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

[0032] The method that present embodiment utilizes exogenous substance to improve Sapindus fruit sequence comprises the following steps:

[0033] (1) Carry out the spraying of inflorescence exogenous substance at the initial flowering stage;

[0034] (2) Carry out the spraying of inflorescence exogenous substance in the blooming stage;

[0035] (3) Spray exogenous substances in inflorescences at the end of flowering stage.

[0036] 1. Materials and methods

[0037] 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.

[0038] Select 40 well-growing individual plants in the flower bud stage, and select 12 flower branches to hang tags on each individual plant. A total of 7 exogenous substances were selected, and 3 concentration gradients were designed for each; 3 ...

Embodiment 2

[0094] The method that present embodiment utilizes exogenous substance to improve Sapindus fruit sequence comprises the following steps:

[0095] (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;

[0096] (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;

[0097] (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 the concentrati...

Abstract

The invention discloses a method for improving soapberry infructescence fruit setting by utilizing exogenous substances. The method comprises the steps: spraying a spermine-containing solution, a spermidine-containing solution or a mixed solution of spermine and spermidine in a flowering phase of the soapberry. By spraying the spermidine and spermine of different concentrations in the flowering phase, the soapberry infructescence fruit setting can be obviously improved, internal content is possibly increased due to spraying and absorption of the spermidine and spermine, and losses caused by anobvious decrease of polyamine content in fruit development after the flowering phase are effectively supplemented. Therefore, the infructescence fruit setting number is improved to a certain degree.

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 sativa by using exogenous substances. 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 for the healthy dev...
