保护地菜田土壤氮素淋溶阻控措施及其效果研究
摘要
在保护地菜田条件下
以水果苤蓝为供试作物
研究优化施肥、C/N调控、种植填闲作物等3种不同措施对土壤硝态氮累积与淋溶的影响。结果表明
种植当季
优化施肥和C/N调控处理均可有效阻控硝态氮淋溶。综合考虑水果苤蓝生长期和填闲/休闲期
3种措施阻控硝态氮淋溶的强度
由强到弱依次为:种植填闲作物>优化施肥>C/N调控。建议控制施肥量的同时
采用合理的管理方式
多方面阻控硝态氮的累积与淋溶
保护环境安全。
Abstract
In facility vegetable field
an experiment with kohlrabi for selected crops had been carried out
to research the effect of three different measures
which were fertilization optimization
C/N regulation and catch crops planting(sweet corn)
on the nitrate nitrogen accumulation and leaching in soil.The results indicated that fertilization optimization and C/N regulation were effective measures to reduce and control nitrate leaching in the kohlrabi planting season.The effects on the nitrate nitrogen leaching resi...
