市场前景目前市场上的大棚支架,所用材料无外乎以下几种:竹木、水泥、铁合金、塑钢、钢管等。不难想象,对于广大农业生产者而言,棚架成本低、抗折抗压性能好是其喜好的唯一目标。使用竹木,成本固然低,但其质量让人担忧,而且容易损坏,使用寿命短,还免不了“年年使用年年换”的辛勤之苦。塑钢、钢管等做棚架,可谓之耐用、精美,但其不扉的价格让很多“农友们”望而却步,况且其是热的良导体.受日晒后容易因表面温度高而使其与棚膜接触处开裂,影响大棚保温效果。中国是一个农业大国,尤其在中国迈进 WTO大门之后,农业方面所面临的挑战是不言而喻的,对广大农业生产者来说,如何降低
Market prospects Currently on the market of greenhouses, the material used is nothing less than the following: bamboo, cement, ferroalloy, steel, steel and so on. Not hard to imagine, for the majority of agricultural producers, scaffolding low cost, good bending resistance is the only goal of its preference. The use of bamboo, the cost is low, but its quality is worrying, but also easy to damage, short service life, but also inevitably “every year for every year for ” hard. Steel, steel, etc. scaffolding can be described as durable and beautiful, but its price does not Fei many “farmers ” Moreover, it is a good conductor of heat by the sun is easy to make due to the surface temperature is high and Its contact with the greenhouse membrane cracking, affecting the greenhouse effect. China is a large agricultural country. Especially after China has entered the WTO gate, the challenges facing agriculture are self-evident. For the majority of agricultural producers, how to reduce
