摘要
为探索小麦配方施肥效果,掌握配方施肥用量,提高氮肥、磷肥和钾肥利用率效果,2012-2013年进行小麦配方肥试验。在中等肥力情况下,目标产量9000 kg/hm2,选择配方施肥,基肥(14-22-6)675kg/hm2,拔节期追肥(30-0-10)600kg/hm2为最佳。
Formula fertilization and normal fertilization experiments from 2012 to 2013 to study ciency of formula fertilization and the optimum fertilizing amount to increase the utilization efficiency gen, pHospHate and potash. The result of formula fertilization, namely base fertilizer （ 14 - 22 - 6） hm^2, topdressing at jointing stage （30 -0 -10） 600 kg/hm^2, is best when the target production is hm2 under middle fertility circumstance. the effi- of nitro- 675 kg/ 9000kg/hm^2 under middle fertility circumstance.
