Three points must be paid attention to when buying a greenhouse straw curtain

In winter and spring, the weather is cold, and many old vegetable productions with poor heat insulation have been greatly affected. According to the meteorological department's forecast, this year's autumn and winter season, the air is still cold and belongs to the cold winter, reminding farmers to prepare. Recently, during an interview with the reporters in rural areas, it was discovered that many vegetable farmers are preparing to buy new straw curtains. This is not a negligible thing. Here, you asked industry insiders to talk about how to buy straw curtains.

Hao Master of Yuejia Village on Gucheng Street in Shouguang City engaged in straw processing and trafficking for many years. He proposed the following suggestions to farmers who purchased new straw curtains:

one look. At present, three-metre wide grass curtains are used on automatic roller blinds. Here we will introduce them as an example.

The first is to see how many meridians it has, at least 22 straw curtains are used, and the distance between the two meridians is about 14 centimeters to ensure reliable quality and long service life. Followed by the attention of the outer edges of the two sides of the warp, from the edges of the straw curtain should be maintained at 8-10 cm or so, should not be too far, the purpose is to prevent the wind and other edges will pick up the straw, easy to poke the film, there is insulation loopholes.

Two. The weight of the straw screen determines the ability of the straw curtain to maintain heat and wind resistance to a certain extent. The straw curtain with a width of 3 meters is generally suitable for maintaining a weight of 22-23 pounds per metre. It is also custom-made and thickened. 25 pounds/meter. In other words, the 315m straw should be better than 330 pounds. The vegetable farmer should pay attention when ordering.

Three scrapes. The nylon cords used in the preparation of straw curtains are divided into "raw silk" and "ripened silk" and must be distinguished. Some growers carelessly purchased straw woven straw curtains. They did not use nylon ropes for a year and they were cut off. This caused great losses to vegetable growers. Master Hao taught us a simple method, that is, when purchasing grass curtains, use your fingernails to brush back and forth on the nylon rope. If you pick up the hair, it means that it is raw silk. When buying, pay attention to it.
