Problems solved by technology

[0002] There are not many changes in the sex ratio of plant flowers in the prior art. For example, Chinese Patent Publication No. CN101292607A discloses "a method for regulating and controlling the sex ratio of Jatropha curcas flowers by chemical reagents", which is the effect of ethephon and gibberellin at the same time, but , it is not ideal to improve the ratio of male and female flowers of Jatropha curcas

Embodiment

[0020] The present invention uses Jatropha curcas at the Tung tree seed base in Luodian County, Guizhou Province as the test material. In this embodiment, the consumption of kinetin KT solution at 5 different concentrations is set, and distilled water spraying is used as a contrast.

[0021] Select kinetin KT solution, molecular formula C 10 h 9 ON 5

[0022] Preparation method: Weigh kinetin KT 1mg, 2mg, 3mg, 4mg, 5mg, and prepare 1mg / L, 2mg / L, 3mg / L, 4mg / L, 5mg / L kinetin KT solutions with distilled water. The above reagents are the original drugs from the factory and are used after kinetin KT is completely dissolved.

[0023] Determination of plants: plants with the ability to set fruit and more than 2 years old.

[0024] Spraying method: use the kinetin KT solution newly prepared by the above method, after the kinetin KT is completely dissolved, spray the Jatropha curcas in the flower bud stage of the first stubble, especially pay attention to the spraying of the flower...

Abstract

The invention discloses a new use of KT (Kinetin) in plant growth regulation. The KT is used for sex ratio regulation of barbadosnut floral organs to improve the ratio of female flowers to male flowers of the barbadosnut. Under a certain condition, the concentration of sprayed KT ranges from 1mg / L to 5mg / L, wherein the condition refers to barbadosnut age of more than two years; the whole branches of the barbadosnut in a first flower bud period is sprayed; sprayed droplets are fine and uniform; the limit of dosage requires that a sprayed part is wetted and fine droplets drop; the spraying time ranges from 14:30 to 16:30 in the afternoon in a sunny day; supplementary spraying is required if a rain day comes in 36 hours after spraying; and the optimal spraying concentration of the KT is 3mg / L. The invention solves the problem of low ratio of female flowers to male flowers of the barbadosnut and can improve the ratio of female flowers to male flowers of the barbadosnut by 14.80 percent to 36.18 percent, effectively improve the yield o single barbadosnut and achieve the purpose of yield increase.

Description

technical field [0001] The invention belongs to the application field of plant growth regulators, and in particular relates to a new application of kinetin KT in plant growth regulation. Background technique [0002] There are not many changes in the sex ratio of plant flowers in the prior art. For example, Chinese Patent Publication No. CN101292607A discloses "a method for regulating and controlling the sex ratio of flowers of Jatropha curcas by chemical reagents", which is the effect of ethephon and gibberellin at the same time, but , it is not ideal to improve the ratio of male and female flowers of Jatropha curcas. As one of the plants that can produce biodiesel, Jatropha curcas seeds are rich in oil, the oil has strong fluidity and good quality, and has high research value and economic value. While it is being more and more widely cultivated as an energy plant, Its potential medicinal value is constantly being researched and developed more deeply and systematically. J...
