Seedless processing method for culturing Pione grape in open field

Abstract

The invention discloses a seedless processing method for culturing Pione grape in an open field. The method comprises the following steps: arranging flowers and spicae from five days before flowering to the initial flowering stage; thinning auxiliary spicae and branches at both ends of the upper parts of the spicae, wherein fruit spicae with the lengths of 3.5-4.0cm at the tops of the flower spicae and 14-15 branches are maintained; during 50-100% of the flowering period of the flower spicae, carrying out spica dipping treatment with gibberellin and/or forchlorfenuron liquid for the first time, and two weeks later, carrying out spic dipping treatment with forchlorfenuron liquid for the second time; emphasizing the prevention and control of diseases and insect pests from the blooming period of grape scalebud; and maintaining 30-35 fruits on each spica after picking. Through the method, fruits with good quality can be obtained, the color is completely purple black, the spicae and grains are regular, the taste is sweet, the weight of single grape reaches 15.0g, the average weight of fruit spica is 500g, the content of soluble solids is 16-18%, and the yield per mu is 1100kg; the seedless degree is high, which is 96.6% at most; moreover, the difference of fruit maturation period of Pione grape and the fruit maturation period of Kyoho grape is 5-10 days so that more production choices can be provided for producers without causing overstocking of product during a certain period of time.

Description

technical field [0001] The invention relates to the field of fruit cultivation, in particular to a seedless treatment method for pioneer grapes cultivated in the open field. Background technique [0002] Grape is the main fruit tree species in my country. Due to the high benefits of grape planting, grapes have been included in the local pillar industry in some areas. Grape planting has played an important role in revitalizing the rural economy and enriching farmers in various places. Therefore, grapes in southern my country are developing rapidly. , but because the planted varieties are still mainly Kyoho and Fujiminori, the variety is single, and the concentrated fruit maturity period has brought great pressure on the sales of grape growers, resulting in damage to the product backlog; the quality is single, and the concentrated supply period can no longer satisfy consumer needs. The production of grapes has begun to disconnect from the needs of consumers. Now people are beg...

Problems solved by technology

Now people are beginning to explore the field of seedless grapes, focusing on the seedless treatment of early-maturing grapes, but the fruit grains of early-maturing grape varieties are relatively small, and the cultivated seedless grapes are not full and sweet.

[0003] On the other hand, some existing grape seedless treatment methods are too complicated, and the seedless agents used are
