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。 High-yield and high-efficiency and balanced fertilization techniques were studied in the lime concretion area of ​​the Huaibei Plain. The results showed that the application of Zinc fertilizers had a significant effect on the yield increase based on the application of N and P fertilizers. The yield of wheat surpassed that of peasants using large amounts of organic fertilizers. Balanced fertilization can promote the growth and development of wheat, improve economic traits, significantly increase the levels of soil available nitrogen, available phosphorus and available potassium, and fertilize the soil, thus laying a foundation for the high and stable crop yield.
