Do small greenhouses have high temperature effects on cucumbers?
The early stage of cucumber colonization does not release air and promote seedlings, because there is plenty of water for colonization, and the small arch cover film is covered with water droplets, and it will not roast the seedlings. Implantation 3 to 4 days irrigation 1 seedling water, began to uncover the membrane. When the temperature in the shed increases to 30°C in the daytime, the film is lifted from both ends of the small arch to release the air, and the air temperature in the afternoon shed is closed at 20°C. When the surface soil is dry, select no wind on a sunny day. Uncover the thin film. Catch the sulfuric acid between the cucumber strains at 5 g per plant. Cover the ridge with your hand and combine the loose soil. Insert a 40 cm tall bamboo rake into the cucumber. Spread on bamboo rafts and cover with a thin film. Small arched shed cucumber is not easy to grow bamboo shed within a small space, the temperature changes drastically, early irrigation should be diligent, to maintain adequate water, both anti-high temperature and antifreeze effect. As the outside temperature rises and the nighttime temperature is not lower than 5°C, convective winds are lifted from the sides of the small arches during the daytime. Constantly increase the amount of air release, prolong the release time, and put the night wind. When the outside air temperature has fully complied with the requirements for cucumber fertility, use the morning or evening to withdraw the small arch shed, remove the quail from the bamboo raft, and re-arrange the vines.
