Effects of Nitrogen Application Rate,Planting Density and Sowing Methods on Agronomic Traits and Yield of'Bai Yan No.2'Oats
摘要
Abstract
To understand the effects of nitrogen application,planting density and sowing method on the agronomic traits and yield of'BaiYan No.2'oat,the L8(4×22)orthogonal experiment was conducted with three factors,nitrogen application rate,density,and sowing method.The application rate factor had four levels,while density and sowing method each had two levels.The results showed that the heading date of'BaiYan No.2'oats was advanced with the increase of N application rate and delayed with the increase of planting density.Plant height,number of nodes,panicle length and panicle weight all increased first and then decreased with the increase of nitrogen application rate.The results showed that the sowing mode was the main factor affecting the yield of'Bai Yan No.2'oat,followed by nitrogen application rate and planting density.The yield of combination A2B1C1 was the highest,reaching 4083.54 kg/hm2,followed by combination A1B1C1,the yield was 3880.19 kg/hm2.The yield of'Bai Yan No.2'oats was not significantly affected by different nitrogen application rates,planting densities and planting methods,but the yield of the combination of nitrogen application of 52.5 kg/hm2 and 37.5 kg/hm2,planting density of 2.85 million seedling/hm2 and strip seeding was first and second,so the best combination was A2B1C1 or A1B1C1.This study provided scientific basis for high-yield and high-quality oat planting technology of'Bai Yan No.2'.关键词
