欧美宝金银素在水稻上的应用效果试验

The Application Effect of OuMeiBao Foliar Fertilizer on Rice

目的:选用2种欧美宝金银素(粉剂、液剂)进行田间试验,筛选出适合盐城地区施用的、效果好的叶面肥。方法:分别在水稻的破口期和齐穗期喷施欧美宝金银素,粉剂每hm2用1.2kg、兑水450kg;液剂每hm2用1.5L、兑水450kg,后期对穗粒结构及产量进行比较分析。结果:喷施欧美宝金银素液剂对株高和穗长均有促进作用,并且能够增加穗粒数和千粒重,实际产量与对照相比显著增加;欧美宝金银素粉剂的增产效果不显著。结论:喷施欧美宝金银素液剂能够增加产量,该试验结果可以为欧美宝金银素液剂的推广提供依据。

[Objective]Two kinds of Ou Mei Bao foliar fertilizers（powder and liquid）were used for field experiment,and then screened out the good effect foliar fertilizer which was suitable for the region.[Method]Spraying Ou Mei Bao foliar fertilizer in the period of rice break and full heading date.The powder is applied in 1.2 kilogram per Ha with450 kilogram water;The liquid is applied in 1.5 liter per Ha with 450 kilogram water,the grain structure and yield were compared at last.[Results]Spraying Ou Mei Bao foliar fertilizer liquid promoted plant height and panicle length,and it also increased the number of grains per spike and 1000 grain weight,The actual yield was significantly higher than the control.The effect of Ou Mei Bao foliar fertilizer powder was not significant.[Conclusion]Spraying Ou Mei Bao foliar fertilizer liquid can increase yield,and the results of this experiment can provide the basis for the promotion of Ou Mei Bao foliar fertilizer liquid.
