Embodiment 1

[0016] A method for promoting flowering and fruiting of southern yew female plants, comprising:

[0017] (1) Selection of test site:

[0018] The test was carried out in Sufeng Forest Farm, Hengpi Village, Jiaochang Township, Fenyi County, Xinyu City, Jiangxi Province. The area has a typical subtropical monsoon-type humid climate, with an average annual temperature of 18.5°C, an average annual rainfall of 1643.6mm, and a frost-free period of 310 days throughout the year. The soil in the test site is yellow-red soil, containing 78.67 mg·kg of hydrolyzed nitrogen -1 , available phosphorus 8.61mg·kg -1 , available potassium 63.55mg·kg -1 , organic matter 23.53g·kg -1 , pH value is 5.4.

[0019] (2) Southern yew material selection

[0020] The test material is a 13-year-old female Taxus chinensis plant that is managed consistently in the forest farm, grows well, and is free from diseases and insect pests. The plant height is about 3.5m and the ground diameter is about 9.3cm. ...

Abstract

The invention discloses a method for promoting flowering and fruiting of southern yew female plants. The method comprises: spraying 1500 mg·L on the leaves of southern yew female plants for several times ‑1 A mixture of paclobutrazol and 0.5% Tween‑20. The method of the present invention is by continuously spraying 1500mg·L to the southern yew female plant ‑1 The mixed solution of paclobutrazol and 0.5% Tween‑20 increased the proportion of flowering branches of reproductive shoots on the standard branches of Taxus chinensis by 18.00% compared with the control, and the number of megaspore bulbs on the annual new branches increased by 14.88% compared with the control. The proportion of fruiting branches and the total number of seeds increased by 1.64 times and 3.25 times respectively compared with the control, the number of seeds on the annual new branches increased by 1.76 times compared with the control, and the average value of the transverse diameter, longitudinal diameter and quality of the seeds increased by 32.17%, 30.19% and 1.88 times respectively compared with the control .

Description

technical field [0001] The invention relates to a method for promoting flowering and fruiting of plants, in particular to a method for promoting flowering and fruiting of southern yew female plants. Background technique [0002] Southern yew (Taxus chinensis var.mairei), belonging to Taxus genus Taxus, is a first-class protected gymnosperm plant in my country. It grows slowly in natural forests, but grows faster in artificial cultivation. It has important medicinal and ornamental Value, with good market and industrialization prospects. [0003] At present, the research on the southern yew timber forest mainly focuses on genetic improvement and optimized cultivation, while there are few studies based on the reproductive growth of southern yew flowers and fruits. Because the fruiting period of the southern yew is relatively late, it usually takes 7 to 8 years to enter the early stage of fruiting. Shortening the fruiting period and increasing the amount of seeds are not only th...
