Special soluble formula fertilizer for grapes and application method thereof

Abstract

The invention discloses a special soluble formula fertilizer for grapes and an application method thereof. The formula fertilizer comprises a fertilizer a, a fertilizer b and a fertilizer c, wherein the fertilizer a consists of carbamide, diammonium phosphate, potassium sulfate, zinc sulfate and borax; each of the fertilizer b and the fertilizer c consists of carbamide, diammonium phosphate and potassium sulfate; the components are matched according to a required proportion. The method comprises the steps as follows: firstly, the fertilizer a, the fertilizer b and the fertilizer c are respectively prepared into solutions with the weight percentage of 0.2-0.3%; secondly, utilizing the fertilizer a to conduct drip irrigation before the florescence; thirdly, utilizing the fertilizer b to conduct drip irrigation after the florescence; fourthly, utilizing the fertilizer c to conduct drip irrigation at the initial stage of coloring. According to the formula fertilizer and the application method thereof, the fertilization is implemented with pertinence completely according to the proportion of the nutrients required by the grapes at various growing periods so as to achieve the aims of cost saving, quality improving and efficiency improving; the defects that the matching of the ordinary compound fertilizer is not scientific and the cost of the ordinary soluble fertilizer is high are overcome; moreover, root drip pipes or irrigation are adopted for topdressing, so that the fertilizer effect can be taken quickly, and the labor cost is reduced.

Description

[0001] technical field [0002] The invention relates to the field of viticulture, in particular to a special soluble formula fertilizer for grapes and an application method thereof. Background technique [0003] At present, the area of ​​grape cultivation in my country is increasing continuously, and the output is increasing steadily. Whether in the north or the south, the grape industry is developing very rapidly. At present, grapes are planted in 31 provinces (municipalities, autonomous regions) across the country. Among the 58 grape-producing countries in the world, my country's grape cultivation area and output have leapt to the fifth place, especially fresh table grapes. my country has become the world's largest. Producing countries. my country's grape production technology is also constantly improving, but grape fertilization, especially topdressing, is relatively random, and the amount of topdressing accounts for 40-50% of the total amount of fertilizer. Insufficien...

Problems solved by technology

my country's grape production technology is also constantly improving, but grape fertilization, especially topdressing, is relatively random, and the amount of topdressing accounts for 40-50% of the total amount of fertilizer. Insufficient potassium ratio and other problems, especially the gradual application of fertilizer-water integration technology, topdressing fertilizers are required to be soluble, and there are many and miscellaneous soluble fertilizers on the market, but soluble fertilizers for grape topdressing are rare, and most soluble fertilizers are not available. Consider the characteristics of different nutrient requirements of grapes in different growth periods
