example 1

[0016] The formula of corn control compound growth regulator: Brassinolide 60mg (dissolve the solid in absolute ethanol first, then dissolve in water), amine fresh fat 450mg, ethephon 18g, KH 2 PO 4 60g, Tween 20 0.39ml, distilled water to 1000mL; this is the amount for one mu of land, mix according to the above ratio, stir at room temperature for 3 hours, that is, the compound growth regulator for corn height control.

example 2

[0018] Taking the corn variety Xianyu 335 popularized in the market as the experimental material, the spraying test of the growth regulator was carried out in the bell mouth stage of the corn, and the commercially available mepipebine and water were used as the control. One month later, each plot randomly measured the plant height of 10 maize plants, and the data in Table 1 are the average value of 10 data for each treatment. The test results showed that spraying the compound growth regulator for corn height control could significantly inhibit the plant height of corn, shorten the length of corn internodes, and achieved a good purpose of height control. The specific method is: divide the area of ​​each community into 30m 2 , Dilute the growth regulator upside down to 30L and mix evenly, take out 1.5L from it, and spray 1.5L of the solution on each plot. Metered amine was implemented according to the amount used by farmers, and water was used as a control. It was used around ...

Abstract

The invention discloses a height-controlling composite growth regulating agent for corn and a preparation method thereof, and a method for applying the height-controlling composite growth regulating agent to corn, belonging to the field of agricultural production. The preparation method comprises the following steps: separately dissolving brassinolide, diethylaminoethyl hexanoate, ethephon and KH2PO4, then uniformly mixing the above dissolved substances under stirring so as to obtain a mixed solution, adding Tween 20 and carrying out dilution with water so as to obtain the height-controlling composite growth regulating agent for corn. The height-controlling composite growth regulating agent can obviously reduce the height of corn, improve the thickness of stalk, promote the development of aerial roots and lateral roots and increase the content of chlorophyll in corn leaves, achieves the purposes of height control, resistance to lodging and yield increase, and has the advantages of safety, environmental protection, no harm to crops, etc. Moreover, the preparation method is simple and suitable for large-scale production.

Description

technical field [0001] The invention discloses a compound growth regulator for corn height control, a preparation method thereof and an application method on corn, belonging to the field of agricultural production. Background technique [0002] The main contradiction in corn planting is lodging caused by too high plants. The plant heights of high-yielding corn varieties currently on the market are all on the high side, causing the contradiction between high-yield and lodging to become more and more prominent, which seriously affects the increase of corn yield. Therefore, the chemical regulation of the whole growth period of maize is an important means to control the plant height and improve the yield and quality of maize. Brassinolide (BR) is one of the six internationally recognized phytohormones, with the highest activity, broadest spectrum and non-toxicity. Studies have found that BR has the functions of regulating plant height, improving plant shape, promoting root grow...
