Problems solved by technology

[0003] However, the seed shattering rate of this variety is serious after maturity (the shattering rate of super-sweet grapes cultivated in the prior art is as high as 25%, and 30% in severe cases), which discourages some high-end customers and large supermarkets and directly affects the economic benefits of the majority of growers.
However, there is no cultivation method disclosed to effectively reduce the shattering situation of super-sweet grapes

Embodiment 1

[0030] A cultivation method for alleviating super-sweet grape shattering, the concrete steps are as follows:

[0031] 1) Use 5BB rootstock to graft super sweet grape seedlings;

[0032] 2) Protected cultivation is carried out by means of protected cultivation, and biological fertilizers are applied during the cultivation period;

[0033] 3) V-shaped pruning is used to plant 500 plants per mu; the spacing between plants is 70 cm, and the row spacing is 190 cm;

[0034] 4) Topping 4-5 leaves before flowering, keeping only one auxiliary shoot for extension and growth, and erasing the rest of the auxiliary shoots; topping new shoots with 4-5 leaves, and new auxiliary shoots with 2-3 leaves;

[0035] 5) Spray 150 times of PBO solution on the 15th and 30th day of flowering respectively;

[0036] 6) When 75% of the flowers bloom, spray the fruit preservation agent; after the fruit preservation agent is sprayed, immediately water and apply high-nitrogen water to flush the fertilizer...

Abstract

The invention discloses a cultivation method for decreasing super sweet grape shattering, which belongs to cultivation technology field. The method comprises the steps of a. adopting 5BB stock to graft the super sweet grape sprouts; b. performing protective cultivation by using a protective cultivation way, and applying bio fungus organic fertilizer during the cultivation period; c. planting 400-600 grapes every Mu in V- pruning way; d. pinching before the florescence; e. spraying PBO foliar fertilizer during the florescence; f. spraying a fruit-keeping agent when the florescence comes to an end; g. dipping the clusters with an expansin within a month after the fruits come out, and thinning the fruits immediately after dipping the clusters; and h. putting a bag thereon. The invention discloses the key technology for decreasing super sweet grape shattering effectively in every stage based on the basic characteristics; and the measures for decreasing super sweet grape shattering at each stage are adopted so as to decrease shattering. Also, the economic benefit is greatly increased.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a cultivation method for alleviating grain shattering of super-sweet grapes. Background technique [0002] The super-sweet grape is a European and American hybrid variety. The natural fruit ears are double-shouldered and conical. The average ear weight is 1000g, and the largest ear weight is 3000g. The fruit is huge and round, with a grain weight of 12g~15g, and the maximum grain weight is 20g. The fruit is golden yellow after ripening, the flesh is thick, juicy and sweet, the flesh is tender and the rose fragrance is strong. The sugar content is as high as 25-28%. It has a good reputation in the local area and a relatively good sales market. It is currently the sweetest grape variety. [0003] However, the seed shattering rate of this variety is serious after maturity (the shattering rate of super-sweet grapes cultivated in the prior art is as high as 25%, and 30% in seve...
