| 6. | 2 . in rhizosphere culture experiment , re applications with appropriate dose in three weeks significantly increased the biomass ( dry matter ) of rape and rice , and the effects of re on the rape was better than the rice , but they decreased or became little significant in eight weeks 根际培养条件下,第三周低浓度稀土处理显著提高油菜和水稻的生物量(以干物重计) ,对油菜的作用效果优于水稻,第八周作用趋缓或不明显。 |
| 7. | In vivo activity of prothoracicostatic peptide in the silkworm , bombyx mori for the sake of further research on the function of ptsp to ecdysteroidogenesis in vivo , based on the culture experiments in vitro , prothoracicostatic peptide was injected into the b . mori hemolymph in differ 为研究材料,研究棉铃虫ptsp的cma序列以及与家蚕ptsp的cma序列的关系,这将对昆虫亲缘关系、系统进化发育关系的研究、害虫的生物防治提供参正且考。 |
| 8. | First , the dynamics of soil properties in different period during a year from the long - term no - tillage and ridge culture experiment field are researched in order to get the general dynamic properties of organic matter , chemical substances , microbe , ph and eh in soil 首先通过对自然免耕定位试验的有机残体的分解与转化的动态特征研究,得出有机残体分解转化过程中的有机质、养分、微生物及出和eh的动态特征,总结出有机残体分解与微生物关系的一般规律。 |
| 9. | Our aim is to provide reference data for the mechanism of the effects of ree on crops and the safety evaluation of re used in agriculture . 1 . in soil culture experiment , re applications with appropriate dose in dry condition increased the contents of soil available n , whose no - effect value were 505mg / kg at eighth week , whereas higher levels of re had negative effects , re applications with both appropriate and higher dose in inundated condition reduced the contents of soil nh / - n and hydrolysable n . re treatment concentrations showed significant positive correlation with the contents of soil exchangeable re . and significant negative correlation with the contents of soil available p and soil ph value . there was no significant effects of re on soil exchangeable cations , but applications of re increased the contents of soil water soluble cations , especially that of ca2 * and mg2 + 两种培养条件下,稀土处理浓度与土壤交换态稀土含量成正比,与有效磷含量、土壤ph成反比,对土壤交换态盐基离子含量无显著影响,但通过置换作用增加了水溶态离子,尤其是ca ~ ( 2 + ) 、 mg ~ ( 2 + )离子的含量;第二周稀土处理增加交换态zn含量,对交换态fe有降低作用,旱培条件下增加交换态mn含量,淹水条件下对其有降低作用;第八周稀土处理均提高交换态fe 、 mn 、 zn含量,其机制主要与稀土降低土壤ph有关。 |
| 10. | A survey of literature shows that little study has been done on uptake of pollutants by plants from the polygonaceae , and that the reports about their physiological and biochemical characteristics under heavy metal stress were sporadically seen . a batch of sand culture and soil culture experiments were carried out to investigate heavy metal and radiocesium uptak e and accumulation by rumex acetosa linn , polygonum microcephalum d . don , and rumex hastatus d . don widely distributed on copper mining areas , and their physiological and biochemical characteristics under cu zn stress , as well their potentials in application to phytoremediation 本论文以广泛生长于铜矿区的蓼科植物酸模、小头蓼和戟叶酸模为试验材料,运用砂培、土培等方法,研究它们对重金属( cu 、 zn )以及放射性核素( ~ ( 134 ) cs )的吸收和积累特性以及cu 、 zn胁迫条件下它们的生理生化特征,初步探讨它们在无机污染物污染土壤植物修复中的应用潜力。 |
