Some studies have pointed out that the optimal ratio of nitrogen, phosphorus and potassium for Fujiminor grapes is 1:1.24:1.41, but it is not applicable to all natural conditions such as soil and climate (Li Chunhui, Effects of Nitrogen, Phosphorus and Potassium Application on Fujiminor Grape Yield and Quality[ D]. Jilin Agricultural University, 2013.)

Abstract

The invention discloses a special grape fertilizer applicable to wet soil and a preparation method and application. The special grape fertilizer consists of an organic fertilizer, urea, diammonium phosphate, potassium sulfate, borax and sodium molybdate in a certain ratio. The preparation method comprises the following steps: A, respectively crushing urea, diammonium phosphate and potassium sulfate; B, mixing the crushed urea, diammonium phosphate and potassium sulfate; C, pelletizing the mixture of urea, diammonium phosphate and potassium sulfate; D, gradually adding dense mix of yeast, tobacco stem powder, rice bran and powdery borax and sodium molybdate in the pelletizing process; E, drying, and screening, thereby obtaining a ternary composite fertilizer with organic matters and trace elements. The special fertilizer is used in wet soil grape cultivation, is reasonable in formula and good in use effect, and is capable of remarkably increasing the yield and improving the quality of grapes. The contents of soluble solids and vitamin C and solidity-acid ratios of grapes can be remarkably increased, and the content of titratable acids can be reduced. A best quality improvement effect can be achieved for Kyoho grapes.

Description

technical field [0001] The invention belongs to the technical field of fertilizer utilization, and more specifically relates to a special formula fertilizer for grapes suitable for fluvo-aquic soil, and also relates to a preparation method for a special fertilizer for grapes suitable for fluvi-aquic soil, and also relates to the application of a special formula fertilizer for grapes . Background technique [0002] Grape is one of the fruits with the largest planting area in the world, and its yield and quality directly affect economic benefits. High-yield and high-quality grapes not only require sufficient and comprehensive nutrient supply, but also need to add organic matter to the planting soil to fertilize the soil (Li Hua, Viticulture [M]. Beijing: China Agricultural Press, 2008.76-93, 2008). At present, the main problems of grape fertilization include that the large-scale application of chemical fertilizers leads to soil compaction, the decrease of soil organic matter ...
