Composition for growth regulation of underground rhizome type crops

Abstract

The invention belongs to the technical field of crop cultivation, and particularly relates to composition for growth regulation of underground rhizome type crops. The composition comprises effective components in parts by weight as follows: 1.0-30.0 parts of prohexadione calcium, 1.0-30.0 parts of hymexazol, 0.5-10.0 parts of diethyl aminoethyl hexanoate, 0.5-10.0 parts of naphthylacetic acid and1.0-30.0 parts of amino acid; the composition further comprises 10.0-96.0 parts of auxiliary materials. The composition is prepared in acceptable forms of pesticides. The composition is used for regulating growth of overground parts of plants and promoting growth of underground parts, so that the purposes of increasing yield, improving agricultural product quality and enhancing stress resistance can be achieved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a composition for regulating the growth of underground rhizome crops. Background technique [0002] Garlic, onion, radish, potato, sweet potato and other underground root crops are important agricultural cultivars in my country. They are edible or used for seasoning. They mainly feed on their underground roots or stems, and are very popular among the public. In recent years, the planting area of ​​underground rhizome crops has shown a tendency to expand. Although the soil cultivation conditions and field management measures have been continuously optimized, due to the unreasonable use of pesticides and chemical fertilizers, the nutrient input of crops has been seriously out of balance, making its output reach the bottleneck stage and cannot be sustained. growth, or even a downward trend. At the same time, a large amount of pesticides and chemical fertilizers...

AI Technical Summary

Problems solved by technology

The second is to accelerate the speed of cell division. The commonly used ingredients are naphthaleneacetic acid, sodium binitrophenolate, etc. These regulators are not safe and are sensitive to certain crops or a certain growth period. Excessive application is prone to phytotoxicity; the third is to strengthen nutrition. For material supply, the commonly used ingredients are nitrogen, phosphorus and potassium macroelement fertilizers, etc. After application, it is easy to cause plants to become green and late-maturing, and the yield of underground rhizomes and fruits is low, and fertilization does not increase production.

[0005] To use these existing products correctly, it is necessary to determine the reasonable dosage according to the growth of the plants. However, in actual use, due to the unevenness of farmers' pesticide application techniques, in the process of spraying pesticides, the dosage is often too small to control the excessive growth. If the effect of increasing yield is not achieved, or the dosage is too large and the regulation is too high, the plant will be too short, prone to premature aging, and the final yield increase will be small or no increase

At the same time, excessive use will cause more residues of pesticides and fertilizers in the soil, which will seriously pollute the environment and be unsafe for the next crops, and obvious pesticide and fertilizer damage will often occur

[0006] A single plant growth regulator or chemical fertilizer often has a single effect, and it is difficult to meet multiple production purposes such as regulating growth, improving quality, and increasing yield. The quality of plant growth regulating composition products has significant significance
