Abstract:
Hot pepper varieties‘Rui Te Er Hao’was taken as test materials,adding different proportions of Protaetia brevitarsis (Lewis) larvae dung(referred to as worm dung,2%,5%,10%,20%) in the nursery substrates,to investigate the effects on development under the condition of low temperature hot pepper seedlings.It was expected to reveal the mechanism of insect feces promoting plant development at low temperature.The results showed that the volume was added in the nursery substrates were 2% and 5% for the two treatment conditions,chili seedling biomass,root growth and seedling index were significantly higher than those of control,in which the whole plant dry weight was higher of 32.3%,29.3% than in control respectively,strong seedling index were higher of 15.4% and 33.4%,in terms of root development,worm dung added 2%,chili seedling root volume was the biggest,30.4% higher than control,worm dung added 5%,root dry weight and root activity were the highest,were higher of 31.9% and 57.4% than those of control.The results showed that appropriate proportion of worm dung could improve the cold tolerance of pepper seedling.
