Method for walnut seedling culture and transplantation

Abstract

The invention discloses a method for walnut seedling culture and transplantation. Through seedling setting with trays, root cutting transplanting and container culture, the growth process and the transplanting process of seedlings do not affect each other. Soil balls which seedling roots take greatly reduce loss of roots in the transplanting process, the transplanting survival rate is improved, the rejuvenation period is shortened, root systems of the cultured seedlings are flourishing, and the standard of grafting on the same year is met. The method is simple to operate, practical, low in cost and consistent in growth vigor, the transplanting survival rate is 95% or above, the seedling growth amount is obvious on the year of transplantation, nearly a half of rootstocks can reach the grafting standard when autumn is up, the seedling culture time is short, and the method is suitable for large-scale reproduction.

Description

technical field [0001] The invention relates to the field of agriculture and forestry cultivation, in particular to a method for growing and transplanting walnut seedlings, in particular to transplanting American hickory seedlings. Background technique [0002] American hickory (Carya illinoinensis Koch), also known as thin-shell hickory and long hickory, belongs to the genus Hickory of Juglandaceae. It is an ecological and economical tree species integrating high-grade dried fruit, landscaping and high-grade wood. American hickory has been introduced to China for more than 110 years, but the introduction and cultivation are mostly sporadic, and industrial production has not been formed. One of the main reasons is that the species are unclear, the supply of good seedlings is tight, and the supporting cultivation techniques are not perfect. With the development and promotion of the American hickory industry, the demand for American hickory seeds continues to expand, and the d...

AI Technical Summary

Problems solved by technology

However, there are still some problems in the sowing and breeding technology of its seedlings. Because American hickory is a tap root system with few fibrous roots, the roots of the seedlings are more vulnerable to damage during the seedling transplanting process, which affects the survival rate of seedlings transplanted and the growth of seedlings in the current year.

At present, there is no complete set of technical regulations for large-scale seedling production, and the quality of seedlings is uneven, which restricts the rapid development of the American pecan industry
