Abstract

The invention provides a compound conditioning agent for delaying senility of leaves of wheat and/or improving yield, an application of same and a medicament comprising same, wherein 1 kg of the compound conditioning agent includes: 20-40 mg of sodium nitroprusside, 200-400 mg of salicylic acid, 22000-50000 mg of monopotassium phosphate, and the balanced being water. The compound conditioning agent can delay the senility of leaves of wheat and/or improve the yield of wheat, and has excellent technical effects.

Description

technical field [0001] The invention relates to a composite regulator for delaying wheat leaf senescence and / or increasing wheat yield, and belongs to the field of plant regulators. Background technique [0002] The Huang-Huai-Hai area is the most important wheat production area in my country. The growth and development of wheat in this area has the characteristics of long tillering period, long panicle differentiation period and short grain filling period ("two long and one short"), so the tillering of wheat in this area can basically meet the requirements. The number of spikes is required, and the advantages of multiple flowers and multiple grains are obvious, which is conducive to the formation of large spikes and multiple grains. However, due to unfavorable weather, especially high temperature and drought, leaf chlorophyllase and membrane lipid peroxidation often occur in the late stage of grain filling in the Huanghuaihai region. Changes in the activities of superoxide di...
