How do you plant it?

How much is the yew seed per jin?

The price of yew seeds varies greatly due to different seed varieties, quality and market, but in general, the price of yew seeds is about 200-300 yuan per jin. Taxus is recognized as a natural rare anticancer plant on the verge of extinction in the world. Taxus is generally sold on the market because of its slow growth rate and poor regeneration ability under natural conditions. Taxus generally uses seed propagation and cuttage propagation to raise seedlings and transplant. The plant height and stem diameter of Taxus chinensis seedlings grow slowly in the two years before emergence, and the plant height generally grows about 10 cm a year. The growth is accelerated one year after transplanting, and the increase can reach 20-30 cm in 3-5 years.

Second, how to plant yew seeds?

1. Selection of species and sites

The seeds of Taxus mairei mature from September to October, and can be collected when the seeds are crimson. After the seeds are collected, the flesh is mashed in water for 3-5 days, washed and dried, and stored in a cool and dry place indoors. The forest soil with deep soil layer, loose structure, high humus content and good drainage should be selected for raising seedlings. Taxus chinensis has the characteristics of shade, drought and cold resistance. The pH value of the soil is between 5.57.0. in addition, Taxus chinensis likes cool and humid climate, can withstand low temperature below minus 30 ℃, and the optimum temperature is 20-25 ℃. It likes moisture but is afraid of waterlogging, so it is suitable for planting on sandy loam with loose, wet and good drainage.

2. Soil preparation and fertilization

After the seedling land is selected, the soil of the new seedling land is fertile but not fertilized, and the old seedling land must be fully fertilized, turn 20-25 cm in autumn and then shallow and fine Harrow in spring, and apply rotten fine manure while ploughing, to make a seedbed with a height of 15 cm, a width of 1.2 m and a length of 10-20 m.

3. Seed germination

The seeds must be treated with accelerating germination before sowing. Generally, there are two methods of accelerating germination: burying every other year and overwintering. Among them, the seeds of Taxus mairei can be soaked in 45 ℃ warm water for 3-4 days, and then disinfected with 1-2% copper sulfate solution when the seeds become milky. Then mix the wet sand with 60% relative humidity equivalent to 3 times the seed volume into a grass bag or wooden box and put it into the underground cellar. In addition, the pit temperature in summer should not exceed 18-20 ℃. When the cellar temperature is high, you can set up a shade shed above or open the pit door at night. Using this method, the seeds are buried in the second year of the autumn cellar for 24 days in the third year, and the seeds can be sown when 20-30% of the radicles germinate. The overwintering burying method is suitable for sowing seeds with picking, that is, the fresh seeds are removed from the seed coat in the autumn and then soaked and disinfected, and then buried with the same wet sand burying method as the other year. 20-30 days before sowing in the next spring, the seeds were exposed to the leeward to the shady slope, covered with plastic film and watered to keep moist, and can be used for sowing when part of the seed shell was cracked.

4. Seed sowing and field management

The sowing time is from April to May every year, and the sowing amount is 0.045 kg-0.05kg per square meter of seedling bed. When sowing, attention should be paid to filling the bed with water on the flat bed surface, and the seeds should be pressed into contact with the soil with wood rolling on the bed surface and then covered with river sand. The thickness of the seeds is 2-3 times that of the seeds, and it should be suppressed again after covering the river sand. During the seed germination period, birds should be watered according to the principle of less frequent watering. Spray Bordeaux solution with a concentration of 1% every 7-10 days to prevent sudden disease of the seedlings. The two-year-old seedling bed can apply rotten rare human fecal urine 3-5 times, ammonium sulfate 1-2 times, and ammonium sulfate 0.1 kg / 10 m each time. Wash the seedlings with clean water in time after spraying to prevent drug damage, and apply potassium fertilizer again in June and July to improve the quality of the seedlings.

5. Overwintering protection

Taxus seedlings need to take overwintering protection measures, 1-4-year-old seedlings are covered with soil or grass to prevent drought, the time of soil mulching should not be too early so as not to make the seedlings rot, cover the seedlings with soil before Frosts Descent to the Beginning of Winter, the thickness of soil cover is slightly 4-6 cm over the seedlings, remove the cold-proof soil after the Qingming Festival in order to prevent the seedlings from physiological drying, it is necessary to withdraw 2-3 times, and the seedlings should be watered in time after removing the soil.

Summary: the above is about the introduction of yew seed prices and seed planting methods, we should pay attention to the above yew seed prices only as a reference, the specific price should be based on the actual price. Growers can refer to the above prices and plant according to the above methods, hoping to help friends in need!
