Plant regulation will be green and efficient

With the development of environment and ecology, there will be more and more demand for harmless biological regulators This is the information reporters learned from the 28th plant protection information exchange and pesticide machinery fair Hu Wenxiu, a researcher of the Chinese Academy of Agricultural Sciences who has devoted his whole life to the research of plant growth regulators, believes that the future development direction of plant growth regulators includes the development of new varieties, the development and application of new technologies, the development of multi-functional compound preparations, and the development of green growth regulators In the research and development of new plant growth regulators, the first is to develop to multi varieties; the second is to develop to high-efficiency regulators; the third is to put forward new requirements for the use safety of new products In addition to the requirements for plant safety, it is also required to systematically study the acute and chronic toxicity tests of new species of animals and determine the corresponding residues In the development and application of new technologies, the development and application of common plant growth regulators in new fields is also an important aspect of the development of chemical regulation technology For example, rutin is a kind of flavonoids in plants, which can promote the growth of mung bean when combined with indoleacetic acid At present, many plant growth regulators alone can not play a better role in regulation, so the development of multi-functional mixed agents is also one of the directions Plant growth regulators can also be mixed with fertilizers, microelements and other compounds to improve the regulatory function For example, the mixed use of water hyacinth extract and microelements can improve the physiological activity, growth and flowering rate of cruciferous plants On the other hand, the development of green growth regulators focuses on water-soluble, granular, slow-release, low toxicity and low pollution, minimizing organic solvents, and vigorously developing water-based emulsions, microemulsions and other sustained-release formulations with excellent performance With the development of environment and ecology, there will be more and more demand for harmless biological regulators At the forum, Aimiting, a natural plant growth regulator produced by the joint science and technology center of the National Academy of Sciences and the Ministry of science and education of Ukraine, received widespread attention Chen Minyu, the Chinese Representative Office of the joint science and technology center of the National Academy of Sciences and the Ministry of science and education of Ukraine, told reporters that the main effective ingredients of amitying are indoleacetic acid and Zeatin, which have a very significant effect on agricultural production; it can reduce the pollution of heavy metals such as mercury, cadmium, arsenic and lead; it can increase root system, promote early maturity, increase germination rate, seedling emergence rate and seedling survival rate; and enhance Stress resistance and crop quality improvement Aimiting secondary metabolites can increase soil microbial content, improve fertilizer utilization and reduce fertilizer use Since 2003, the National Agricultural Technology Extension Service Center has organized 10 provincial soil and fertilizer stations and agricultural technology stations in Henan Province to carry out experiments on wheat, corn, rice and soybean for three consecutive years The experimental results were introduced by Gao Xiangzhao and Yang Fan, who edited the book "Application of Amity on crops" The detailed data of the book attracted many dealers Yuan Yongjun, manager of hongrihong agriculture in Wuhan, said after the meeting: "I'm quite interested in aimi This product is environmentally friendly, high-yield and highly operable I don't know if I can act as an agent in Hubei."
