Abstract
本研究之目的在探討穀物收穫量測定器(Cropton)應用於臺灣水稻產量評估之可行性，試驗採用兩種方法進行取樣，方法1為本機器標準取樣法（每取樣田依其取樣方式取6個取樣小區，每取樣小區取10株水稻，總計取60株水稻），方法2為臺灣省糧食局採用之取樣方法（每取樣田位其取樣方式取4個取樣小區，每取樣小區取25株水稻，總計取100株水稻），結果發現不同取樣方法所得機器推估產量〔Y1（方法1）及Y2（方法2）〕分別與其小區調查產量〔Y1（方法1）及Y4（方法2）〕間的相關係都已高達0.93以上，且機器推估產量與小區調查產量的迴歸決定係數(R^2)值極高，所以推論本機器可代替小區調查產量用於推估臺灣水稻，機器推估產量之簡單迴歸模式分別為Y3=60.0059+0.9609(Y1)，R^2=0.940；Y4=99.7731+1•0268 (Y2), R^2=0.866。The objective of this research was to evaluate the possibility of use of Cropton for prediction of rice yield production in Taiwan. Two sampling methods were used inthe experiment, Method 1 was the Cropton standard sampling method (Each location six plots and each plot 10 rice hills were sampled); Method 2 was the sampling method used by Province Food Bureau ROC. (Each location four plots and each plot 25 hills rice were sampled). The results showed that the estimated yields by Cropton (Y1, Y2) were highly and significantly correlated (above 0.93) with square meers of yields (Y3, Y4). Also, the regresssion coefficient between the estimated yields by Cropton and the square meters of yields are very high. This indicated that Cropton Cropton can be used in place of square meters of yields to predicate rice yield capacity. The simple regression odels are Y3=60.0059+0.9609 (Y1), R2=0.940; and Y4=99.7731+1.0268 (Y2), R2=0.866, respectively.
