二、遮陽降溫工作要做好

一般來說
，甜椒定植後應將棚內白天溫度控製在32℃，夜間控製在18℃。但目前如若不采取遮陽措施，晴天棚內溫度會高達40℃yishang

三、防治根部病害

定植後甜椒死棵主要是由根部病害和澆水過大
、雨水灌棚後出現的漚根導致的。

1.根部病害引起的死棵。導致辣椒死棵的根部病害主要有辣椒疫病、根腐病(疫黴根腐病和腐黴根腐病)、青qing枯ku病bing等deng。根gen部bu病bing害hai是shi辣la椒jiao的de毀hui滅mie性xing病bing害hai，一yi旦dan發fa病bing死si棵ke嚴yan重zhong，很hen難nan控kong製zhi。對dui於yu這zhe些xie病bing害hai，還hai是shi要yao以yi防fang為wei主zhu。建jian議yi菜cai農nong在zai種zhong植zhi前qian每mei畝mu用yong多duo寧ning1公斤+甲基托布津1公斤拌土撒於定植溝內，並與土壤混合均勻，可有效地防治辣椒的根部病害。
