- 摘要:
- 以重庆市万州区甘宁镇中屯、牌楼村柑橘园建设为例,通过对水稻田改种柑橘的立地条件(土壤层次、土壤养分、土壤厚度)及柑橘根系分布状况的调查分析,提出了水稻田改种柑橘的田块改造工程设计方案。结果表明:研究区土地利用类型以水田为主,坡度较为平缓,宜采用开沟做畦法,开挖柑橘定植的定植沟宽、深分别为0.4 m和1.6 m,每隔8 m修建1条排水沟,2条排水沟之间开挖箱沟1条,筑垄畦时,将开沟土壤及表层土壤回填放于柑橘定植的周围,形成0.4 m高的畦,使有效土层厚度达到0.8 m;三峡库区水稻田改种柑橘的田块改造工程设计应结合当地坡度、土壤性质及柑橘根系分布状况综合分析,合理确定柑橘种植田块改造的各项参数。
- Abstract:
- Through investigating soil layers,soil nutrient,soil thickness and distribution of citrus root,engineering design of citrus orchard’s planting field in paddy field in Ganning Town,Wanzhou County of Chongqing were discussed.The results showed that paddy field was the main land using type and the slope was gentle in the study area,ditching of soil improvement by means of ridge and furrow should be adopted in paddy field.Digging of planting furrow width and depth were 0.4 m and 1.6 m,respectively,with the drainage ditch was built in every 8 m.The field drain was built between two drainage ditch,and then backfill soil of digging and surface soil around the planting furrow,in order to made 0.4 m ridge reach and 0.8 m soil thickness.According to the slope,soil properties and citrus roots,the engineering design of planting field of citrus orchard in paddy field should determine the parameters rationally.
