A product for improving grape root activity in secondary salinized soil

Abstract

The invention discloses a product for improving the vitality of grape roots in secondary salinized soil. The product includes the following components by weight: 12-15 parts of potassium dihydrogen phosphate; 11-16 parts of urea; 6 parts of potassium humate; 3-5 parts of liquid polyglutamic acid; 2-5 parts of tryptophan parts; Vitamin B 12 1 to 4 parts; 25 to 30 parts of molasses fermentation liquid; 25 to 30 parts of water. The invention can be applied to saline-alkali soil or secondary salinized soil, can effectively promote the formation and growth of roots, enhance the rooting ability of plants, increase the total amount of roots by 15.7-21.2%, protect root hairs, and reduce the impact of soil salt on the root hair area Especially root tip stress prolongs capillary root life.

Description

technical field [0001] The invention relates to a product for improving the vigor of grape roots in secondary salinized soil, and belongs to the technical field of fertilizer preparation. Background technique [0002] Grape, as an important economic crop, has become a pillar industry in many areas of our country, and has played an important role in helping the majority of growers get rid of poverty and become rich. Due to the high purchase price of grapes in the market, the net income per mu has reached 30,000 yuan or even higher, and farmers are highly motivated to plant. In recent years, the country's grape planting area and output have increased year after year. As of 2018, my country's grape planting area has exceeded 13 million mu, and the output has reached 13.083 million tons. In order to pursue high yield one-sidedly, high-intensity and excessive use of chemical fertilizers in viticulture are extremely common. Wang Tankui, Zhang Lijuan and others found that the inp...

Problems solved by technology

Due to the excessive use of chemical fertilizers, soil compaction, acidification and secondary salinization are intensified, the growth of grape roots becomes poor, the root tips are necrotic, the number of new roots is small, the survival life of root hairs is shortened, and the rate of nutrient absorption and utilization is reduced.

Although the amount of fertilization is increasing, the vine body is weak, the fruit setting is declining, the phenomenon of yellow leaves and small leaves is prominent, the color of the fruit is slow, and there are many dry branches, which seriously affects the development of the grape industry.
