【摘要】 对五色草的安全越冬进行了不同的保温处理,结果表明:塑料布处理不能使五色草安全越冬;电热温床处理、马粪温床处理、煤火处理、温室处理和暖气室内处理都能使五色草越冬,但对五色草的生长都有一定的影响;如果在温室增添暖气设备,对五色草的安全越冬效果最好.试验表明,五色草在石家庄地区可以忍受10℃的温度,较长时间的10℃以下温度使五色草受到冻害而不能安全越冬.更多还原

【Abstract】 Safe living through the winter of Alternanthera bettzickiana in different heat preservation was treated in our experiment.The result showed that the Alternanthera bettzickiana could not live through the winter with the treatment of plastic cover,but it could live with the treatments such as the electric stove,horsey dejecta,coal stove,greenhouse and indoor central heating.These treatments restricted the Alternanthera bettzickianaAlternanthera bettzickiana grew fine if the central heating was put into the greenhouse.This experiment showed that the Alternanthera bettzickiana could tolerate the temperature 10?℃ in Shijiazhuang.When temperature was below 10?℃ for a long time,Alternanthera bettzickiana could not live through the winter safely because of freeze in jury.更多还原
