番茄进入炎热的夏季以后,由于昼夜温差比较小,栽培难度很大。根据几年的实践,初步体会必须掌握以下技术。 1 培育壮苗 壮苗是越夏栽培的基础,标准是:主茎粗0.8～1厘米,紫色,茸毛粗密,节间长2～5厘米;带大花蕾;植株高16～18厘米,叶色黑绿;在10厘米×10厘米的土坨上,根系全部抢满坨。这种苗抗逆性强,缓苗快,根扎得深,是早熟、丰产和安全越夏的基础。为获上述壮苗,应把握5个环节。
Tomato into the hot summer later, due to the temperature difference between day and night is relatively small, cultivation is very difficult. According to several years of practice, the initial experience must master the following technologies. Cultivation of strong seedlings strong seedling is the basis of the summer cultivation, the standard is: the main stem coarse 0.8 to 1 cm, purple, velvet thick, intricate 2 to 5 cm long; with large buds; plant height 16 to 18 cm, leaf color Black and green; in 10 cm × 10 cm of soil Tuo, roots all razed Tuo. This seedlings strong resistance, Huanmiao fast, deep roots, is precocious, high yield and safe summer basis. For these strong seedlings, should grasp the five aspects.
