Problems solved by technology

These technical schemes have obvious defects, diethyl hexanoate is not stable enough in ethephon, and during use, the use effect of the medicament is greatly affected by climatic conditions; auxin and gibberellic acid are plant growth promoters, which make the internodes of maize Elongation, the leaves become longer and narrower, which is opposite to the goal of ethephon in regulating the growth of corn, and it is an antagonistic effect; although cytokinin can increase the leaf area above the ear of corn, it will cause the leaves to droop, resulting in the use of light by the leaves In the case that the functional leaves have not yet grown, a small amount of supplementation of plant nutrients, fulvic acid, humic acid, etc. on the leaf surface has little effect on improving the development of the upper leaves of the panicle and the ability to accumulate assimilates

Embodiment 1

[0034] 1. Test object: corn

[0035]2. Test method: with reference to GB-T17980.139-2004_Pesticide Field Efficacy Test Guidelines (2) Part 139: Maize Growth Regulator Test, test according to the stated requirements. When the corn plant grows to 6-12 leaves, a single drug and a composition are respectively used to prepare a spray solution with a required concentration, and the spray liquid is evenly sprayed on the upper leaves of the corn plant.

[0036] 3. Statistical analysis of data: DPS7.05 (Duncan) statistical software was used for analysis. The average stalk diameter D1 of corn was calculated according to the test data, and the average stalk diameter growth rate T1 (%) relative to the blank control was calculated at the same time. The results are shown in Table 1.

Abstract

The invention discloses a plant growth regulating composition, preparation and application thereof for corn. The composition is composed of ethephon and cyclopropanamic acid at a mass ratio of 1-30:1. The composition or its formed The preparation is sprayed on corn plants to make the corn stalks thicker, increase the leaf area above the ear position, weaken the leaf tropism, improve the photosynthetic efficiency of the leaves, improve the lodging resistance and the uniformity of the population, and increase the yield of corn per mu. When using a single drug, the effect is obviously improved, and has a significant synergistic effect.

Description

technical field [0001] The invention relates to the field of plant growth regulators, in particular to a plant growth regulator composition, preparation and application for corn. Background technique [0002] Corn is a monocotyledonous plant, which is an annual grass plant, also known as corn, corn, six valleys, etc. In the planting practice of corn, the stalks tend to grow too fast, thin, fragile, easy to lodging, and the group uniformity is poor, thus affecting the yield of corn. Especially in areas where high winds and rainstorms occur frequently, the lodging of corn before it matures is an important reason for severe production reduction. [0003] Ethylene is one of the five major endogenous hormones of plants. It participates in various life activities of plants and can be produced in many parts such as roots, stems, leaves, flowers, fruits and seeds. Its physiological function is to stimulate cell membrane permeability and promote RNA Synthesis, a regulatory switch o...
