Problems solved by technology

[0004] In order to protect this precious natural resource, promote the growth and rational utilization of resources, people have done a lot of work, and have vigorously introduced and bred yew resources to develop yew resources, but the cultivation of seedlings has always been the bottleneck of the development of yew
The original method has a low emergence rate and uneven seedlings, making it difficult to adapt to the needs of large-scale planting
Also have as disclosed seedling technology of Chinese patent 200310110132.1 and Chinese patent 03135544.7, all can not adapt to the seedling cultivation of yew

Embodiment 1

[0025] The yew seedling cultivation and planting technology of the present invention adopts the following steps:

[0026] 1. Seed collection and processing

[0027] After mid-October, the outer testa of the fruit of Taxus chinensis is collected when the outer testa is dark red. The harvested seeds are retting at room temperature for a week, the pulp skin is washed off, the seeds are sun-dried to remove the waxy layer, and the seeds are soaked in yellow mud water for 10 minutes for disinfection. , to dry the surface water;

[0028] 2. Seed storage

[0029] After the yew seeds are harvested, there is a one-year physiological maturity period and they are in a dormant state. Store the above-mentioned treated southern yew seeds in a large stone mortar with holes at the bottom with a volume ratio of pure river sand to seeds of 3:1 in a cool and ventilated place or in a cellar for 12 months, turning over every 1-2 months Once, and check pests and diseases, rodent prevention;

Embodiment 2

[0044] The yew seedling cultivation and planting technology of the present invention adopts the following steps:

[0045] 1. Seed collection and processing

[0046] Put the collected and mature yew seeds at room temperature for a week, wash off the pulp skin, sun-dry the seeds to remove the waxy layer, soak the seeds in yellow mud water for 10 minutes, and dry the surface water;

[0047] 2. Storage

[0048] After the yew seeds are harvested, the above-mentioned treated yew seeds are stored in natural wet sand stratification or in a 5°C cold storage for 12 months at a ratio of natural wet sand stratification to seed volume of 3:1, and every 1-2 Turn the pile once a month; check for pests and diseases, and prevent rodents;

[0049] 3. Land preparation

[0050] Choose shady land, convenient drainage and irrigation, and a thick and loose soil layer as a seedbed, and make the land into a nursery field with a net width of 0.9 meters, a walkway width of 0.4 meters, and a height of...

Abstract

The invention relates to a Chinese yew seedling cultivation technology which comprises the steps of: retting seeds, washing flesh and peeling off, removing wax coat; disinfecting; drying in the sun; storing in a big stone mortar with holes for 12 months; when the seeds crack and expose white parts, dipping the seeds in 0.05% potassium permanganate liquid for disinfecting; washing with clean water; drying in the air and then seeding after the beginning of winter and before the beginning of spring; after seedlings come out, applying 800 multiple thiophanate to stems, leaf backs and leaf surfaces of the seedlings; sun shading; outplanting when the seedlings are 20-30 cm in height, and have ground diameter of 0.3cm and 3-5 lateral branches. The Chinese yew seedling cultivation technology has the advantages of high seedling yield, strong seedling, fast growth and early fruiting; in addition, space among Chinese yew seedlings can be used to plant soybeans to increase grain income, moreover, roots of soybeans can increase biological nitrogen and improve soil for the rooting of Chinese yew, and the soybean seedlings can shade the Chinese yew seedlings for resisting high temperature, thereby improving the survival rate of the Chinese yew seedlings. The invention combines agriculture and forestry, develops ecological agriculture, and achieves both agriculture benefits and forestry benefits.

Description

technical field [0001] The invention relates to a seedling raising and planting technology, in particular to a yew seedling raising and planting technology. Background technique [0002] Yew, also known as yew and yew, is an ancient tree species left over from the Quaternary ice age, and is known as the "giant panda" in the plant world. It protects wild plants at the national level and has important economic value and scientific research value. Its extract - paclitaxel is more expensive than gold, and it is a valuable medicinal material for the treatment of advanced cancer. [0003] Yew also has diuretic swelling, treatment of kidney disease, diabetes, nephritis edema, dysuria, gonorrhea and other effects. [0004] In order to protect this precious natural resource and promote resource growth and rational utilization, people have done a lot of work and developed yew resources through vigorous introduction and breeding, but the cultivation of seedlings has always been the b...
