冬季气温较低,光照不足,要夺取西红柿高产,应注意以下五点措施。一、提高定植地温。一般定植西红柿的最低温度应稳定在10℃以上。实践证明,温室采用三层覆盖比普通单层覆盖能提高地温8～10℃,可提前15天定植;起垄高畦比平畦提高地温20℃,再覆盖还可提高地温2℃,且高畦通风透光,浇水不板结。二、改良单干整枝。把西红柿的第一花序的第一侧枝保留下来,等长出一层花亭后,留上面两片叶摘心,主茎按单干整板法进行管理。
Winter temperatures are low, lack of light, to win the high yield tomatoes, should pay attention to the following five measures. First, improve the planting temperature. Generally set the minimum temperature of tomatoes should be stable at 10 ℃ above. Practice has proved that the greenhouse with three layers of coverage than ordinary single-layer coverage can increase the ground temperature 8 ~ 10 ℃, 15 days ahead of schedule can be colonized; ridge Ridge than Pingji to improve the ground temperature 20 ℃, then cover can also increase the ground temperature 2 ℃, Light, water does not form knot. Second, improve single-handed pruning. Leave the first branch of the first inflorescences of tomatoes preserved, wait for a layer of kiosks grow, leave the above two leaves topping, the main stem according to the whole board management.
