Embodiment 1

[0021] The 1-year-old Taxus Mandia growing in the greenhouse was transplanted in the field without shading, and the pH of the soil was tested to be 6.5. Keep some of the above-mentioned 1-year-old Taxus Mandia in the greenhouse, the soil pH is 7.3, follow the normal fertilization, watering, management, and pruning, and test the paclitaxel content of the pruned branches and leaves.

[0022] The 1-year Mandia yew transplanted in the field, except that it is not pruned, is the same as some of the 1-year Mandia yews mentioned above that are kept growing in the greenhouse, and the same fertilization, watering, and management are carried out. . After a light rain in early May of that year, 20g of urea, 10g of superphosphate, and 10g of potassium sulfate were applied to each plant. After fertilization, irrigation was carried out. After a thunderstorm in early August, fertilize again, 20g of urea, 15g of superphosphate and 15g of potassium sulfate per plant. In the first ten days of...

Embodiment 2

[0024] The 2-year-old Taxus Mandia was kept in the greenhouse, and the soil pH value was 7.2. According to the normal fertilization, watering, management, and pruning, the paclitaxel content of the pruned branches and leaves was tested.

[0025] 3 acres of 2-year-old Taxus Mandia were transplanted in the field at an altitude of 600 meters. Before transplanting, 3000 kg of farmyard manure was applied, and the pH value of the soil was tested to be 6.3. Except for no pruning, the same fertilization, watering, and management are carried out as some of the above-mentioned 2-year-old Mandia yews that are kept growing in the greenhouse. After irrigation in the first ten days of May of that year, apply 30g of urea, 15g of superphosphate and 15g of potassium sulfate to each plant; after fertilization, irrigate. After a thunderstorm in early August, fertilization was applied again, 30g of urea, 20g of superphosphate, and 20g of potassium sulfate were applied to each plant. In early Nov...

Embodiment 3

[0026] Embodiment 3 and embodiment 4, the transplanting area is respectively 10 mus and 6 mus, and plot is located in Shanxi Jinzhong city loess hilly area, and altitude is respectively 850 and 900 meters, and annual average temperature is about 9 ℃, and January average temperature is -8 ℃, the extreme low temperature is about -18 ℃, the average temperature in July is about 23 ℃, the highest temperature is 38.5 ℃, the high temperature weather above 35 ℃ does not exceed one week, and the soil pH values ​​are 6.0 and 6.5 respectively. Before transplanting, apply 3500-4000 kg of base fertilizer, and then apply 1500-2000 kg of farmyard manure from the seedling ditch every spring, and add 100 kg of commercially available biofertilizer containing phosphorus and potassium-dissolving bacteria per mu before transplantation. The row spacing of transplanted plants was 80cm and 1200cm respectively. The content of available potassium and phosphorus in the soil can fully meet the needs of p...

Abstract

The invention relates to a cultivation and collection method for improving taxol content in taxus media branches and leaves, belonging to the technical field of medicinal plant cultivation. One-year-old or more than one-year-old taxus medias are cultivated in optimized soil with pH of 6.0 to 6.9 under sunny natural daylight; proper nitrogenous fertilizer, phosphate fertilizer and potash fertilizer are applied around summer begins and autumn begins each year, and newly growing branches and leaves in the current year are picked around winter begins, are dried in the shade or dried at the low temperature of 45 DEG C. According to the method provided by the invention, taxol content in taxus media branches and leaves can be improved by about 10 to 17%, and the quantity of branches of each taxus media is improved, thus effectively relieving shortage of medicine resource of taxus media, lowering the cost of medicine taxus media, and producing great economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant cultivation, in particular to a method for cultivating and harvesting Taxus Mandia, in particular to a method for cultivating and harvesting paclitaxel in branches and leaves of Taxus Mandia. Background technique [0002] Paclitaxel is used to treat metastatic ovarian cancer, breast cancer, lung cancer, and esophageal cancer. It is one of the hottest new anti-cancer drugs after Adriamycin. Resources, supply is limited, and the paclitaxel content in the leaves is very low, resulting in the shortage of raw materials for extracting paclitaxel. Yew, also known as yew and yew, belongs to the genus Taxus in the taxonomy of the gymnosperm phylum Taxaceae. It is an evergreen tree or shrub. It is a national first-class protected plant and is known as the "golden plant". Because the content of paclitaxel in Taxus chinensis is very low, even the short-leaf Taxus with the highest content currently re...
