Research And Application Of The Space Electric Field Control System

Modern agriculture is a scientific and technological achievements and the existing industrial production mode is applied to the socialization of a new type of agriculture on agriculture,with increasing of crop yield and improvement of labor productivity,the environment is polluted,soil fertility is weakened as well,bring the energy crisis to the surface,having a strong impact on the development of the positive policy of the ecological transformation of ecological agriculture in our country.Physical agriculture is a combination of the physics technology which has biological effect and green,pollution-free ecological agriculture,and then regulates development of environment of animal and plant,and ultimately gets high quality,much yield,disease resistance,high efficiency,no pesticide residues of environmental regulation of agriculture.It is a new kind of agricultural production technology which has been developed with the rise of physical agriculture,which is a new kind of non-pollution,low energy consumption,disease prevention and good effect.This article summarizes the advantages and disadvantages of the existing achievements about space electric field at home and abroad,makes every effort to optimize design of a new type of components,simple circuit,long hours of working,less stable and reliable performance of DC high voltage generator.In addition the device is used to supply high voltage power,and tomatoes which grow in greenhouse are selected as experimental object,then putting 50 k V high-voltage electrostatic field into the greenhouse with the application of technology of electric field,according to the contrast experiments,research and analysis four main different effects of comprehensive indicators of growth period of tomato which is loaded the space electric field.Finally,the time period of the best installation space electric field in the whole growth cycle of greenhouse tomato was obtained.Experiment showed that 50 k V space electric field can significantly increase in greenhouse tomato seed germination rate,promote the growth of tomato seedling stage of bud longer,increase the ground part of the fresh weight of tomato seedling period,promote the growth of tomato growth period of plant height,increase tomato results of single fruit weight,increase the output of tomato results period,prolong the harvest time of tomato,improve the quality of tomato.Biostimulation prevention test results for the space electric field in the development of modern agricultural production technology provides the corresponding reference data,for the space electric field technology promotion provides a reference for all over Xinjiang.
