Problems solved by technology

At present, chlormequat is promoted in the market to adjust the height of corn plants. Triadimefon fungicides have their own advantages in preventing and controlling leaf spot, smut, and rust. A single dose of oxazolone needs 2 to 3 times, and it needs to be sprayed 4 to 5 times in a short period of 10 to 15 leaves. The number of sprays is large, the cost is high, the labor intensity is high, and the increase in plant height brings inconvenience to spraying, which brings great harm to the environment. Agricultural production enterprises, growers and professional prevention and control teams have brought many difficulties

preparation example Construction

[0029] The invention provides a preparation method of the corn synergist described in the above scheme, comprising the following steps: mixing chlormequat, triadimefon, carrier and dispersant, pulverizing after stirring, and mixing the pulverized material with water After grinding, the synergist is obtained.

[0030] In the invention, chlormequat, triadimefon, carrier and dispersant are mixed to obtain a mixture. The mixing equipment of the present invention is preferably a mixing drum of a powder mixer. Stirring is preferred during the mixing in the present invention, and the stirring speed in the present invention is preferably 80-120 r / min, more preferably 90-110 r / min, most preferably 100 r / min. The stirring time in the present invention is preferably 4-6 minutes, more preferably 5 minutes.

[0031] After the mixed material is obtained, the present invention stirs and pulverizes the mixed material to obtain the pulverized material. The crushing equipment of the present ...

Abstract

The invention provides a corn synergist and preparation and application methods thereof and belongs to the technical field of crop conditioners. The corn synergist is made from, by weight part, 50-70parts of water, 15-25 parts of chlormequat chloride, 8-12 parts of triazolone, 3-6 parts of a carrier and 3-7 parts of a dispersant. The corn synergist can significantly reduce the plant height as well as ear height of corn plants and thicken the stems of crops, and meanwhile evidently prevent and treat leaf blight, rust, smut and sheath blight, thereby significantly increasing the yield of corn.

Description

technical field [0001] The invention belongs to the technical field of crop conditioning agents, and in particular relates to a corn synergist and its preparation method and application. Background technique [0002] Maize lodging is an important hazard in maize production and has always been an important factor affecting maize yield and quality. According to statistics, maize lodging causes yield reduction of 20% to 50%, and the yield loss of maize due to lodging is nearly 1,000,000 tons every year. The reason is that natural factors wind and rain are the direct causes of lodging, fertilizer and water management is an important factor, and pests and diseases are inducing factors. At present, with the continuous improvement of the cultivation level of corn, the contradiction between high density, super high yield and corn lodging has become increasingly prominent, coupled with the impact of disastrous weather in recent years, corn leaf spot, sheath blight, smut, rust, etc. ...
