Problems solved by technology

Methylpiperium is usually used as the original powder or a single dose or compounded with chlormequat and paclobutrazol. Its main effect is to reduce the growth and control the growth.
At the same time, the mepiperium-containing preparations currently registered at home and abroad are mainly water preparations and soluble powders, and there are the following problems: 1. The effect in increasing crop yield and improving crop quality is relatively poor, and the drug effect is unstable. The growth of crops is greatly affected, and the lodging resistance effect is poor; 2. Packaging, storage and transportation are inconvenient: the packaging cost of methylpiperium water is high, and the safety of transportation and storage is poor. Once leakage occurs, it is difficult to handle; Mix evenly and must be pulverized. The pulverized product has a large specific surface area, stronger hygroscopicity, and severe agglomeration; 3. Methylpiperium water and soluble powder can only be sprayed or flushed with water, and planted in remote areas and slopes. The application of crops in steep water-scarce areas has been greatly restricted; 4. After being applied to crops, the retention is small, the efficacy is poor, and the waste is serious

Abstract

The invention discloses a drug-fertilizer composition. The drug-fertilizer composition comprises mepiquat chloride and organic calcium. When the drug-fertilizer composition is applied to crops, the drug-fertilizer composition has remarkable effects of dwarfing plants, increasing the crop yield, and improving the lodging resistance and quality, and a composition preparation is good in water solubility, dilution stability and grain hardness and stable in quality.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a medicinal fertilizer composition, preparation and application thereof. Background technique [0002] In the current agricultural production, due to the long-term application of chemical fertilizers, the soil fertility is high, the crops grow vigorously, and the top dominance is obvious, and the vegetative growth is excessive, and it is easy to lodging, resulting in low or reduced yield. Plant growth regulators are substances used to regulate plant growth and development. For target plants, plant growth regulators are exogenous non-nutritive chemical substances, which can usually be transmitted to the site of action in plants, and can promote or inhibit certain links in their life processes at very low concentrations, making them To meet the needs of human development. Each plant growth regulator has a specific purpose, and the application technology requirements are qui...
