川中丘陵水旱轮作土壤&小麦系统CO2排放及其影响因素

Co_2 emission from soil-wheat system in a paddy-dryland rotation area in the central Sichuan Basin and its influence factors

利用静态箱/气相色谱法对川中丘陵区水旱轮作区的小麦进行全生长季CO2排放观测。

CO_2emission from soil-wheat system in a paddy field-dryland rotation area in purple soil were measured by static chamber-gas chromatographic techniques in the central Sichuan Basin .

在红壤区水旱轮作体制下，推荐油菜秸秆全量还田，可以较好地钝化土壤Cd，减少水稻吸收，避免镉米的生产。

In the red soil region of paddy-upland rotation system , recommended the rape straw total returning , can better decreased soil Cd uptake of rice , avoided cadmium rice production .

但冬灌田改为水旱轮作制后，N2O排放量显著增大，RW和RR的N2O年排放量分别是PF的3.7倍和4.5倍。

However , the N_2O emissions were increased after conducting RW and RR systems , which were 3.7 and 4.5 times larger than those of PF .

水旱轮作稻田CH4排放通量比冬水田低54.1%～65.1%；

The mean CH_4 emission fluxes from the paddy fields under rotation was 54.1 % - 65.1 % lower than those under mono-rice cropping during the rice growing season .

该虫在浙江省一年一代，以成虫在土下60～90cm处越冬。研究结果表明，改单一的旱作制为水旱轮作是防治该虫的根本办法。

It has one generation per year and overwinters as adult in soil a depth from 60 to 90 cm in Zhejiang province .
