In the autumn harvest season, while people are worrying about where to find a lot of corn stalks, vegetable farmers in Taierzhuang District, Zaozhuang City, Shandong Province, are busy buying corn stalks to prepare for greenhouse vegetable bioreactors.
According to reports, Taierzhuang currently has more than 8,000 vegetable greenhouses. This year, vegetable sheds that use corn stover bioreactor technology to prevent and treat pests and diseases will reach more than 1,500. According to the calculation of 10 acres of corn stalks per shed, this winter can “eat†15,000 acres. The corn stalks produced by cultivated land will reduce pollution and turn waste into treasure.
Taierzhuang produces a lot of corn stalks every year, and some are burned. A large number of them are abandoned in the fields, causing widespread pollution. Through the promotion of new techniques for greenhouse cultivation - straw bioreactors, straw substitutes for chemical fertilizers and plant vaccines have replaced pesticides, which has become an effective way for them to control straw pollution. The prevention and control effect of this technology on diseases and insect pests can reach 45%-95%, 70% of pesticides can be reduced, 60% of chemical fertilizers can be saved, and the time to market for agricultural products can be 15-20 days ahead of schedule, and the harvest period can be extended by 30-40 days. Increasing production by more than 50% can not only digest large amounts of corn straw, but also greatly reduce production costs and increase output value.
