石榴裂果是云南蒙自石榴生产中的突出问题 ;从幼果期至成熟果期均会发生裂果。一般果园裂果率为 2 0 %～2 5 % ,严重的果园达 5 0 %～ 70 % ,造成严重经济损失。在掌握其发生规律的基础上 ,采取春初施足农家肥 ,花期至幼果期每间隔 7～ 10d灌水 1次 ;幼果期至果实膨长期适当控水 ,每间隔 10～ 15d灌水 1次 ;临近雨季前 1个月逐增浇灌水频率 ,每间隔 7～ 10d灌水 1次 ,并以少量多次施肥。缓解前期干旱、气候干燥和与后期雨季连续降雨、果园高湿矛盾 ,增强果皮活性、韧性和抗性 ,控制好主要病虫害。裂果率由原来的 2 0 %～ 2 5 %降为现 2 .5 %～ 3.7%。
Pomegranate cracking is a prominent problem in Mengzi pomegranate production in Yunnan Province. Cracking occurs from the young fruit stage to the mature fruit stage. The general orchard cracking rate of 20% to 25%, serious orchards reached 50% to 70%, causing serious economic losses. On the basis of grasping the regularity of its occurrence, taking full application of farmyard manure at the beginning of spring, irrigation once every 7-10 days from florescence to young fruit stage; proper water control from young fruit stage to fruiting stage, irrigation once every 10-15 days ; Adjusted the frequency of irrigation water one month before the rainy season, irrigated once every 7-10 days, and fertilized several times in small amount. Ameliorate the drought in the early stage, the dry climate and continuous rainfall with the latter part of the rainy season, orchards and high humidity contradictions, enhance pericarp activity, toughness and resistance, control of major pests and diseases. Cracking rate from the original 20% to 25% down to now 2.5% ~ 3.7%.
