How to increase Kyoho grape fruit setting rate
The Kyoho grape is very plentiful and very popular with consumers. However, there are weaknesses in the low fruit setting rate in cultivation. Practice has shown that taking the following five measures can increase Kyoho's Portuguese fruit set rate. First, artificial pollination. In the early days of full bloom, on a sunny morning, after the dew has dried, gently twist the wire to artificially pollinate the grapes. Second, foliar spray boric acid, urea mixture. The supplementation of 0.2% boric acid and 0.3% urea in each of the first 10 days before flowering and the initial flowering period can significantly increase the fruit setting rate. Third, reasonable sparse flower. Seven to ten days before flowering, the inflorescences are reshaped and excess flowers are removed. The method of inflorescence shaping is to cut 1/4 or 1/5 of the tip of the inflorescence and remove the poorly differentiated spikelets. The method of sparse flowering is: Strong branches (the thickness between the 4th and 5th section is below 0.7 cm) can leave two inflorescences, generally the fruit branches leave one inflorescence, and the weak branches do not stay. Fourth, the results of the branch topping. It begins 5 to 6 days before flowering. Picking up the standard: It is advisable to pick up leaves that are 1/3 of the size of the leaves, and to wipe out all the secondary tips that are emitted. Fifth, flowering girdling. Flowering at the base of the resulting branch or resulting mother branch can also increase fruit setting.
