番茄是需要光照强度较高的蔬菜。在早春大棚栽培番笳,光照强度远远满足不了它生长发育的需要。因此,春大棚番茄栽培,除了在水、肥、温度等方面下功夫外,充分合理地利用自然光照,是争取早熟高产不可忽视的一项措施。目前大棚冬春蔬菜生产充分利用自然光照的措施很多,如:大棚内挂反光幕,地膜覆盖(也有反光作用),一面坡大棚后墙涂白,合理设计大棚结
Tomatoes are vegetables that require high light intensity. Cultivation in the early spring Fan Fan, light intensity far can not meet the needs of its growth and development. Therefore, the spring greenhouse tomato cultivation, in addition to water, fertilizer, temperature and other efforts, the full and reasonable use of natural light, is to strive for a measure of early maturity and high yield can not be ignored. At present, there are many measures to make full use of the natural light in winter and spring greenhouses, such as: light curtains hanging in the greenhouse, mulching (also with reflective effect), white slope behind the greenhouses, rational design of greenhouses
