摘要
以"黑美人"西瓜为供试品种,研究不同用量保水剂在西瓜无土栽培中的节水节肥效果,结果表明:在无土栽培中通过适量地施用保水剂可以保证西瓜在缺水缺肥下能够正常生长,同时有一定的增产效果,且可以维持其品质,达到了节水及节肥的效果,其中以85%水肥+0.6%保水剂处理的效果最好,与正常肥水管理相比,不仅能达到节约15%水肥的效果,而且产量还能提高8.08%。另外,在水肥充足条件下,施用保水剂对西瓜不仅没有起到增产的效果,反而有降低产量及品质的负效应。
The experiment was conducted to study the applied effects of water retaining agent on hermeiren watermelon soilless culture under the different level of water retaining agent,water and fertilizer.The results showed that watermelon could grow normally and increase its yield without reducing its quality in the condition of lacking of water and fertilizer when water retaining agent applied properly.Among the treatments,the treatment of 85% water and fertilizer+0.6% water retaining agent was the best one,which saved 15% water and fertilizer and increased 8.08% yield of watermelon.In addition,when the water and fertilizer were enough,the application of water retaining agent could not increase the yield of watermelon but decrease the yield and quality.
