Problems solved by technology

[0005] Based on the technical problems existing in the above-mentioned prior art, the present invention provides a new idea of ​​yew seed seedling raising technology, which further solves the problem of low seedling emergence rate and low survival rate of yew in large-scale artificial production in the prior art. low, large labor input, resulting in increased production costs, low profit technical problems, so that the medicinal, timber and ornamental value of yew can be fully utilized

Embodiment 1

[0020] Select a piece of fertile land as a seedling base, apply 100-150kg of farmyard manure per mu to the selected seedling base for deep plowing, and then pile up the seedling base so that the depth of the pile is 15-20cm, and the distance between the pile and the pile is 10-15cm , dig a pit from the top of the pile, the depth of the pit is 18-22cm, apply 0.5-0.8kg of urea, 0.1-0.3kg of ferrous sulfate and 0.6-0.9kg of superphosphate to it, and cover it with soil to make the pile Return to compost fermented fertilizer for use; in October-November, collect the red yew seeds, remove the peel layer and pulp layer, then wash the yew seeds with clean water and soak the yew seeds with potassium permanganate solution for 0.5- 1.2h, take it out and drain, and soak in warm water at 50°-55° for 1-1.5h, and finally take it out and dry it for storage; the yew seeds are pre-shucked one month before sowing, and firstly use 60 °-70° warm water and alcohol are mixed according to the mass ra...

Embodiment 2

[0022] Carry out planting yew according to the method for embodiment one, wherein farmyard manure is pig manure, cow dung, poultry manure one or more mix according to arbitrary proportion, and be soaked in the potassium permanganate solution of 0.1-0.25% with concentration For the yew seeds, cover the yew seeds with sand to 2-8cm after the seeds are planted into the mound, maintain the surface temperature at 20-30 degrees Celsius, and maintain the moisture at 65-70% for cultivation, so that the survival rate of the yew and The nursery rate is increased by 10-15% respectively, which further ensures that the cost rate of the yew seed cultivation process is reduced, improves the planting profits of the growers, and satisfies the conditions for large-scale production of yew and shortens the production time. The planting time of yew is shortened, and its medicinal, material and ornamental values ​​have been fully utilized.

Abstract

The invention relates to the technical field of agriculture, in particular to a method for breeding Chinese yew seeds. The method comprises the steps of selection of a seedling raising field, sorting of a seed bed, collection and treatment of seeds, pre-sowing treatment and sowing of seeds, field management and transplanting, young growth tending, planting and breeding. Due to the selection of the seeding raising field and sorting of the seed bed, the defect of severe field selection existing in the conventional Chinese yew seed planting method is overcome; through the collection and treatment processes of seeds, the dormant period of seeds is shortened, the pre-hull-breaking treatment difficulty before sowing is lowered, and the breeding period of the Chinese yew seeds is further shortened; and through treatment before sowing as well as field management and the young growth tending process after sowing, so that the survival rate and outplanting rate of Chinese yew are increased, basic conditions are provided for the production of large-scale production of Chinese yew, and the medicinal, material and ornamental values of Chinese yew are brought into full play.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to the field of yew seed cultivation technology. Background technique [0002] Taxus, commonly known as yew, belongs to shallow-rooted plants. It is recognized as a natural and precious plant on the verge of extinction in the world. It is a precious anti-cancer plant. Taxol extracted from roots, stems and leaves has good anti-cancer effects. The price is very expensive, and it is a precious and frequent plant with high development value that integrates medicinal, material, and ornamental uses. However, due to the slow growth rate of yew in the natural environment, poor regeneration ability, and low breeding survival rate, resulting in The difficulty of large-scale planting of yew has been great so far, and its medicinal, timber and ornamental value cannot be fully utilized. [0003] In view of this, many researchers have made contributions in this respect, such as the "Yew Br...
