| 1. | Accumulation of excessive exchangeable potassium is from the use of mixed fertilizers or manure . 由于施用混合肥料或厩肥使交换性钾过渡累积。 |
| 2. | . . mixed fertilizers . calcium and or magnesium liming materials . types and specifications 混合肥料.含钙和 |
| 3. | . mixed fertilizers - calcium and or magnesium liming materials - types and specifications 混合肥料.钙肥和 |
| 4. | The effect and mechanism of zeolite blended mixed fertilizer on yield increment in crops 沸石载体复混肥对作物的增产效应及机制研究 |
| 5. | According to the rapid development of mixed fertilizer , our factory made close cooperation with the fourth design institution of chemical ministry , shanghai chemical academe and nanjing chemical design institution 根据复混肥的迅速发展,我厂先后同化工部第四设计院、上海化工研究院、南京化工设计院等科研单位紧密合作,积极开发新产品。 |
| 6. | The result showed that organo - inorgano - mixed fertilizer could increase the quantity of availability , strengthen the activity of proteinase , sucrase , urase and peroxidase in the sugarcane roots , and increase the sugarcane yield and sugar content 结果表明,有机无机肥料配施,可提高土壤有效养分的含量,激活土壤蔗糖酶、脲酶、蛋白酶、过氧化物酶的活性,促进甘蔗生长与蔗糖分的累积,对甘蔗增产增糖有积极的作用。 |
| 7. | Used dynamics equation to express the relation between the accumulation amount of no 3 - n leaching and time : urea , ammonium - bicarbonate and composed fertilizer can be expressed as equation yt1 / 2 = a + bt , complex mixed fertilizer can be expressed as equation 1 / y = a + bl / t . the accumulation leaching quantity of no 3 - - n with urea , ammonium - bicarbonate , composed fertilizer and complex mixed 随时间t的变化用方程进行拟合,结果表明ck 、碳按和复混肥处理,以双曲线方程l / y二a + bl八拟合效果最好,而尿素和复合肥处理则以抛物线方程y , ’ / 2 = a十bt拟合效果最好。 |
