干旱

And rainfall data,twenty-three sites of hydrology and telemeters in KaHai drainage area in 2005 were analyzed and calculated to find that the new Co-Kriging method was feasible and the result was more perfect,the method was feasible in the west of Tianshan Mountain.

地处干旱半干旱地区的新疆河流大多数是山区性河流，水文站点较稀疏，这种问题更为突出。因此，有必要采用一些合适的空间插值方法来研究降雨量的空间分布。传统的降水量

New sea 21 are varieties which can save water effeciently,so they have advantage in arid and semi-arid region.

新海21是节水型品种，能够较充分的利用有限的灌溉水，在干旱半干旱地区具有强大的优势。

Because China's western area is vast and arid region accounted for almost half the land area, so the Chinese are not familiar with 1:00 to drought.

因为中国的西部地区幅员辽阔，是干旱地区占了几乎一半的土地面积，因此中国不与1时00熟悉的干旱。

Yellow river valley is typical arid and semiarid region in China.

黄河流域是我国典型的干旱和半干旱地区，流域缺水、支流水质污染和污水灌溉面积的增加对环境、农业生产和农产品安全造成了潜在的威胁。

North China ; Arid and semi-arid region ; Wind erosion.

中国北方；干旱半干旱地区；土壤风蚀

Starting from the correlation between precipitation and crop water requirement in Chaoyang County,the profit and loss of natural precipitation and the drought situations in Chaoyang Area were discussed by using the balance formula of crop water requirement and drought index method.

从朝阳县降水量与作物需水量之间的关系出发，应用作物水量平衡公式和干旱指数法，探讨朝阳地区自然降水的盈亏与干旱情况。

Stomatal restriction was the main factor for the P's decrease in the leaves of both alfalfas under light drought stress, while the non-stomatal restriction was the main factor for the P's decrease in the leaves of these alfalfas under medium and severe drought stresses.

2轻度干旱胁迫下气孔限制是两种紫花苜蓿P降低的主要因素，中度和重度干旱胁迫下非气孔限制是P降低的主要因素。

But 4 varieties had different responses to high N after re-watering, root biomasses of drought sensitive varieties increased, drought resistance varieties did not.

干旱敏感型品种抵御干旱能力差，复水后恢复生长的能力较差。此外，增施氮、钾肥的植株绝对生物量没有明显的增加，但植株的生长速率、干物质增长速率均高于低氮、低钾的处理和对照。

These bryophytes, in this sense, have to tolerate great heat and drought.

在干旱和半干旱地区，影响苔藓植物分布的环境因子包括降水、p H值、Ca CO3 含量、植被盖度、有机质含量以及土壤质地等，其中起重要作用的是降水。

With the water stress, stoma open rate declined, and the stoma of Kidney bean was more susceptible than the Capsicums.

气孔开放率随着土壤含水量的降低而降低，且菜豆气孔对干旱逆境敏感性大于辣椒；可溶性糖和脯氨酸含量均表现为上升的趋势，说明干旱胁迫可以诱导菜豆和辣椒两种蔬菜积累渗透调节物质，提高自身保水能力。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
