印度农学家L SAIKIA和病理学家B PARUAH经过试验,记录下灌浆期水稻鞘病(Rhizoctonia)发生率(％)和每块田稻谷产量(公担/公顷),经相关和回归分析,显著性检验,找出了所获稻谷产量与鞘病发生率之间的相关系数,提出了一个由鞘病发生率预测由此而引起的稻谷产量损失的方程式: Y=58.46-0.382X
Indian agronomist L SAIKIA and pathologist B PARUAH were tested to record the incidence (%) of Rhizoctonia at the grain filling stage and the paddy yield (mmh / ha) per pad. Correlation and regression analysis showed that the significance Test to find out the correlation coefficient between the yield of rice and the incidence of sheath disease and put forward a formula for predicting the yield loss of paddy due to the occurrence of sheath disease: Y = 58.46-0.382X
