Seedless treatment method of Zuijinxiang grapes

Abstract

The invention discloses a seedless treatment method of Zuijinxiang grapes. The seedless treatment method of Zuijinxiang grapes sequentially comprises the following steps of: (1) slightly pinching young sprouts, picking flower spikes and pruning the inflorescences 1 to 2 days before a Zuijinxiang grape vine flowers, and keeping 5 to 6 centimeters of the spike tips; (2) carrying out primary seedless treatment on the Zuijinxiang grape vine 1 to 2 days after the bloom stage: dipping the inflorescences in a treating agent I (containing gibberellin solution with the concentration of 12.5 to 20.0mg.L<-1>) for 3 to 5 seconds; and (3) carrying out secondary seedless treatment within 10 to 15 days after the primary seedless treatment: dipping the inflorescences in a treating agent II (containing gibberellin solution with the concentration of 20.0 to 25.0mg.L<-1>) for 3 to 5 secodns. The seedless treatment method of Zuijinxiang grapes can be adopted for obtaining high-quality Zuijinxiang seedless grapes.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a seedless treatment method for Drunken Grapes. Background technique [0002] With the continuous improvement of living standards, people pay more and more attention to the safety of products while pursuing food diversity. More and more people pay more and more attention to the influence of the processing method of seedless grapes on product quality and safety. In addition, grapes are a high-input and high-yield tree species, especially in the high-temperature and rainy environment in the south. How to reduce costs while ensuring quality is a major issue worth noting. Therefore, the development of large-grain, seedless, high-quality and labor-saving production technologies plays a very important role in grape production. [0003] Zuijinxiang, also known as jasmine fragrance, is a hybrid of Shenyang rose and Kyoho in the Horticultural Research Institute of Liaoning Academy...

AI Technical Summary

Problems solved by technology

Existing problems: easy to produce stiff fruit, unstable yield, large amount of labor for fruit thinning, and difficult cultivation; fruit stems are thick and hard, and ripe fruit is easy to shatter during harvesting, transportation, and sales; the cost of chemicals is high, per 667m 2 The garden costs about 180 yuan; the mature fruit has a strong astringent taste and hard flesh

The results of the experiment are: Zuijinxiang grapes are sensitive to piribolone, gibberellin and Yiguolin. After three days after flowering and 15 days apart, the seedless rate reached 100% after two treatments alone or in combination, and the fruit size increased. The effect is obvious, but the quality of the fruit is not good, which is specifically manifested in: the sugar content is reduced, and the fruit powder on the surface of the peel is reduced

[0007] In addition, the existing conventional practice in the early stage does not specify the degree and specific location of the thinning of flower spikes. Instead, the middle section is left, resulting in uneven flowering time and serious fruit size, which increases the workload of fruit thinning in the future.

Wang Huaxin et al. (2007) informed that 10 days before flowering, hormone treatment was used to elongate the flower spikes, and the top 4 leaves of the flower spikes were strongly topped; this would easily increase the amount of stiff fruit and the workload of picking secondary shoots later, and increase the cost.
