Embodiment 1

[0029] The invention discloses a method for raising seedlings of masson pine tissue-cultured seedlings with short branches and short spikes. A 70-hole seedling tray with a hole size of 6 cm x 8 cm and serrated holes on the side of the hole is selected as a container for cutting seedlings. Mix the fermented pine bark, coconut bran, yellow heart soil, and pumice in a volume ratio=2:2:4:2 to obtain a seedling-raising substrate, put the seedling-raising substrate into a non-woven fabric seedling-raising bag with a size of 8cm×9cm, and then place the In the seedling-raising tray, then drench the installed seedling-raising matrix with water, and use a mixture of volume concentration 0.1% carbendazim + volume concentration 0.5% potassium permanganate to sterilize the seedling-raising matrix for later use. When cutting, the seedling-raising matrix in the seedling-raising bag The water content is controlled at 65%.

Abstract

The invention discloses a twig and short shoot cutting seedling raising method for pinus massoniana tissue culture seedlings. The method includes the working procedures of selecting a container, preparing a matrix, collecting cutting shoots, treating the cutting shoots, conducting cuttage and managing a nursery; the suitable seedling raising container is selected, after the matrix is prepared according to a certain ratio and disinfected through a disinfecting method, juvenile-form twigs are collected to serve as the cutting shoots to be eluted and disinfected, after the cutting shoots are treated with a root growth promoting agent, cuttage is directly carried out on the cutting shoots, control over light, temperature, water and fertilizer conditions is enhanced in the period, the cutting shoots take roots about a month later, the rooting rate reaches 98% or above, and the survival rate reaches 97% or above. The pinus massoniana tissue culture seedlings serve as cutting shoot stock plants, the problems that the tissue culture subculture period is long, seedling raising cost is high are solved, the propagation rate is large, the number of qualified juvenile-form twigs for cottage is large, cutting rooting is easy, the effect is remarkable, and the seedling raising method has good economic benefits, social benefits and ecological benefits.

Description

Technical field [0001] The present invention is a plant reproduction technology field, involving organizational cultivation of seedlings, especially a partaroon pine group to cultivate seedlings and tender branches and short spikes. Background technique [0002] Mattarous (Mattatsua ( PinusMassoniana Lamb.) It is the main afforestation tree species in the south of my country. Due to the dual -use characteristics of fat, comprehensive utilization value is high, and the promotion prospects are broad.In recent years, with the increasing demand for life, the shortage of wood resources, and the increasing renewable resources such as wood resources, and the increasing depletion of the non -renewable resources, the sustainable development of ecology, economy and society has attracted more and more social attention.Based on the problems of ecological safety, resource safety and social safety in my country, Mawei Song, as the main industrial material species and biomass energy tree specie...
