长沙市早稻大棚内外温湿变化特征及应用

Changeable Charactersistics and Application of Temperature and Humidity Inside and Outside the Greenhouse of Early Rice Seedling in Changsha

利用2014年3月下旬到4月上旬长沙市金城水乡、二一农庄两个站点的自动观测资料,分析了该地大棚内外温、湿度的变化特征,结果表明,不同地点的大棚内的温、湿度差别不大,温、湿度的波动情况几乎是一致的,这就为不同大棚内早稻秧苗生长发育提供了相近的生长背景,为相近的早稻秧苗素质奠定了气象基础,更为长沙地区早稻统一机插秧奠定了基础。通过长沙市综合智能化监控系统平台,实时对大棚温、湿度进行监控,根据大棚早稻育苗不同阶段对温、湿度的要求分别设立上、下限报警阈值,当出现超过设定阈值的情况时,系统会自动报警。种植大户采取各种措施使棚内温、湿度达到育苗期不同阶段的管理要求,杜绝了水稻育秧中的蒸芽、烧苗、烂种、烂芽、烂秧等现象,为机插水稻的高产奠定了基础。

This paper analyzed changeable characteristics of inside and outside temperature and humidity in rice seedling greenhouse by using automatic observation data of Jincheng Shuixiang and Er-yi Farm. The results showed that the rice seedling greenhouses in different observation sites provided similar growth background with similar temperature and humidity, which could lay the foundation for the unity of rice-transplanted seedling in Changsha. Through the integrated monitoring system platform of Changsha, the temperature and humidity in shed were monitored in real time. Upper and lower limited alarm threshold of temperature and humidity in different stages of rice seedling in greenhouse was set up, the system will automatically alarm when temperature and humidity values were exceeded threshold. Large growers took various measures to meet the management demand of temperature and humidity in different seedling stages, for lowering the occurrence of steamed bud, seedling burnt, rotten seed, rotten bud, rotten seedling, and then promoting high yield of rice.
