| 摘 要： | 针对河南省气候土壤特点,对锌肥在苏丹草(Sorghumsudanense(Piper))生产中的应用进行了研究。结果表明:苏丹草锌肥的有效范围为400～1000mg/kg,最佳利用浓度为800mg/kg。在最佳利用范围内,LAI提高了9.09%,种子产量提高13.0%。在400～600mg/kg情况下,苏丹草茎秆分别增粗4.19%～7.09%,牧草产量分别提高5.1%～5.4%。

| Abstract: | Based on soil conditions in Henan province, this paper made many applied studies about the application of Zn fertilizers in Sudangrass[Sorghum sudanens(Piper)] production,and analyzed applied ranges and concrete measures. The results showed Zn effective applied concentration range is from 400mg/kg to 1000 mg/kg and optimum concentration is 800mg/kg which can enhance LAI by 9.09% and forage yield by 13.0%. Under the concentration range (400~600mg/kg), diameter of stalk and forage yield can be raised by 4.19%~7.09% and 5.1%~5.4% respectively. |
