Why soilless cultivation preferred perlite?
It is estimated that about 60 percent in the United States production of perlite used in the construction industry in some form. The remaining 40%, about 14% for soilless cultivation, and the remainder used as filler, filter aid and other purposes. Why preferred perlite soilless culture?
Crop, high yield, good quality
    The soilless cultivation Horticultural combined reasonably regulate environmental conditions such as light, temperature, water, gas, fertilizer, crop growth, and give full play to the potential for crop production. Soilless cultivation of plants faster growth rate compared with soil cultivation, growing strong, for example, 60 days after planting watermelon, soilless cultivation of plant height, leaf number, the relative maximum leaf area were 3.6 times the soil cultivation, 2.2 times and 1.8 times; crop yields can be increased exponentially.
    Soilless cultivation of crops not only high yield, and the product quality is good, clean, fresh, pollution-free. Production of green food, high quality product. Soilless cultivation lettuce, mustard greens, cabbage and other leafy green vegetables production fast growing, low crude fiber content, high vitamin C content; neat appearance of tomato, cucumber, melon and other fruits and vegetables, even coloring, good taste, nutritional value high; carnation flowers, rich flavor, long flowering period, flower number and more.
      Provincial water and fertilizer, and effort, saving labor
     The soilless cultivation to avoid soil irrigation water, nutrient loss and leakage and soil microorganisms absorb fixed, full absorption by crops, and to improve the utilization efficiency. Soilless cultivation of water consumption is only about soil cultivation 1/4 to 1/10, saving water resources, in particular, is extremely important for the arid areas of crops, is one of the effective measures to develop water-saving agriculture ; fertilizer utilization of soil cultivation is only about 50 percent, even lower than the 20% to 30%, more than half of the nutrient loss,
Soilless cultivation, especially in closed nutrient solution cultivation, fertilizer utilization up to 90% or more, even if it is open soilless cultivation system, the loss of the nutrient solution rarely; soilless cultivation of eliminating the need for heavy plowing, cultivating , the entire plot, weeding and other manual labor, and along with computer the soilless cultivation production management facilities and the use of intelligent systems, the progressive realization of the mechanization and automation of operations, greatly reducing the labor intensity, save labor, improve labor productivity, similar to the industrial production.
       3 fewer pests and diseases, avoid continuous cropping obstacles
      Soilless cultivation and horticulture facilities combined, in a relatively closed environment conditions, to some extent, to avoid the invasion of the external environment and soil pathogens and pests on crop, coupled with the robust growth of crops, therefore the incidence of pests and diseases are mild, but also easy to control ; there is no pollution of the soil planting due to the application of organic manure parasite eggs and heavy metals, harmful chemical substances.
      Facilities for soil cultivation, often due to crop even for a large number of soil Middle-earth pass pest, salt accumulation, caused by nutrient imbalances and root exudates autotoxicity problem of called Facilities soil cultivation, soil treatment and disinfection is not only difficult, considerable costs, and lack of efficient drugs, disinfection is difficult to completely, resulting in greenhouse soil cultivated for a few years, the effectiveness of the rapid decline in species until it stops. The soilless culture fundamentally avoid and solve the problem of continuous cropping obstacles per harvested crop after crop, cultivation facilities necessary cleaning and disinfection immediately planting the next crop.
       4 can be greatly expanded agricultural production space
      Soilless cultivation of the crop production to get rid of the constraints of the soil, can greatly expand agricultural production, use of space. Idle barren hills, wasteland beaches, islands, and even the desert, the Gobi Desert can soilless cultivation of crop production, particularly in densely populated cities, with the roof of the veranda, balcony space cultivated crops, while improving the cultivation environment the development of multi-dimensional cultivation in the greenhouse and other horticultural facilities, full use of space, and tap the potential of agricultural production of horticultural facilities.

By China Building Materials Federation perlite branch president, king, president, Professor Liu, Xinyang Teachers College, Xinyang City, Henan of Stone Machinery Manufacturing Co., Ltd. Ma total, Xinyang City in Kay Insulation Materials Co., General Lee, which lasted three months, mainly from expansion furnace equipment and technology transformation, several key aspects of the perlite ore material selection, processing conditions to proceed, experienced laboratory small scale, the factory pilot and trial stages, successfully developed a 4-8mm high intensity horticultural reuse expanded perlite, maximize horticultural perlite water, fertilizer, breathable performance, higher strength nursery mature through a simple screening to achieve the purpose of reuse, greatly planting cost savings, to the vast The garden planting Enterprise has brought considerable economic benefits.
