"金正大"硝基双效肥在硝基复合肥的基础上添加控释粒子,保证了作物整个生育期养分充足供应,进一步提高肥料利用率.试验结果表明:与常规施肥相比,产葵花5850 kg/hm2,增产375 kg/hm2,增产率为6.85%,可在葵花上大面积推广应用.

为了解决甘肃省全膜双垄沟播玉米后期脱肥的问题,开展了“金正大”缓释肥一次性施肥研究.结果表明:与农民习惯施肥相比,施用“金正大”缓释肥具有省时省力、增产增效等特点,小区试验增产率达到18.4％,大田示范增产率达到19.0％,同时后期未出现脱肥现象,表明“金正大”缓释肥可在全膜双垄沟播玉米生产中进一步示范推广.

针对肥料生产企业生产现状及销售中所遇到的困难，甘肃省农业节水与土壤肥料管理总站利用肥料生产企业考核之机，组织工商、质检等部门人员深入调研，了解其并利用春秋两季肥料市场专项整治的机会，查找当前肥料市场存在的问题以及解决办法。

为验证成都华宏生态农业科技有限公司生产的"施地佳"土壤调理剂在改善土壤理化性状及在提高玉米产量等方面的作用,进行"施地佳"土壤调理剂在玉米上的应用试验,结果表明,在盐碱地玉米上施用施地佳土壤调理剂,有一定的增产作用。

一、材料与方法 1．示范地概况 示范地选在甘肃省武威市民勤县红沙梁乡高来旺村三社，该区属中温带干旱性沙漠性气候，日照充足，降雨量少，蒸发量大，昼夜温差大。年降雨量110毫米，年蒸发量2643毫米，年日照时数3028小时。

通过＂金正大＂缓控释肥、当地配方施肥与农民习惯施肥进行比较,结果表明：＂金正大＂缓控释肥具有省时省力、增产增效等特点,由于其免于追肥,每亩可节省劳动成本20元;同农民习惯施肥相比,亩产量502～519 kg,增产幅度可达6.8%～18.2%,可在春小麦上大面积示范推广。

大田试验结果表明,在常规施肥的基础上,施用硫酸钾镁肥能够促进啤酒大麦的生长发育,从而提高啤酒大麦的产量,从不同钾肥品种施用效果看,硫酸钾镁肥增产幅度可与等养分的硫酸钾相当,增产效果达显著水平。

有机-无机复混肥料是指含有一定量有机肥料的复混肥料.有机肥料肥效长,具有改良土壤作用,但不能满足高产作物的养分需要,而化学肥料肥效快,但又会因施用不当而引起土壤酸化、板结和有机质含量下降等问题.有机-无机复混肥料既有无机化肥肥效快的一面,又具备有机肥料改良土壤、肥效长的特点.在甘肃省近年来试用效果明显,深受农民欢迎,因而目前有机一无机复混肥的发展极为迅速,已有相当规模,是今后肥料发展的方向之一.

Through experimental research on 2 slow release compound fertilizers of Triabon and Field,the results showed that slow-release effects of the fertilizers was obvious with the nutrient releasing postpone. The effect period of 2 slow release compound fertilizers for spring wheat was more than 100 days, and the effect of abroad Triabon was superior to that of domestic Field. After applying 600 kg/hm~2 of Triabon the yield of spring wheat was 7083.3 kg/hm~2 higher than that of CK, with increasing by 42.5%. Spike grain number and thousand kernel weight increased significantly than CK, secondary was Field. The uptake of N, P and K from grain, stem and leaf of applying slow release fertilizers was higher than that of applying simple bulk-blend fertilizer(S), with increasing by 2.4%～14.8%,5.6%～21.2%,8.0%～11.3%,respectiviely. The utilization efficiency of N,P and K nutrition of slow release fertilizer was 37.2%～60.9%,24.7%～40.3% and 71.3%～81.9% , and reduced fertilizer loss.

The research was to probe into effects of organic-inorganic compound fertilizer on the yield and quality of greenhouse with several species of fruit vegetables. The results showed that the yield and quality of sunlight greenhouse vegetables receiving organic-inorganic compound fertilizer were increased. The yields of cucumber、pepper and tomato were increased 16.44%、17.23% and 21.54% than CK . NO_3~--N were decreased 111 mg/kg、213 mg/kg and 223 mg/kg than CK.
