种子与硼肥同播对直播油菜生长及产量的影响
Effect of Co-sowing of Seeds and Boron Fertilizer on Growth and Yield of Direct Seeding Rapeseed
摘要
Abstract
The experiments of co-sowing of rapeseed seeds and boron fertilizer were conducted at three different experimental locations in Hengyang area to study the effects of different boron fertilizer application rates(0,4.5,9.0,13.5 kg/hm2)on the growth and yield of rapeseed.The results showed that applying an appropriate amount of boron fertilizer was beneficial to promoting the emergence and seedling formation of direct seeding rapeseed.The treatment with the boron application rate of 13.5 kg/hm2 on the 31st day after sowing had the highest number of seedlings,while the treatment with the boron application rate of 9.0 kg/hm2 before harvest had the highest number of effective plants.After applying boron fertilizer,the primary branch number,pod number per plant,and grain number per pod of rapeseed showed a trend of first increasing and then decreasing with the increase of boron fertilizer application rate.The rapeseed yield was the highest at the boron application rate of 9.0 kg/hm2.The recommended boron fertilizer rate in production is 9.0 kg/hm2,but when the soil boron is extremely deficient,the recommended boron fertilizer rate may be 13.5 kg/hm2.关键词
