Abstract

The invention discloses a vegetable growth regulator. The regulator contains 5-aminolevulinic acid and derivatives thereof, pimacol, compound sodium nitrophenolate, brassinolide, levulinic acid and slightly acidic electrolyzed oxidizing water, wherein the weight ratio of 5-aminolevulinic acid and the derivatives thereof to pimacol to compound sodium nitrophenolate to brassinolide to levulinic acidis 1:(2-6):(2-6):(0.01-0.1):(1-5), and the usage amount of the slightly acidic electrolyzed oxidizing water is 120-150mL relative to 1mg of 5-aminolevulinic acid and the derivatives thereof. The invention further relates to a foliage spraying method for vegetables in a sunlight greenhouse. The vegetable growth regulator is subjected to foliage spraying on the vegetables in the sunlight greenhouseunder a suboptimal temperature light condition so that the yield of the vegetables can be remarkably increased, and various pests and diseases of the vegetables are remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of promoting high-yield cultivation of plants, and in particular relates to a vegetable growth regulator and a vegetable leaf surface spraying method in a solar greenhouse. Background technique [0002] Solar greenhouses and plastic greenhouses are effective equipment for planting vegetables in winter and spring in northern my country. However, because plastic greenhouses and solar greenhouses in my country are generally relatively simple and lack necessary environmental control equipment such as temperature, light, water, and air, the facilities in winter and spring Suboptimal environments such as low temperature, low light and high humidity exist for a long time in the plant. [0003] Currently, the main research to improve plant yield is based on the synergistic effect of multiple fertilizer mixtures. For example, patent invention CN102531778A discloses a water-soluble fertilizer containing 5-aminolevulin...
