This year, I just learned to grow tomatoes. I have to change my species of cucumber next year. Due to the fertility of the land, the city's 150,000-mu-acre shed has not been able to grow the same kind of vegetables for many years. Recently, the Municipal Science and Technology Commission's rural science and technology service port introduced a soil improvement technology from abroad. It will be tested in the Xiaotangshan Park this winter. If it succeeds, it will hopefully overcome this problem. “If vegetables are grown in greenhouses, if they are planted continuously, the output in the second year will be reduced by 20% compared with the first year, and the quality, taste and color will be much worse than before. This phenomenon is scientifically called the soil continuous barrier.†Rural Technology Services According to the person in charge in Hong Kong, at present, the greenhouse vegetable in the city of 150,000 mu can not be basically planted for two consecutive years. The total vegetable output of the city is affected. A few days ago, the City Science and Technology Commission introduced a technique for soil improvement in Japan. A layer of permeable plastic cloth was buried in a depth of 20 cm in soil to cultivate highly resistant pathogens against some pests and bacteria, mixed with animal feces and rice bran. Fermented fertilizers processed from the husks are applied to the fields, supplemented with solar energy and steam for soil disinfection. This technology can not only solve the obstacles of continuous cropping, but also avoid the disinfection of chemical fertilizers and pesticides. The vegetables produced are more environmentally friendly.
