The results show increasing numbers of soil pathogenic microbes with prolonged planting, the main reason for disease occurrence and spread of soil-borne diseases. Hypogenetic plant, lower photosynthetic rates and enzyme activities decrease self-resistance of the cucumber plant to disease. These form the internal-causes of cucumber disease outbreak. Increases in humidity. decreases in temperature and sunlight are the external-causes of cucumber disease outbreak. The longer the succession, the severer is the spread of soil-borne diseases.

结果表明：随种植年限的延长，土壤中病原微生物数量增加，是导致黄瓜土传病害加重的主要原因；黄瓜植株生长发育不良，黄瓜的光合速率及抗性酶活性降低，植株自身抗病性下降，是引起黄瓜病害发生加重的内因；温室内温度降低、湿度提高、光照下降，是导致黄瓜病害发生加重的外部条件。

During thawing period, its soil water changes as season changes (the dynamic rule of soil water has the important relation of the season): from June to July the quality-moisture content of soil water gradually increases and reaches the highest, and from July to August it begins to decreases. The range of the quality-moisture content of the ground litter and humus layer is lower than the illuvial horizon whose quality-moisture content is gradually increasing in this thawing season.

在土壤冻土融化期，草类落叶松林土壤水分存在明显的季节性变化，土壤枯枝落叶层、腐殖质层质量含水量比淀积层质量含水量变化幅度大；6～7月份土壤含水量逐渐增加，达到最高；8月份以后土壤含水量开始降低；土壤淀积层质量含水量保持逐渐上升趋势；坡顶土壤质量含水量明显小于坡底土壤质量含水量。
