Improvement And Appliction Of Plant Acoustic Frequency Control Device

ABSTRACT:In The 20th century, chemical agriculture has greatly improved crop yields, but along with the excessive use of chemical fertilizers and pesticides, causing soil fertility declination, crop quality decline, environmental pollution, which seriously affects the sustainable development of agriculture. At present, agriculture is in the chemical agriculture to ecological agriculture transition period, and physical agriculture is to realize ecological agriculture, one of the main ways for plant acoustic frequency technology is one of the important contents of physical·agriculture, it is also the core of physical development of agricultural science and technology, can promote plant growth, rise to yield, high quality, disease resistance on the purpose, and will not pollute the environment. In addition, the application of the technique can reduce the dosage of chemical fertilizers and pesticides, production of green food, to promote agricultural sustainable harmony; Improve agricultural added value and competitiveness; Accelerate agricultural modernization, building economical society, etc., which has important significance. Through introducing the Qingdao and Dalian both production acoustic wave generating device test and found many problems, such as portability, ease of operation reliability, and pertinence, this paper, in view of the above questions of plant acoustic frequency control device was improved, which has developed a flexible operation, easy field where no power supply, crop well-pointed advanced automatic control technology of acoustic frequency fueling equipment-Plant resonant grows device of Split and obtain the practical new-type patent certificate (ZL 2005 20075194.8).The device is split chassis design methods, the use of slot connections, easy disassembly. Speaker parts and control part isolated from each other, using high shielding row cable to connect, effectively ensuring the sound effects and amplifier part to come loose hot effect, increase the machine working stability. Relatively independent part of the control box, cooling effect, and is conducive to maintenance, built-in over-temperature protection circuit and protection circuit to ensure stability. Full manual operation and intellectualized operation can be chosen, intellectualized operation on mainly reflects in the following aspects:①automatically feel the sun, to achieve light control power, and regularly work;②feeling wet with automatic functions to achieve line in case of rain power protection;③automatically open when the chassis temperature exceeded the cooling fan, such as over the limit will automatically cut off power supply;④manually set the smart timer switch. In Wuxi Xiajiabian gardening center with the device is trying to acoustic frequency processing, with a contrast test method, through the strawberry growth, quality, yield, disease resistance and mature morphological indexes such as the determination and comparison and analysis, the results indicated that the plant resonant grows machine was used to the growth of strawberries and cucumber have significant positive effects, to improve quality and improve the strawberry sugar content and extend shelf life also have certain effect.
