大棚内外温湿度对枇杷春梢和果实生长发育的影响

摘要

The 12-year-old Dawuxing loquat trees taken as the materials were studied in this experiment. The experiment studied the relationship between the air temperature and relative humidity of plastics greenhouse and the growth and development of loquat. The results showed that: (I) The air temperature inside the greenhouse increased 0.25 -3.90℃ than that in open field. The air relative humidity inside greenhouse increased 0.69 to 31.66 percentage points than that in open field. Affected by temperature and humidity, the growth and development of loquat fruit and spring shoot phenology were at least 7 d earlier than that in the open field. (ii) There were significantly positive correlation between the air temperature and the growth and development of loquat fruit and spring shoots, and there were significantly negative correlation between the relative humidity inside the greenhouse and the growth and development of loquat fruit and spring shoot The correlation between the growth and development of loquat fruit and spring shoot and the relative humidity in open field were not significant.%本试验以12年生大五星枇杷为材料,研究了大棚内外空气温湿度变化规律与枇杷春梢、果实生长发育规律及其相关性.结果表明:①大棚栽培能使气温较露地提高0.25～3.90℃,使空气相对湿度较露地提高0.69～31.66个百分点,并使枇杷果实与春梢生长发育物侯期比露地提早至少7d以上；②大棚内气温与枇杷果实、春梢生长发育存在极显著正相关,空气相对湿度与枇杷果实、春梢生长发育存在极显著负相关；③露地气温与枇杷果实生长发育及春梢仲长生长存在极显著正相关,空气相对湿度与枇杷果实、春梢生长发育间相关性不显著.
