Introduction
Natural rubber is an important agricultural product and strategic resource of the country. It is a resource-constrained industry and plays an important role in ensuring national strategic security and promoting the development of hot rural areas.
The revitalization of rubber trees is of great significance. Rubber tree seedlings are the basis for the sustainable development of the natural rubber industry. The production cycle of rubber trees is as long as 30 years.
The scientific, standardized and reasonable cultivation and use of seedlings is a basic scientific and technological issue for the high-quality development of the industry and is of great importance to producers, operators, users and managers.
The attention of management departments.
The quality of seeds and seedlings is an important factor affecting the growth of rubber trees. Standardized and standardized production of rubber tree seeds and rubber tree seedlings
The use of rubber trees is conducive to the improvement of the benefits of the natural rubber industry. Therefore, GB/T 17822 Rubber Tree Seedlings consists of two parts.
--- Part 1.Seeds.
--- Part 2.Seedlings.
One of the main uses of rubber tree seeds is to cultivate rubber tree rootstock seedlings. With the continuous development of rubber tree seed production and inspection technology,
First, based on the differences in the maturity and development stages of rubber tree seeds, their intolerance to dehydration and storage, as well as the quality of seed harvesting, storage, and transportation environment,
Given the importance of the environment to the cultivation and use of rootstock seedlings, it is necessary to develop this document.
This document provides technical guidance for the industry in terms of rubber tree seed cultivation, rootstock seedlings, etc., aiming to promote the scientific and legal cultivation of rubber tree seeds in my country.
Management and standardized use can improve the efficiency of rubber tree seedling cultivation and seedling quality.
