Description

Pharmaceutical composition for preventing or treating xanthorrhiza of pepper tree

Technical Field

The invention belongs to the technical field of plant growth regulators, and particularly relates to a medicinal composition for preventing or treating xanthorrhiza of pepper tree.

Background

The pepper is Rutaceae, Zanthoxylum shrub, woody vine or small arbor, the peel is the raw material of essence and spice, the kernel can extract pepper oil, it is excellent woody oil, the tender bud has unique hemp fragrance and rich nutrition, it is regarded as precious woody bud vegetable by people, the leaf can extract essence, it can be used as seasoning, it is edible or made pepper tea, the flower bud can be used as high-grade dish by adopting honey, the root can be used as medicine. The zanthoxylum bungeanum is mainly distributed in Shaanxi, Sichuan, Gansu, Shandong, Yunnan, Guizhou, Shanxi, Hebei and Henan of China (the research status and development trend of the byproducts of zanthoxylum bungeanum at home and abroad, Xueting and the like, Chinese seasonings, 12 th period of volume 38 in 2013, page 106 in published day, 12 month 31 in 2013, general research outline of zanthoxylum bungeanum, sojourn and the like, Chinese seasonings, 10 th period of volume 41 in 2016, page 149 in page 2016 and 10 month 31 in 2016).

Chinese prickly ash planting area is large. At present, Sichuan province is a province with large planting area of Chinese prickly ash, and officially counted area of Chinese prickly ash is about 500 ten thousand mu (containing red pepper), wherein actual area of green prickly ash is about 300 ten thousand mu. The Chongqing city is also the main production area of green Chinese prickly ash, and the actual area is about 150 mu of a Chinese prickly ash; the planting area of the green pepper in Yunnan is about 120 ten thousand mu; the planting area of the green Chinese prickly ash in Guizhou is about 100 ten thousand mu; other provinces also have a small amount of green pepper planted, such as about 50 ten thousand mu in the areas of Guangxi, Guangdong, Hunan and the like. The planting area of the green Chinese prickly ash in China should reach 750 ten thousand mu. According to the current development trend, the area of the national green pepper is estimated to reach 1000 ten thousand mu in 2020.

By 2018, the planting area of the peppers in Jiangjin area in Chongqing reaches 3.47 ten thousand hectares, the production rate is 2.40 ten thousand hectares, the annual output of the fresh peppers is 27 ten thousand tons, and the output value is 32.7 hundred million yuan. The planting density of the pepper is about 100-. The green Chinese prickly ash has become a new economic growth point in low-altitude mountain areas. According to the knowledge, the people in south areas such as Chongqing have the habit of eating the Chinese prickly ash in the past, but the use amount of the Chinese prickly ash in the north areas of China far exceeds that in the south. According to the introduction of some purchasing companies in Jiangjin area, 80% of the dry peppers purchased by the suppliers are sent to northern areas such as Shandong, Shanxi and northeast provinces. In addition, the Chinese green prickly ash is exported to southeast Asia, America, Europe and other places in the world.

However, while the zanthoxylum industry gradually expands to enhance the work, some diseases affecting the zanthoxylum output cannot be effectively controlled, and the zanthoxylum yellow disease is more prominent in expression. The Zanthoxylum bungeanum Hemsl is a problem which is not effectively prevented and solved all the time in the growth process of the green zanthoxylum bungeanum, and is called as 'zanthoxylum bungeanum cancer'. At present, the area where the yellow flowers of the Chinese prickly ash occur is wide, the number of cases is large, and particularly the occurrence rate of large bases is increasing continuously. After the green pepper blooms yellow flowers, pistils degenerate, the fruit setting capability is low, the yield is obviously reduced, even the green pepper is harvested absolutely, and the economic benefit of farmers is seriously affected. The yellow tree is characterized in that: (1) the florets which have bloomed yellow flowers are much larger and longer than normal florets, and the development of the florets is obviously advanced. (2) The male flower pillar is obviously differentiated, and the female flower pillar is short and small, and is completely different from the normal flower in shape. (3) The new leaves of the yellow pepper tree are much smaller than those of the normal fresh leaves, and the old leaves of the yellow pepper tree are upward-rolled, so that the fresh leaves are obviously lack of nutrition. (4) Some trees have a part of branches with yellow flowers, and some branches have a part of yellow flowers, and the other branch has a part of yellow flowers which bloom normally.

At present, no exact optimal method capable of completely preventing the yellow flowers of the peppers exists, and at present, people mainly adopt the following methods for treatment: (1) cutting branches with yellow flowers to prevent the branches from expanding continuously; (2) removing roots of the whole tree, which are needed to be broiled by a plurality of branches, and disinfecting soil. After the tree is planed, the original tree nest is not required to carry seedlings, and the seedlings are replaced at the position for supplementing.

The method is the method which is most applied at present, but on one hand, the method is time-consuming and labor-consuming, and the time for re-cultivating a pepper tree to reach the full stage is required for several years, so that the yield of pepper is seriously influenced; on the other hand, even if branches with yellow flowers are cut off, other branches have the problem of yellow flowers opening, and the problem cannot be solved fundamentally.

For example, patent document with publication number CN108934722A discloses a method for preventing and treating yellow flower disease of pricklyash tree, which can solve the problem of fruit failure due to yellow flower blossom by improving soil and optimizing the control of pesticide, and can recover fruit and achieve a fruit yield of above 50%. However, the method solves the problem that the pepper has no fruit bearing after the blossom is opened by cultivating root systems, repairing tree bodies and regulating inflorescences, and has the following defects: (1) the used medicaments are many and need to be weighed and used separately; (2) the treatment times are many, and 4 times of treatment are needed before and after treatment, so that the time and the labor are consumed; (3) the time period from the first treatment to the last treatment is long, and about 50-60 days are required.
