| 1. | Nitrogen supply largely controls the growth and fruiting of most plants . 氮的供应密切地关系到绝大多数植物的生长与结果。 |
| 2. | Effect of nitrogen supply on grain filling at different ear position in summer maize 施氮对夏玉米不同部位籽粒灌浆的影响 |
| 3. | Change law of physiological indices and yield for paddy rice under different water and nitrogen supply 不同水肥处理条件下水稻生理指标及产量变化规律 |
| 4. | Effect of combined application of bioorganic manure and inorganic nitrogen fertilizer on soil nitrogen supplying characteristics 秸秆生物有机肥的施用对土壤供氮能力的影响 |
| 5. | Vegetable nitrogen contention and nitrogen leaching in soil were strongly affected by water and nitrogen supply in the experiments 土壤中0 100cm硝态氮积累量随着施氮量的增加而增加,随着灌水量的增加而降低。 |
| 6. | In addition to genetic factors , environmental factors affect the accumulation of ( - glucan ) ( significantly ) as well , for example , increase of nitrogen supply can increase ( - glucan ) content in oat seeds , but the ( details ) for how environmental factors 环境因素对燕麦-葡聚糖含量也有明显影响,氮素供应的增加通常会提高-葡聚糖含量,但是其他环境因子包括磷、钾等矿质元素对燕麦籽粒-葡聚糖合成及积累的影响还不清楚。 |
| 7. | It is a serious issue that water and nitrogen input rates are unreasonable high in vegetable production in china , which may increase nitrate accumulation in vegetable and ground water contamination . in result , these will be harmful to people ' s health . the objectives of this paper which based on column % pot and micro - plot experiments were to compare the effects of different water and nitrogen supply strategies on nitrogen leaching in the soil profile and nitrate accumulation in vegetable as a base for the n and water recommendations in vegetable production 针对蔬菜生产中水氮投入过量造成蔬菜品质下降、地下水硝酸盐含量超标,水、肥资源的浪费以及给人体健康造成的潜在性威胁的实际情况,以油菜和芫荽为研究对象采用模拟土柱、盆栽和田间微区试验相结合方法系统监测了蔬菜生育期内硝酸盐含量的动态变化以及收获后不同土层土壤硝态氮的残留量,研究了水氮对蔬菜硝酸盐累积的影响及对土壤硝态氮残留的效应。 |
