济丰4号、济丰5号是济南泉星种业集团种苗研究所于1996年选育出的两个中晚熟茄子新品种,2000年5月通过山东省农作物品种审定委员会审定。经多年、多点试验证明,该品种可作春秋露地、秋延迟以及各种类型的保护地栽培。本文介绍春露地栽培技术。一、培育壮苗 (一)浸种催芽播种前5～7天,用50～55℃温水浸种15～20min(分钟),不断搅拌,至水温降至30℃,再浸种12h(小时),将处理好的种子洗净后晾至种子表面无水时放入干净湿纱布中,置于25～30℃条件下催芽,当80%的种子“露白”时即可播种。新收下的种子可用20×10~(-6)～30×10~(-6)的赤霉素处理6h Jifeng 4 and Jifeng 5 are two middle and late maturing eggplant varieties bred in 1996 by Jinan Springs Star Seed Industry Research Institute. In May 2000, they were approved by Shandong Province Crop Variety Approval Committee. After many years, more tests proved that the varieties can be used for spring and autumn, late autumn and various types of protected cultivation. This article describes the spring dew cultivation techniques. First, to cultivate strong seedlings (A) soaking seed germination 5 to 7 days before sowing, soaking with warm water at 50 ~ 55 ℃ 15 ~ 20min (minutes), stirring constantly until the water temperature dropped to 30 ℃, soaking 12h (hours) Good seeds after washing to dry to the surface of the seeds into a clean wet gauze, placed under 25 ~ 30 ℃ under the conditions of germination, when 80% of the seeds “Lu Bai ” can be sown. The newly received seeds can be used 20 × 10 ~ (-6) ~ 30 × 10 ~ (-6) gibberellin treatment 6h
