【摘要】 为探讨二氢卟吩铁拌种和喷雾对花生生长及产量的影响，明确使用剂量。采用不同浓度二氢卟吩铁对花生拌种及在不同生长期喷雾2种方式处理。结果表明，二氢卟吩铁种子拌种和喷雾均能促进花生生长、分枝，增加单株的角果数，提高果仁重，分别增加花生产量12.38%～14.29%和33.33%～55.87%。从经济角度考虑，拌种适宜用量为每千克花生0.02%二氢卟吩铁SP 0.20～1.00 g，喷雾适宜使用浓度0.02%二氢卟吩铁可溶性粉剂1000～5000倍。更多还原

【Abstract】 To clearly define the dosage and investigate the effect of seed dressing and spray with iron chlorin on the growth and yield of peanut, seed dressing with different concentrations of iron chlorin and spray treatment at different growth stages were used in this research. The results show that both seed dressing and spray of iron chlorin would promote peanut growth and branching, increase the number of corner fruit per plant and kernel weight, and increase peanut yields by 12.38%-14.29% with seed treatment method and 33.33%-55.87% with spray method. From the perspective of economy, the appropriate amount of seed treatment is 0.02% chlorin SP0.20-1.00 g per kg peanut, and the appropriate concentration of spray is 0.02% chlorin SP 1000 to 5000 times.更多还原
