| 摘 要： | 为了验证尿素涂膜液在苹果上的喷施效果,在大田试验条件下,采用叶面喷施尿素涂膜液和清水(CK)的方法研究了苹果叶面喷施尿素涂膜液的增产效果。结果表明:苹果叶面喷施尿素涂膜液新梢生长量、叶片厚度、叶片鲜重、叶面积分别比对照增加50.0%、15.0%、6.2%和9.3%,百果重、果型指数分别比对照提高4.4%和3.3%,产量较对照增产9.8%,增产效果明显。 |

| 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 by15%,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. |
