营养调控措施对云南玉米产量与品质的影响

Different Fertilizer Treatments on Yield and Quality of Maize in Yunnan Province

我们采用田间小区试验研究了配方肥和其他营养调控措施对玉米农学性状、产量、收益、品质和土壤养分含量的影响。结果表明,配方肥+Mn处理是最佳的处理,其产量、净收益均是所有处理中最高的,其次为配方肥+B处理,第三为配方肥处理。配方肥、配方肥+Mn和配方肥+有机肥三个处理的品质稍好于其他处理。配方肥+有机肥可使土壤养分含量得到改善。因此,在B和Mn含量较低的本试验区中,配方肥+B或配方肥+Mn处理可使玉米得到优质高产。

A field experiment was conducted to investigate effects of different fertilizer treatments on agronomic traits,yield,quality and profit of maize.The results indicated that the formula fertilizer+Mn produced the highest yield and profit,and followed by formula fertilizer+B and formula fertilizer.Maize quality in the treatments of formula fertilizer,formula fertilizer+Mn and formula fertilizer+mature was slightly better than the other treatments.Addition of formula fertilizer+manure improved soil fertility.Therefore,in the areas where B and Mn are deficient,it is indispensible to add Mn and B to achieve high yield and quality maize.
