Greenhouse back slats instead of straw sturdy and durable
The back slope of a greenhouse is generally composed of five parts. The bottom is a steel wire and the top is a thin film. Then a layer of straw curtains is covered with a layer of film and then covered with soil. Grass curtains mainly play the role of soil in the back slope, because the grass curtains are soft. Once damp, it will easily lead to the collapse of the back slope after rot, which will cause great harm.
It is understood that if the vegetable farmers use the new straw to fix the slope, the service life is still long and can reach 67 years. However, considering the cost, the vegetable growers are generally not willing to use new ones, and often use old straw that was replaced on the original shed. The service life of such a straw curtain is also four or five years.
Is there something that can replace the straw? Recently, when the reporter interviewed Dongsha Town in Qingzhou City, he happened to encounter several greenhouses on the upper slope. The reporter observed that they are no longer using straw curtains on the backslope, but they are see-sawboards.
The seesaw is a machine made of scorpions. It is harder and has a better soil setting effect. According to the used farmers, the sampan board is strong and durable, and has strong anti-aging ability. The service life is more than 10 years and it can also reduce the use of steel wire. It is understood that the original use of straw screen, the 1.2 m back slope has to set about 15 wires, and use the seesaw, because of its good soil support effect, can reduce the number of wire, generally with about 10 on the line, and the use of cost Just like old straw blinds.
