Effect of Chemical Fertilizer Cooperated by Bio-organic Fertilizer on Growth,Development and Yield of Hemp
In order to determine the effect of combined application of bio-organic fertilizer on the growth and yield of hemp for flowers and leaves,the effect of combined application of bio-organic fertilizer on growth index,dry matter weight,photosynthetic related index and yield of hemp for flowers and leaves were studied with"Hemp No.7"as experimental material.The results showed that plant height,stem diameter,branch number,leaf area,dry matter weight,photosynthetic rate(Pn),stomatal conductance(Gs),intercellular carbon dioxide concentration(Ci)and transpiration rate(Tr)in F1(90% fertilizer+10% bio-organic fertilizer),F2(80% fertilizer+20% bio-organic fertilizer)and(70% fertilizer+30% bio-organic fertilizer)increased by 0.09%-404.83% compared with CK(no fertilizer),CK1(chemical fertilizer),CK2(bio-organic fertilizer);From the bud stage to the end of blooming,the growth indexes,root,stem,leaf dry weight,photosynthetic related indexes and flower and leaf yield of hemp showed a trend of first increasing and then decreasing with the increase of biological organic fertilizer amount,and F2 was 2.02%-81.82% higher than F1 and F3.At the end of flowering period,the floral yield of F1,F2 and F3 was increased by 4.89%-216.07% compared with CK,CK1 and CK2,and that of F2 was increased by 20.48%-36.98% compared with F1 and F3.The comprehensive analysis showed that 80% fertilizer(360 kg/hm2)combined with 20% bioorganic fertilizer(990 kg/hm2)promoted the growth and photosyn-thetic characteristics of hemp for flower and leaf.
