果树日灼与裂果,通常发生在干旱的夏季和早秋。现将预防方法介绍如下:一、防日灼。日灼有枝干日灼和果实日灼两种。预防枝干日灼可在枝干上刷涂白剂。其配方为:生石灰5公斤、石硫合剂原液0.5公斤、食盐0.5公斤、动物油0.1公斤、水20公斤。先用少量水化开生石友,然后按比例加入其它配料,充分揽拌即成,于6～9月各涂一次。如不够可继续配用。防果实日灼,一要及时灌水调节果园小气候;二足不要使用硫合剂,必须使用时要严格控制浓度,以波美0.1～0.2度为宜,并要注意适量喷洒,不要让药液在果面凝结为准。二、防裂果。裂果主要是干旱引起的。抗旱不及时,久旱后突然遇雨或灌水是主要诱发因素,因干旱时果皮收缩,雨后果肉大量
Sunburn and cracking of fruit trees usually occur during the arid summer and early autumn. Preventive methods are introduced as follows: First, anti-sunburn.
