大豆在白浆土中的吸肥规律及施肥对其产量的影响

白浆土;释放规律;吸肥规律;互作效应
摘  要:
白浆土中的速效氮和钾的释放高峰在苗期,速效磷则在大豆的整个生育期变化不大,而大豆对氮、磷、钾的吸收高峰均在花期;N、P、K三要素及元素之间互作对大豆生长均为正效应,由此可为合理施肥提供理论依据。

Albic soil, Releasing law, Absorbing law, Interaction effect
摘  要:
Releasing peak of quick-acting N and K in Albic soil is at seeding stage , Releasing amount of quick-acting P almost has no change during the whole growth period ; absorbing peak of soybean's nutrient-N, P, K are measured at flowering period; Interaction effect of N,P,K is positive to soybean's growth .According to these characteristics, we can provide theoretical basis for reasonable technology of applying fertilizer.
