Application of Regulators for Grape Flowering and Yield Enhancement
Brassinolide
It is sprayed once in each of grape bud stage, young fruit stage and fruit expansion stage. The dosage is 0.03~0.04 mg/L, which can stimulate the intrinsic potential of plants, improve seed vigor, promote root development, regulate the robust growth of plants, and improve fertilizer utilization. , to enhance crop stress resistance and improve seed setting rate.
Naphthalene acetic acid NAA
When the grapes are the size of pea grains, the fruit set rate can be improved by impregnating the ear with 300 mg/L liquid medicine.
Gibberellic acid
Using 4-6.7 mg/L gibberellic acid before flowering can lengthen the ear, and spraying the ear with 10-20 mg/L gibberellic acid about 7d after flowering until the ear is completely wet or soaked, can enlarge the fruit.
Note on use: When various grape varieties are used for different purposes, the period of use, concentration, and application site are also different, and the dosage of the drug varies greatly, especially for "Kyoho" and "Seekless White", please be sure to grasp the period of use, concentration and spraying parts, such as elongated flower spikes: it must be sprayed on the whole plant 10-14d before the first batch of flowers blooms, and the flower spike can be sprayed separately 10-14d before the second batch of flowers blooms. Use 4~5.35 mg/L at high temperature and 5.35~6.7 mg/L at low temperature.Or if the fruit size is increased: "Hongti", "Kyoho" and other seeded varieties are recommended to use 20 mg/L mixed safener on the fruit ear when the fruit is 10-12 mm and 14-15 mm, respectively, for a total of 2 times. .
Thidiazuron
In the flowering stage and fruit expansion stage of grapes, 4-6 mg/L thidiazuron is sprayed evenly once, focusing on the grape ears, which can improve the fruit set rate and promote fruit expansion.
Forchlorfenuron CPPU
Using 10-20 mg/L chlorpyrifos 10-15 days after flowering, soaking young ears for 30 s can adjust growth, prevent flowers and fruits from falling off, and promote fruit enlargement. Attention should be paid to the use, according to the specified period, concentration, dosage and method. Too high concentration can cause hollow and deformed fruit.
Triacontanol
Spraying 0.15-0.20 mg/L triacontanol in two times during the flowering stage and the expansion stage of young fruit can increase the "Baiyu" grape by 16.5%.
Gibberellic acid·Forchlorfenuron
About 15 days after the grapes withered flowers and the diameter of the fruit is 10-12 mm, the fruit ear can be soaked once with 15-30 mg/L 0.3% gibberellin·chlorfenuron solution, which can significantly improve the fruit setting rate and increase the fruit size. , to promote the rapid growth and development of fruit into commercial fruit, improve fruit shape.
6-BA·Gibberellic acid（GA4+7）
When the transverse diameter of young fruit is 12~14mm (about 20~25d after blooming), soak the ear with 40~50mg/L benzylamine·gibberellic acid (GA4+7) solution once, which can promote fruit setting and fruit growth and development, improve the Single fruit weight, early ripening and increased yield.
