Preliminary study on synergistic effect of Kelpak(R) organic water soluble fertilizer and Plant-soul(R) foliar fertilizer on rice yield increase
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.
