测土配方施肥技术对夏季青菜生长的影响研究

Study on the Effect of Formula Fertilization by Soil Testing on Greengrocery in Summer

[目的]为夏季青菜科学施肥提供依据。[方法]以"夏冠"和"抗热605"两个青菜品种为试材,不同用量的4个品牌的有机肥为处理,在扬州市沙头无公害蔬菜生产基地研究了对蔬菜生长和产量的影响。[结果]4种肥料对"夏冠"生长状况的影响程度依次为"壮禾">"勤绿">"金象">"贝莳特",每公顷施用375 kg"壮禾"生产成本最低且产量最高。4种肥料对"抗热605"生长状况的影响依次为"勤绿">"壮禾">"金象">"贝莳特"。"勤绿"按每公顷施用2 250 kg和"壮禾"按每公顷施用750 kg是较好的施肥方式。[结论]"壮禾"生态肥能够明显改善"夏冠"和"抗热605"夏季蔬菜的农艺性状和经济性状,具有很好的示范推广价值。

[Objective]The study aimed to provide base for scientific fertilization to greengrecery in summer, [Method] With Xiaguan and Kangre 605 as tested materials, the treatments with 4 kinds of organic fertilizer brands with different dosage were set up to investigate on the growth and yield of greengrocery in non-polluted vegetable production base in Shantou, Yangzhou city. [Result] The effect of 4 kinds of fertilizers on the growth of Xiaguan were in decreasing order as Zhuanghe 〉 Qinlv 〉 Jinxiang 〉 Beishite, and the production cost was lowest and the greengrecery yield was highest in treatment with Zhuanghe at 375 kg/hm^2.The effect of 4 kinds of fertilizers on the growth of Kangre 605 were in decreasing order as Qiulv 〉 Zhuanghe 〉 Jinxiang 〉 Beishite, and the reatment with Qinlv at 2 250 kg,/hm^2 and Zhuanghe at 750 kg/hm^2 were a better method of fertilizer application. [Conclusion] Zhuanghe organic fertilizer could obviously improve the characters of agronomic and economic of Xiaguan and Kangre 605 and had a high value of popularization and application.
