利用数码相机获取水稻氮营养及其长势长相参数的初步研究

Parameters of Rice N-nutrition and Rice Growing Status Obtained with Digital Camera and Exchangeable Resin

提出了通过交换树脂和数码相机来获取土壤肥力及作物长势、长相参数的方法。结果表明,树脂袋解吸出的速效N与土壤中的速效N间有较好的相关性;数码技术采集的作物生长发育信息(叶色指数)与土壤速效氮含量之间也有良好的相关性;结果还表明,水稻产量在一定范围内和生长发育信息成正相关。

Parameters of rice N-nutrition and ricegrowing status were obtained with exchangeable resin and digital camera. Results indicated that the available-N from resin sack correlated with that from soil and crops growth information collected from digital camera （indices of leaf color） correlated with the content of available-N in soil. Rice yield correlated with its growth information positively in certain range.
