Rooting-promoting, disease-resistant and plant-strengthening agent for cotton and water, fertilizer and pesticide integrated application method

Abstract

The invention discloses a rooting-promoting, disease-resistant and plant-strengthening agent for cotton and a water, fertilizer and pesticide integrated application method. The rooting-promoting, disease-resistant and plant-strengthening agent is mainly prepared from a growth regulator, a microelement, a signal molecule donor and an elicitor capable of improving the disease resistance of the cotton, wherein the growth regulator is prepared from indolebutyric acid, sodium nitrophenolate, naphthylacetic acid and diethyl aminoethyl hexanoate through compounding, the microelement is prepared from zinc sulfate, ferrous sulfate, ammonium molybdate, amino acid powder and ammonium hydrogen phosphate through compounding, the signal molecule donor is NO donor sodium nitroprusside, and the elicitor is a penicillium dry mycelium extracting solution. The problems that a drip irrigation technology does no good to root development and severe diseases are caused by successive cropping to the cotton are solved, the growth regulator accelerates growth of root systems, the physiological function time of the root systems is prolonged, the disease-resistant elicitor enhances the resistance of cotton plants, growth of lateral roots is further promoted in combination of the signal molecule donor, and the disease-resistant response of the cotton plant is promoted. The rooting-promoting, disease-resistant and plant-strengthening agent can promote growth of roots and resist diseases in multiple angles; the agent can be injected into irrigation water through a fertilizer pump, integrated application of water, fertilizer and pesticides in the drip irrigation cotton field of the northwest inland is realized, and the agent can promote growth of roots, resist diseases and strengthen seedlings and has remarkable disease resisting and yield increasing effects.

Description

technical field [0001] The invention relates to the field of crop growth regulators, and relates to a cotton root-promoting, disease-resistant, and plant-strengthening agent and an integrated application method of water, fertilizer, and medicine. Background technique [0002] The inland area of ​​Northwest my country is the main area of ​​cotton production in China. This area is a typical arid irrigated agricultural area with extremely limited fresh water resources. Cotton drip irrigation technology can save fertilizer, water, and labor, and can promote the synchronization of water and fertilizer. It only needs automatic control or valve manual, which greatly improves work efficiency. Drip irrigation technology is an inevitable trend in the development of cotton industry in this area. . However, drip irrigation is not conducive to the downward pricking of the cotton root system. The cotton root cap becomes smaller and the root system moves upward. It is mainly distributed i...

Problems solved by technology

At present, disease prevention and control generally involves spraying carbendazim or thiophanate-methyl 2 to 3 times at the seedling stage. The above-mentioned method is not only labor-intensive, but also although the pesticides currently used are all low-toxic preparations, a large amount of exposure will still cause harm to the human body. Adverse reactions

[0004] Therefore, aiming at the problem that drip irrigation technology is not conducive to root system development and the problem that heavy cropping causes serious cotton diseases, the present invention provides a kind of cotton root-promoting, disease-resistant and strong plant agent suitable for irrigation with water in combination with drip irrigation. of cotton production is of great significance
