Greenhouse cold winter skills 1, foliar spraying: low winter temperatures in the greenhouse lighting weak crop root absorption capacity decreased, we can to foliar spray of potassium dihydrogen phosphate solution, increase the sugar content and hardness leaf, improve plant cold hardiness, ease the degree of damage. Or the use of rice vinegar and sugar and mix superphosphate, dubbed 100-300 times, spraying the leaf surface. 2, cultivating cold insulation: winter greenhouse ground compaction, daytime heat into the plow layer is restricted, less soil heat storage, combined with large cracks and deep soil compaction, poor aggregate structure, Qianban Ye volatile heat, low temperatures late at night, could easily lead to frost damage. Shallow cultivator can break the ground cracks, so that heat can take control groundwater transpiration, but also take advantage of ventilation when cold insulation seedling. 3, covering warming: Keep sealing films greenhouse, shed set up in the shed or in a small shed increase to cover insulation, night cover film, covering the grass thatch on film; mulching in the greenhouse, greenhouse construction Dandong greenhouse, greenhouse bottom outside surrounded by grass thatch and plastic film as aprons, cold air can reduce the bottom; at the same time pay attention to plug the gap around to minimize the gap cooling.
