Problems solved by technology

At present, there are many kinds of plant growth regulators used in production, among which ethephon, maize virulin, and chlormequat are mainly used to reduce plant height and prevent lodging, but at the same time, the side effects are to limit ear growth and reduce yield; three. Decyl alcohol, brassinolide, etc. can improve photosynthetic performance, but cannot effectively prevent lodging

Abstract

The invention provides a yield-increasing regulator used for expanding the ear of grains, increasing the grains and resisting the lodging for the corn, and a preparation method and an application thereof. The regulator contains the following components by certain weight percentage: a plant growth regulator, a promoting agent, a speader, absolute ethyl alcohol and water for the rest; wherein, the growth regulator is florel, gibberellin and 6-furfuryl aminopurine, the promoting agent and the speader are selected from tween 20, tween 40, tween 60, tween 80 or tween 85. The regulator has the double functions of strengthening the lodging-resistant and increasing yield, and is characterized by innocuity, no side effect, low cost, convenient usage and the like.

Description

technical field [0001] The invention relates to a regulator, in particular to a corn ear-expanding, grain-resisting, lodging-resistant and yield-increasing regulator, a preparation method and application thereof. Background technique [0002] Corn is an important food crop, the pillar of the development of animal husbandry, and its position in industrial processing is becoming more and more prominent. Corn is one of the three staple crops in my country. In 2007, the sown area of ​​corn in my country was 28.05 million hectares, the output was 148 million tons, and the consumption was 141.7 million tons, of which: edible consumption was 7.4 million tons, accounting for 5.2%; feed consumption was 93.5 million tons, accounting for 66.0%; industrial consumption was 36 million tons, Accounted for 25.4%. The direct result of the rapid development of corn industrial processing is that the demand for corn has increased significantly. It is estimated that by 2010, the actual consumpt...
