摘要
通过 1999～ 2 0 0 0年在黔中地区旱地黄壤上对有机肥和磷肥配合施用方式的试验 ,明确了水溶性磷肥是黄壤旱地首选磷肥品种 ,探明了磷肥与有机肥对植株根部土壤环境、植株体内磷水平的影响及肥料效应。同时 。
By trials, on upland yellow earth in central Guizhou, of combined application of manure and phosphate fertilizers from 1990 to 2000, it is ascertained that the water solvable phosphate fertilizer is the first choice for upland yellow earth. The phosphate content of both root area and plant body has been probed under the combination of phosphate and manure, heaping and fermenting ahead of application, as well as yield response. Finally, the interaction between manure and phosphate has been discussed.
