作物系数 meaning in English
crop factor
Examples
- The relationship established between kc and meteorological data indicated that crop coefficient ( kc ) increases as wind speed increases , or net radiation or relative humidity declines
作物系数和气象资料的线性拟合关系表明,作物系数随风速和冠层净辐射的增大而减小,随相对湿度的增大而增大。 - Including irrigation time , frequency , and quantity of water , of which based on the evapotranspiration rate and crop coefficients in different months and the rank of visual appearance of different date
根据草坪质量与土壤含水量、土壤水势的相关性及作物系数、蒸发量等参数,准确计量其灌水时间、灌水量和灌水频率。 - Drip irrigation under mul : h is a new irrigation method , as utiliz e the advance of drip irrigation and plastic film cultivation technique . the conditions influenced crop water requirement are changed in drip irrigation under mulch , thus crop water requirement pattern is different from conventional irrigation forms . it is very useful to research field mulched crops water requirement pattern watering with drip irrigation
膜下滴灌是地膜栽培与普通地表滴灌相结合的产物,在地膜覆盖和滴灌的综合效应下,作物的生长与在常规条件下不同,因此影响作物需水量的一些基本条件都发生了变化,对于膜下滴灌作物需水量和作物系数还需要做进一步研究。 - ( 5 ) the synthetic draft curve was conducted by crop coefficient and relative soil moisture . the correlation in crop coefficient and relative water content takes on uniform trend comparing to the soil water deficient degree . in the whole growth season of cotton , the high correlation coefficient occurred in the period of seeding , which was declined in the period of blooming and flowering , whereas it was raised in the late period of cotton
( 5 )综合作物系数与相对含水率拟合关系表明,作物系数与含水率的相关性与土壤受旱的情况呈现相同的趋势,苗期的相关系数高,而到了蕾期偏低,花铃期更低,到了吐絮期有所升高,整体上表现为水分状况良好,相关性就越高。 - ( 4 ) in 2001 , the average daily et of cotton in the whole growth season is 1 . 75mm / d , the total et is 307 . 48mm , and the average crop coefficient ( kc ) is 0 . 39 under deficient irrigation . in 2002 , the average daily et of cotton in whole growth season is 1 . 94mm , the total et is 337 . 04mm , and the average crop coefficient ( kc ) is 0 . 43 under sufficient irrigation
( 4 ) 2001年胁迫供水情况下,在整个生育期棉花的蒸发蒸腾量为307 . 48mm ,平均日耗水强度为1 . 75mm ,作物系数平均值为0 . 39 ; 2002年充分供水情况下,在整个生育期内棉花的蒸发蒸腾量为337 . 04mm ,平均日耗水强度为1 . 94mm ,作物系数平均值为0 . 43 。
