- 摘要:
- 以“香玲”核桃品种为试验材料，采用“3414”最优回归设计的方法，研究了配方施肥对核桃果实营养和性状的影响，以期促进香玲核桃的高产和高优。结果表明：磷肥是影响核种仁发育的关键因素，并且氮、磷、钾对核桃平均单果质量的影响较为微弱。各施肥处理与对照相比，N、P2O5、K2O的不同配比对核桃果实和叶片的部分指标有很大的影响，综合考虑营养配比在提高坚果三径大小、核仁营养和叶片中氮磷钾的含量的关系，认为单株施纯N、P2O2、K2O分别为0.990 2、0.660 1、0.990 2 kg的施肥方案有助于核桃果实品质的提高。
- Abstract:
- ‘Xiangling’precocious walnut was used as experiment material to study the effect of characteristics and yield of walnut according to the theory of “3414” regression optimum design,in order to obtain high yield and high quality walnut of ‘Xiangling’.The results showed that P was key factor affecting the development of kernels,and N,P and K had a slight effect on the average weight of walnuts.The different proportions of N,P2O5 and K2O had a great impact on the indexes of walnut by comparing with CK.Taking into account the ratio of fertilizer to improve the size of the three diameters of nuts,the nutrition of kernels and the content of N,P and K in the leaves,that treatment 10 (applying N,P2O5,K2O each plant for 0.990 2、0.660 1、0.990 2 kg) had the best fertilization effect.
