Fertilizer for wine grape

Abstract

The invention provides a fertilizer for a wine grape, and belongs to the field of the fertilizers. The fertilizer for the wine grape comprises a germination period fertilizer, a blossom flowering and fruit bearing period fertilizer, a fruit swelling period fertilizer, a mature period fertilizer and a nutrition storing period fertilizer, wherein in parts by weight, the germination period fertilizer comprises 5-6 parts of nitrogen, 1.5-2.5 parts of phosphorus pentoxide and 3-4 parts of potassium oxide, the blossom flowering and fruit bearing period fertilizer comprises 1-2 parts of nitrogen, 1-1.5 parts of phosphorus pentoxide and 1-2 parts of potassium oxide, the fruit swelling period fertilizer comprises 4-4.5 parts of nitrogen, 6-6.5 parts of phosphorus pentoxide and 5-5.5 parts of potassium oxide, the mature period fertilizer comprises 4-5 parts of nitrogen, 2-3 parts of phosphorus pentoxide and 6-7 parts of potassium oxide, and the nutrition storing period fertilizer comprises 3-4 parts of nitrogen, 1-3 parts of phosphorus pentoxide and 5-6 parts of potassium oxide. The fertilizer for the wine grape achieves the effect that the grape in different growth periods can be fertilized correspondingly, and the growth and the yield of the grape can be promoted and increased obviously.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a fertilizer for wine grapes. Background technique [0002] Grapes are one of the four major fruits in the world. Not only has a beautiful flavor, but also contains a variety of nutritional elements that are beneficial to the human body, such as vitamins, organic acids, and proteins. Grapes are also widely used. In addition to being eaten fresh, they can also be made into wine, processed into raisins, and canned. my country's total grape production accounts for 34.7% of the world's total grape production, increasing from 2.358 million tons in 1998 to 10.543 million tons in 2012. At present, 70-80% of the world's grape production is used for wine making, while the area and production of wine grapes in my country account for more than 90% of the country's total. [0003] In the production of wine grapes, fertilization is one of the main factors related to economic and environmental be...

Problems solved by technology

For example, in the process of fertilization, the proportion of fertilizer nutrients used is not coordinated, and topdressing with the same nutrients is often used in different growth periods of grapes, and wine grapes have different requirements for the same nutrients in different growth periods. The use of topdressing with the same nutrients in different growth periods of wine grapes will often result in the lack or excess of nutrients in a certain growth period of wine grapes, which will directly have a harmful impact on the yield and quality of grapes
