Abstract:

The effect of liquid-coated urea to be sprayed onto apple leaves were studied and water only (CK) on apple trees growth were compared in open field experiment.The results showed that the effect of liquid-coated urea on apple trees growth was more significant than that water only,the number of new tips increased by 50%，leaf thickness increased by 15%，fresh weight of leaf increased by 6.2%，leaf area increased by 9.3%，100-kernel weight increased by 4.4%，fruit type index increased by 3.3%，the apple yield increased by 9.8%.Apple yield and economic benefits increased remarkably.
