crop requirement meaning in English
作物需水量
Examples
- The ability to reduce application rates through use of crn enables producers to avoid the uneconomical practice of applying fertilizer in excess of soil and crop requirements as insurance against potentially large n losses
通过用控释氮肥可以减少施用量，使生产者避免使用超过土壤和作物需要过多的不经济施肥，避免氮素大量损失。 - The experiment indicates the rate is able to meet crop requirement of yield all the year round the research accomplishes the goal of storing solar energy in summertime and utilizing in wintertime , storing in daytime and utilizing in nighttime , storing in sunshine and utilizing in cloudy sky
本文研究的太阳能蓄热系统实现了太阳能夏天贮冬天用、日间贮夜间用、晴天贮阴天用的目的，在不进行人工增温的条件下，能满足作物的冬季生长要求。 - The system is able to efficiently increase temperature and meet crop requirement of temperature for yield . in researching and designing solar energy conserving system in soil for active greenhouse , it adopts instrument of rhlog , tests temperature of six layers to soil temperature , and draws various curve of temperature . it shows the system can efficiency increase soil temperature and reduces change range of temperature in greenhouse in wintertime
在研究和设计主动式温室太阳能地下蓄热系统中，采用温度自记仪器，测试了室温及土壤中六个不同深度的温度数据，绘制了相关温度变化曲线，该曲线表明了主动式温室太阳能地下蓄热系统能有效提高冬季温室土壤的温度，并且减小了日温变化幅度。
