西瓜果实发生裂瓜原因很多,主要和肥水管理有关。归纳起来可以分为田间生长期裂瓜和采收期裂瓜两种。1田间生长期裂瓜原因(1)品种原因。部分薄皮、质脆、小果型的品种容易裂瓜。(2)坐瓜之前土壤干旱时间较长,膨瓜期突然大量浇水或遇大雨造成裂瓜。(3)果实发育初期遇低温发育缓慢,之后迅速膨大而引起裂瓜。(4)膨瓜期大量偏施氮素化肥,瓜皮部扩充缓慢,而内容物膨大迅速而造成裂瓜。采收期裂瓜主要是采收前大量浇水或采收时震动摔打造成裂瓜,部分品种裂瓜也与品种特性有关。
There are many reasons for the occurrence of cracked melon fruit watermelon, mainly related to fertilizer and water management. To sum up can be divided into field growth during the crackle melon and harvest two. 1 field growth period Cracker reasons (1) variety reasons. Part of the thin skin, crisp, small fruit varieties easy to crack melon. (2) before sitting melon soil drought longer, a large number of watermelon melon suddenly or in case of heavy rain caused cracked melon. (3) In the early stage of fruit development, it develops slowly when the hypothermia develops and then rapidly enlarges to cause cracked melon. (4) a large number of partial melon growth period of nitrogen fertilizer, cucumber Ministry of slow expansion, while the rapid expansion of the contents caused by cracked melon. Harvesting cracked melon is mainly a large number of watering before harvesting or harvesting vibration caused by splitting split melons, some varieties of melon also with the variety characteristics.
