1. Qinggou Drainage: In order to remove the snow in time, it is best to remove the snow from both sides of the shed and sweep it from the membrane to prevent the snow from melting into the shed. 2, to improve lighting: during the day to be as soon as possible to uncover the curtain, shade nets and other coverings, increase lighting, but pay attention to the method of uncovering the cover when covering the cover, not a one-time full exposure to prevent the snow from turning fine, Too much light caused by severe crop water loss caused acute flash seedlings to wither. 3, fertilizer management: thawing after the snow, the plants resumed growth, the weather was clear at noon, depending on the growth of vegetables can be followed by application of faecal water to promote growth. 4. Warmer and warmer: Temporary warming measures are adopted to reasonably regulate the temperature in the greenhouse. Warming and freezing can be used to buckle small sheds in large greenhouses, arching with thin bamboo arches, covering with double-layer membranes, or covering shading nets on small arched ceiling membranes. The conditions are also suitable for hanging under large greenhouse membranes. Two-layer film 5. Repair of greenhouses: Regardless of whether the large or medium-sized sheds in the snowstorm are collapsed or half-fallen or not, we must seize the time to repair and reinforce the skeletons and sheds, add wood support in the sheds, reinforce the pillars in the shed, and reinforce the lamination line. The bottom membrane of the greenhouse should be soiled with mud, membrane membrane holes should be filled with tape, and small holes with micro-films can be dampened with water.
Laser distance measure is a very convenient
tool for various types of applications in industries, construction and house decoration.
Laser distance meter is a very useful device which gives accurate measurement
of distance, area and volume especially in large areas such as rooms,
apartments, buildings, real estates, factories, warehouses, infrastructures, gardens,
roads, and many other applications requiring accurate results for distance ,
area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the laser rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
