| 摘 要： | 研究了控释BB肥在木薯上的应用效果。结果表明,随着控释BB肥用量的增加,木薯株高、茎基部粗度显著增加,施氮量20kg处理的木薯产量分别较施氮量10、15kg处理增加33.8%和32.7%。随着施肥次数的增加,木薯株高、茎基部粗度有增加趋势,在低施肥量下随着施肥次数的增加,结薯数和产量也有增加趋势,但高施肥量下以一次施肥或二次施肥产量较高,三次施肥明显降低。因此,木薯应用控释BB肥时应适当增加肥料用量以获得显著增产效果,同时,施肥方法采用一次施肥或二次施肥均可。

| Abstract: | Field trials were conducted to study the effects of control-released BB fertilizers on cassava production. Results showed that plant height, diameter of stem base were significantly increased as the increase of fertilization rates. Rate at 20 kg N per 667m2 resulted in greater tube number/pant and tube weight/plant, with the average yield was 32.7% and 33.8% higher than treatments of 15 kg and 10 kg per 667 m2. In conditions of low fertilizer rates, there was a trend that plant height and diameter of stem b... |
