5. Expanding fruit, improving quality and increasing production

Gibberellin

The increase of growth hormone in the granulosa cells treated with gibberellin promotes the elongation and expansion of the cells, and at the same time mobilizes the transport and accumulation of organic nutrients to the fruit granules, rapidly increasing the contents of the flesh cells, thereby increasing the fruit granules. ~ 2 times, which significantly increased the value of the goods. Although gibberellin alone can increase the effect of fruit granules, it also has the negative effect of making the stalks brittle and easy to granulate. BA (6-ba) and streptomycin can be added to prevent the specific cooperation. The method varies depending on the variety and method of use. When gibberellin is used to increase fruit size, it must be combined with good agricultural techniques to achieve the desired effect.

Triacontanol

with 0.5mg / L triacontanol +150g potassium dihydrogen phosphate, sprayed grapes after the yield of 613kg per mu, an increase of 101%.

B9

15 to 30 days before harvesting, spraying from 1000mg/L to 2000mg/L leaves can increase fruit firmness. If the fruit is soaked in the 1000mg/L～2000mg/L liquid after harvest, the storage period can be prolonged.

Mepiquat chloride

It can increase the absorption of calcium ions, prevent the browning disease of the fruit shrinkage disease, and reduce and reduce the core, increase the amount of pulp and improve the fruit quality.

Cytokinin + gibberellin

After the flowering of the Kyoho grape, the seeds were sprayed with cytokinin and gibberellin for 1 time, which can make the seedless fruit grow into the same size as the stone fruit, and the fruit can be increased by 50%. Help

Spraying with 500-800mg/L liquid in grape flowering stage or young fruit expansion period can promote the formation and differentiation of flower buds, increase fruit setting rate, increase sugar content and vitamin C content, fruit size is large and tidy, mature early 3 to 4d, increase production and improve quality.

Abscisic acid (ABA)

When the fruit begins to mature, spraying with 100-200 mg/L of abscisic acid can promote the coloring and ripening of red honey, pioneer and Ishikawa red varieties, and also improve the sweetness of the fruit. KT-30 nucleated cr: 10 to 10 days after flowering, soaking the ear with 20 milligrams/kg of Pythium medicinal solution for 5 to 10 seconds, can promote cell division, prevent falling flowers and fruit, and effectively promote grape fruit. Increase. Non-nuclear varieties: can be mixed with gibberellin better, that is, 15 milligrams / kg KT-30 and 100 milligrams / kg of gibberellin mixed evenly after the end of the falling flower and 15d after the dipping of grape spikes. It can promote cell division, prevent falling flowers and fruit, and can effectively promote the growth of grapes. It should be noted that the concentration of KT-30 should not exceed 20 milligrams/kg, and the fruit treatment time should not be too early, otherwise it will easily form large and small particles.

Note: KT-30 should be used with the device, the effect will be significantly reduced after 1d. KT-30 is very effective in promoting fruit development and increasing fruit. It has certain practical value and can be used as a fruit development promoter. Only when the tree is strong and the water is sufficient, the best results can be obtained. The application concentration and period have a certain range, and it is best to use low concentration and late period. It must be even and thoughtful when immersing fruit, smearing and spraying, otherwise it will easily produce deformed fruit and reduce the value of the commodity. When promoting fruit enlargement, the expansion rate should be controlled at about 20%, combined with appropriate fruit thinning.
