| 摘 要： | 采用大田小区试验,以不施肥（CK1）和施用等NPK养分化肥（CK2）为对照,研究了掺混型缓释肥对玉米产量和品质的影响。结果表明：施用掺混型缓释肥可以明显降低秃尖长度,增加穗粒数、穗粒重和千粒重,显著提高玉米产量;玉米收获时植株含氮量和含钾量明显增加,含磷量变化不大;有效提高土壤速效氮和速效磷含量;提高玉米籽粒品质。

| Abstract: | An experiment was conducted in field to study the effect of blending type slow-release fertilizer on the yield and quality of maize compared to treatments of no fertilizer(CK1) and fertilizer(CK2).The results showed that the length of barrenness could be decreased.The grains number per ear,ear weight,1000-grain weight and yield could be increased.Concentration of N and K in the plant was increased during the harvest.However,the concentration of P in the plant was the same as contrast.After blending type slow-release fertilizer was applied in the soil,the content of valid N and P in the soil was increased.The quality of maize grains was improved. |
