中文摘要	研究了新疆半干旱地区辣椒疫霉病的发生流行与种植密度、灌水频率的关系.结果表明:栽培密度和高秆作物套种可明显控制病害的发生程度,随着密度不断增加,病害初始发生时间呈现逐渐向后推移的趋势;与高秆作物套种可明显抑制辣椒疫霉病的发生,约可推迟疫霉病初发期10 d,发病率下降70%以上.高频率的灌水可控制病害的发生,而低频率的灌水有利于促进病害的传播和发生.该地区辣椒疫霉病的防治应采取:育苗前对苗床进行药剂处理,合理密植或者套种高秆作物,配以合理的灌水可有效的控制其发生流行.
英文摘要	Occurrence of the capsicum Phytophthora in the semiarid region of Xinjiang has some pecu-liarity of the oasisi-irrigation agriculture, the severity of the capsicum Phytophthora has close relationship with planting density, irrigating frequence and ground-surface temperature. Highly planting density and interplanting high-stalk crops such as corn can control the occurrence of the disease, because they can keep the ground-surface temperature much lower. Water plays some important roles in the occurrence severity of the disease. First ,high frequence of irrigation keeps the ground-surface temperature to be lower, that is unfavorable to burth of the spore ascus and swarm spore. Second , water promotes the spread of the spore ascus and swarm spore as a carrier of the germ. . The measures controlling the disease should be adopted, first the soil of the seedbed should be dealt with fungicides before growing seedlings, and then ridging cap-scium , rationally planting density or interplanting high-stalk crops in the growing field, followed by ratio-nal frequence of irrigating. The fungicides can be used to irrigate the root so capscium as a kind of auxiliary measure , and used on the initial stage of the disease occurrence.
