春番茄定植后,气温尚低,浇过“缓苗水”在合墒时及时深中耕一次,然后控水“蹲苗。”在第一层果进入迅速膨大之前,主要是控制浇水和多中耕,在保持土壤有适当水分的前提下,提高土温,这样,可促使番茄根系向纵深发展,扩大根系面积,调节营养生长和生殖生长的关系,适当控制茎叶生长,保证营养积累和加速植株开花座果。“蹲苗”必须根据品种类型、苗龄、土质、降雨等灵活掌握。中、晚熟品种,开花结果较晚,若水分管理不当,则营养生长过旺,对生殖生长抑制较大。因此,在结果前要以
After the spring tomato colonization, the temperature is still low, poured over the “Huanmiao water” in the combined moisture and deep plowing time, and then control the water “Dunmiao.” Before the first layer of fruit into the rapidly expanding, mainly to control watering and multi-cultivating , To maintain the soil with the appropriate moisture under the premise of increasing soil temperature, so that can promote tomato root to the depth of development, expanding the root area, regulating the relationship between vegetative and reproductive growth, proper control of stem and leaf growth, to ensure nutrient accumulation and speed up plant Flowering fruit. “Dunmiao” must be based on the type of species, age, soil, rainfall and other flexible grasp. Medium and late-maturing varieties, flowering later, if the water management properly, the vegetative growth is too vigorous, reproductive growth inhibition. Therefore, before the results to
