| 6. | So considerable errors might occur if water dissolution rate method was used to estimate the fertilizer efficiency although the method can make quick comparisons of nutrient release rates among different crfs / srfs 水中溶出率虽可以快速比较不同控/缓释肥的溶出速率,但用以估测肥料在田间的实际肥效,则产生较大的误差。 |
| 7. | Termed a reactive layer coating membrane ( rlc ) , laboratory evidence suggests a predictable nutrient release since a concurrent absorption of water into , and diffusion of , solubilized fertilizer material out through the highly crosslinked membrane continues until nutrient release is complete ( table 1 ) 对于一种反应层包膜( rlc ) ,实验室研究表明,因为在养分完全释放之前,随着水分吸收,被溶解的肥料通过高度交织的膜不断向外扩散,故养分的释放是可以预测的(表1 ) 。 |
| 8. | This paper aimed at present status that most researches assembled in chemical products , adopted different determine methods , represented the transformation characteristic of nitrogen among water and soil of the sulphureous urea , confirmed the nutrient release speed , found out the optimum determine method in agricultural production application 针对目前对缓释肥料释放特性的研究集中在化工制作领域这一现状,采用不同的测定方法,阐明含硫尿素中的养分氮在水及土壤中的转化特点,确定养分的释放速率,以求找出适合农业生产应用的方法。 |
| 9. | The structure of fertilizers was studied by scaning electronic microscopy ( sem ) , and the nutrient release characteristics were studied using water dissolution rate method and soil column leaching method . [ result ] the 24 hours n water dissolution rates of sapcus were 18 . 22 % - 83 . 87 % , and n accumulated leaching rates in four weeks were 40 . 91 % - 65 . 38 % , which decreased by 5 . 21 % - 40 . 68 % compared with that of urea under the same experiment conditions 方法以不同类型和吸水倍率的高吸水性树脂为包膜材料,以大颗粒尿素和改性矿物包膜尿素为原料肥料,研制出高吸水性树脂单层包膜尿素、高吸水性树脂复式包膜尿素系列产品,利用电子扫描电镜研究了其结构特征,并以水中溶出率法和模拟土柱淋溶法研究其养分释放特性。 |
