快宝~有机水溶肥与喷得福~系列叶面肥协同促进水稻增产效果初步研究

Preliminary study on synergistic effect of Kelpak~ organic water soluble fertilizer and Plant-soul~ foliar fertilizer on rice yield increase

研究了在水稻生长发育期喷施生物产品快宝~有机水溶肥与喷得福~系列叶面肥(新肥处理),对水稻种子生根发芽、生长发育的影响及促进水稻增产的效果。结果表明,在水稻秧苗期、分蘖期、拔节孕穗期和结实期叶面喷施该产品可以显著提高水稻处理秧苗的茎基宽度、新生根长度和鲜重,分别比当地施肥对照秧苗增加8.00%、48.53%和20.00%;水稻分蘖期处理的每穴株数、地上部鲜重及干重、伤流液量分别比对照增加11.62%、14.66%、17.20%和58.23%。在21d积累期内,处理的水稻植株干物质比对照增加60.63%;处理植株的净同化率比对照增加26.15%;处理的水稻平均每穴有效穗数比对照增加24.33%。处理的水稻实收产量9 315.15kg/hm^2,比对照增产6.63%。

The effects of applying Kelpak（R） organic water-soluble fertilizer and Plant-soul（R） foliar fertilizer （new fertilizer treatment）on seed germination,growth,development and grain yield were investigated in rice（Oryza sativa）.The results showed that foliar application of the new fertilizers at stages of seedling,tillering,jointing and booting and seed setting could significantly increase the width of stem,length and fresh weight of the new roots by 8.00%,48.53% and 20.00%,respectively,compared with the control of local fertilizer application.The number of plants per hole,the fresh weight and the dry weight of the plants above the ground,and the root bleeding at mid-tillering stage were obviously higher under application of new fertilizers than those under control by 11.62%,14.66%,17.20% and 58.23%,respectively.During a 21-day accumulation period observed,the dry matter,the net assimilation rate and productive panicles per hole of rice plants treated by the new fertilizers increased by 60.63%,26.15% and 24.33% respectively in comparison with the control.The grain yield of the new fertilizer treatment was 9 315.15 kg/hm2 and 6.63% higher than the control.
