Abstract:
A field fertilization experiment with randomized block design were conducted,the effects of different treatments of N,P,K on the yield,quality and economic benefits of Zizyphus jujube ‘Qiyuexian’ was studied.The results showed that the different NPK fertilization proportion could effectively improve the yield and economic benefits of the jujube.Of all the treatments,the ratio of urea∶superphosphate∶K2SO4 at 0.5∶1∶0.4 (N∶P2O5∶K2O=1.92∶1∶1.67) was the best,which could increase the field by 50 percent and increase economic benefits by about 70 000 yuan per hectare.On the impact of quality,the proportion of urea∶superphosphate∶K2SO4 at 0.5∶0.5∶0.4 was the best.Appropriate NPK fertilization proportion could increase the field,improve the quality and reduce the excessive application of fertilizers.
