Special fertilizer for grapes as well as preparation method and application method thereof

Abstract

The invention provides special fertilizer for grapes. The special fertilizer is prepared from the following components in percentage by weight: 1 percent to 2 percent of potassium dihydrogen phosphate, 15 percent to 20 percent of monoammonium phosphate, 8 percent to 15 percent of potassium nitrate, 25 percent to 30 percent of ammonium sulfate, 1 percent to 2 percent of resin-coated urea, 10 percent to 15 percent of sulfur-coated compound fertilizer, 2 percent to 5 percent of nitrogen phosphorus potassium compound fertilizer, 10 percent to 15 percent of film-coated potassium sulfate, 10 percent to 15 percent potassium sulfate, 1 percent to 2 percent of an organic sustained-release agent and 1 percent to 2 percent of microelement fertilizer. The special fertilizer for the grapes, provided by the invention, has diversified and comprehensive nutrients, and rapid effect is combined with sustained release, so that nutrient elements needed by normal growth of the grapes can be provided and stable production and high yield of the grapes can be ensured; the invention further provides a preparation method and an application method of the special fertilizer for the grapes; when the special fertilizer for the grapes is applied, the aims of saving cost and increasing the effect can be realized and nutrient loss caused by excessive fertilization or accustomed fertilization and influences on the environment are alleviated.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to a special fertilizer for grapes, a preparation method and an application method thereof. Background technique [0002] Since my country's reform and opening up, the grape industry has developed rapidly. According to statistics from the International Organization of Vine and Wine (OIV), China's grape planting area has reached 11.508 million mu in 2014, with an output of 12.546 million tons and a wine output of 1.161 billion liters. China has surpassed France is the second largest grape growing country in the world. China's grapes are developing rapidly. Although there are positive aspects, there are also many problems, especially in the field of grape fertilization. [0003] Grapes can be planted in both the north and the south of our country. At present, grape fertilization mainly uses base fertilizer and top dressing. The base fertilizer is applied into the soil in autum...

AI Technical Summary

Problems solved by technology

Due to the high requirement of nutrient supply in grape production, the current farmers have little scientific knowledge, blind fertilization or experience fertilization is too much, causing many problems

First, nutrient allocation is unreasonable, fertilization is generally single, and predatory production and fertilization lead to an extreme lack of soil organic matter and trace elements; second, fertilization methods are unscientific, and most farmers are still blindly imitating the time and method of fertilization, resulting in nutrient deficiency. The supply is not timely or the nutrient utilization rate is not high; the third is that most fertilization methods such as ditching are used, which can easily cause root damage, root breakage, or even root burning, affecting nutrient absorption and tree vigor
