黑曲霉菌生物肥对花生植株生长动态的影响

Effects of Aspergillus niger Bio-Fertilizer on Growth Dynamics of Peanut Plants

摘要: 在田间试验条件下，以青花7号花生品种为材料，系统研究了黑曲霉菌生物肥对花生植株生长动态的影响。研究结果表明：在减施复合肥10%加施等量黑曲霉菌生物肥的条件下，仍可保证花生植株良好生长，其主茎高、侧茎长、主茎叶数、侧茎叶数、分枝数虽不及常规复合肥处理的，但显著高于同等减肥条件下加施等量有机肥的；减施复合肥20%加施黑曲霉菌生物肥的上述性状也明显高于减肥10%加施等量有机肥的。减施复合肥10%加施等量黑曲霉菌生物肥可明显增加有效分枝数，有利于增加单株结果数量。

Abstract: The effects of Aspergillus niger Bio-fertilizer on the growth dynamics of peanut plants were systematically studied under field conditions with Qinghua 7 peanut cultivar as material. The results showed that under the condition of reducing compound fertilizer by 10% and applying the same amount of Aspergillus niger bio-fertilizer, peanut plants could still grow well. Although the main stem height, lateral stem length, main stem leaf number, lateral stem leaf number and branch number were not as good as those of conventional compound fertilizer treatment, they were significantly higher than those of the same amount of organic fertilizer under the same condition of reducing weight. Characters were also significantly higher than those of 20% weight loss plus the same amount of organic fertilizer. Decreasing compound fertilizer by 10% and applying the same amount of Aspergillus niger bio-fertilizer could significantly increase the number of effective branches, which was beneficial to increase the number of fruit per plant.
