Fertilizer for improving root activity of Merlot grape variety

Abstract

The invention provides fertilizer for improving root activity of a Merlot grape variety. The fertilizer is prepared from the following components in part by weight: 8 to 12 parts of monopotassium phosphate, 10 to 15 parts of urea, 5 to 10 parts of calcium sulfate, 3 to 5 parts of zinc sulfate, 3 to 5 parts of manganese sulfate, 3 to 5 parts of borax and 48 to 68 parts of wine lees organic fertilizer. The nutrient elements in the fertilizer are matched reasonably; after Merlot grape plants are harvested, the fertilizer is applied timely; and the root activity is promoted effectively, the rooting capacity of the plants is improved, and the total root amount is increased by 10 to 15 percent, so that the growth of the overground parts of the plants are promoted, the yield and the quality of grape berries are improved comprehensively, the yield is improved by 10 percent, the sugar content is improved by 8 to 12 percent, and the phenomena of low root activity and rooting capacity of the Merlot grape plants are improved.

Description

technical field [0001] The invention belongs to the field of crop nutrition agents, and in particular relates to a fertilizer for improving the root activity of merlot grape varieties. Background technique [0002] Due to its outstanding quality, the wine grape variety Merlot has been widely valued by people in the international wine industry, and it has become one of the red wine varieties with the fastest growing planting area in the world. In recent years, with the rapid growth of dry red wine consumption, the planting area of ​​Merlot varieties in various regions of the country has been continuously expanding. However, in the planting areas of the Merlot grape variety, some plants of this variety began to grow abnormally in the spring of the second year after planting. The economic loss was serious, and other varieties had to be replanted. [0003] Merlot variety characteristics are the root cause of its spring disease. It belongs to the horizontal development of the r...

Problems solved by technology

The small amount of roots also results in less stored nutrients and poor overwintering ability; at the same time, because the plant growth in spring is in the transition period from storing nutrients to relying on the photosynthetic products and active hormones produced by the branches and leaves of the year (this period is also a nutritional critical period) , the lack of storage nutrients intensifies the nutrient competition and the interruption of material connection during the conversion period. Therefore, merlot varieties are prone to nutrient stress earlier than other varieties

[0006] The variety has poor rooting ability, new roots, especially absorbing roots, are less likely to occur, and unfavorable factors cause most of the root tips to die, resulting in less production of cytokines and less nutrient absorption (hormone production and nutrient absorption are mainly completed by the root tips). , water stress also aggravates the difficulty of root system absorbing nutrients
