降水

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。

The deep cultivation-root cutting in before winter stage would increasethe weight and ratio of root system in middle and lower layer,the resultswould decrease the root redundancy.

冬前深耘断根可增加中、下层根系的重量和比率，降低根系生长冗余性，控制最高总茎数，提高成穗数及成穗率，使籽粒产量中来自花后光合器官输送的比例增加，从而使产量提高，因而在旱地高产麦田应推广冬前深耘断根。6研究了降水量对旱地高产小麦耗水规律及产量的影响，拔节前降水多且占比重高，土壤供水量及占比重少，拔节后降水量减少且占比重低，土壤供水量及占比重高，利于在旱地高产麦田形成高产。

It is concluded that the outburst of glacier-lake is attributed to abnormality of climatic conditions. The wet and cold conditions are favorable for the accumulation of glacier, and debris flow can take place easily when it gets wet-warm and dry-warm, or air temperature abruptly raises 0.6~l.2℃.

分析了气温和降水对冰湖溃决和及其所形成的泥石流的影响，认为冰湖的溃决大部分是由于异常气候条件造成的，冷湿的气候有利于冰川的积累，当气候转为湿热和干热或气温突然升高。0.6~1.2℃时最易引起冰湖溃决泥石流。
