有机肥替代不同比例化肥对麻竹笋产量的影响

在福建省南靖县开展了麻竹笋用林有机肥替代化肥的田间试验,采取氮总量控制,设置有机氮替代不同比例无机氮的试验处理,分析了各处理之间出笋数量和竹笋产量的差异性。结果表明,在总氮施入量一定的情况下,不同比例的有机氮施入量对增加出笋数量和竹笋产量的影响排序表现为67%>0%>100%>50%>CK>33%;当有机氮施入量占67%时出笋的数量和产量分别比单施化肥增加6.1%和10.3%,对促进麻竹笋生长和产量提升最明显。

Effect of Organic Fertilizer Replacing Chemical Fertilizers of Different Proportions on Shoot Yield of Dendrocalamus latiflorus

A field experiment is conducted in which the organic fertilizer is used to replace chemical fertilizers of different proportions for Dendrocalamus latiflorus shoot forest in Nanjing county, Fujian province. The differences in shooting number and shoot yield among various treatments are analyzed by applying the total nitrogen control method. The results showed that when the total nitrogen application is set at certain amount, the application amount of organic nitrogen of different proportions has different effect on the increase of bamboo shooting quantity and shoot yield, which can be ordered as 67%>0%>100%>50%>CK>33%. When the application amount accounts for 67%, the shooting number and shoot yield increase by 6.1% and 10.3%, respectively, compared with those under the mere application of chemical fertilizer, which can improve the growth and yield of D. latiflorus the best.
