小苗膜下移栽在春大棚甜瓜生产上的应用初探

Preliminary application of transplanting young oriental melon seedlings under film in greenhouse

为探讨大棚春提早高效甜瓜种植模式,采取小苗膜下移栽技术,以期为甜瓜生产提供指导。结果表明:小苗膜下移栽的定植时间较常规膜上移栽提早11 d,采收时间提早13 d且差异极显著。小苗膜下移栽的甜瓜纵径、横径、单瓜重大于膜上移栽的,其余指标变化与之相反,主要原因是由于没有及时破膜造成膜下温度持续偏高,影响到植株的开花坐果。因此需要加强技术改进,促进植株健康生长,并显著增加效益。

In order to discuss the early and efficient melon planting pattern in greenhouse, the technique of transplanting seedlings under plastic film was used to provide guidance for melon production. The results showed that the transplanting time of seedlings under plastic film was 11 days earlier than that of conventional film transplanting, and the harvesting time was 13 days earlier and the difference was significant. The length, diameter and weight of the melon transplanted under the film were significantly higher than those of the transplanted film. The main reason was that the temperature under film was high so as to affect the plant flowering and fruiting. Therefore, it is necessary to strengthen the technical improvement to promote the healthy growth of the plant and increase the benefit remarkably.
