田间实验 meaning in English
field experiment
Examples
- A randomized complete block design ( rcbd ) has been used under the field conditions to compare the effect of four treatments : 1 ) entire quantity of straw returned to the soil , but not cut into pieces ( treatment a ) , 2 ) half quantity of straw returned , not cut into pieces as in treatment a ( treatment b ) , 3 ) half quantity of straw cut into pieces returned ( treatment c ) , 4 ) ck ( treatment d ) , without any straw returned to the filed
田间实验采用随机区组法，分四种情况： 1 )全量整株稻草还田； 2 )半量整株还田； 3 )半量切碎还田4 )对照，即除根茬外无额外稻草还田四个处理。试验结果表明，除处理2外，所有处理对土壤有机质的影响不明显，但稻草还田处理降低了土壤的容重，这意味着土壤的孔隙度增加了。 - The physiological reaction of c . junos under iron stress in field experiments , c . junos manifested itself as tolerant to iron stress . no chlorosis symptom was not found in its leaves when it was grown in a soil with ph 7 . 8 . in contrast , severe chlorosis was found in the control plant p . trifoliata grown under the same soil conditions , and leaf chlorophyll content as an indicator for the degree of fe deficiency in p . trifoliata was much lower than in c . junos
主要的研究结果如下： 1 ：铁胁迫下香橙的生理反应研究香橙在田间实验中表现耐缺铁，在ph7 . 8的土壤中生长正常，叶片无任何缺铁症状；但对照植物枳在同样土壤条件下却表现出明显的缺铁症状，作为缺铁程度指标的叶片叶绿素含量极显著低于香橙。
