摘要
以‘云粳37’水稻品种为试验材料,设置5个不同缓释肥与尿素混施处理及1个对照处理,比较不同处理水稻产量、品质和种植经济效益。结果表明,缓释肥与尿素混施有助于增加水稻产量,提高水稻整精米率,降低垩白粒率及垩白度,增加水稻种植经济效益。综合考虑,认为缓释肥与普通尿素施入比例为5∶5~6∶4,水稻种植效果最佳,是最适宜云南昭通的水稻种植施肥模式。
In this paper,the'Yunjing 37'rice variety was used as the experimental material,five different treatments of mixed slow-release fertilizer,urea and one control treatment were set up.The rice yield,quality and planting economic benefits of different treatments were compared.The results showed that the mixed application of slow-release fertilizer and urea was beneficial to increase rice yield,improve whole rice milling rate,reduce chalky grain rate and chalkiness degree,and increase the economic benefits of rice planting.Considering comprehensively,it's concluded that the application ratio of slow-release fertilizer to common urea between the 5:5 to 6:4,and the rice planting effect is the best,which can be considered the most suitable rice planting mode in Zhaotong,Yunnan.
