番茄是大棚主栽蔬菜之一,具有喜水、需水量大、耐旱能力强的特点,且营养生长和生殖生长速度及二者间的协调关系受水分多寡的影响较大,而作为收获产品的果实90%以上是水分。因而在大棚番茄生产中浇水管理是一项重要技术措施。根据多年经验,在大棚番茄浇水管理中,除掌握好常规浇水技术外,还要掌握以下技巧: 一、按不同生育期特点浇水一般情况下,番茄边定植边浇水,定植水后3～5天浇一次缓苗水,一直到第一穗果座住如蛋黄大时再浇一水。结果前期植株较小,叶面蒸腾量小,果数也少,通风量也小,一般7～10天浇水一次,水量要
Tomato is one of the main vegetables in greenhouses, with the characteristics of hi-water, large water requirement and drought tolerance, and the relationship between vegetative and reproductive growth rate and the coordination between the two is more affected by the amount of water, and as a harvest product More than 90% of the fruit is water. Thus in the greenhouse tomato production watering management is an important technical measure. According to many years of experience, in the greenhouse tomato water management, in addition to master the conventional watering technology, but also to master the following skills: First, according to different characteristics of the growing period of watering Under normal circumstances, planting tomato edge watering, planting water 3 ~ 5 days watering Huanmiao water, until the first fruit such as egg yolk seat when a large water. The results of the early plant smaller, smaller leaf transpiration, fewer fruit, ventilation is also small, usually 7 to 10 days watering once, the amount of water to
