Grape fertilization method

Abstract

The invention discloses a grape fertilization method mainly for grape vines which are 3 years and above aged. The grape fertilization method includes a base fertilizer application stage and a topdressing application stage; the base fertilizer application is mainly intended for a second growth peak of autumn grape roots; the topdressing application is mainly intended for a germination stage, an early flowering stage, a berry swelling stage, a berry coloring stage and the like, reasonable fertilization is performed in each stage to ensure required nutrients of each grape growth stage, and grapequality is guaranteed accordingly. The grape fertilization method for grape vines which are 3 years and above aged combines reasonable fertilization and key stage fertilization; evident effect improvement is provided for grape in south which has low sweetness due to rainy seasons; the method herein ensures grape sweetness and improves grape quality, can prevent grape fruit softening and extend storage and transport period of grape, well as shelf life of grape; soil acid-base property can be reasonably adjusted, disease resistance of grape vines can be enhanced, and otherness can also be achieved. Therefore, the grape fertilization method is simple, efficient and highly operable.

Description

technical field [0001] The invention belongs to the technical field of viticulture, and in particular relates to a grape fertilization method. Background technique [0002] Grape is one of the oldest fruit tree species in the world. It is rich in nutritional value and is a very nourishing fruit. Grape juice is known as "vegetable milk" by scientists. Grapes contain protein, carbohydrates, crude fiber, calcium, phosphorus, iron, potassium and other trace elements, as well as carotene, vitamin B1, vitamin B2, vitamin C, vitamin P, vitamin PP, etc. More than ten kinds of amino acids and a large amount of fruit acids. Grapes have high sugar content, mainly glucose, and can be eaten raw or made into raisins, and made into wine.

Problems solved by technology

[0003] Traditional planting techniques generally believe that deep roots and luxuriant leaves are the best state for plant growth, so most of them use deep plowing, more fertilization, and frequent watering. However, this will easily lead to excessive growth of the tree itself, excessive flowering, severe flower and fruit drop, and overall Problems such as low output and quality make the economic benefits unsatisfactory

Moreover, the south of my country is still in a rainy area, and unreasonable fertilization will not only affect the yield and quality of grapes (more rain will promote the vigorous growth of crops on the one hand, leading to lodging of crops, and on the other hand lead to loss of soil nutrients, etc.), it is also easy to cause Damage to soil and water bodies
