Abstract
The invention discloses a water-retaining agent initiating method for improving crop seed vigor. The water-retaining agent initiating method comprises the following steps: mixing a water-retaining agent and a plantgrowth regulator solution according to the ratio of 1 g / L to 10 g / L, and carrying out sufficient and uniform stirring to prepare an initiating matrix so that the water-retaining agent sufficiently absorbs water, wherein the concentration of an diethyl aminoethyl hexanoate solution is 0.1 mmol / L to 0.6 mmol / L. Under a proper initiating condition, the crop seed vigor can be remarkably and cooperatively improved, and the germination rate and the field emergence rate are improved. The water-retaining agent initiating method disclosed by the invention is simple in preparation process and convenient to operate; product and environment pollution is not caused and phytotoxicity is not easy to generate; and the water-retaining agent initiating method has a wide application prospect.
Description
technical field [0001] The invention relates to the technical field of agricultural chemistry, in particular to a method for initiating a water-retaining agent for improving the vigor of crop seeds. Background technique [0002] Seeds are important means of agricultural production, and improving seed quality is an important guarantee for efficient, stable and high-quality agricultural production. Seed vigor is an important indicator of seed quality, which determines whether the seeds can emerge quickly and neatly in the field and grow into normal seedlings. High-vigorous seeds have obvious growth advantages and production potential, and are of great significance for improving seed storability and field seedling rate, resisting seedling adversity (low temperature, drought, pests and diseases, etc.), saving sowing costs, and increasing crop yield. In agricultural production, it is very important to carry out research on methods to improve the germination rate and field emerge...
