一、选择适宜的品种。无支架栽培的西红柿,植株匍匐地面生长,又不摘心,靠其自身茎秆的强度支撑枝叶生长和果实重量。因此,应选择节间短粗,株型紧凑,自封顶型的品种。二、培育壮苗。只有苗子生长健壮,干物质含量高,才能使定植后缓苗时间短,生长快,开花早,多结果。因此,苗床温度应保持23—27℃,夜间保持10—15℃。待7—8片叶子时,即可定植到大田。适宜定植的苗龄为45—55天左右。三、起垄盖膜种植。无支架栽培西红柿要求:少施氮肥,多施
First, choose the right species. Without scaffold cultivated tomatoes, plant creeping ground growth, but also not topping, by its own stem strength to support branch and leaf growth and fruit weight. Therefore, should be selected internodes, plant compact, self-cap type. Second, nurturing strong seedlings. Only seedling growth robust, high dry matter content, in order to make Hibiscus colonization time is short, fast growth, early flowering, and more results. Therefore, seedbed temperature should be maintained at 23-27 ℃, night to maintain 10-15 ℃. To be 7-8 leaves, you can colonize the field. Suitable for planting seedling age of 45-55 days. Third, ridge cover film planting. No bracket cultivation tomatoes Requirements: less nitrogen fertilizer, more facilities
