Study on Seed Germination, Growth and Nutrient Release of Kentucky Bluegrass in Pressed Granulated Grassland
Main Article Content
Abstract
The effects of pelleted pelleting on seed germination, growth and nutrient release of Kentucky bluegrass were investigated. By comparing the seed germination rate, germination potential and seedling growth index of different pelleting, combined with the analysis of nutrient release in soil environment, the synergistic mechanism of pelleting and nutrient release was revealed. The results showed that F1 ( 80 % bentonite : 10 % organic fertilizer : 10 % sheep manure ), F2 ( 70 % bentonite : 15 % organic fertilizer : 15 % sheep manure ), F3 ( 60 % bentonite : 20 % organic fertilizer : 20 % sheep manure ), F4 ( 50 % bentonite : 25 % organic fertilizer : 25 % sheep manure ), F3 treatment can significantly improve seed germination time and growth height, and delay nutrient release rate. This study provides a theoretical basis for optimizing the pelleting process, and has practical significance for achieving precise quantitative seeding and reducing application efficiency.
