【摘要】 对保护地3种西瓜栽培方式下温度、湿度和产量的试验研究结果表明,3种天气状况下三立架二地爬种植方式的温度、湿度有利于西瓜生长发育,是上海地区春季保护地西瓜适宜栽培方式,果实膨大期40℃以上高温对西瓜生长明显不利,较为适宜西瓜生长的田间环境小气候为平均气温27℃,温度变幅15～38℃,相对湿度75％～80％。更多还原

【Abstract】 The data for temperature, relative humidity, and yield of watermelon are gained under three planting modes in plastic shed. The temperature and relative humidity are propitious to the growth of watermelon on three weather states in the planting of three stands and two floors, in Shanghai on springtime. The temperature above 40℃ is not propitious to the growth of watermelon fruit. The suitable average temperature of a day is 27℃ for watermelon, the changes are from 15℃ to 38℃, the suitable relative humidities are from 75% to 80% .更多还原
