Plant growth regulating composition containing brassin and S abscisic acid

Abstract

The invention discloses a plant growth regulating composition containing brassin and S abscisic acid, wherein the plant growth regulating composition comprises 0.0001-0.1% of brassin, 0.01-3% of S abscisic acid, a surfactant, 20-50 g of urea, 10-30 g of a trace element fertilizer, 20-50 g of water-soluble polyvinyl butyral and 100 g of water. According to the invention, various plant growth regulating components are loaded and combined through a high polymer material, brassin with high activity and S abscisic acid synergistically induce and regulate the anti-freezing performance of plants, anda proper amount of amino acids and trace elements are matched to intervene in the growth of the plants in the anti-freezing induction process, so that the plants have good environmental adaptabilityin different growth stages, and the later growth of the plants is effectively promoted while the freezing resistance of the plants is rapidly improved.

Description

technical field [0001] The invention belongs to the technical field of garden plant protection, and in particular relates to a plant growth regulating composition containing brassinolide and S-induced resistin. Background technique [0002] In the process of urban construction, a large number of plants need to be planted for greening, but many plants have certain requirements for the growth environment temperature, especially in northern China, when the atmospheric temperature drops below zero degrees Celsius, many plants are frozen to death because they cannot withstand the severe cold. [0003] The use of antifreeze can significantly improve the frost and cold resistance of plants. The main components of existing plant antifreeze generally include seaweed extracts: strong antifreeze ability, rich in active organic matter, sugars, alcohols, and natural growth regulators , anti-stress factors, etc., can increase photosynthesis, enhance nutritional levels, and improve frost r...

Problems solved by technology

Although it can improve the frost resistance of plants, most plant antifreezes are not suitable for plants in northern regions, and it takes a process to take effect, but this process usually takes a certain amount of time. The adjustment of plant frost resistance is slow, and hormones Although plant-like antifreezes work quickly, simple hormone stimulation will affect the subsequent normal growth of plants
