| 摘 要： | 采用田间试验方法,以板栗燕山早丰为供试品种,设置5个处理:空白对照(CK)、等养分无机肥(WJ)、等养分栗蓬栗叶-菌渣-秸秆-鸡粪混合堆肥(BYZ)、菌渣鸡粪堆肥(ZF)和栗蓬栗叶-菌渣-鸡粪堆肥(BZ),研究有机物料深施对山地板栗园褐土(分0～20 cm和20～40 cm两个土层)团聚体分布、土壤总孔隙度、土壤含水率、土壤水势及板栗产量的影响,为产区合理利用有机养分资源提供依据。结果表明:(1)土壤团聚体均以0.5 mm和0.053～0.25 mm为主,含量分别为31.46%～41.87%、34.63%～49.98%,土壤含水率、土壤水势均随时间的推移呈现先升高后降低再升高的变化趋势,且在7月初均最低;(2)与CK和WJ处理相比,有机物料处理0.5 mm的大团聚体含量分别增加7.10%～33.09%、1.10%～25.84%,而0.053～0.25 mm微团聚体含量显著降低,分别较CK和WJ处理降低13.58%～30.72%、5.08%～19.83%,板栗产量及各土层土壤平均质量直径(MWD)、0.25 mm团聚体含量(R0.25)显著增加,各土层土壤含水率、土壤总孔隙度总体表现为BZBYZZF,与产量大小排列一致;(3) 20～40 cm土层平均土壤含水率和平均土壤水势与板栗产量呈显著正相关(P0.05)。(4)整体研究表明,栗蓬栗叶-菌渣-鸡粪堆肥(BZ)不仅能改良土壤结构和提高土壤保水性,而且板栗增产效果最显著,是产区好氧堆肥原料体系和山地板栗园深施实践的较佳选择。
