| 摘 要： | 对植物动力2003(PP2003)在玉米及甜瓜上的使用时间、剂量及使用效果进行了研究。结果表明,玉米在苗期3叶展和拔节期叶面喷施PP2003,能提高玉米单株产量,增加千粒重,较CK(喷等量清水)增产8.7%～12.1%,投入产出比为1∶3.5;甜瓜在苗期2～3叶展和开花前期叶面喷施PP2003,能提高单株产量,甜度也略有增加,较CK增产4.0%～13.1%,投入产出比为1∶5.1;t测验值均达显著或极显著水平。 |

The Experiment of Plant Power 2003 on Maize and Melon |
|
| Abstract: | The paper studied the application periods and amount of PP2003 and its efficiency on maize and melon.The results show that the yield of single plant and the 1000 grain wt.of the maize has been improved 8.7%～12.1% compared with the CK (pure water) when PP2003 was manured on the leaves during the periods of 3 leaf and elongation. The ratio of investment and yield is 1∶3.5.The yield of single plant of mellon has been improved 4.0%～13.1% compared with the CK and the sweet degree can also be improved slight when PP2003 was manured on the leaf during the periods of seedling and bloom. The ratio of investment and yield is 1∶5.1. The values of T test all reached the level of singnificance or extretme or extreme singificance. |
