Roadside Vegetation Establishment by Seeding of Herbaceous Species Under Suboptimal Conditions

摘要

In seeding trials, fall seedings performed better than spring seedings. Legume establishment was best in the spring, as long as adequate weed control measures were used. The soil temperature of north and south facing slopes was strongly influenced by mulching. Straw mulching reduced surface temperatures by an average of 5C. Alternating temperatures caused a stunting of growth compared to radicle growth under constant temperatures. Polyethylene glycol induced moisture stress also caused a decrease in the amount of radicle growth.
