淮北不同地力水平麦茬田上施氮量对超级稻产量形成的影响OA北大核心CSCDCSTPCD
Effects of nitrogen application rate on the yield and yield formation of super rice in ricewheat double cropping system under different levels of soil fertility in Huaibei region.
以江苏淮北稻区稻麦两熟的单季稻为对象,研究了不同地力上的施氮量对超级稻产量及物质生产的影响,为不同地力土壤合理施氮肥提供依据.以该区有代表性的超级稻中熟中粳徐稻3号为供试材料,研究了麦茬田高、中、低3种地力水平上不同施氮量对水稻产量及其构成因素、以及对水稻群体质量的影响.结果表明:施氮量与水稻产量之间呈极显著的二次曲线关系(r高=0.959**,r中=0.971**,r低=0.981**),且高地力土壤水稻产量显著高于中地力土壤,中地力土壤的水稻…查看全部>>
Taking the single cropping of rice in rice-wheat double cropping system in the Huaibei region of Jiangsu Province as the object, this paper studied the effects of different nitrogen application rates on the yield and matter production of super rice under different levels of soil fertility. Super rice Xudao 3, a representative middle-season and middle japonica rice variety in the region , was selected as the test material , and the soils selected had fertilit…查看全部>>
