以小型西瓜为试材,进行不同的栽培种植方式的比较试验,以期筛选出北京地区春大棚小型西瓜在“两蔓一绳”高密度栽培条件下最佳的栽培种植模式。结果表明:在“两蔓一绳”高密度栽培种植情况下,每667m2定植2 300株采用“1主蔓1侧蔓”单行定植,春大棚小型西瓜的始收期最早为5月26日,坐果率为108.1%,排名第二,单果重最高为1.56kg,畸形果率最低为92%,667m2产量最高为3 878.1kg,并且中心糖含量最高达13.10%,栽培优势明显。
Taking small watermelon as test material, comparative experiments on different cultivation methods were conducted in order to screen out the best planting mode of small watermelon in spring greenhouse in Beijing. The results showed that in the case of “two vine and one rope ” high density planting cultivation, the planting of 2 300 plants per 667m2 was carried out by monoculture of " The fruit setting rate was 108.1% on the 26th, ranking the second. The highest fruit weight was 1.56kg, the lowest malformation rate was 92%, the highest yield was 6678m3 and the highest sugar content was 13.10%. The cultivation advantage was obvious.
