| 摘 要： | 在传统砂田增温保墒基础上,为进一步提高对土壤的增温效果,提高砂田生产效率,在甘肃皋兰干旱山区的砂田上进行全地膜覆盖(FM)、起垄覆膜(RM)、半地膜覆盖(HM)、和不覆膜(CK)4种栽培模式试验。结果表明:各覆膜处理在5cm、10 cm、15 cm、20 cm、25 cm土层的日地温、西瓜各生育时期平均地温及积温均为全覆膜>起垄覆膜>半覆膜>不覆膜,但随着土层的加深,增温效果逐渐减弱。各覆膜处理西瓜果实比不覆膜处理提前10 d左右成熟,并且西瓜产量和品质均以全覆膜(FM)最优,其产量及可溶性糖含量分别比传统半覆膜提高26%和10%。

| Abstract: | Traditional gravel-mulched field has a certain capacity of water and heat preservation,in order to choose feasible covering techniques in enhancing the production efficiency on it,four different experiments were carried on the gravel and sand mulched field at the arid mountain area in GaoLan,Gansu,such as full plastic film mulching,ridge-forming and plastic film mulching,half flat-mulching and non-mulching.The results indicated that daily temperature,the average temperature and accumulated temperature in di... |
