音乐声频对大棚蔬菜生长和产量的影响

为了考察音乐声频对大棚蔬菜生长、产量及营养成分等方面的影响,采用自行开发的声频设备,3年中对黄瓜、茄子、番茄、香瓜、辣椒5种大棚蔬菜进行了16次应用试验。结果表明,5种大棚蔬菜平均增高率7.7%～34.3%;生长素含量增加1.3%～14.6%;产量增加4.4%～32.8%,平均增产13.7%;辣椒Vc含量增加5.1%～50%,茄子和番茄的Vc含量分别增加27.7%和26%,黄瓜、茄子、番茄的还原糖含量分别增加7.6%、6.3%和16.5%。研究结果为声频技术在大棚蔬菜生产上的推广应用提供了科学依据。

Effects of music acoustic frequency on greenhouse vegetable

In order to investigate audio frequency influence on the growth,yield and nutrient component of greenhouse vegetable,the music acoustic frequency was applied to the five kinds of greenhouse vegetables including cucumber,aubergine,tomato,cantaloupe and capsicum.The results indicated that five kinds of greenhouse vegetables have different responses to sound wave stress.The greenhouse vegetables’ mean heightening percentage range from 7.7% to 34.3% apart from the minus growth rate of tomato;the increasing rate of auxin content range from 1.3% to 14.6%;the production yield increases from 4.4% to 32.8%,and the average rate of production yield is 13.7%;Vc content of capsicum increases from 5.1% to 50% with the average increase of 22.35%;Vc content of aubergine and tomato increases 27.7% and 26%,respectively;the reducing sugar content of cucumber,aubergine and tomato increases 7.6%,6.3% and 16.5% respectively.The results can provide a scientific basis for plant audio technology applied to greenhouse vegetable production.
