Problems solved by technology

[0002] Kyoho is the main grape variety in my country, but there is a problem of falling flowers and fruits in the open field cultivation of Kyoho. If the seedless cultivation is used in the open field, Kyoho can be seedless, with beautiful ear shape and good taste. However, due to the expansion of Kyoho fruit, it coincides with mold In the rainy season, the rainfall is heavy, and the moisture in the vineyard changes greatly, which leads to the cracking of the kyoho fruit in seedless cultivation, destroying the ear shape, and resulting in a decrease in yield
The existing Kyoho grape seedless cultivation method is easy to cause serious fruit cracking, the incidence rate of fruit cracking is as high as 25%, and the cracking results in a serious reduction in grape production, with an output of about 750 kg per mu, and the fruit is swollen. Uneven greenness, poor appearance of the grapes

Embodiment 1

[0017] A method for preventing fruit cracking in the open-field seedless cultivation Kyoho grape includes the following steps:

[0018] 1) From 7 days before the flowering of Kyoho grapes to the first flowering stage, the flower spike is reshaped, the side spikes of the flower spike and some of the uppermost stalk spikelets are removed, and the lower stalk spikelets of the flower spikes are retained, and the flowers with the stalk spikelets are inserted. The cob length is 3 cm, and the cob length of the stalk florets does not exceed 2 cm, and the part exceeding 2 cm is retracted;

[0019] 2) When the grapes bloom 100%, the flower ears shall be soaked with 15ppm gibberellic acid for seedless treatment, and the ears shall be soaked with 25ppm gibberellic acid and 2.5ppm for chlorfenuron at an interval of 10 days, and one ear shall be selected for each new shoot with moderate growth. If the fruit set is uniform, the size of the fruit is basically the same, and the ears of the ears are...

Embodiment 2

[0026] 1) From 7 days before the flowering of Kyoho grapes to the first flowering stage, carry out flower spike shaping, remove the auxiliary spikes of the flower spikes and several stalk spikelets at the top, and retain the stalk spikelets at the lower part of the flower spike and the flowers with the stalk spikelets. The length of the cob is 4 cm, the length of the cob of the branch stalks does not exceed 2 cm, and the part exceeding 2 cm is retracted;

[0027] 2) When grapes are 100% blooming, the flower ears shall be soaked with 20ppm gibberellic acid and seedless treatment, 15 days apart, the ears shall be soaked with 15ppm gibberellic acid and 5ppm for chlorfenuron to expand. Each new shoot with moderate growth is selected to leave one ear and set fruit Remove the remaining ears if the ears are even, the size of the fruit is basically the same, and the ears are better;

[0028] 3) At the end of setting the ears, the fruit should be thinned in time to produce high-quality seed...

Embodiment 3

[0034] 1) From 7 days before the flowering of Kyoho grapes to the first flowering stage, the flower spike is reshaped, the side spikes of the flower spike and some of the uppermost stalk spikelets are removed, and the lower stalk spikelets of the flower spikes are retained, and the flowers with the stalk spikelets are inserted. The length of the cob is 3 cm, the length of the cob of the branch stalks does not exceed 2 cm, and the part exceeding 2 cm is retracted;

[0035] 2) When the grapes bloom 100%, the flower ears shall be soaked with 25ppm gibberellic acid for seedless treatment. At 13 days interval, the ears shall be soaked with 20ppm gibberellic acid and 3.75ppm for chlorfenuron to expand, and one ear shall be selected for every new shoot with moderate growth. If the fruit sets are even, the size of the fruit is basically the same, and the ears with better ears and ears, remove the remaining ears;

[0036] 3) After setting the ears, the fruit should be thinned in time to pro...

Abstract

The invention discloses a method for preventing outdoor seedless cultivated Kyoho grapes from cracking. The method comprises the steps of carrying out spike shaping during an initial flowering stage; carrying out seedless treatment during a full-bloom stage; immersing fruit clusters in gibberellic acid in 10-15 days after the full-bloom stage and carrying out expansion treatment on the fruit clusters by adding forchlorfenuron in the gibberellic acid; then fixing the fruit clusters and timely carrying out fruit thinning; covering a white mulching film on the ground after grapes are bagged, wherein relatively stable water in a grapery is ensured, fruits can gradually grow bigger and bigger, and grape fruits can be prevented from cracking. According to the method disclosed by the invention, through standard management such as spike shaping, fruit cluster fixing, fruit thinning, bagging by dedicated grape bags and shoot pinching, the adnation of fruits is uniform, the fruit clusters are gorgeous in appearance, the grape yield is stabilized, and the grape quality is increased.

Description

Technical field [0001] The invention belongs to the field of grape planting, and in particular relates to a method for preventing fruit cracking in the open field seedless cultivation Kyoho grape. Background technique [0002] Kyoho is the main grape variety in my country, but the open field cultivation Kyoho has the problem of falling flowers and fruit. If the open field is cultivated without seeds, the Kyoho can be seedless, the ear shape is beautiful, and the taste is good. During the rainy season, heavy rainfall and large moisture changes in the vineyards caused the seedless cultivation Kyoho to crack the fruit, destroy the ear shape, and reduce the yield. The existing Kyoho grape seedless cultivation method is likely to cause serious fruit cracking. The occurrence rate of fruit cracking is 25%. The fruit cracking causes a serious reduction in grape production. The yield per mu is about 7.5 kilograms, and the fruit grains. Uneven growth and poor appearance of grapes. Summary...
