一、采取“三留”、“三疏”整枝:大棚番茄为提高前期产量,在整枝中要掌握:1.第一花序下第一侧枝留1—2片叶摘心,其余侧枝全部疏除;2.第一花序留2—3果,疏除过多花果;3.第二花序以上每穗花留3—5果,疏去过多花果,3—4花序以上留2片叶摘心。 二、实行“三水”“三肥”管理:番茄生育期中需肥量大,也比较耐肥,除重施基肥外,还应根据生长发育要求结合浇水追施速效性肥料。大棚番茄常实行“三水”、“三肥”管理:1.浇缓苗水追提苗肥,
First, to take the “three stay”, “three sparse” pruning: To enhance the pre-production greenhouse tomatoes, pruning to grasp: 1. The first inflorescence to stay 1-2 leaves topping, the remaining side branches all sparse; 2. The first inflorescence to stay 2-3 fruit, sparse excessive fruit; 3 second inflorescence to stay 3-5 flowers per spike, sparse to spend too much fruit, 3-4 inflorescence leave 2 leaves topping. Second, the implementation of the “Sanshui” “three fat” management: tomato fertility in the growing period, but also more resistant to fertilizer, in addition to re-base fertilizer, but also according to the requirements of growth and development combined with water quickly topdressing fertilizer. Greenhouse tomatoes are often implemented “Sanshui”, “three fat” management: 1. Mianmiao water chasing Miaofei,
