Method for controlling infection in cutting propagation of Yunnan manyleaf Paris rhizome and improving planting benefit

Abstract

The invention discloses a method for controlling infection in cutting propagation of Yunnan manyleaf Paris rhizome and improving planting benefit. The method comprises the following steps of selecting a seedling, dividing a cut block, performing wound processing for preventing infection, performing concentrated seedling growing, transplanting to field, performing field management, performing intertillage and weed elimination, performing water content management, performing fertilizer adding and earthing-up, controlling insect diseases, sunning for drying, and performing secondary propagation according to a same method after cultivation and growth for 3-4 years. The method of the invention has functions of effectively controlling the infection rate in cutting propagation of the Yunnan manyleaf Paris rhizome, improving emergence rate and breeding speed, controlling the infection rate of harmful bacteria below 5%, realizing high emergence rate which is above 90%, realizing flowering and fruiting in the year in which transplanting is performed, greatly shortening a seedling growing period, reducing seedling growth cost, increasing growth benefit, shortening an investment period of the Yunnan manyleaf Paris rhizome from original 8-10 years to 4-5 years, increasing cash flow speed, and facilitating production at a next period.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for controlling infection of Prunus yunnanensis cut propagation and improving planting benefits. Background technique [0002] [Parispolyphyllavar.yunnanensis (Fr.) Hand.Mass.] is a perennial herb of the genus Paris in the family Trilliaceae. Yunnan Zhonglou has been recorded in the previous editions of "Chinese Pharmacopoeia", and its rhizomes are used as medicine. The rhizomes are rich in phytosterols, steroidal saponins, flavonoids and other medicinal ingredients, which have anti-cancer, hemostatic, anti-inflammatory, analgesic, cough and asthma and Immunomodulation and other activities are the main components of Yunnan Baiyao and Gongxuening. [0003] Yunnan Zhonglou is a kind of traditional Chinese medicinal material with wide application and good market prospect. The growth period of wild Zhonglou Yunnan is more than 10 years, and artificial cultivation also takes 8-10 yea...

Problems solved by technology

However, no matter whether it is propagated with terminal buds or without terminal buds, it is easy to cause infection on the cut surface, and the infection rate can usually reach more than 15%. Cutting propagation is the key to the emergence rate and success of reproduction, and it is an effective way to realize the sustainable utilization of resources

[0005] Chinese invention "A method for cutting and growing seedlings of Chonglou rhizomes", application number CN200710066296 discloses a method of using cytokinin to treat the tubers of Chonglou yunnanensis; Chinese invention "Method for raising seedlings by cutting and cutting the tubers of Chonglou yunnanensis", application number CN200810233590 Disclosed is a method for raising seedlings by high-fold cutting of Polyphylla polyphylla; however, the loss rate of cutting sections is serious, and seedlings are not uniform, which cannot solve the problem of infection of the cutting surface of the polyphylla cuttings, and it is difficult to popularize and apply
