Growth regulator special for leaf vegetables

Abstract

The invention provides a growth regulator special for leaf vegetables and belongs to the field of chemical control of plants. The growth regulator comprises the following components in percentage by weight: 10 to 30 percent of plant growth regulator, 0.3 to 10 percent of emulsifying agent, 2 to 10 percent of stabilizing agent, a proper amount of pH value regulator which controls a pH value of thesystem to be 2 to 3 and the balance of water, wherein the plant growth regulator comprises gibberellin and ethephon in a weight ratio of 1:35-100. By being diluted by 1,500 to 2,000 folds and then sprayed on the leaf vegetables planted in fields, the special regulator of the invention can improve activity of root systems of plants, improve functions of leaves, deepen color of leaves, enlarge areas of leaves, regulate growth of plants, brighten stems and make stems uniform and strong; and for vegetables capable of being harvested for multiple times, such as water spinach and the like, the growth regulator special for leaf vegetables can improve the quality of the vegetables, increase yield and shorten a harvesting cycle by being sprayed on the vegetables during the whole period after filedplanting.

Description

technical field [0001] The invention belongs to the field of phytochemical control, and in particular relates to a plant growth regulator specially used for leafy vegetables. Background technique [0002] Water spinach, celery, cabbage, lettuce and other leaf vegetables are important varieties on people's tables, and their nutritional value cannot be replaced by tuber and solanaceous vegetables. At present, there are many kinds of growth regulators used in the production of leafy vegetables. Among them, amine fresh fat, triacontanol, gibberellin, etc. can improve photosynthetic performance, but have little effect on the thickening of stem tips, and leaf growth often occurs during use. Large and thin stems; ethephon, chlormequat, mepiquat, etc. can make the stems thick, but at the same time shorten the length of the plant internodes and affect the product quality. It can be seen that there is a certain degree of defect in using any of the above-mentioned growth regulators al...

Problems solved by technology

Although some patent applications for the joint application of gibberellin and ethephon have been disclosed in the Chinese patent library, most of them are designed for food crops such as wheat and corn. Used on corn to achieve the effects of dwarfing plants, shortening internode length and lodging resistance, but if this product is used on leafy vegetables, it is very easy to produce side effects such as dead leaves, fallen leaves, restricted growth, and reduced yield.
