Sunrose grape flower/ fruit cluster pruning method

Abstract

The invention discloses a sunrose grape flower / fruit cluster pruning method. The method for processing each flower / fruit luster includes the following steps that firstly, a flower cluster is pruned in a flower early stage, only a cluster top which is 3.5cm to 5cm long is reserved and the rest of small flower clusters on the flower cluster are cut off; secondly, the sizes of the fruit clusters are adjusted, on the fifteenth day after blooming, the fruit clusters are pruned so as to make the size of the fruit clusters uniform and effectively adjust the capacities of plants; thirdly, fruit thinning is carried out; fruit thinning is usually carried out 16 days to 20 days after blooming and the overall fruit remaining capacity of each fruit cluster is controlled to be within 32 to 53; fourthly, the capacities are adjusted; one month after blooming, two strings of fruit clusters are reserved on a young shoot which is more than 100cm long, one string of fruit clusters are reserved on a young shoot with the length ranging from 50cm to 100cm and no fruit clusters are left for a young shoot with the length less than 50cm. By means of the method, the weight of each fruit can be 12g to 15g and the yield of each fruit cluster ranges from 500g to 650g.

Description

technical field [0001] The invention relates to the field of agricultural technology, and in particular to a method for shaping and pruning the flower spikes and fruit ears of Sunshine Rose grapes, including flower spike shaping and fruit thinning of 'Sunshine Rose' grapes. Background technique [0002] 'Sunshine Rose' grape is a new variety bred by the Japan Fruit Research Institute by crossing 'Anyunjin 21' and 'Bainan'. The peel is yellow-green, the weight of a single fruit is 12-4 grams, and the sugar content is above 19%. The fruit can be eaten with the skin on, easy to cultivate without seeds, has a strong musky flavor, and is resistant to storage. It is a variety that has been vigorously promoted in Japan in recent years and introduced to my country. Later, it was planted in many areas, but the relevant supporting cultivation techniques have not been reported yet, and some traditional techniques are still generally used. For example, not paying attention to the flower...

AI Technical Summary

Problems solved by technology

The peel is yellow-green, the weight of a single fruit is 12-4 grams, and the sugar content is above 19%. The fruit can be eaten with the skin on, easy to cultivate without seeds, has a strong musky flavor, and is resistant to storage. It is a variety that has been vigorously promoted in Japan in recent years and introduced to my country. Afterwards, it was planted in many areas. At present, the supporting cultivation techniques have not been reported. Generally, some traditional techniques are still used.

For example, not paying attention to the flower spike shaping work before flowering, resulting in uneven flowering time, serious fruit size and grain size, increasing the workload of fruit thinning afterwards, etc.

During the production process, it was found that 'Sunshine Rose' grapes had many badly shaped flower spikes and the cobs were bent; during flowering, the flower spikes elongated and grew, and the fruit grains at the apex were poorly set, and the removal of the spike tips would increase the lateral growth of the spikes, giving 'sunshine Roses' stable fruit set and appearance quality posed difficulties for production

At present, these problems for this variety have not been reported in the literature. Therefore, solving the flower spike shaping before flowering and the fruit thinning method after fruit setting plays a very important role in the production of high-quality grapes.
