[0021] A method for cultivating yew seedlings, comprising the steps of:

[0022] a. Seed treatment: first set up a storage sand tank, the bottom of the sand tank is provided with a plurality of small holes, and the height of the sand tank is 20 cm; Harvest when it is red, soak the harvested seeds in clean water for 1 hour at a temperature of 20°C to 25°C, then rub off the seed coat, wash and dry; then store the seeds in sand ponds, sand ponds There is a hole at the bottom, and the sand pool is 20 cm high. A layer of sand is laid in the sand pool and then a layer of seeds is sprinkled to circulate to the upper part of the sand pool. The top layer is a sand layer and the sand layer is covered with thatch. The thickness of the layer is 5 cm, the thickness of the seed layer is 2 cm, the temperature of the fine sand during storage is 20 degrees Celsius to 25 degrees Celsius, the humidity is 60% to 65%, and the time is one year;

Abstract

The invention discloses a method for growing seedlings of taxus chinensis, and belongs to the technical field of tree planting. The method includes processing seeds, to be more specific, soaking the harvested seeds in water, rubbing the seeds to remove seed coats of the seeds, and cleaning and drying the seeds; storing the seeds in fine sand for at least one year; selecting lands for seedling nurseries; preparing the lands, to be more specific, applying base fertilizers to the lands for the seedling nurseries, dividing the lands to obtain beds, and ditching the beds to form a plurality of planting furrows; sowing the seeds, to be more specific, sterilizing the seeds when the average air temperature in a current day is stabilized and is higher than 20 Celsius degrees, then uniformly sowing 25 kilograms of seeds in the planting furrows in each mu, and covering the seeds by soil; performing field management, to be more specific, performing daily irrigation, top application and disease and insect pest management on the tree seedlings, and constructing arch sheds; discharging the tree seedlings from the nurseries when the heights of the growing tree seedlings are 15 centimeters. The selected lands for the seedling nurseries are provided with water sources, and Ph (potential of hydrogen) values of the soil in the selected land range from 6 to 7. Sunshade nets cover the arch sheds. The method has the advantage that the problem that taxus chinensis is endangered due to low growth speeds and poor regeneration capacity of the taxus chinensis under natural conditions can be solved.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a method for raising yew seedlings. Background technique [0002] Taxus is a shallow-rooted plant. It is very precious because it contains paclitaxel, a special anti-cancer drug, and has high development and utilization value. However, under natural conditions, taxus grows slowly and has poor regeneration ability. Therefore, for a long time, it has been used worldwide No large-scale yew raw material forest base has been formed, so it is recognized as an endangered plant in the world. In 1994, yew was designated as a first-class rare and endangered plant by my country, and it was also recognized by 42 countries with yew in the world. Known as "National Treasure", the United Nations also explicitly prohibits logging. It is a veritable "Plant Giant Panda". Therefore, how to artificially cultivate yew and establish an artificial cultivation base is an urgent problem for us ...
