The cultivation bed direction decreased by about cm, which can effectively prevent the thermal conductivity effect, avoid the decline of soil temperature in winter, and do not affect the light. This kind of greenhouse has relatively high ridge height, large space, easy to work, large buffer to temperature, more heat extraction during the day, good heat preservation at night, and the temperature is not easy to drop. Greenhouse body lighting, heat storage, heat preservation and cold protection are properly handled, which is a very suitable greenhouse type for out-of-season vegetable production. The cost is not high and it is easy to popularize. Has a wind-resistant structure. Like the high-performance greenhouse, the cultivation is varied and the arrangement of stubble is flexible. It can be cultivated in late autumn plus early spring, and one crop of leafy vegetables can be added between two crops in winter. Early spring stubble seedling raising needs to be carried out in a greenhouse with heating equipment), fruit and vegetable production in late winter can also be arranged, and sunshade net can also be used for production in summer.
The evaporation of water in the plastic film prevents the large amount of air humidity in the shed after watering. Select natural materials for moisture absorption, such as rice straw, wheat straw, quicklime and other materials to adsorb water vapor or fog between rows, and select insulation curtain materials with good moisture permeability and moisture absorption, such as non-woven cloth can condense dew on the inner surface, and prevent dew from falling on the plant. Thus reduce the air humidity, ploughing dehumidification by cutting off soil capillaries, can prevent soil capillary water rising to the surface, can avoid a large number of soil moisture evaporation, with the increase of summer temperature. How to properly cool the greenhouse has become an important work of daily management, the following we will introduce the following six measures, 1, external sunshade system. Is to keep the excess sunlight out of the greenhouse. Form shade to protect the crops in the greenhouse.
At present, spray-free plastics have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field. Bioplastics bioplastics are produced by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics are generally synthesized from petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics, due to the use of renewable raw materials with low toxicity and low harm, greatly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic. News:
