Seed treatment agent suitable for flooding resistance of hemarthria and application

Abstract

The invention discloses a seed treatment agent suitable for flooding resistance of hemarthria and application. The seed treatment agent is prepared from the following components: 150-180 mg / L calcium chloride, 100-150 mg / L boric acid, 10-30 mg / L silica gel, 20-30 mg / L polyvinyl alcohol and 1-5 mg / L naphthylacetic acid. The seed treatment agent disclosed by the invention can be used for effectively improving the flooding resistance of hemarthria seeds, can be used for improving the germination rate of the seeds and promoting elongation of roots if being used, and has relatively huge promotional value.

Description

technical field [0001] The invention belongs to the field of plant seed treatment, and in particular relates to a seed treatment agent suitable for waterlogging of verbena and its application. Background technique [0002] Verbena, Verbena ( Hemarthria ), perennial gramineous plants, with many species, mainly rely on rhizome radiation to reproduce; in different habitats, the plant type difference is obvious; open habitat species, mostly born in riverside wetlands, swamps, seasonal river flooded grasslands, rice fields or Humid farmland ridges, ditches, river beaches and other wet places; often do not form dominant species, most of them are associated or scattered species. In the middle and upper reaches of the Yangtze River, wild bullwort is often associated with bermudagrass, false thrift ( Eremochloaop hiuroides ), paspalum ( P. distichum ) and other warm-season grass species; it is widely distributed from 39 m to 2215 m above sea level, and can be found in Northeast, ...

AI Technical Summary

Problems solved by technology

Under the condition of complete submersion, the oxygen supply of plants is reduced, anaerobic respiration is intensified, the utilization efficiency of carbohydrates is significantly reduced, and the consumption of carbohydrates in the body is aggravated (Gibbs & Greenway, 2003), which is not conducive to plant growth and survival

Especially when the planted bullwhip seeds encounter heavy rain and flooding before they germinate, the germination rate and rooting rate of the verbena seeds will be limited when the verbena seeds are completely flooded. Water resistance of grass seeds is of great significance
