水稻田间小区试验结果表明，在施纯氮１７．１ ｋｇ／６６７ｍ ２ 的基础上，于分蘖期和孕穗期喷施“植物动力２００３”（以下简称“２００３”）的两个处理稻谷实产与对照（施纯氮１９．０ ｋｇ／６６７ｍ ２ 加喷清水）的实产相比，无明显差异；同样，在施纯氮１７．１ ｋｇ／６６７ｍ ２ 处理中，无论是分蘖期或是孕穗期喷施“２００３”，其植株倒三叶叶片的叶绿素含量均高于对照。盆栽水稻１５Ｎ 示踪试验结果表明，在等氮条件下，土壤肥力水平较高的青紫泥，分蘖期喷“２００３”和孕穗期喷“２００３”两个处理，平均每盆水稻的籽粒产量和氮肥利用率分别比对照增加４．９３％ 、９．４１％ 和１．９１％ 、３．２２％ ；土壤肥力水平中等偏低的夹沙泥，分蘖期喷和孕穗期喷“２００３”两个处理，平均每盆水稻的籽粒产量和氮肥利用率分别比对照增３．３２％ 、７．３８％ 和１．６８％ 、３．５２％ 。
The results of field trials in paddy fields showed that the two treatments of rice plantation 2003 at the tillering and booting stages were conducted on the basis of 17.1 kg / 667 m 2 of applied nitrogen There was no significant difference between the control and the control (applying pure nitrogen 19.0 kg / 667m 2 plus spraying water). Similarly, in the treatment with pure nitrogen at 17.1 kg / 667m 2, no matter at the tillering stage or the booting stage Spraying “2003”, the plant clover leaf chlorophyll content were higher than the control. The results of 15N tracing experiment on potted rice showed that under the condition of isophoric nitrogen, purple clay with higher soil fertility, “2003” at the tillering stage and “2003” at the booting stage were treated with the average grain yield and nitrogen fertilizer The utilization rates of the two treatments increased by 4.93%, 9.41% and 1.91%, 3.22% respectively than those of the control. The soil fertility was moderately lower than that of the control, with “2003” at the tillering and booting stages The average grain yield and nitrogen use efficiency per pot of rice increased by 3.32%, 7.38% and 1.68%, 3.52% respectively compared with the control.
