Part iPlastic shedDevelopment and construction requirements
The plastic sheds are an easy-to-protected plant-planting facility that covers plastic sheeting materials with no temperature and a single archebrae structure. The role of plastic sheds in agricultural production: the development of plastic shed vegetables, which have played a significant role in optimizing the restructuring of the vegetable industry, increasing farmers ' incomes and easing the supply of vegetables in early spring and late autumn and winter markets, has gradually become a new niche. I. What's a plastic shed? What is its role and characteristics? The plastic shed is characterized by a 4-plastic shed with an incendiary, single-capture surface structure covered by plastic film: it is characterized by ease of construction, ease of planting operations, low investment and extensive application. In my county, the plastic shed is mainly based on early spring, late autumn and late warming, with 30 to 50 days in spring and 20 to 25 days in autumn, and winterization。
The plastic sheds are characterized by ease of construction, ease of operation and low investment, with the application of 52, the current development of the plastic sheds in my county reaching 16,800 acres in 2015 and accounting for 12. 8 per cent of the total area of the vegetables in the county, involving the villages of zhang camp, li zhui, swallow qi and liu guang (town). The survey resulted in an average of 5492 kg of acre production, an average income of $12265 and a per capita income of $247. 9 million from vegetable production in the shed. The construction of 12 demonstration blocks of plastic sheds covering 100 acres and over 50 acres throughout the county has resulted in various patterns of cultivation. Among them, the yang's stalls have developed farming features based on single varieties of tomatoes, eggplants, kale, vegetable flowers, pickles and peppers, watermelons and beans; liu's mouth has developed farming characteristics based on melon thongs; and the swallow collection has developed farming features based on cabbage and belts. Ii. The current status of plastic shed development in my county, in 2015, has reached 6 single peppers and 7 monochromes and 8 monochromatic cucumbers and 9 monochromatic tomatoes and 10 cucumbers and beans, and 11 cabbage or kale or kale

The advantage of developing plastic-castled vegetables (i) is low risk and high success rate. Vegetables have effectively avoided the cold winter season, with significantly reduced production risks and guaranteed income, thus showing good growth throughout the district. (ii) ease management of vegetables in large sheds. The plastic sheds can be ventilated around them, the temperature is easy to control and can always maintain a more appropriate temperature, which will facilitate the growth of vegetables. (iii) the relatively small investment in vegetable sheds. In general, large and medium-sized acres invest between $4,000 and $5,000, and small acres invest only between $2,000 and $3,000, with only one fifth of the solar greenhouse. (iv) multiple layers of coverage can be used, and temperature protection is easy. Plastic sheds offer multi-layer coverage measures to protect against lower temperatures, facilitate the planting of different vegetables at all times in response to market changes and allow for greater space. (v) market marketing advantages are evident. Vegetables can be grown early in the spring, late in the autumn and against the season, with flexible planting arrangements based on supply and demand, balanced marketing, and clear market and price advantages. Iii. The advantages of developing plastic-street vegetables (i) are low-risk and high-success. Big 174, type 1 of plastic shed, bamboo structure: is a traditional type of structure with 6-8 metres across, ridges 1-1. 3 metres high, supported by a large number of poles. The advantage is that costs are low, that operational space is small and that stability is poor. Ii. Zinc-plating steel-structured sheds: this is more used by seeding companies and has the advantage of a steel tube skeleton shed, with the disadvantage that construction is too costly to be replicated in production. 3 the structure of the contours of the magnesium material is large, operational, but costly and has a short useful life. 4 the steel tube skeleton structure shed: is the structural type of the main push in recent years, with a width of 8 m, a ridge of 2. 3 m and no pillar. The advantages are long years of use, space, ease of operation and an environment in which vegetables grow. The disadvantage is that construction costs are relatively high. Iv. Typologies of plastic sheds, and bamboo-structured sheds: traditional structural types, with a width of 618 traditional bamboo-wood-structured sheds 19
The poor condition of the archer facilities in traditional bamboo structures, the small operating space, the narrow field of cultivation, the low stability, safety and resilience to natural disasters have had a negative impact on early spring and fall-lated cultivation。

The new structural plastic shed, which is dominated by steel tube skeleton material, meets the requirements of the “widen width, round arc, long course, large space” standard, with a ridge of 2. 3 metres and a ridge of 8 metres, increasing stability and safety, increasing the area of vegetable cultivation, increasing operational space and further optimizing the vegetable culture environment。
The new structural plastic shed, which is dominated by the materials of the steel skeletons, reached the application of the “blank span 245 and the new steel skeleton plastic sheds”, in 2012, in the zhuang county, promoting the new steel shelf 140 sheds, with a ridge height of 2. 3 metres and a steel tubing stretch of 8 metres, with a vertical height of 1 metre and a distance of 3 metres between the steel racks, with a single iron gate of 0. 8 metres by 1. 2 metres at the same location. The long life, stability and ease of agricultural operations of the new steel tube skeleton sheds, as well as their high temperature, heat storage and ventilation, have reduced the intensity of construction and the process and have been generally well received by farmers.
