南方温室甜椒提早栽培试验初探

Early cultivation experiment of sweet pepper in greenhouse in South China

选择塔兰多、曼迪、辛普森3个甜椒品种分别于3月25日、5月25日、7月25日播种,研究比较不同提早播种时间对其栽培效益的影响。结果表明,3月25日播种有提早的效果,但不能提高经济效益,后期植株过高,不便于管理;5月25日播种坐果节位过高,平均第4节位才能坐稳果,播种相对过早增加了生产成本;7月25日播种不能起到提早栽培的作用,也不能增加生产效益。对比3个品种的栽培效果,塔兰多甜椒是最适合作提早栽培的品种,各方面性状表现都优于其他两个品种。比较试验结果,南方温室甜椒提早栽培宜6月中下旬播种,不仅有利于甜椒生长和管理,而且可提高栽培效益。

Capsicum frutescens greenhouse cultivation in South China is generally selected to sow in August. T.o investigate the effect of early sowing on the culturing, three varieties Taranto f1, Mandy f1 and Simpson f1 were chosen to sow on March 25, May 25 and July 25, respectively. The results showed that when the seed was sown on March 25, it could grow up earlier. But due to high height of the plant, it is difficult to manage at the late growth stage. The fruit setting node was too high for the plants sown on May 25, and it needed 4 nodes to set fruit. Because of sowing too early, it increased the production costs. Those sown on July 25 could not grow up earlier and show no economic benefits. Comparing the cultivation benefits of the three varieties, Taranto f1 showed better than the other two varieties in every aspects. It is concluded that Capsicum frutescens greenhouse early cultivation should sow in the last ten days in June, which is beneficial to its growth, management and increase the economic benefits.
