查询词典 rainfall

The results showed that the temperature had the tendency of increasing in these regions; the rainfall, raining days and relative humidity had no significant changes; the index of K was over 0 in most areas, that is, the possibility of wheat scab occurrence will be increased year by year.

结果表明，冀京津区域气温有增加趋势，有利于小麦赤霉病的发生流行；冀京津区域降雨量、降雨日数、相对湿度等气象因子未表现出明显的变化；大部分地区K指数大于0，即春季小麦赤霉病发生流行的可能性逐年加大。

In rainfall areas, it has no trouble surviving, provided it is in a well-drained area.

在雨量方面，它没有问题尚存，只要它是在一个良好的排水区域。

Rainfall has been fairly well-distributed this year.

今年的雨水很均匀。

Under the plastic-mulched ridge and furrow cultivation, the average soil water content of furrow (12.7%) was significantly higher than that of ridge (9.1%) at the soil depths of 20-100 cm. The locally compacted ridge served as a water flow barrier and a rainfall collection area under locally compacted ridge and furrow cultivation, and the water content of furrow was significantly higher than that of ridge in the same soil depths, which was similar to the characteristic of soil water distribution under plastic-mulched ridge and furrow cultivation. No significant differences were found in soil water content of furrow between locally compacted ridge and furrow cultivation and plastic-mulched ridge and furrow cultivation, with the same efficiency of water collection.

相对于自然垄沟，膜垄的集雨效果明显，沟中土壤平均含水量显著高于垄中，20～100cm土层范围内平均土壤含水量分别为12.7％和9.1％；成垄压实土壤水分在剖面分布状况与盖膜垄沟的水分分布相似，水分向沟内集中，沟中土壤水分含量显著高于同一土层深度处垄中土壤含水量，且与盖膜垄沟处理下沟中土壤水分含量无显著差异，在集水和聚水方面表现出和膜垄的相似性。

Mowing suppressed seedling emergence of tall-growing Stipa krylovii by affecting seed availability due to reproductive parts removal when mown in the previous year, whilst exerted a positive effect on low-growing Cleistogenes squarrossa probably as result of increased light availability and less competitive pressure from adult individuals, because mowing largely lowered the vegetation height and density. 3."U"shaped curve for seedling mortality across the entire growing season was thought to be associated with seasonal changes of air temperature but a small peak from mid-June to early July could probably be attributed to drought due to previous rainfall shortage.

自5月下旬至8月中旬，三种禾草的实生苗密度总体上都呈上升趋势，但刈割和放牧会使克氏针茅的实生苗密度受到抑制，表明前一年的刈割去除部分生殖器官影响形成实生苗的种子来源；刈割和放牧对生长较低矮的糙隐子草实生苗会产生正向效应，对低矮和稀疏植被进行有规律的刈割会增加植物群落内部的光照，减轻实生苗与成年母株的竞争。

Where there was more rainfall, there were more clouds, which reduced the amount of sunlight and heat that reached the land surface, creating cooler daytime temperatures.

那里有更多降雨，有更多的云，其中用量减少阳光和热量，到达地表，造成凉白天温度。

The results showed that: planting two crops in a year under the condition of 640 mm annual mean rainfall in the Loess Plateau conduced to the substantial use of solar and water resources in summer fallow, the biomass yield, economical yield and water use efficiency was improved in different degrees, and the material cycle was enhanced.

结果显示：在黄土高原东南部年降雨量达640 mm左右的旱作农田，发展&一年二熟&种植能较好地利用夏闲期的水热资源，不同程度地提高了全年的生物产量、经济产量、水分利用效率，加强了农田物质循环。

Sulphur content of rainfall water was 3.74 mg/L in the urban, 2.70 mg/L in the suburban and 1.78 mg/L in the countryside.

降水中硫的含量，城市平均为3.74 mg/L，郊区为2.70 mg/L，农村为1.78 mg/L。

Van der Waal says the country has sufficient rainfall for extensive production of sugarcane, which is currently the most efficient crop for ethanol in terms of production cost, being much faster to process and producing more sugar than maize or sorghum.

能源专家说莫桑比克充足的降雨足够甘蔗的大量产出，就生产成本而言，由於甘蔗生产周期短，比玉米和高粱产糖量大，因而它是最有效的作物。
