Planting method of torreya grandis

Abstract

The invention provides a planting method of torreya grandis. The method comprises four steps of accelerating germination, grow seedlings, transplanting and grafting, wherein in the accelerating germination stage, a two-layered greenhouse is used; an inner-layer plastic film of the two-layered greenhouse is a two-layered film; a plurality of air cavities are formed in the middle of the two-layered film; the two-layered film is aerated or deflated according to the temperature difference between day and night, so that the temperature in the greenhouse is adjusted. A pit 20 cm in depth is excavated in the greenhouse; a first isolation net layer is paved at the bottom of the pit; torreya grandis seeds are piled on the first isolation net layer; a second isolation net layer is paved on the torreya grandis seed layer; a sandy soil layer is paved on the second isolation net layer. By the planting method of torreya grandis provided by the invention, manual temperature control is performed for half a month in December, the sprouting rate in the next January can be 60 percent, and can be 80 percent in next February; two sunshade nets are placed in the pit, so that ventilation is ensured, and the covering soil layer and the torreya grandis seed layer can be taken away conveniently; the process is simple; time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of planting Chinese torreya, in particular to a planting method of Chinese torreya. Background technique [0002] The torreya fruit is rich in nutrition, has a mellow flavor, and has health care, medicinal value, and comprehensive development and utilization value. Torreya torreya is generally used after frying. Torreya torreya seeds are fried and crispy and delicious. The output of Chinese torreya in the market is not high, mainly because the cultivation of Chinese torreya has not yet reached industrialization. [0003] The torreya tree grows slowly, has low survival rate, late fruiting, large investment and late return from the germination of the torreya species to the mature fruit, thereby restricting the large-scale development of the fine variety of torreya. Torreya torreya is an evergreen tree, suitable for growing in a mild, humid, foggy, sunny ecological environment, and is a medium-light-loving pla...
