前期生长 meaning in Chinese
early growth
Examples
- Maize plants grow slower in early period because of low temperature , while grow rapidly in the mid and later periods when high temperature and rainy , especially after tasseling the development of grains , corncobs and husks need to accumulate a large amount of dry matter
玉米植株因低温而前期生长缓慢，生育中、后期高温多雨，生长迅速；特别是抽雄后，籽粒、玉米棒和苞皮发育需要积累大量干物质。 - Based on the data getting from field experiment in 2004 , the sas software is used to analyses the growth of plants and root , yield and its composition , water consumption and water use efficiency under different quantity of irrigation water and irrigation time in prophase
摘要依据2004年试验资料，采用sas统计分析软件，研究了在不同灌水量、灌水时间处理下，春小麦生长前期生长状况、干物质积累、最终产量及其组成、春小麦田的耗水量和水分利用率。 - Under the filtration irrigation , the water content could remained a fit range from 14 to 22 percent in the layer of 20 to 70 cm deep , however , the general irrigation could reduce the moisture utilization during the growing period of the maize . ( 4 ) filtration irrigation could well adjust the soil temperature so that the root system made a sufficient absorption of the moisture and mineral nutrinents
从土壤含水量测定分析看，在20 70cm土层，渗灌水分含量一直维持在玉米正常所需的14 22范围内，而漫灌分两次灌水，在每次灌水前一段时间水分含量要下降到14以下，出现水分胁迫，尤其影响到玉米的前期生长。
