【摘要】 1999～ 2 0 0 0年 ,就德国引进的缓释肥和自研缓释肥肥效进行了研究。结果表明 ,自研缓释肥与德国缓释肥料 2号 (N16 +P8+K12 )的肥效较高 ,较好地协调了旱地小麦产量三因素之间的关系 ,较对照 (当地习惯用肥 )增产 2 1.5% ,水分生产率较不施肥提高 10 %。更多还原

【Abstract】 Yield increasing effects of slow release fertilizers made in Germany and Institute of Soil and Fertilizer Research,Shanxi Academy of Agricultural Sciences were studied in 1999～2000.The results showed that these fertilizers had high effects and adequately coordinate the yield components on rainfed wheat.Compared with the control,they increased yield by 21.5%.The Water use efficiency was increased by 10% compared with the treatment without fertilizer application.更多还原
