俗话说“万物生长靠太阳”。这就是说,阳光是一切花卉赖以生存、生长和发育的最基本条件,大多数花卉都需要光线,只是不同种类的花卉对光照强度和日照长度的要求不同。 通常人们把阳光分为直射光和散射光。晴天阳光直接照射的光称为“直射光”,阴天的光或庇荫下的光称为“散射光”。光照的强度和时间的长短对花卉影响很大。例如,需要在阳光下生长的月季花、石榴、半支莲、荷花、睡莲等,如果把它们放在荫蔽的环境中,常出现枝条纤细,节间伸长,叶色发黄,还容易受病虫害袭击;喜阴花卉是指原来生长在山野阴坡地带或林下的花卉,在夏季高温季节需要给予不同程度的遮荫,同时,还要 As the saying goes “everything grows by the sun.” This means that the sun is the most basic condition for all flowers to survive, grow and develop. Most flowers require light, but different types of flowers require different light intensity and sunshine length. Usually people divide the sun into direct and scattered light. The direct sunlight in sunny days is called “direct light,” and the cloudy sky or shade is called “scattered light.” The intensity of light and the length of time have a great impact on the flowers. For example, rose flowers, pomegranates, halibut, lotus, water lilies and the like that need to grow in the sun often appear slender branches, internodes elongate, leaf color yellow, and susceptible to being exposed if they are placed in a shaded environment Insect attacks; hi Yin flowers are originally grown in the shady mountain slopes or under the flowers, in the hot season in summer need to give different degrees of shade, but also
