Description

Tianshima chestnut growth regulator and application thereof

Technical Field

The invention relates to a Tianshili (A.wilsonii Rehd.) growth regulator, application of the growth regulator and a method for improving the fruit yield of the Tianshili.

Background

The chestnut is a tree, the height of the tree is 15-20 m, and the chestnut is mainly distributed in forests with the elevation of 1500 m in China and south China. The Chinese chestnut seeds are one of the main sources of the medicinal material Chinese buckeye, the Chinese buckeye has the functions of soothing the liver, regulating qi, harmonizing stomach and relieving pain, is rich in triterpenoid saponin components, and is the most important medicinal material source for preparing the raw material medicament aescin. The inflorescence of the Ribes burejense is a cone-shaped inflorescence of a polyumbellate, the small inflorescence consists of 5-10 small flowers, and the flowers are of the same variety. Due to the serious flower and fruit dropping phenomenon of the adult Chinese chestnut trees, the fruit setting rate is very low (usually about 5-10%), the seed yield is low, and the development of the related Chinese buckeye medicinal material industry is severely restricted.

The plant growth regulator is a compound which is artificially synthesized or extracted and has similar action with natural plant hormone, can influence and regulate the growth and development of plants, comprises a series of plant life overall processes of cell growth, division, rooting, germination, flowering, fructification, maturation, shedding and the like, and is widely applied to various fields of economic crops, garden landscapes, medicinal plants and the like at present.

Studies have shown that each plant growth regulator has specific applications and that the application requirements are quite stringent, and that a specific efficacy can only be achieved for a specific target plant under specific application conditions, including external factors. Often, varying concentrations will produce opposite results, for example, promoting at low concentrations and inhibiting at high concentrations. Plant growth regulators have many uses, which vary depending on the species and target plant. For example: controlling germination and dormancy; promoting rooting; promoting cell elongation and division; controlling lateral buds or tillering; controlling the plant type (short, strong and lodging-resistant); controlling the sex of flowering or male and female, and inducing seedless fruits; thinning flowers and fruits and controlling fruit dropping; controlling the fruit formation or maturation stage; enhancing stress resistance (disease resistance, drought resistance, salinity resistance and freezing resistance); enhancing the fertilizer absorption capacity; increasing sugar or altering acidity; the flavor and color are improved; promoting latex or resin secretion; defoliation or catalytic estimation; preservation, and the like.

The applicant conducts a large number of tests and screens aiming at the aesculus chinensis to finally obtain a formula of the growth regulator capable of improving the fruit setting rate and the yield of buckeye, and in addition, the formula is unexpectedly found in practical application to improve the aescin content in the buckeye, so that the medicinal value of the buckeye medicinal material is favorably improved.

(2) the invention increases the aescine content in buckeye medicinal materials and improves the medicinal value of buckeye medicinal materials.

Detailed Description

The present invention will be described in detail below with reference to specific examples, but the present invention is not limited thereto.

30 Tianshima chestnuts with the same tree age (13-17 years) are selected from the same land of a Chinese buckeye medicinal material planting base in Shen-agriculture and forestry region in Hubei in 2017 and are randomly divided into three groups, 10 Chinese chestnut plants are arranged in each group, the tree ages of the three groups are not obviously different (P is more than 0.05), the plant spacing and the row spacing of all Tianshima chestnuts are more than 5m, and mutual interference is avoided.

A group of Tianshima chestnuts are planted conventionally: fertilizing for 2 times every year, applying 1.5-3Kg of organic fertilizer to each plant in spring and autumn, and spraying leaf fertilizer containing 0.3% of borax and 0.3% of monopotassium phosphate to branch groups in full-bloom stage and initial fruit stage of fruit trees until fruits are formed. Conventionally performing field management such as irrigation, drainage, weeding, disease control, pest control and the like, and harvesting semen aesculi in late ten days in 9 months.

Two groups of chestnut applied growth regulators: spraying a growth regulator on the branch groups at the full-bloom stage and the initial fruit stage of the fruit trees, wherein the spraying amount is 2 Kg/plant every week until the fruits are formed. The rest are planted and managed in the same group. The growth regulator formulation is as follows:

three groups of chestnuts were dosed in stages with growth regulators:

(1) and spraying a growth regulator containing GGR double Jier No. 8 onto the branch groups in the full-bloom stage, wherein the spraying amount is 3 Kg/plant every time every week until the full-bloom stage is finished. The formula of the regulator is as follows:

(2) spraying a growth regulator containing diethyl aminoethyl hexanoate and naphthylacetic acid to the branch groups at the initial fruit stage, wherein the spraying amount is 3 Kg/plant every time, and the fruit is formed. The formula of the regulator is as follows:

the rest are planted and managed in the same group.

And observing the inflorescence fruit setting rate during the test period, carrying out statistics, weighing and calculating the yield after the first fruit harvesting is finished in 10 months, then drying and crushing Chinese buckeye picked by the same fruit tree, detecting the aescin content in the Chinese buckeye, and carrying out continuous test for 3 years.
