生物有机肥对木薯生长和块根产量的影响

试验以木薯品种辐选01和利达生物有机肥为材料，就生物有机肥对木薯生长和块根产量的影响进行研究。结果表明：生物有机肥对于提高木薯的株高、茎径和叶面积指数都有不同程度的促进作用。在生长后期，各生物有机肥处理的株高、茎径和叶面积指数均比对照的高。另外，生物有机肥能明显提高木薯块根的产量，其中750kg/hm2生物有机肥处理的产量最高，比对照增产70.88%；450kg/hm2、600kg/hm2、900kg/hm2生物有机肥处理分别比对照增产5.06%、49.36%、20.88%。

The Effects of Bio-organic Fertilizer on Plants Growth and Root Tubers Yield of Cassava

The effects of bio-organic fertilizer on plants growth and root tubers yield of cassava were studied in this experiment, of which the cassava variety FUXUAN01 and the bio-organic fertilizer produced by LIDA company were used as materials. The results showed that the effects of bio-organic fertilizer treatments on the plant height, the stem diameter and the leaf area index of cassava showed more or less promoting effect. At the late period, the plant height, the stem diameter and the leaf area index of the bio-organic fertilizer treatments were higher than that of the control. Besides, the bio-organic fertilizer treatments increased the root tubers yield. The root tubers yield of the 750kg/hm2 bio-organic fertilizer treatment was the highest which increased the root tubers yield by 70.88% higher than that of the control. The 450kg/hm2,600kg/hm2,900kg/hm2 bio-organic fertilizer treatments increased the root tubers yield by 5.06%, 49.36% and 20.88% respectively higher than that of the control.
