Fertilizer specially used in fructescence of Muscat Hamburg grape variety

Abstract

The invention provides a fertilizer specially used in the fructescence of a Muscat Hamburg grape variety. The fertilizer comprises the following components in parts by weight: 15-25 parts of diammonium phosphate, 55-65 parts of potassium sulfate, 8-15 parts of calcium sulfate and 8-15 parts of lees organic fertilizers. The fertilizer has the following beneficial effects: the fertilizer is a mixture of organic and inorganic fertilizers; the content of total active nutrients of the fertilizer is more than 40%; applied in the veraison of the Muscat Hamburg grape varieties, the fertilizer can effectively promote color brightness of the grapes and increase fruit sugar; the disease resistance is improved, thus improving the quality of the grape variety; and meanwhile, the cost is reduced. The fertilizer is especially suitable for the soil similar to that in the Tianjin producing area.

Description

technical field [0001] The invention belongs to the field of fertilizers for grape planting, and in particular relates to a special fertilizer for the fruit ripening period of Muscat muscat grape varieties. Background technique [0002] Muscat grapes are both edible and wine-making varieties. Muscat grapes are native to the UK and are a mid-to-late-maturing Eurasian species. This variety has a strong aroma, high sugar-acid ratio, delicious taste, and excellent quality. It is an excellent variety for both fresh food and brewing. In my country, the famous producing areas of muscat grapes are mainly concentrated in Hangu, Tianjin, Changli, Hebei, Dazeshan, Shandong and other places in the Bohai Bay area. Among them, Hangu, Tianjin is the most famous. One, the dry white and semi-dry white wines brewed from it have also won international gold medals for many times, reflecting typical regional characteristics. [0003] Soil is the basis for the survival and development of grape ...

AI Technical Summary

Problems solved by technology

The production area of ​​Tianjin belongs to the warm temperate zone semi-humid continental monsoon climate, with four distinct seasons. The soil parent material is rich in calcium carbonate, the lime reaction is strong, and it is rich in iron and manganese nodules. Alkaline clay, rich in organic matter, potassium and trace elements, alkaline soil, poor air permeability and thermal conductivity, strong adsorption; strong phosphorus fixation, poor availability; cold soil, late germination of grapes

[0004] Muscat grape varieties have moderate or strong tree vigor, good yield, and strong salt-alkali resistance, but they have high requirements for fertilizer and water in the soil. Insufficient nutrients are prone to flower drop, fruit drop, and large and small grains, and are also prone to physiological diseases. , seriously affecting the yield and quality of grapes

In actual production, due to the different development periods of muscat grapes, the types and proportions of fertilization are unreasonable according to the soil conditions in different regions, resulting in insufficient nutrition, which affects the final grape yield and quality, and farmers have high yields but not good harvests. The phenomenon
