Preparation and application of pollution-free corn ripening suspending agent

Abstract

The invention discloses preparation and application of a pollution-free corn ripening suspending agent. The pollution-free corn ripening suspending agent is beneficial to late corn ripening and fermentation performed after straw is returned to field, and is prepared from the following materials by weight percent: 20-30% of urea, 2-5% of biuret, 1-5% of sodium selenite, 5-10% of vegetable oil, 2-5% of thickening agent, 5-10% of emulsifying agent, 1-5% of potassium fulvate, 5-10% of corn starch and the balance of water. The pollution-free corn ripening suspending agent is an oil suspending agent processed by taking urea and biuret as active ingredients and taking vegetable oil as a synergistic ingredient; the use effect of nitrogen fertilizer is greatly improved, the permeability of the nitrogen fertilizer on blades is greatly improved, and the retention time of the effective ingredient on the blades is prolonged; furthermore, the pollution-free corn ripening suspending agent is convenient to transport and apply.

Description

technical field [0001] The invention relates to a pollution-free corn ripening suspending agent and application thereof, belonging to the technical field of agriculture. Background technique [0002] Continuous rainy weather will make mature corn moldy on the field, causing serious losses. In order to better rush to harvest and rush seeds in autumn, scientists have been exploring continuously over the years. Some use the method of drying, but the cost is high and low efficiency, and certain equipment is required, and some are converted into silage. Since there is no compound that can both increase production and accelerate ripening, the spraying time and spraying concentration of the agent will also affect the spraying effect of the ripening agent. At present, in areas where two seasons are planted in China, wheat and corn are competing for glory and heat, which is bound to have a certain negative effect on the yield and quality of corn. In view of this, it is very necess...

But it is not easy to achieve this effect

If the method is improper, it will also lead to the increase of soil pathogens, the aggravation of crop diseases and the lack of seedlings (stiff seedlings) and other undesirable phenomena
