Problems solved by technology

In the prior art, Sapindus has a large amount of flowers, but the fruit setting rate is low, and the phenomenon of fruit drop is serious. There have been reports on the flowering dynamics, fruit development and fruit shedding of Sapindus, but there are few reports on the fruiting rate of Sapindus. Research

Embodiment 1

[0033] The present embodiment utilizes abscisic acid thinning flower to improve the method for Sapindus infructuration to comprise the following steps:

[0034] (1) Carry out the spraying of inflorescence exogenous substance at the initial flowering stage;

[0035] (2) Carry out the spraying of inflorescence exogenous substance in the blooming stage;

[0036] (3) Spray exogenous substances in inflorescences at the end of flowering stage.

[0037] 1. Materials and methods

[0038] The test site is located in Sapindus base of Manyuanchun Agriculture and Forestry Development Co., Ltd., Tiantai County, Zhejiang Province. Select a healthy single plant of Sapindus 7-year-old, which requires basically the same growth conditions and similar habitats.

[0039] Select 35 well-growing individual plants in the flower bud stage, and select 12 flower branches to hang tags on each individual plant. A total of 6 exogenous substances were selected, and 3 concentration gradients were design...

Embodiment 2

[0089] The present embodiment utilizes abscisic acid thinning flower to improve the method for Sapindus infructuration to comprise the following steps:

[0090] (1) Carry out the spraying of exogenous substance of flower bud in early bud stage, the exogenous substance of spraying is the mixed solution of gibberellin, abscisic acid and potassium dihydrogen phosphate, the concentration of gibberellin is: 50mg / kg, shedding The concentration of acid: 15mg / kg, the concentration of potassium dihydrogen phosphate: 8g / kg;

[0091] (2) Carry out the spraying of flower bud exogenous substance in bud expansion stage, the exogenous substance of spraying is the mixed solution of spermine and cytokinin, and the concentration of spermine is: 10mL / L, and the concentration of cytokinin is: 50mg / kg;

[0092] (3) Carry out the spraying of flower bud exogenous substance in bud dew white stage, the exogenous substance of spraying is the mixed solution of 4-chlorophenoxyacetic acid and borax, and ...

Abstract

The invention discloses a method for improving soapberry infructescence fruit setting by means of abscisic acid flower thinning. An allogenic material is sprayed in a soapberry flowering stage, and the allogenic material is a solution containing abscisic acid. The flower thinning effect can be achieved by spraying solutions containing abscisic acid of different concentrations, and soapberry infructescence fruit setting can be improved.

Description

technical field [0001] The invention relates to the technical field of high-yield cultivation of economic forests. More specifically, it relates to a method for improving fruiting of Sapindus infructescence by using abscisic acid to thin flowers. Background technique [0002] Sapindus mukorossi Gaertn. is an important traditional green tree species in the south of the Yangtze River in my country. Its peel is rich in saponin and its kernel is rich in oil. It is an important chemical raw material and biomass energy tree species. In the prior art, Sapindus has a large amount of flowers, but the fruit setting rate is low, and the fruit drop phenomenon is serious. There have been reports on the flowering dynamics, fruit development and fruit shedding of Sapindus, but there are few reports on the fruiting rate of Sapindus. Research. Improving the fruit-setting rate of Sapindus chinensis can effectively increase the yield of Sapindus sativa fruit, and lay a material foundation fo...
