- 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 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.
