Description

A method for rapid seedling cultivation of teak clones in light substrate plugs

technical field

The invention belongs to the technical field of arbor cultivation and propagation, and in particular relates to a method for rapidly growing seedlings in light-substrate plugs of teak clones.

Background technique

Teak (Tectona grandis L.f.) is a tall tree of the genus Tectona in the family Verbenaceae. It is naturally distributed in southern and central India, northern Thailand, Myanmar and Laos at 9°-26° north latitude and 73°-104° east longitude. It is a famous tropical precious timber tree species, known as the "King of Ten Thousand Woods". Its heartwood is tough and durable, with a dense structure and beautiful texture. Timber. Teak has the characteristics of fast growth, excellent material, wide application and high return on investment. It is widely planted in tropical and subtropical regions. It is one of the four tree species with the largest plantation area in the world, and it is also the afforestation tree species with the highest output value per unit area. .

China has introduced teak cultivation for more than 180 years. Through the research on teak cultivation technology, the promotion and planting scope covers more than 60 counties (cities) in 10 provinces (autonomous regions), with a total area of about 15,000 hm ² . Now, Yunnan and Hainan provinces list teak as the main tree species for afforestation, and more and more private individuals and enterprises use teak for afforestation in Guangdong, Guangxi, Fujian, and Guizhou provinces. However, at present, the development of teak commercial forests in my country is mainly based on seed seedlings and excellent tissue culture clone seedlings. Nutrient bag seedlings are often used as the matrix of yellow core soil, relying on manual bagging, and the labor efficiency of seedling cultivation is low, and each plant weighs 0.50～0.75kg, the transportation cost is high when large-scale afforestation, especially in the afforestation of tropical and subtropical mountainous areas in my country, due to the weight of seedlings in nutrition bags, it is difficult for workers to pick seedlings up the mountain, and the quantity is small and the efficiency is low. However, it usually takes 8 to 12 months to cultivate young seedlings into cut dry seedlings, and the main roots, lateral roots and fibrous roots need to be pruned to raise the seedlings. Slow growth, reduced cold and wind resistance. Therefore, cultivating seedlings with complete and light root system is particularly important to mountain teak afforestation.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a method for rapidly growing seedlings in light-substrate plugs of teak clones. The seedling raising method uses teak rootless tissue culture bottle seedlings as propagation materials, selects light substrate for seedling cultivation (light substrate) and replaces seedling cultivation bags with seedling cultivation trays for rapid seedling cultivation, which saves the cost of seedling cultivation and afforestation, and improves the efficiency of seedling cultivation and afforestation , The weight of each cultivated light-substrate seedling is only 0.15-0.20 kg, which reduces the transportation cost and labor intensity of afforestation workers.
