摘要
覆盖地膜后,地表和地表以下20 cm温度分别降低了2.096℃和1.99℃,空气温度提高了1.07℃。显著增加了地面反射光强和“二十世纪”果实的可溶性固形物含量,但对单果重和硬度无显著影响。
Under film mulching treatment,temperature of land surface and 20 cm below land surface respectively dropped by 2.096℃and 1.99℃,air temperature raised by 1.07℃.Light intensity from groud reflection and soluble solids content of‘Nijisseiki’pear fruit were raised significantly,but with no significant effect on fruit hardness and the single fruit weight.
