Embodiment Construction

[0018] The following uses the selenium-enriched soil special for yew to cultivate yew:

[0019] 1. Seedling selection: Choose seedlings that are 3 to 5 years old, have thick diameters, lush leaves, and well-developed root systems.

[0020] 2. Time for potting: from the dormant period of seedlings at the end of the month to before the lateral buds expand in early March of the following year. It should be planted on cloudy days and when the soil is moist.

[0021] 3. The new basin should be soaked for 1-2 days before use to remove dryness and alkalinity; the old basin can be used after cleaning.

[0022] 4. Selenium-enriched soil configuration: It is composed of perlite, vermiculite powder, peat soil, sandy soil, organic fertilizer, etc., which are fully and evenly stirred, and then sterilized with carbendazim.

[0023] A. Drainage layer: Put a layer of 1-4cm thick broken tiles or coarse sand, cinder, etc. on the bottom of the basin to increase air permeability and drainage an...

Abstract

The invention discloses seslenium-rich soil special for taxus chinensis and a taxus chinensis cultivation method. The soil comprises 10% of perlite, 5% of vermiculite powder, 10% of peat soil, 50% of sandy soil and 25% of organic fertilizer. The selenium-rich soil is of a granular or cloddy structure. The volume weight of the selenium-rich soil is 1.34g / cm<3>, the porosity is 48%-64%, and the selenium-rich soil is suitable for early-phase and medium-phase growth of taxus chinensis seedlings. The selenium-rich soil special for the taxus chinensis has the advantages of being moderately soft in soil texture, moisture-holding, breathable, appropriate in fertility, constant in temperature, prone to store water and the like. By means of implementation of the taxus chinensis cultivation method, the survival rate can reach over 90%.

Description

technical field [0001] The invention relates to a plant cultivation technique, in particular to a special selenium-enriched soil for cultivating yew and a yew cultivation method using the selenium-enriched soil. Background technique [0002] Because the anticancer drug paclitaxel can be extracted from the bark and branches of the yew, the native yew has been felled in large quantities, and the yew grows slowly under natural conditions and has poor regeneration ability, which made the yew once endangered. In order to protect the wild resources of yew and at the same time obtain the anticancer drug paclitaxel, it is necessary to artificially cultivate yew. Under the existing technical conditions, artificial planting is still a very important way, but to plant and cultivate yew Therefore, the planting soil of yew needs to be carefully studied, because the soil is the growth basis of yew, and the speed of yew root growth and the quality of the tree are closely related to the qua...
