【摘要】 为了解农残降解增产液在大蒜上的使用效果,以喷清水为对照,设计了5个农残降解增产液处理的对比试验。结果表明:施用农残降解增产液的处理蒜头产量比对照明显提高,增产幅度6.4%~15.4%,其中处理3产量最高,达1870 g/m2,比CK增产250 g/m2。蒜薹产量也表现出同样规律,增产幅度34~57 g/m2,增加收益0.07~0.12元/m2;经济效益明显,所有施用农残降解增产液的处理均比对照收益增加,分别增加1.73、2.25、0.84、1.97、0.95元/m2,本试验中处理3收益最高,达到14.50元/m2。大蒜施用农残降解增产液提高了大蒜特、一级率;黄叶片数减少,绿叶数增多,增强了大蒜后期抗疫能力。处理3最优,在常规施肥基础上,用0.75 m L/m2的农残降解增产液,对清水90 g/m2处理土壤,在返青期、抽薹后叶面喷施农残降解增产液各0.3 m L/m2农残降解液,对清水90 g/m2喷洒是比较经济有效的使用方式。更多还原

【Abstract】 In order to understand the effect of"agricultural residues degradation and increase productionagent"on garlic, five treatments were designed with water as control. The results showed that the yield of garlichead obviously increased after the application of this agent with the increase rate of 6.4%-15.4%, treatment 3had the highest yield of 1870 g/m2, which was 250 g/m2 higher than that of CK. The yield of garlic sprouts alsoshowed the same rule, the increase was 34- 57 g/m2, and the income increased 0.07- 0.12 yuan/m2. Theeconomic benefit increase was obvious, compared with that of CK, the income increase of treatments applied"agricultural residues degradation and increase production agent"was 1.73, 2.25, 0.84, 1.97 and 0.95 yuan/m2,respectively. The highest income was treatment 3 of 14.50 yuan/m2. Special grade rate and first-grade rateincreased after the application of this agent, yellow leaf number decreased, while green leaf number increased,the ability to resist disease in the late period was enhanced. Treatment 3 was the optimal in this experiment,under conventional fertilization, 0.75 m L/m2"agricultural residues degradation and increase production agent"mixed with 90 g/m2 water for soil treatment and 0.3 m L/m2"agricultural residues degradation and increaseproduction agent"mixed with 90 g/m2 water after the green period and bolting was the most economical andeffective way.更多还原
