液体复合肥绿迪乐在春小麦上施用实验

Optimum Use Methods of Compound Liquid Fertilizer Ludiler on Spring Wheat

试验结果表明，对春小麦种子浸种和拌种均以绿迪乐稀释１０００倍液为宜，浸种和拌种的发芽势分别相当于对照的９８．９％和１０６．８％、发芽率分别相当于对照的９８．９％和１０１．１％，为各处理最高；叶面喷施的最佳浓度是稀释５００倍液，增产量６６６．５ｋｇ／ｈｍ２、增幅为１６．９％、产投比为各处理最高，达１２．１：１；喷施时期以孕穗期和灌浆期各喷施一次效果最好，增产量为７４６．２ｋｇ／ｈｍ２、增幅为１３．８％，千粒重比对照增加３．９ｇ。

The experiment results showed that the suitable concentration of seed soaking and dressing is one thousandth, with which the germination potentials were equivalent to the 98.9 % and 106.8 % of the check respectively, the germination percentage were equal to the 98 9 % and 101 1 % of the check, respectively The suitable concentration for foliage spraying is one five hundredth, at which foliage spraying can increase yield by 666.5 kg/hm 2, a increase percentage of 16.9 %. As for the spraying time, milk stage and boot stage are the best.
