PC阳光板温室的放风防风技术

  春季是一年四季中温度和湿度都非常适宜的时期,所以对于大棚来说应该将重点放在它的通风方面。阳光板温室大棚通常都是通过放风口的设置实现通风效果的,但风口大小设计有严格的要求,在大风比较多的情况下更是要注意大棚的防风。下面为大家介绍一下阳光板温室大棚的放风防风技巧:
  Spring is a suitable time for temperature and humidity in all seasons of the year, so the ventilation of greenhouse should be emphasized. Sunshine panel greenhouse greenhouse is usually ventilated through the setting of vent, but the size of vent design is strictly required, especially in the case of more gale, attention should be paid to the wind protection of the greenhouse. Following is a brief introduction to the techniques of ventilation and windproof of the solar panel greenhouse greenhouse.

  阳光板温室大棚风口的大小不能完全用某一个数据界定,因为大棚的结构是不同的,降温的时间和速度也随之不同。对于拱度较大的大棚来说,由于热气流很容易沿大棚棚膜的上部排出,所以即使放风口较小,也能取得较好的放风效果。
  The size of the wind outlet of the solar panel greenhouse can not be completely defined by a certain data, because the structure of the greenhouse is different, and the cooling time and speed are also different. For the greenhouse with larger camber, because the hot air is easily discharged along the upper part of the greenhouse film, even if the vent is small, it can achieve better ventilation effect.
  但对于低矮大棚因为拱度较小的缘故,棚内的热气流从放风口排出的速度就慢,棚内的温度就高,所以需要将其顶部放风口开到40厘米宽,才能达到所需的放风效果。,济南阳光板,佛山济南阳光板,济南阳光板温室大棚阳光板温室大棚通风讲究的是多次放小风的原则,目的是将棚内湿气排出,同时补充棚内二氧化碳,为光合作用的顺利进行补充原料。知道大棚内的温度达到设定值的时候,才能将放风口逐步打开,保持棚内温度。

  However, for low-rise greenhouses, because of the smaller camber, the heat flow in the greenhouse from the vent discharges slowly, and the temperature in the shed is high. Therefore, it is necessary to open the top vent to 40 cm wide in order to achieve the desired ventilation effect. Jinan Sunshine Plate, Foshan Jinan Sunshine Plate, Jinan Sunshine Plate Greenhouse Greenhouse Greenhouse Greenhouse Greenhouse ventilation is focused on the principle of multiple light breezes, the purpose is to discharge moisture in the greenhouse, while supplementing the greenhouse carbon dioxide, for the smooth photosynthesis of supplementary raw materials. Only when the temperature in the greenhouse reaches the set value can the vent be gradually opened and the temperature in the greenhouse be maintained.
  由于春季里大风也比较多,所以不能一味的通风,也得注意大棚放风口的防风。首先可以对大棚增加放风绳的密度,并且尽量以摩擦力较大的宽布条作为放风绳,不容易被大风吹松。
  Because there are more Gales in spring, we should not blindly ventilate, but also pay attention to the windproof of the ventilation outlet of the greenhouse. Firstly, the density of the ventilation rope can be increased in the greenhouse, and the wide cloth strip with greater friction can be used as the ventilation rope as far as possible, so it is not easy to be blown loose by the strong wind.
  同时,还要注意在大风天气下加强对大棚的检查,尤其是要防止放风绳松动,风口闭合,这样有可能会对大棚带来不利影响,大棚的零部件有可能因此受到损坏,蔬菜、植物的生长因此而受影响。
  At the same time, we should pay attention to strengthen the inspection of the greenhouse in windy weather, especially to prevent the loosening of the ventilation rope and the closure of the tuyere, which may have adverse effects on the greenhouse. The parts of the greenhouse may be damaged and the growth of vegetables and plants may be affected.
  增加放风绳的密度,而且放风绳较好使用 摩擦力较大的宽布条为好,这种布条在打活结固定棚膜时,摩擦力大,活结不容易被大风吹松。很多菜农图方便使用尼龙绳作为防风绳,因为摩擦力较小,菜农要适当增加尼龙放风绳的密度,并将其固定好,以防风口被风吹合。同时,菜农还要注意在大风天气时随时进行检查,防止放风绳松动,风口闭合。
  Increase the density of the ventilation rope, and the ventilation rope is better to use a wide strip of cloth with greater friction. This kind of cloth has great friction when loosening the knot to fix the shed film, and the loosening knot is not easy to be loosened by the strong wind. Many vegetable farmers use nylon rope as windproof rope conveniently, because the friction is small, vegetable farmers should increase the density of nylon windproof rope appropriately, and fix it well, in order to prevent the air outlet from blowing. At the same time, vegetable farmers should also pay attention to checking at any time in windy weather to prevent loosening of the ventilation rope and closing of the tuyere.
