Problems solved by technology

[0003] At present, there are many types of calcium and boron fertilizers used in grape production, and there is a lack of precise technical solutions for calcium and boron nutrition supplementation. Calcium and boron are used blindly and indiscriminately. For grape vines and fruits, calcium and boron supplementation The effect is poor, and the effect of improving grape fruit quality is uneven
[0004] There are two main problems in the existing calcium and boron application: 1. Improper application time, unable to grasp the critical period for grapes to absorb calcium and boron; 2. Improper application concentration, mainly manifested as blindly increasing the dosage, but antagonism or poisoning

Embodiment 1

[0042] For varieties with poor fruit setting rate: such as Kyoho varieties, spray the mixed solution A once on the grape leaves 15 days before flowering and 7 days before flowering; spray mixed solution B once when the young fruit expands; Spray mixed solution C or mixed solution D once during the fruit color change period, and spray 4 times in total on the leaves.

Embodiment 2

[0044] For varieties with good fruit setting rate but easy to crack fruit: such as Guifei rose grape, spray mixed solution B once on the leaves of young fruit during the expansion stage; spray mixed solution C or mixed solution D once on the fruit during the fruit color change period; Two weeks before harvest, spray the mixed solution C or mixed solution D once on the leaves, twice on the leaves, and once on the fruit, a total of three times.

Embodiment 3

[0046]For grapes with good fruit setting rate and storage and transportation requirements: such as Red Globe grapes, spray mixed solution B once on the foliage during the young fruit expansion stage; spray mixed solution C or mixed solution D once on the fruit during the fruit color change period ; Two weeks before the harvest, the fruit was sprayed once with mixed solution C or mixed solution D, the leaves were sprayed once, and the fruit was sprayed twice, a total of 3 times.

Abstract

The invention relates to a leaf surface application method for supplementing boron and calcium elements to grapes. The method includes the steps that spraying is conducted 15 days before grape flowering, 7 days before flowering, in a young fruit expanding period, in a coloring period and 2 weeks before harvesting. A foliar fertilizer is prepared by taking mixed solution of xanthan gum and rhamnolipid as base solution, wherein the mass concentration of the xanthan gum is 2-8%, and the mass concentration of the rhamnolipid is 1-4%. According to the leaf surface application method for supplementing the boron and calcium elements to the grapes, grape spica formation is guaranteed, the fruit setting rate is increased, fruits are expanded, the fruit hardness and the fruit surface gloss are improved, and the stress resistance of the grapes and the quality of grape products are integrally improved. In addition, a product and the method adopted can well prevent and treat white rot.
