摘要
以章古台沙地栽培的4年生平欧杂种榛“达维”品种为研究对象,采用响应面分析法(RSA)设计施肥试验,以尿素、磷酸二铵、硫酸钾三因素非自由搭配设计小区,计算达维最高产量的施肥组合,并计算最佳施肥时的产量潜能。结果表明:4年生达维最高榛子产量可达418.063 g·株^-1,若在该地区达到最高株产量,施肥量应为尿素150.00 g·株^-1,磷酸二铵156.77 g·株^-1,硫酸钾220.59 g·株^-1。
Response surface analysis(RSA)was used to design the fertilization experiment.Urea,diammonium phosphate and potassium sulfate were used as three factors of non self matching plot to calculate the highest yield fertilization matching and the yield potential of the best fertilization.Result shows that the highest yield of 4-year-old Corylus heterophylla×C.avellana is 418.063 g·plant^-1.If it reach the highest yield in this area,the fertilization amount should be 150.00 g·plant^-1 urea,156.77 g·plant^-1 diammonium shosphate&220.59 g·plant^-1 potassium sulfate.
