摘要
对洛阳地区日光温室的光照。温度及湿度的观测表明:12月至翌年元月的旬平均光照度为8.0~22.0KL_A,旬平均气温为11.3~14.2,8时揭苫前的旬平均气温为8.4~10.0C,10cm地温旬平均为12.5~16.9C,旬平均相对湿度在86%以上;晴天条件下一天中室内气温大于20C的时间仅约4小时,全天湿度大都在80%以上。这种环境条件,对于蔬菜生产是不利的,生产上应加强增温、透光和降湿措施。
In solar greenhouse of Luoyang area during December and January , the mean light idensity of ten days is 8. 0-22. 0 KLx,the mean air temperature of ten days is 11. 3-14. 2 C ,the mean air temperature in 8: 00 am of ten days is 8. 4-10. 0 C under the condition of covering with straw mats,the mean earth temperature of ten days 10cm under ground level is 12. 5-16. 8 C ,the mean humidity of ten days is over 86%,there is only 4hours time when air themperature is over 20 C in a sunn day ,the humidity is alwas over 80%in a sunn day. This condition of the solar greenhouse is unfavourable for vegetable plant growth. So addition temperature and light are need for vegetable plant gerowth, and reduction humidity is also favourable to vegetable production during December and January in Luoyang area.
