以焉耆垦区干旱戈壁地5年生克瑞森葡萄为研究对象,通过对高产园和低产园的叶片营养分析,进行DRIS营养诊断技术系统研究,确定了DRIS诊断的重要参数:N/P、N*K、P/K;制定了干旱戈壁地克瑞森葡萄DRIS指数诊断法的计算公式;采用“3414”配方施肥设计对焉耆垦区克瑞森葡萄进行了N、P、K三因素四水平大田试验,利用DRIS指数法对配方施肥各个处理进行检验,所诊断的N、P、K的需肥次序与实际施肥情况基本一致,但是很难达到一个相对平衡的状态。建议在生产中指导克瑞森葡萄施肥必须DRIS与其它营养诊断方法结合使用。
Taking the 5-year-old Creusun grape in the dry Gobi desert of Yanqi Reclamation as the research object, the DRIS nutrition diagnosis technology system research was conducted on the leaf nutrition analysis of the high yield and low yielding gardens to determine the important parameters of DRIS diagnosis: N / P, N * K, P / K. The formulas for calculating the DRIS index of the dry grapes in the Gobi desert were developed. The N, P, K three factors and four levels of grapes in the Yanji reclamation area were studied using “3414” In the field experiment, the DRIS index method was used to test the various treatments of formula fertilization. The order of fertilizer demand of N, P and K diagnosed was basically consistent with the actual fertilization, but it was difficult to reach a relatively balanced state. It is recommended that Crease Grape fertilization be directed in production to be used in conjunction with other nutritional diagnostic methods.
