Abstract

The invention provides a strong root matrix for cutting seedlings and a cutting method and relates to the technical field of cutting seedling growing. The strong root matrix comprises the following raw materials in parts by weight: 1.5-3 parts of medium loamy soil, 0.6-1.5 parts of vermiculite, 0.6-1.5 parts of perlite, 1.5-2.8 parts of grass peat and 0.05-0.2 part of No. 15 Peters. The strong root matrix and the cutting method provided by the invention have the benefits that during cutting, the seedlings are rooted with fine sand firstly, and then the rooted seedlings are transplanted onto the strong root matrix to grow till the hardened seedlings are transplanted into a field; and by the utilization of the method, not only can the rooting rate of the seedlings be controlled to reach 90.71-95.88 percent, but also the transplanting survival rate can be improved to 89.82-94.70.

Description

technical field

[0001] The invention belongs to the technical field of cutting seedling cultivation, and in particular relates to a root-strengthening matrix of cutting seedlings and a cutting method. Background technique

[0002] Populus tomentosa is a genetic resource submitted to the Food and Agriculture Organization of the United Nations and the Environment Program for review and protection. Its fast growth, wood properties, and excellent resistance are all outstanding among poplar species. It is an important greening tree species in northern my country. It is widely used in afforestation, shelter forest construction, urban and rural greening construction, etc., and has important value for forestry construction and ecological construction.

[0003] Populus tomentosa has a long history of cultivation in the Huanghuaihai River Basin and the North China Plain. Because it is traditionally distributed in areas south of 41° north latitude, conventional propagation is difficult,...
