不同栽培方式对田家紫皮大蒜产量的影响

Effects of Different Cultivation Methods on the Yield of Tianjia Purple Garlic

为提高内江地理标志产品田家紫皮大蒜产量,改善土壤结构,开展了不同播种方式、化肥减量和增施有机肥、大蒜分级消毒处理等多种栽培试验,以研究不同栽培方式对大蒜产量的影响。结果表明:采用浅宽沟撒播和条播的方式有助于增产,其中以浅宽沟撒播并覆盖稻草效果最好,大蒜667 m^(2)增产达到35.4%;在传统穴播方式下,减施化肥和增施有机肥可以保证大蒜产量与CK相一致,采用浅宽沟撒播大蒜产量则可以显著增加19.7%;大蒜消毒分级处理并配合化肥减量增施有机肥,产量可以显著提高22.5%以上,其中浅宽沟撒播增产效果最显著,达到26.8%。

In order to increase the yield of Tianjia purple garlic,a geographical indication product in Neijiang,and improve the soil structure,a variety of experiments of cultivation methods were carried out,including different planting methods,chemical fertilizer reduction and organic fertilizer increasing,and garlic grading disinfection treatment,to study the effects of different cultivation methods on yield of garlic.The results showed that the methods of shallow and wide furrow sowing and drill sowing were helpful to increase the yield of garlic,among which the effect of shallow and wide furrow sowing with covering straw was the best with an increase yield of 35.4%per 667 m^(2).By reducing the application of chemical fertilizer and increasing the application of organic fertilizer,the yield of garlic could be guaranteed consistent with CK under the traditional hill-drop sowing method,while the yield of garlic could be significantly increased by 19.7%by using shallow and wide furrow sowing.Garlic disinfection and grading treatment,combined with fertilizer reduction and organic fertilizer increasing application,could significantly increase yield of garlic by more than 22.5%・The effect of shallow and wide furrow sowing was the most significant,which reached 26.8%.
