The continuous low temperature and low temperature have a great impact on the survival, growth and flowering of strawberry seedlings. Therefore, it is necessary to take appropriate measures to add light to provide a suitable growth environment for strawberries. So how does the strawberry in the greenhouse increase the light in the rainy days? He Zhanli, a strawberry planting management technician at Yangling Modern Agriculture Precision Poverty Alleviation Park, said that he should do the following five aspects. 1, artificial light to add artificial auxiliary lighting, can be used as a light source for incandescent lamps, heat treatment, each ç› 100 watt lamp about 7.5 square meters, heating 5 to 6 hours every afternoon. 2. Keep the water droplets, dust and other debris on the shed film to reduce the light transmittance by about 30%. After 2 days, 10 days, and 15 days of application, the light in the shed will be reduced by 14%, 25%, and 28%, so it should be cleaned frequently to enhance the transparency of the film. 3. Selecting a non-drip film and a drop-free film to add several surfactants to the produced formula, so that water molecules flow into the ground along the film surface without water droplets. The use of a drop-free film shed can increase the light intensity in the shed and increase the temperature of the shed. 4. Reasonably uncover the straw curtain Under the premise of doing the heat preservation work, remove the straw curtain for heat preservation or delay the curtain curtain in advance, which can extend the light time and add light quantity. Generally, the sun is released 0.5 to 1 hour after the sun comes out, and the curtain is covered for half an hour before the sun sets. Especially in the rainy days when the rain stops, it is necessary to properly uncover the curtain to make full use of the scattered light of the sun. 5, do a good job of planting and timely pruning, snoring, tied vines, playing old leaves and other field management, is conducive to ventilation and light in the shed.
