Embodiment 1

[0013] Choose to measure the crown diameter of the plant in the spring leaf-expanding period of the maple ingot, and trim the top tip of the maple ingot that has grown for 5 years. After pruning, the plant height is 1.5 meters, and then dig a ring ditch (15 cm wide) , 15 cm deep), Uniconazole was applied at a dose of 0.1 g / m (crown diameter). Specifically, first dissolve the weighed pure product of uniconazole in an appropriate amount of methanol, then dissolve it in 10 liters of water, and pour it evenly in the ring ditch. For the number of inflorescences of flowering plants, 10 inflorescences were randomly marked for each plant for observation, and the number of flowering inflorescences, male flowers, and hermaphrodite flowers were recorded respectively.

Embodiment 2

[0015] Example 1 was repeated with the following difference: the dose of uniconazole used was 0.2 g / m.

Embodiment 3

[0017] Example 1 was repeated with the following difference: the dose of uniconazole used was 0.3 g / m.

Abstract

The invention discloses a method for promoting acer truncatum bisexual flower formation by utilizing uniconazole and relates to the field of plant growth regulation. During a spring leaf-expansion period of acer truncatum, uniconazole is applied to the root of acer truncatum, the chemical application dosage is adjusted to be 0.1-0.5 g/m according to the acer truncatum crown diameter. According to the method, a certain amount of acer truncatum is adopted mainly to promote reproduction growth of acer truncatum, flowering of the acer truncatum ahead of time is promoted, and the bisexual flower formation proportion is improved. Through the treatment by the method, the number of inflorescences during a flowering phase of acer truncatum is 1.90 times that of an untreated plant, the flowering number of each inflorescence and the treatment mode have no remarkable difference, the number of male flowers of each inflorescence has no remarkable difference, the bisexual flower number of each inflorescence is increased from 2.33 to 8.80, and the proportion of the male flowers to the bisexual flowers is reduced from 11.67:1 before the treatment to 2.95:1. The method is easy to operate and low in cost, an effect of promoting bisexual flower formation is remarkable, and the method has good application prospect and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of plant growth regulation, in particular to a method for promoting the formation of hermaphrodite flowers of the maple indica by using uniconazole. Background technique [0002] Yuan Baofeng ( Acer truncatum L.) Also known as North China Wujiao maple, Pingji maple, etc., it belongs to the genus Aceraceae. It is produced in the Yellow River Basin, Northeast my country, Inner Mongolia, Jiangsu, Anhui and other places in China. It is a kind of VA with strong adaptability and stress resistance. Mycorrhizal tree species are widely used in barren hill afforestation and garden landscape construction. The oil content of Yuanbao maple seed kernel is 46-48%, the protein content is 27.15%, and the vitamin E content is as high as 125.23mg / 100g; it is an excellent oil and edible resource. Yuanbao maple seed oil has been approved by the Ministry of Health of China in 2011 Approved as new resource food. [0003] Yuanbao Maple fl...
