一体化育苗营养基在西瓜上的应用效果

以西瓜为试材,对北京中农赛世农业科技有限公司研制的一体化育苗营养基进行了应用效果研究。结果表明,采用一体化育苗营养基育苗幼苗期立枯病发病率2.06%,在西瓜后期生长过程中,立枯病和枯萎病发病率仅为1.50%和5.88%,小区果实产量为88.2 kg,坐果率达100%。西瓜幼苗立枯病发病率较营养钵育苗降低4.5个百分点,枯萎病的发病率降低11.72个百分点、产量提高20%以上,同时可促进提前开花4~5 d,坐果率提高6.7个百分点。

Study on the Application Effect of Compressed Integration Substrates in Watermelon
