Problems solved by technology

However, due to the slow early growth of masson pine seedlings, using masson pine seedlings to cultivate rootstocks generally requires more than 2 years to meet the grafting requirements. The relationship between the affinity between scions, grafting on different stocks will have a certain impact on the survival rate of grafting and the growth of grafted seedlings to a certain extent

Embodiment 1

[0026] Select masson pine tissue culture seedlings that grow robustly, grow well, and have no pests and diseases, and have been cultivated for 4 months, and transplant them into seedling cups with a size of 40 cm×45 cm, which are equipped with substrate and mixed with fertilizer, and then cultivated according to conventional seedlings. After one month, when the seedlings resume growth and take out new ones, they will be used as rootstocks for later use. The substrate used in the seedling cup is made of pine forest topsoil, fermented pine bark and pumice as raw materials, and is obtained by mixing the pine forest topsoil, fermented pine bark and pumice at a volume ratio of 35:35:30; the fertilizer mixed in the substrate It is 8N-30P-20K-7Mg slow and controlled release fertilizer, the amount of fertilizer is per m 3 The substrate uses 0.8 kg of 8N-30P-20K-7Mg slow-release fertilizer.

Abstract

The invention discloses a grafting method taking masson pine tissue culture seedlings as stocks. The grafting method comprises processes of stock cultivation, scion preparation, seedling grafting and post-grafting management and protection; by taking the masson pine tissue culture seedlings cultivated for 4 to 6 months as the stocks and collecting bud sticks germinating on stock plants as scions, grafting is performed by adopting a split grafting method in December to January or in March to April; grafted seedlings are cultivated under the conditions of suitable light and humidity, and water and fertilizer management and pest control are performed by a conventional method. According to the grafting method disclosed by the invention, the masson pine tissue culture seedlings with developed roots, vigorous metabolism and rapid growth are cultivated through a tissue culture technological means to serve as the stocks, therefore not only can the seedling period of the stocks be shortened and the grafting survival percentage be increased but also the genetic gain of an excellent variety is ensured; adverse effects brought by the fact that heterogeneous-stock grafting is performed by taking slash pines as the stocks widely in masson pine grafting in production at present are effectively avoided, and the working effect of masson pine tissue culture stocks is greatly promoted; the grafting method has a broad application prospect, and has better economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of asexual rapid propagation, and relates to a grafting method using masson pine tissue cultured seedlings as stock. Background technique [0002] Masson pine is the main native afforestation tree species in southern my country. It has a wide distribution range and ranks first in the cultivation area. It has strong adaptability to climate and environment. It is widely used in the fields of building materials, papermaking, chemical industry and medicine. It is not only an excellent building material , is also an excellent raw material for papermaking and man-made fiberboard, and can also be used to produce chemical products such as rosin and turpentine. Therefore, masson pine is not only an excellent timber tree species, but also an important economic tree species, which plays a pivotal role in my country's national economic construction. [0003] Since the systematic study of Pine masson in the "Sixth Five-Y...
