摘要
研究了淮北平原砂姜黑土区小麦高产高效平衡施肥技术 ,结果表明 ,在施用氮磷肥的基础上配施锌肥具有显著的增产效果 ,小麦产量超过施用大量有机肥的农民习惯施肥产量。平衡施肥能促进小麦生长发育 ,改善经济性状 ,显著提高土壤碱解氮、有效磷和速效钾含量水平 ,培肥地力 ,为作物高产稳产打下地力基础。
The field trial was conducted, which studied the wheat balanced fertilization of high-yield and high-efficiency. The result showed that applying zinc had remarkable effect on increasing production on the basis of cooperating with nitrogen and phosphate fertilizer, and wheat yield surpassed that from peasant habital fertilization which applied enormous organic manure. The balanced fertilization could promoto wheat growth, improve economic properities, notably increase the content of alkli-nitrogen, available phosphorus and potassium in soil, and fertilize the soil. It laid a foundation for crop high yield.
