施肥模式对春玉米和小白菜的产量和品质的影响

为了寻找一种使作物高产优质的施肥模式，采用大田小区试验方法，在洞庭湖地区研究了7种不同施肥模式对春玉米和小白菜的产量和品质的影响。结果表明：与不施肥对照相比，20％的沼肥和30％的堆肥2种施肥模式均可显著改善春玉米和小白菜的农艺性状，分别使春玉米产量提高了69．3％和73．0％，粗蛋白含量提高了42．1％和36．5％，粗淀粉含量提高了12．9％和9．6％；同时分别使小白菜产量提高了98．3％和107．8％，Vc含量提高了48．4％和67．5％，可溶性糖含量提高了26．3％和40．8％。因此，这2种施肥模式都可以在生产中加以推广应用。

Effects of Different Fertilizing Modes on Yield and Quality of Spring Maize and B. chinensis L.

In order to explore an optimum fertilizing mode that could help crop high-yield and quality, field experiments were conducted to study the effects of seven different fertilizing modes on yield and quality of spring maize and B. chinensis L in Dongting lake Area. The results showed that compared with control group that do not fertilize, two fertilizing modes that 20% biogas manure and 30% compost could improve agronomic traits of spring maize and B. chinensis L significantly, which improved spring maize's yield by 69.3% and 73%, crude protein content by 42.1% and 36.5%, crude starch content by 12.9% and 9.6%, respectively; meanwhile, which improved B. chinensis L's yield by 98.3% and 107.8%, V_c content by 48.4% and 67.5%, soluble sugar content by 26.3% and 40.8%, respectively. It indicated that these two fertilizing modes could apply and popularize to production.
