微肥对番茄及黄瓜作用效果的研究

Effects of Micronutrients Application to Tomato and Cucumber

通过盆栽试验、田间试验及室内分析测定的方法,研究了陕西主要土壤类型土娄土、黑垆土上,单施、配施、微量元素及不同使用方法对番茄、黄瓜生长发育、产量、品质的影响。结果表明:施微量元素锰、锌、硼能促进番茄、黄瓜生长发育,提高产量,改善品质。单施增产10%左右,配施增产20%左右。肥料效果:配施>单施>不施,增产效果:番茄>黄瓜;施微量元素锰、锌、硼降低番茄、黄瓜中NO3--N含量,提高Vc及糖含量,同时施锌肥的黄瓜果实中有益于人体健康的锌含量明显增加。微量元素肥料喷施或土施对增加番茄、黄瓜产量改善品质有同样的作用。

Studied effects of micronutrients application to growth,yield and quality of tomato and cucumber on Shanxi Loessial soil and dark loessial soil by the pot experment,the field plot trials and chemical analysis.The results shoud that micronutrients application may promot growth to raise yield and improve quality tomato and cucumber.Mn,Zn,B divide single application increased yield 10% left-right,coordinated application increased yield 20% left-right.Effects of micronutrients application： coordinated applicationdivide single applicationCK;Effects of plant： cucumbertomato.then,micronutrients application may reduced NO-3-N content and raised Vc,sugar content,Application Zn cucumber fruit Zn content oblication increased,Micronutrients spray or application in soil,there were the same effect to raise yield and improve quality on tomato and cucumber.
