“This year my cucurbit fruit has a high rate of cultivating melons and has a short growth cycle. No fertilizers are used, and the yield is also improved!†April 6, farmer Cui Yuan'en of Youfang Village, Fangzi Township, Pingyuan County, Shandong Province said that a straw bioreactor is used in greenhouses. The technically grown zucchini grows gratifyingly.
Last year, the straw bioreactor technology was introduced in Fangzi Township, Pingyuan County. With straw as a resource, straw was decomposed and fermented under the influence of special microbial strains, and it was transformed into carbon dioxide, heat, disease-resistant microorganisms, organic matter and minerals required for plant growth. Elements and so on. It is understood that the heat generated during the straw fermentation process can increase the shelf temperature by 3 °C ~ 4 °C, and allow products to be brought to the city for about 20 days, with an increase in yield by more than 20%. The waste residue from decomposition of straw can be used as organic fertilizer, resulting in organic acids. Substances can be sprayed on the leaves and roots of vegetables to increase the immunity of vegetables and prevent diseases and pests. The use of this technology solves the current four problems of carbon dioxide deficiency, low ground temperature, severe disease, and ecological deterioration of the soil in greenhouse vegetable cultivation, so that agricultural products meet the requirements of high yield, high quality and pollution-free.
Wang Changfeng of Hongmiao Village in Fangzi Township is the direct beneficiary of this technology. “In the past, it was believed that more fertilizer was needed to increase production. In fact, this would reduce the disease resistance of the crops, resulting in the consolidation of the soil, increasing input costs, and gradually reducing the benefits.†He said that the use of bio-reactor technology will not only increase the The most important thing is that the amount of pesticides and chemical fertilizers used has been greatly reduced. “Cultivated vegetables have become a hot commodity!†With the same acre of shed vegetables, net income increased by more than 10,000 yuan.
Since the introduction of straw bioreactor technology in Fangzi Township, last year, it has conducted trials and promotion in more than 800 vegetable greenhouses in more than 20 villages. The plant has been planted in strict accordance with the operating procedures of the China Green Cooperative and registered the “Fangxin†vegetable brand. The "rest assured dish" sold to large supermarkets in Beijing, farmers using the technology to increase income more than 800 million, reduce fertilizer and pesticide input more than 160 million.
