摘要
为揭示覆膜灌溉对河北省春玉米生长生理及产量品质的影响,课题组在衡水市节水灌溉试验站进行了不覆膜(CK)灌溉和覆膜(PM)灌溉的对比试验,通过对不同处理下春玉米叶面积指数(GLAI)、株高、净光合速率(P_(n))、蒸腾速率(T_(r))、胞间CO_(2)浓度(C_(i))、气孔导度(G_(s))和产量等指标的测定,得出了覆膜处理对春玉米生长生理的影响。结果表明:覆膜处理可显著提高春玉米的光合作用速率,有效调节春玉米的生长速度,覆膜处理的春玉米产量显著高于不覆膜处理。
To reveal the effect of film mulching irrigation on the growth physiology,yield and quality of spring maize in Hebei Province,research group,a comparative experiment of non-mulching(CK)irrigation and mulching irrigation(PM)was carried out at the Hengshui Water-saving Irrigation Experimental Station.Through the determination of leaf area index(GLAI),plant height,net photosynthetic rate(P_(n)),transpiration rate(T_(r)),intercellular CO_(2) concentration(C_(i)),stomatal conductance(G_(s)),yield and other indicators of spring maize under different treatments,the effects of film mulching on the growth physiology of spring maize were obtained.The results showed that:film mulching treatment can significantly increase the photosynthesis rate of spring maize and effectively regulate the growth rate of spring maize.The yield of spring maize mulching treatment is significantly higher than that of non-mulching treatment.
