摘要:

【目的】研究微生物菌剂对核桃叶片生理及光合特性影响,为微生物菌剂在新疆阿克苏地区核桃上应用提供科学依据。【方法】以14年生疏散分层形温185核桃为材料,共设置6个处理,分别为枯草芽孢杆菌30 g/株(T1)、哈茨木霉菌30 g/株(T2)、枯草芽孢杆菌40 g/株(T3)、哈茨木霉菌40 g/株(T4)、枯草芽孢杆菌20 g/株+哈茨木霉菌20 g/株(T5)和清水对照(CK)。测定核桃叶片叶面积、叶长、叶宽、鲜重、干重、叶绿素(SPAD)、光合特征等指标,分析不同用量及种类的微生物菌剂对核桃叶片的影响。【结果】在T5处理下核桃叶片生长指标表现最优,T5处理下叶片养分含量氮、磷、钾出现最大值,较对照高出65.68%,61.14%和57.47%;该处理下叶片叶绿素含量与CK呈显著差异,较对照高29.38%,且提高了叶片净光合速率、气孔导度、蒸腾速率,较对照分别高22.57%、21.16%和65.58%。【结论】沟施枯草芽孢杆菌和哈茨木霉菌各20 g处理促进核桃叶片生长及养分含量和提高光合性能的效果最佳。

Abstract:

【Objective】 To explore the effects of microbial microbial agents on the physiological and photosynthetic characteristics of walnut leaves,and to provide scientific basis for the application of microbial microbial agents on walnut in Aksu area. 【Methods】 A total of 6 experimental treatments were set up with 14-year old walnut "Wen185" as the test material,which were 30 g/ strain of Bacillus subtilis (T1), 30 g/ strain of Trichoderma hartzii (T2), 40 g/ strain of Bacillus subtilis (T3), 40 g/ strain of Trichoderma hartzii (T4), and 30 g/ strain of Trichoderma Hartzii. Bacillus subtilis 20 g/ strain + Trichoderma harziensis 20 g/ strain (T5), water control (CK). Then, leaf area, leaf length, leaf width, fresh weight and dry weight were measured. After thatn, chlorophyll (SPAD), photosynthetic characteristics and other indicators were determined and the effects of different amounts of microbial inoculants on walnut leaves were analyzed. 【Results】 Under T5 treatment, the area, length, fresh weight and dry weight of walnut leaves were significantly higher than those of control, which were 31.75%,11.55%,90.83% and 166.66% higher, respectively. Leaf nutrient contents of nitrogen, phosphorus and potassium showed the maximum value, which was 65.68%,61.14% and 57.47% higher than that of the control. Chlorophyll content and photosynthetic characteristics index parameters were also increased under this treatment. 【Conclusion】 Trench application of 20 g on each of Bacillus subtilis and Trichoderma harziana promote the growth,nutrient content and photosynthetic performance of walnut leaves. In this experiment, the combination of Bacillus subtilis 20 g and Trichoderma harziana 20 g has the best effect.
