1) whole growth duration of rice
水稻全生育期
1.
To unveil the mechanism of effect of elevated CO_2 concentration and temperature increasing on growth,development and yield formation of rice,many physiological characteristics of rice were measured from the half-open CO_2-temprature gradient system,which treated whole growth duration of rice by different CO_2 concentrations and temperature levels.
为揭示大气中二氧化碳浓度与温度增高对水稻生长发育与产量形成的影响机理,采用半开放式二氧化碳温度梯度系统对水稻全生育期进行梯度处理。
2) rice growth stages
水稻生育期
1.
The results show that the energy flow method gains an advanage over the simple investigation of community number dynamic in reflecting scientifically and accurately the harm level of Sogatella furcifera and the different control levels of Pirata subpiraticus to Sogatella furcifera at different rice growth stages.
以能量为统计标准 ,系统地分析了不同水稻生育期稻田生态系统中水稻 -白背飞虱 (Sogatellafurcif era) -拟水狼蛛 (Piratasubpiraticus)的种群能流动态 。
3) growth of rice
水稻生育
1.
Effect of low temperature and cold injury in growth of rice;
1998年低温冷害对水稻生育的影响
4) irrigation scheduling of rice in the growth period
水稻生育期灌溉制度
1.
With the spread of water-saving irrigation mode for rice, if we continue to use traditional manual method in the day by day calculation of irrigation scheduling of rice in the growth period, the process will be inconvenient and time-consuming, or even lead to a false result.
随着水稻节水灌溉模式的推广,如果水稻生育期灌溉制度逐日推算仍采用以往人工判断、计算的方法,其过程不但繁琐费时,且容易出错。
5) Rice seedling period
水稻育秧期
6) water consumption during the whole growing period
全生育期耗水量

茶树育种生育期鉴定
appraisal of development stage in tea breeding
茶树,种生,期鉴定(appraisal of de-veloPment sta罗in tea breeding)对茶树育种在生长发育过程中经历的时间所表现的性状进行评定。包括年生育期和个体生育期的鉴定,利用生育期的不同形态特征和经济性状,以及对外界环境条件的反应,有目的地加以鉴定。在年生育期内,趁早春可鉴定越冬芽萌发的早晚,对温度的反应,芽叶色泽、大小及茸毛的多少,春梢的生长势和生长量;夏季高温干早季节,可鉴定抗热及耐早性的强弱,芽叶色泽的变化,特别是紫色芽叶的出现,新梢生长量的变化,病虫害的感染程度;冬季可以利用自然条件鉴定茶树对低温的忍耐程度,特别是最低临界温度的反应。年生育期内,还可以鉴定构成产量各因子的表现,各季芽叶的比例,不同时期芽叶质量和内含成分的变化,开花结实习性等。个体生育期鉴定,是指从种子出苗到成龄进入全面采摘阶段,主要是鉴定种子的生活力,幼苗的适应能力、树型、树姿、分枝习性、叶片着生状态、树幅树高的变化、发芽密度等生育特点。单株产量和单位面积内产量增长幅度的变化,也是鉴定茶树个体生育期的重要内容。 (王融初)
