Description

A method for chemical regulation of milk thistle

Technical field:

The invention belongs to the technical field of crop chemical regulation, and in particular relates to a chemical regulation method of milk thistle.

Background technique:

Milk thistle is an annual or biennial herb of the genus Milk thistle in the family Asteraceae. It is an excellent liver-protecting plant. The whole plant is used for carbuncle and erysipelas. Lower blood fat, protect heart muscle, protect brain, anti-X-ray function, have good curative effect on acute and chronic hepatitis, liver cirrhosis, fatty liver, liver injury caused by metabolic toxicity, cholelithiasis, cholangitis and perihepatic cholangitis and other hepatobiliary diseases . Milk thistle likes a cool and dry climate, has strong adaptability, and does not have strict requirements on water and fertilizer conditions. It is planted in a large area in the northeast, north, and northwest regions of China. The northeast region is the main production area of milk thistle in my country, and its output accounts for More than 70% of the country.

Milk thistle grows vigorously and is easy to grow leggy. In the current large-scale planting practice, the main inflorescences of milk thistle plants tend to grow very tall, much higher than the branch inflorescences, and the main inflorescences mature earlier, and the fruits are easily blown off by the wind before harvesting. Thereby causing great fly seed loss. Due to the large difference in height between the main inflorescence and the branch inflorescence, mechanical harvesting is difficult on the one hand; on the other hand, the mechanical harvesting loss of fruit is relatively large. Especially when the fertilizer and water conditions are better, the above problems are more serious.

In the current planting practice of milk thistle, when the fertilizer and water conditions are good, because milk thistle is easy to grow excessively, a large amount of nutrients are allocated to vegetative organs such as roots, stems and leaves, and less are allocated to reproductive organs such as inflorescences and fruits. The main inflorescence is too high, the number of inflorescences in the whole plant is small, and the number of effective inflorescences is small. Its due potential for increasing production cannot be fully realized.

In the current planting practice of milk thistle, the aqueous solution of chemical regulators such as chlormequat, paclobutrazol, and trinexapac-ethyl is used alone or in combination, and it is not possible to achieve the goal of growing milk thistle at various growth stages (from sowing to maturity). The purpose of effectively controlling the height of the main inflorescence of milk thistle, increasing the number of total inflorescences and effective inflorescences of the whole plant, and increasing fruit yield.

Invention content:

It is necessary to solve the current problems that the main inflorescence of milk thistle is too high, the maturity period of each branch inflorescence is different, and the field loss after fruit ripening is not conducive to large-scale mechanized harvesting; the vegetative growth of milk thistle is too vigorous, and the production potential cannot be exerted. To solve the problem of yield improvement, the technical method of the present invention is specially provided.

The regulating agent formula for the chemical regulation and regulation of milk thistle provided by the present invention is: 2-chloroethyl phosphoric acid (purity quantity): 6-benzyl adenine (purity quantity): pesticide adjuvant YZ901=75: 1: 24 .

The application period of the milk thistle chemical regulator of the present invention is: the period of time when the main stem height of the milk thistle reaches 40-80 cm after budding.

The aqueous solution of the milk thistle chemical regulating agent of the present invention is composed of: the ratio of the mixture of the chemical regulating agent to water is 1:200-1:400

Beneficial effects: when the present invention is applied to milk thistle, it can effectively reduce the height of its main inflorescence, increase the rate of main flowers and the regularity of each branch inflorescence, increase the number of effective inflorescences, and at the same time not reduce the thousand-grain weight of milk thistle fruit, It shows that the technical method can effectively regulate the distribution of nutrients between the vegetative organs and the reproductive organs of the milk thistle, thereby effectively improving the fruit yield of the milk thistle. At the same time, it can effectively reduce the field loss of milk thistle fruit during mechanical harvesting.

detailed description:

The technical scheme of the present invention is now described in detail in conjunction with specific implementation examples:

Embodiment 1: A method for chemical regulation of milk thistle. The specific method is as follows:

1. When the plant of milk thistle in the field is up to 80 cm after budding, the whole plant of milk thistle is sprayed with 2-chloroethyl phosphate (ethephon), 6-benzyl adenine (6-BA) , Chemical control agent aqueous solution mixed with pesticide adjuvant YZ901.

2. The composition of the chemical control agent composed of 2-chloroethyl phosphate (ethephon), 6-benzyl adenine (6-BA), and leaf spreader YZ901 is: 2-chloroethyl Phosphoric acid (pure amount): 6-benzyladenine (pure amount): pesticide adjuvant YZ901=75:1:24.
