摘要
重粘性滨海盐土三麦施磷上采用的5种方法中,以KH_2PO_4浸种和根外追肥增产效益最为明显,增产达14.4％。过磷酸钙底施对大麦也有明显的增穗、增粒从而增产的作用。三料过磷酸钙和磷酸二铵做种肥对小麦出苗率无异常影响,且能显著促进叶、蘖及次生根的生长。三料过磷酸钙作壮蘖肥也能起到增穗增产的作用。
Among the 5 methods of applying phesphate fertilizer to wheat and barley in most sticky saline soil of the seashore, seed soaking in solution of KH2 PO4 and spraying this solution on leaves can promote 14.4% to the yields. This effect is most outstanding. Spreading [Ca (H2PO4) · H2O + 7CaSo4] into soil can increase the ears and seeds of grain, therefore promote yield also. Sticking seed with Ca (H2PO4)2 · H2O and NH4PO4 when sowing seed doesn't decrease seedlings, and moreover, promote the growth of leaves, tillers and secondary roots. Spreading Ca (H2PO4)2 · H2O into soil can promote the growth of tiller, then can increase the ears and yields also.
