Embodiment 1

[0017] In late October, when the Schima superba capsules are found to be slightly cracked, it indicates that the seeds are mature, and the seeds should be collected in time, and then put the harvested capsules in the sun to dry, and let them all crack, and the seeds will fall out of the shell. come out. Pack the collected seeds in cloth bags and store them in low-temperature cold storage (the storage temperature is controlled at 3°C); choose flat, convenient drainage, favorable irrigation, deep soil layer, fertile soil, and moist yellow-red soil as the nursery, and before sowing. Turn and rake the nursery once, apply enough base fertilizer, every 667m 2 Apply 2000kg of cake fertilizer and 200kg of compound fertilizer, mix them evenly with the soil, make the seedbed soil loose and meticulous, and spray 1500-2000 times of thiophanate (or 100 times of 55% Dikesong) to disinfect the seedbed soil. Use 4.5-5.5kg / mu of 70% carbofuran evenly on the seedbed to prevent and control unde...

Abstract

The invention discloses a seedling raising method for dendrobium officinale. The method comprises the technologies of carrying out seed collection and seed storage, garden land selection and treatment, seed treatment, sowing, seedling-stage management and fertilization and the like. According to the method, the dendrobium officinale is stored by adopting low-temperature cold stores (the temperature of the stores is controlled to be 3 DEG C), thus, the lowering of breathing intensity of seeds is facilitated, the energy consumption of the seeds can be reduced, and the viability of the seeds is maintained, so that the germination is improved, the problem in the supply and demand of the dendrobium officinale caused by biennial bearing is effectively solved, and the method has important practical significance. According to the method, the germination ratio and survival rate of the seeds can be effectively increased through carrying out disinfecting treatment on seedling beds before sowing, and the lignification of seedlings can be effectively promoted through carrying out top-dressing at the later growth stage, so that the method plays a crucial role in promoting the raising of high-quality seed seedlings.

Description

technical field [0001] The invention relates to a method for growing seedlings of camellia plant seeds, in particular to a method for raising seedlings of dendrobium officinale. Background technique [0002] Schima superba, also known as lotus tree and lotus tree, is an evergreen tree of the family Theaceae. It is a precious broad-leaved tree species in my country, and it is also the main timber tree species in the south of the Yangtze River Basin in China. It is a national second-class protected tree species. The height of the tree is 30m, the diameter at breast height is 1m, and the life span is more than 100 years. It is more common in low mountains and hills, often mixed with evergreen broad-leaved tree species such as Masson pine, Lauraceae, and Fagaceae. The trunk of Schima superba is straight, the crown is dense, the leaves are thick, leathery, fire-resistant, and have strong germination ability. There are many fallen leaves of Schima superba, which can improve the s...
