| 1. | Relatively few foresters or tree breeders consider the presence of edaphic ecotypes . 考虑到存在土壤生态型的林学家或树木育种家相当少。
|
| 2. | The plants of natural ecosystems are usually well adapted to the edaphic and climatic character of their region . 自然生态系统的植物,通常十分适应当地的土壤和气候特点。
|
| 3. | Exploration on improving experimental teaching method of the science of edaphic fertilizer 改进土壤肥料学实验教学方法的探索
|
| 4. | Tolerance of chain contact pitch and chain length in the new edaphic and mineral chain ditcher 刀式矿土复合型链条接触节距及链长公差的研究
|
| 5. | A reservoir is built in housetop , have structure of wall of edaphic lay aside , some of alga , fish is put inside , form small - sized ecosystem with assuring water quality fresh 在屋顶建设一个蓄水池,有土壤贮壁结构,里面放些藻类、鱼类,形成小型生态系统以保证水质的新鲜。
|
| 6. | Edaphic factors the physical , chemical , and biological characteristics of the soil that together form an important component of the habitat because of their influence on plant distribution 土壤因子:包括土壤的物理、化学和生物特征,因其对植物分布的影响,共同构成了栖息地的重要成分。
|
| 7. | Head push experiment of mulberry of british the name of a river in shaanxi and henan provinces to stand , have edaphic sample of near 200 years , make the important material that studies climate change and soil now 首推英国洛桑实验站,有将近两百年的土壤样品,现在成为研究气候变化和土壤的重要资料。
|
| 8. | According to relevant data , all sorts of heavy metal are differred as a result of migratory ability , great majority gathers in the earth ' s surface decompose , the edaphic heavy metal that 50 years accumulative total value is less than a country to set is restricted 根据相关资料,各种重金属由于迁移能力差,大多数在地表聚集分解, 50年累计值小于国家规定的土壤重金属限制。
|
| 9. | The rate of contribution of various edaphic physical parameters is different from parameter of soil water infiltration model in different soil texture and husbandry condition , so independent variable factor and priority are different in regression models . the predicted results are satisfactory in correlation husbandry condition 在不同的土壤质地和不同的耕作条件下,土壤的各种物理参数对土壤的水分入渗模型参数影响程度不同,因此引入到回归模型中的自变量因子不同,引入的先后次序不同。
|
| 10. | It does not need much area , not any pollution , not consuming much electricity power , not need much cost . gshp combined floor radiation air - conditioning system possess high seasonal average cop value and great capacity of edaphic depositing heat energy , can ease up supplied water temperature fluctuating with the change of the outdoor air temperature 地源热泵技术联合地板辐射对房间进行冷暖联供的形式,具有地源热泵季节性平均性能系数高、土壤蓄热能力强、能缓解空气源热泵存在的供冷供热能力随环境温度波动大的矛盾等优点。
