Description
Technical Field
The invention relates to a composition for promoting coloring and sweetening of grapes, and belongs to the technical field of fruit and vegetable fertilizers.
Background
Under the conditions of high yield of grapes, small temperature difference between day and night and low temperature, fresh grapes such as Kyoho grapes and ruby grapes are difficult to color, and the problem that the coloring is difficult to solve in production is one of the difficult problems. The good and bad color of the grape fruits has important influence on the appearance quality and the nutritional quality of the fruits and also is an important embodiment of the good and bad commodity of the fruits. Therefore, the promotion of fruit coloring and the improvement of fruit appearance have recently been receiving attention from growers.
In order to better color the grapes, the prior method not only strengthens cultivation management, improves tree body illumination conditions, covers bags, picks leaves, turns fruits, reasonably loads, reasonably applies fertilizers and other measures, but also mainly uses the components of foliar fertilizer monopotassium phosphate, anthocyanin precursor substances, phytohormone abscisic acid, ethephon, jasmonic acid lactone and the like to spray leaves or fruits in the production.
However, although the monopotassium phosphate is safe and has no side effect when sprayed to leaves, the sugar degree of fruits can be improved, but the coloring is slow; the anthocyanin precursor has high safety, better coloring effect than potassium dihydrogen phosphate, but can not improve the taste, relatively slow coloring and high price cost; the abscisic acid is used as the main component of the abscisic acid, the coloring is faster, the sugar degree of fruits is not reduced, the fruit grains are not softened, but the coloring is uneven when the abscisic acid is improperly used, the fruit grains are easy to fall off when the abscisic acid is excessively used, the coloring can be promoted, and the ripening cannot be promoted; the coloring agent taking ethephon as a main component is quick to color, is sprayed by blades, is convenient to use and uniform in coloring, but is easy to cause blade aging, water tank diseases are easy to cause due to too early use or too many times, and particle falling is also caused due to too high concentration, so that the storage quality of grapes is influenced; the coloring agent using jasmonic acid lactone as a main component is safe to use, does not influence the taste, does not fall off grains, but has relatively slow coloring speed and higher cost.
In conclusion, many colorants used in the prior production need not be colored slowly, have unobvious effects and are not easy to cause side effects, so that a new environment-friendly, safe, efficient, nontoxic, economical and convenient way needs to be found, the appearance of the fruits is improved, the coloring is uniform, the internal quality of the fruits is improved, such as the taste is improved, the sugar degree is improved, the storage performance of the fruits is maintained, and the fruits do not fall off or fall off during transportation. Under the condition of meeting the requirements, the fruit preservative also needs to ensure safety, no toxicity, no harm to human bodies and no damage to fruits.
