| 摘 要： | １９９２～１９９４年在河南省三大土类区（褐土、潮土、砂姜黑土）进行了钾肥配合秸秆还田试验。结果表明，施钾对冬小麦、夏玉米、夏大豆均有增产效果，但不同土类、不同作物增产效果不一。总的来看，夏大豆＞夏玉米＞冬小麦；砂姜黑土＞潮土＞褐土。除洛阳褐土玉米外，单用秸秆还田就能显著增加作物产量。但三种作物都是施钾配合秸秆还田处理的产量最高，施钾或施钾配合秸杆还田对作物生长发育均有促进作用，并能减轻小麦、大豆的病虫危害。

| Abstract: | The fixed site trials,conducted in three soils of types Henan province
from1992 to 1994 showed that K fertilization had a certain yield increasing effect on
winterwheat, summer corn and summer soybean.On the whole,the order of yield increasingwas
soybean>corn>wheat and Shajiang black soil(SS) > fluvo-aquic soil(FS)>cin-namon soil (CS
).Application of straw alone can increase crop yield significantly exceptcorn yield on Luoyang
CS.However, application of K and straw together (K ST ) isstill superior to that of other
treatments. Treat ments of K ST and K promoted thegrowth of crop and decreased the disease
damage on wheat and soybean. |
