Taxus chinensis planting method based on seed collecting planting

Abstract

The invention provides a taxus chinensis planting method based on seed collecting planting. The method comprises the steps of S1, planting environment selection: a farmland with the slope smaller than20 degrees, a deep and thick soil layer, a loosened structure, abundant humus and excellent drainage is selected; S2, seed collecting treatment: ripe fruits on a ripe taxus chinensis tree are removed, put into a basin to be rubbed and cleaned until seed coats are broken, the rubbing cleaning is stopped after 50% of a seed kernel is exposed, and the ripe fruits are placed in a shady place to be dried by air for spare use; S3, seedling bed preparation: pits are dug, the pit depth is 25-35 mm, the pit diameter is 35-45 mm, and the spacing between the adjacent pits is 2.0-2.5 m; S4, planting: a greenhouse is constructed, bunch planting is conducted on the seeds to plant the seeds in the dug pits, the seeds are covered with 1-2 cm of fine earth, thorough watering is conducted, an agriculturalmembrane covers the seeds, the four sides of the agricultural membrane are tightly pressed by mud, zinc phosphide is prepared into a toxic bait to prevent rat plague; S5, young seedling transplanting:when small seedlings grow to the state with 3-4 leaves, transplanting is conducted according to the plant spacing of 15-20 cm and the row spacing of 25-30 cm; S6, nursing management; S7, transplanting forestation: when the young seedlings grow to the height of 30-50 cm, transplanting forestation is conducted in spring; S8, forestry nursing.

Description

technical field [0001] The invention relates to the technical field of yew planting, in particular to a yew planting method based on seed collection and planting. Background technique [0002] Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is recognized as an endangered natural and rare anti-cancer plant in the world. It is an ancient tree species left over from Quaternary glaciers. It has been on the earth for 2.5 million years. Due to the slow growth rate and poor regeneration ability of yew under natural conditions, there has not been a large-scale yew raw material forest base in the world for a long time. Used as medicine, it contains paclitaxel, paclitaxel, and diterpenoids. It has anti-cancer functions, and has the effect of inhibiting diabetes and treating heart disease. Because the growth cycle of yew is generally 8 to 10 years, and because yew The survival rate of saplings is low, resulting in poor economic benefits...
