Propagation method of Taxus chinensis
First, a few years before sexual reproduction, the emergence rate of wild yew seeds sown was less than 10%. Scientific research has found that the dormancy period of its seeds is as long as several years. After outdoor variable temperature storage and the use of drugs to break seed dormancy, the emergence rate can be increased to more than 70% and 80%, making it possible for the sexual reproduction of Taxus mairei to break through difficulties and to plant seedlings in large quantities. 1. Collect the mature fruit from September to October, put it in the basin, add the right amount of coarse sand and water, and put it on the plank.

How does the seed of yew reproduce to break seed coat?
The method of seed reproduction and seed coat damage of Taxus chinensis is as follows: the seed has a long post-maturity period and dormancy characteristics, and can germinate only after two winters and one summer under natural conditions, that is, it can be frozen outdoors in winter, exposed to high temperature and rain in summer, sown in autumn of the following year, if sown in spring, it can still be frozen outdoors after winter, and sown in a greenhouse after germination from late March to early April. It can germinate more than 20 days after sowing. If the seeds can be repeatedly rubbed with coarse sand and soles on rough cement ground, the inconspicuous tough seed coat will be worn out and the hard seed shell will be thinned (

How to change temperature for seed propagation of Taxus mairei?
The method of seed propagation and variable temperature treatment of Taxus mairei is as follows: Taxus seeds have the habit of double dormancy of radicle and Hypocotyl, and the radicle needs to go through the stage of high temperature above 25 degrees Celsius for one month to break dormancy. Hypocotyl needs to be at minus 3 degrees Celsius to minus 20 degrees Celsius for about one month. In order to accelerate seed germination early, as long as the seeds with damaged seed coat are mixed with wet sand and frozen in an environment below minus 3 degrees Celsius for 25 to 40 days, the Hypocotyl dormancy can be released after sowing in late winter or early spring.

Cultivation techniques of Taxus mairei
Taxus, also known as yew and red cypress pine, is an ancient tree species relic in the Quaternary ice age. There are 11 species of yew in the world, and there are 5 species in China, namely, Taxus mairei, Taxus yunnanensis and Taxus mairei Xizang. The biological characteristics of Taxus have high requirements on the ecological environment. Generally, adult trees need to grow for 100 ∽ for 250 years. Taxus is a precious plant on the verge of extinction. China has listed it as a first-class rare and endangered plant, and logging is also prohibited by the United Nations. Statistics in 1996 showed that wild yew in Yunnan accounted for 55% of the country's total.

Market prospects and cultivation techniques of Taxus chinensis?
Yew, also known as yew, also known as red cypress pine. Belongs to the shallow root plant, its main root is not obvious, the lateral root is developed. It is recognized as an endangered natural rare anticancer plant in the world. There are 11 varieties of yew in the world. We are suitable for planting Chinese yew. It is a high-priced plant with medicinal and ornamental functions. Now it is successful to raise seedlings by cloning technology, but the cultivation techniques are rarely reported, so we should focus on the control of underground pests and the prevention of root rot on the basis of conventional cultivation.

Cultivation and Management of Taxus mairei
Taxus is an evergreen tree with reddish-brown bark, shallowly longitudinally lobed, slightly curved and sickle-shaped leaves, dark green leaves and two gray-green stomatal bands. Dioecious, seeds oblate-ovoid, globose solitary, flowering from March to April, seeds mature in November. Taxus mairei is mostly propagated by seeds. After the seeds are ripe in November, the fleshy seed coat is washed and dried, then buried in a shady dry place with wet sand, covered with plastic film and grass curtains. The seeds should be turned twice a month in summer and autumn, and the seeds can be sowed and raised at the beginning of March of the following year. Seedling bed

Codonopsis downy mildew
There are irregular brown disease spots on the leaf surface and gray mildew on the back of the leaves (conidiophores and conidia), which can cause plant death. The prevention and cure method removes the residual leaves of diseased plants and is centrally burned; during the onset of the disease, 40% Frozen 300 times or 70% chlorothalonil 1000 times are sprayed once every 7 to 10 days for 2 to 3 times in a row.

New strain of Codonopsis pilosula 92-02
1. Variety introduction: Codonopsis pilosula is one of the main Chinese herbal medicines in Dingxi City, Gansu Province, with a planting area of about 18700 hm2 over the years, with a total output of more than 30, 000 tons, accounting for 40% of the national share. In 2001, Weiyuan County of Dingxi City was named "the hometown of Chinese Codonopsis pilosula" by the Township Organizing Committee of Chinese Agricultural Association. Party participation has become one of the important pillar industries in Dingxi City. However, at present, Codonopsis pilosula planted in the field is basically a mixture of many types, which has a negative impact on the yield and quality, and seriously restricts the sustainable development of Codonopsis pilosula industry. For this reason, breeding

Codonopsis rust
To harm the leaves. The leaf back of the diseased part is slightly raised, that is, the heap of summer spores, which breaks and spreads orange summer spores in the later stage. The disease was the most serious from June to July. Control method: ① removes litter in winter. During the onset of ②, 50% dinitrate powder was sprayed with 200x solution or 97% dichlorodium sodium 400x solution, once every 7 days, for 2 times in a row.
