Method of culturing Chinese yew seedlings

Abstract

A method of culturing Chinese yew seedlings comprises the following steps: (1) the construction of a seedling bed: the seedling bed is 0.9 to 0.1m wide, and the length of the seedling bed is determined according to requirement; (2) the selection and the processing of cutting woods: a one-year branch is chosen, the tender part at the top of the branch is cut off, the branch is cut into the cutting woods which are 9 to 15 cm long respectively, (3) the cuttage of the cutting woods: holes are arranged on the seedling bed according to the density of 4cm multiplied by 5cm; (4) the final-period management of the cutting woods: within seven days after the cuttage, the humidity of a plastic greenhouse is kept at more than 90 percent, seven days after the cuttage, the humidity of the plastic greenhouse is kept at between 75 percent and 85 percent, after the cuttage, foliage dressing is carried out on the cutting woods at intervals of 7 to 10 days, (5) the transplant of the cutting woods: a ditch which is 10m multiplied by 1.2m multiplied by 0.3m is arranged in the north-south direction, 50kg/mu of calcium magnesium phosphate and 250kg/mu of organic fertilizer are spread on the ditch, so that the seedling bed is formed, after 200 to 250 days of culture in the plastic greenhouse, the cutting woods are transplanted in the seedling bed 50 cm deep according to the row spacing of 10cm multiplied by 20cm, after the transplant, the cutting woods are watered for one time until water flows out of the seedling bed; and (6 ) the management after the transplant of the cutting woods: one month after the transplant of the cutting woods, nitrogen fertilizer can be applied, and the nitrogen fertilizer is applied once every two months afterwards, so that the survival rate of the Chinese yew seedlings is improved.

Description

1. Technical field [0001] The invention relates to a method for cultivating yew seedlings, in particular to a method for cultivating yew seedlings suitable for large-scale nurseries. 2. Background technology [0002] Paclitaxel can be extracted from yew. Taxol is an internationally recognized anti-cancer and anti-cancer drug. At the same time, yew is a national first-class protected tree species, because the red beans of yew are like the acacia beans in the south. They are red on the outside and bright on the inside. People's lovesickness, so it is widely loved in our country, so yew is an important forest tree species, yew can be used as a medicinal variety, and can also be used as a greening variety, because the biological characteristics of yew have high requirements on the ecological environment , the main root is not obvious, the lateral roots are well developed, the branches and leaves are lush, the germination is strong, the cold resistance can withstand the low tempe...

Problems solved by technology

[0002] Paclitaxel can be extracted from yew. Taxol is an internationally recognized anti-cancer and anti-cancer drug. At the same time, yew is a national first-class protected tree species, because the red beans of yew are like the acacia beans in the south. They are red on the outside and bright on the inside. People's lovesickness, so it is widely loved in our country, so yew is an important forest tree species, yew can be used as a medicinal variety, and can also be used as a greening variety, because the biological characteristics of yew have high requirements on the ecological environment , the main root is not obvious, the lateral roots are well developed, the branches and leaves are lush, the germination is strong, the cold resistance can withstand the low temperature of -25 ℃; it is suitable for the average altitude of more than 800 meters, the temperature difference between day and night is 7 ℃, and the annual average temperature is only 17 ℃. , Growing in areas with high climate humidity in spring and summer, the soil pH value is required to be between 5.5 and 7.0, and there is no method for cultivating yew seedlings
