soil 3-8 parts, diatomite 3-5 parts, earthworm powder 3-8 parts, rock wool 3-5 parts, chitosan 3-5 parts, and puffed chicken manure 3-5 parts; 2, cutting branch selection and processing; 3, cutting; 4, cutting anaphase management. The seedling growing stock obtained by the method is high in survival rate, and the seed selection breeding Broussonetia papyrifera is suitable to promote and plant in rocky regions in our nation.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for raising seedlings of hybrid mulberry trees. Background technique [0002] The mulberry tree is a unique fiber-containing tree species in my country. It is a special economic forest. Its bast fiber infusion is extremely valuable, and it is resistant to drought and barrenness. It is a more suitable tree species for barren hills and rocky desertification. . The leaves of paper mulberry contain very high protein, about 20-30%, much higher than that of corn, wheat, amino acids, vitamins, and carbohydrates. They are used for livestock feed, and bark and rods are used for papermaking. As the country proposes paper mulberry Priority requirements for poverty alleviation industries. Hybrid mulberry is a fast-growing and high-yield tree species with excellent stress resistance that has been artificially cultivated through genetic improvement. It can mee...

Problems solved by technology

However, the cultivation of hybrid tree seedlings is the bottleneck that inhibits the hybrid tree industry. There are technical factors such as the difficulty of clustering buds and the easy vitrification of seedlings in the tissue culture of hybrid tree. Tissue culture requires high technology and equipment and a large amount of capital investment. Practitioners have high professional and technical requirements, and problems such as low rooting rate of common cuttings limit its application and promotion

[0003] At present, the planting and cultivation of hybrid mulberry trees mainly adopts cuttings to raise seedlings. Due to various reasons, the rooting rate is low and the growth cycle is long, so it is difficult to achieve efficient and rapid large-scale industrial planting and cultivation.
