在辽宁大连农村的一些蔬菜大棚里,芹菜、西红柿等蔬菜也听上了“音乐”。记者日前在大连一家园艺公司看到,蔬菜大棚里郁郁葱葱,大棚中间放着1台绿色的声波助长仪,不时发出“嗡嗡”的声音。据该公司负责农机和植物保护的技术员介绍,该公司是从2001年开始使用这种仪器的。通过试验,小白菜增产10%-20%,西芹增产30%,商品质量也好,上市时间还提前7-10天。据技术员说,声波助长仪的有效半径为60米,而且距离越近效果越好。它分为8个波段,可以适用于各类植物。用这种仪器,每周开3天,每天3小时,根据叶、果、块茎等不同品种,声音可以自行调节。但是相较使用声波助长仪期间,叶菜的生长效果更明显。声波助长技术是近年来兴起的一项农业高新技术,是目前物理农业科技发展的核心技术之一。大连市农业技术推广站负责人告诉记者,它是通过声波激发蔬菜的活力,不仅可以增强植物的抗病性,而且能够较大幅度地提高作物产量。大连光明山镇佟岭村村民宋明君种植草莓已四五年了。自从去年开始应用声波助长仪后,不仅产量提高了37.7%,而且果实个大、口感好,还提前15天上市,喜得他合不拢嘴。据介绍,大连市农业技术推广站通过试验证明,声波助长技术对蔬菜、果树、花卉、棉麻、粮油作物等均有明显效果。蔬菜、水果普遍早熟1周以上,?
In some vegetable greenhouses in rural Dalian, Liaoning, celery, tomatoes and other vegetables also sound “music.” Recently, a reporter saw a horticultural company in Dalian, lush greenhouses, greenhouses stood in the middle of a green sounder, issued a “buzzing” voice. According to the company’s technicians responsible for agricultural machinery and plant protection, the company started using the instrument in 2001. Through the test, cabbage yield 10% -20%, 30% increase in celery, the quality of the product Ye Hao, time to market also 7-10 days in advance. According to the technician, the effective radius of the sonicator is 60 meters, and the closer the distance, the better. It is divided into 8 bands, can be applied to all kinds of plants. With this instrument, open 3 days a week, 3 hours a day, according to different varieties of leaves, fruits, tubers, the sound can be adjusted. However, compared with the use of sonicator, the growth of leafy vegetables is more obvious. Acoustic booster technology is an agricultural high-tech emerging in recent years and is one of the core technologies for the development of science and technology of physical agriculture. Dalian City Agricultural Technology Extension Station official told reporters that it is through the excitation of vegetable vitality, not only can enhance the plant’s disease resistance, but also to more substantial increase in crop yield. Tongming Village, Guangming Town, Dalian Song Mingjun villagers have grown four or five years. Since the application of the sonicator last year, not only the output has increased by 37.7%, but also the fruit is big and the taste is good. According to reports, Dalian Agricultural Technology Extension Station proved through experiments that sonic technology to vegetables, fruit trees, flowers, cotton, grain and oil crops have obvious effects. Vegetables, fruits generally precocious more than 1 week ,?
