CN103109688B - Method for delaying sprout tumbling at high temperature and raising yield and alkaloid content of pinellia ternate - Google Patents

Abstract

The invention discloses a method for effectively delaying sprout tumbling at high temperature and raising yield and alkaloid content of pinellia ternate. During the growing process of pinellia ternate, 0.03-0.3mmol/L jasmonic acid methyl ester aqueous solution is sprayed from an external source, so that the sprout tumbling of pinellia ternate can be delayed by at most 9 days, the yield of pinellia ternate can be raised by 2%-5%, and the alkaloid content of pinellia ternate can be raised by 6%-38%. The method is easy to implement, convenient to operate, easy for pesticide farmers to master, convenient to promote, low in investment and high in profit.

Description

A kind of method delaying the tuber of pinellia high temperature time of falling seedling raising tuber of pinellia output and tuber of pinellia alkaloid

Technical field

The invention belongs to traditional Chinese medicine planting technology field, be specifically related to the planting technology of the tuber of pinellia.

Background technology

The tuber of pinellia (Pinellia ternata Breit.) is Araeceae Pinellia Tenore herbaceos perennial, is one of famous traditional Chinese medicine of China, is used as medicine with stem tuber, has the effects such as eliminating dampness and eliminating phlegm, stopping nausea and vomiting by lowering the adverse flow of QI, clear ruffian dissipating bind.The tuber of pinellia avoids that drought is afraid of flood, resistance to the moon fears solarization, and between Grain in Ear midsummer, because high temperature and intense light irradiation make the respiration of the tuber of pinellia strengthen, the consumption of material exceedes photosynthetic accumulation, causes cellular plasm structural deterioration, and withering appears in part, is commonly called as down seedling.It is adapt to the one of unsuitable environmental condition that the tuber of pinellia falls seedling, is also a kind of effective asexual reproduction method.But with regard to the tuber of pinellia is produced, the seedling that falls shortens the vegetative period of the tuber of pinellia,

Had a strong impact on the output of the tuber of pinellia, thus anti-down seedling is a very important well stimulation.

Jasmonates compound is the plant endogenous growth substance that a class newly confirms, they are similar to abscisic acid (ABA) in some physiological functions.Methyl jasmonate (MeJA) is the one in Jasmonates compound, easy permeate through cell membranes, and is not easily ionized, therefore as a kind of multiple defense reaction of endogenous signal molecule involved in plant.Have now found that MeJA take part in the numerous Resistant reaction of plant as signaling molecule, there is important stress response and regulating and controlling effect, and research shows that methyl jasmonate uses in multiple Medicinal Plant Cell is cultivated, Be very effective.

Summary of the invention

The object of the present invention is to provide one in Su Banxia planting process, spray certain density methyl jasmonate by external source, delay the tuber of pinellia high temperature time of falling seedling, improve the method for total alkaloid content in tuber of pinellia Tuber yields and stem tuber.

The present invention is achieved through the following technical solutions:

(1) preparation of the aqueous solution is sprayed: get commercially available technical pure or chemical pure methyl jasmonate is mixed with 0.03 ~ 0.3mmol/L aqueous solution;

(2) spray the time: select the morning 10 time spray or afternoon 4 ~ 5 time spray;

(3) spray season and number of times: according to different areas, weather, May ~ June, have 3 blades to be expanded to completely till plant starts down seedling so that tuber of pinellia plant is long, use 5 ~ 6 times altogether, used once at interval of 10 days;

(4) spraying method: the methyl jasmonate aqueous solution above-mentioned (1) prepared loads in agroatomizer, the methyl jasmonate aqueous solution is sprayed on the blade of tuber of pinellia plant by sprayer, to make above the blade of tuber of pinellia plant all or major part is evenly covered with the methyl jasmonate aqueous solution and is advisable.

The described tuber of pinellia is Su Banxia, is the distinctive genuine traditional Chinese medicine in North Huaihe River Area of Anhui Province, famous special local product, and powder foot, look white.

As shown from the above technical solution, after the tuber of pinellia sprays certain density methyl jasmonate, the time dilation of falling seedling of tuber of pinellia plant 2 ~ 9 days, and its output adds 2% ~ 5%, the total alkaloid content of tuber of pinellia stem tuber too increases 6% ~ 38% simultaneously.The invention process is simple, and easy to operate, common medicinal herb grower can grasp, and be easy to be accepted by medicinal herb grower, easy to utilize, less input, and results are comparatively large, significantly can delay the tuber of pinellia time of falling seedling, improve the total alkaloid content of tuber of pinellia land for growing field crops output and tuber of pinellia stem tuber.
