Cultivation Technique of Taxus cuspidata

1. Before transplanting, transplanting seedlings for soil preparation and seedlings shall be selected first: selecting water nutrient with good water retention performance, looseness and permeability, without grass seed and pests. For example, humus and perlite are mixed and prepared, and the specific ratio is generally 1:2 between perlite and humus. Other materials (such as crushed bean stalks and peanut hulls) can be added in an appropriate amount. The characteristics of compaction facilitate seedling growth.
2. The method of transplanting and transplanting yew seedlings can be done by using the hole planting method. First, scoop the bottom of the hole with a spatula to form a conical shape. The tip of the cone is about 5 cm away from the bed, and the root of the seedling is evenly stretched. At the bottom of the hole on the bottom of the hole, pay attention to the extension of the root, and then gently press the floating soil around the neck and the root of the seedling to the level of the root and neck of the seedling. The water should be irrigated in time to make the soil and the root of the seedling closely connected, and the purpose of cultivation is mostly. It is harvested from branches and leaves, so it can be densely planted.
3. The initial management after transplanting requires shading conditions after transplanting. Shady nets can be used. Reed foils, straw curtains, etc. can also be used. In particular, exposure at noon should be avoided. The initial management after transplanting is mainly water management. , It is best to spray irrigation, atomization effect is better, leaf spray is an effective method to maintain the balance of water in transplanted seedlings.
4. Protection and Management of Transplanting Seedlings
1) Protecting the seedlings with small arches: Adjusting the temperature and humidity with a small plastic shed, opening the shed's two agricultural films on a sunny day to cool down, change the air, cover at night, spray the seedlings once in 3-4 days, and keep the seedbeds 65%-70 % humidity and rodent protection. The first year after planting must be shaded with a shady net. In the second year, corn and other shady plants can be used for shading. There should be no shading after planting for three years.
2) weeding and top dressing: May to July, cultivating and weeding 2-3 times, combined with cultivating urea 5-10 kilograms, potassium chloride 3-5 kilograms per acre for cultivator, pour water or apply rain, or Can be sprayed with 0.25% urea and potassium dihydrogen phosphate.
3) Pest control: The yew has strong insect resistance, less pests and diseases, and occasionally spiders or aphids occur. It can be used to control pesticides such as dichlorvos and dimethoate.
Before yew seedlings are planted, the soil should be sterilized and sterilized with carbendazim 500-1000 times. In the rhizosphere, a small amount of 1000 times liquid “Wortuan” and other soil pesticide degradation agents are poured and then the rooting water is perfused. After 7 to 10 days of colonization, 97% of "Yashimeiling" was used to irrigate the rhizosphere of 3000 times liquid to eliminate soil-borne diseases and prevent root diseases such as standing and rooting. 7~10 days once, even two times.
Transplanting and Management Transplanting of Big Seedlings of Taxus cuspidata
1. Transplanting seedling age: Usually 2 years or 3 years or more.
2. Soil: Large seedlings are transplanted and choose the slopes or semi-shady slopes or the short valleys of the sun to choose the slightly acidic to neutral, loose, well-drained, water-free plots (soil, sandy loam, loam is preferred).
3. Transplanting season: Before transplanting in the spring before growing, transplanting should be carried out in the autumn before the new shoot is not stopped growing. Rainy weather should be selected for transplanting.
4. Planting density: The plant spacing of 60 cm 80 cm or 1 m 1 m is generally used.
5. Planting techniques: The planting process is: digging holes - filling soil - raising seedlings - practical - rooting soil - cultivating ridges - irrigating water.

Daejeon Management
1. Water: The field irrigation method is mainly sprinkler irrigation, sprinkler irrigation, irrigation control, soil is not compacted, irrigation is uniform, and the work efficiency is high; the forest cultivation uses the hole irrigation method. Seedlings require more water in the fast-growing period. Drought should be noticed during the seedling period. Continuous irrigation should be taken into account. Irrigation should be carried out immediately after the soil is topped. Irrigation time should be selected in the morning or in the evening. At this time, the amount of evaporation is small and the water temperature is different from the ground temperature. small. Jet irrigation can be used at high temperatures, which is conducive to cooling.
2. The cultivating and cultivating can prevent soil compaction, reduce water evaporation, increase the effective nutrient utilization rate in the soil, eliminate weeds, and promote the growth of seedlings. The cultivator is usually combined with weeding, but it must be done in a timely manner. It can be performed according to the soil moisture status after every irrigation or after the rainfall.
3, weeding
1) The weeds should be promptly cleared of weeds to prevent weeds from earning moisture, nutrients and light conditions, so that the seedlings grow robustly and the root system develops.
2) Taking into account the specificity of Taxus chinensis as a medicinal tree species, herbicides should be used with caution, mainly by manual weeding.
4. Fertilization of Northeast yew is mainly based on soil fertilization, and fertilization is appropriate depending on soil fertility before field planting. In order to promote the growth of shoots in spring, the main application of nitrogen fertilizer, application of urea 25 kg -35 kg / acre; autumn in order to promote the full lignification of new shoots and root growth, can be applied in early August phosphorus and potassium fertilizer 20-30 kg / acre .
5. Pest control The yew seedlings are sterilized with carbendazim solution before planting. After the seedlings are implanted in the pits, the roots are watered with a water-spooning 1000-times solution, such as Wotuan, to degrade the soil residue. Permeate the root water. After 7 to 10 days of colonization, 97% of "Yashimeiling" was used to irrigate the rhizosphere of 3000 times liquid to eliminate soil-borne diseases and prevent root diseases such as standing and rooting. 7~10 days once, even two times.
6, harvesting and processing generally grow more than 5 years, Northeast yew can receive some of the branches and leaves medicinal, more than 9 years can be a large number of harvesting medicinal purposes. After a few years, all the trunks can be cut down, and the sawing section can be dried and used as medicine. It can also be used as root medicine.

Laboratory destoner uses raw material and stones density difference to separate stones from seeds. It is used after seed cleaner & grader processing and Gravity Separator processing. It is normally used for vegetable seeds, grass seeds, flower seeds and other small seeds cleaning. Lab destoner is for fining cleaning to remove the stones, lumps.

Working principle

The destoner worktable is a rectangular structure. The top of lab destoner table is mesh grid, the middle is a perforated aluminum plate, and the bottom is wooden air guiding structure. The hopper is located in middle of this worktable; by adjusting the vibration frequency of the worktable and the bottom blowing air volume to achieve the separation of seeds and heavier impurities. The raw material is rapidly delaminated at the seed feeding location; heavier impurity move along the slanted sides of the rectangle to the upper end, and the lighter seed move to the lower end along the rhomboid. Table vertical length, table vibration frequency, the bottom fan air volume are adjustable to meet the small size seeds, different density seeds, sorting requirements. Lab de stoner brings further study basis data of the small seeds characteristics.
