The Research On Ratoon Sugarcane Micro Jet Effects Under Plastic Film

In Test base of Agricultural College, Guangxi University, I used "Yuetang 60" to conduct the research on Ratoon sugarcane micro jet effect under the plastic film,.There are four treatments with randomized block design in the test:no film covered and no sprinkling(A), no film covered and micro jet(B), covered with photolysis film and micro jet(C), covered with ordinary black film and micro jet(D).By means of measuring soil nutritional and water content,the nutritional statu and water content of leaf, the physiological traits and the photosynthetic traits of leaf, and agronomic traits, to study the effect of Ratoon sugarcane drought resistance, yield and process quality, economic efficiency under different treatmeats,exploring a road which is high efficient water-saving and economic science,high yield and glucose. The study results like this:1、Compare the treatmeat covered with film and no film,The soil nutritional status, leaf water content, yield and sugar content of covered with film were higher than no film covered.it indicate the test covered with film can improved drought resistance,aaafertilizer use efficiency, and process quality, increased yield and sugar content.2、Compare the treatmeat micro jet and no sprinkling, The treatment with micro yet is more better the treatment which is no sprinkling in the index of soil and leaf,the sugarcane quality and yield,the drought resistance and so on,it indicate that sprinkling could improve the yield and sugarcane content.3、Compare the treatmeat covered with photolysis film and covered with ordinary black film,the treatment which is covered with black film is more better than what is covered with photolysis film in yield-increasing effect and drought resistance.4、The economic efficiency:treatment D>treatment C>treatment B>treatment A. It indicated that the income of sugarcane growers and the economic benefit of sugarcane planting were improved by micro yet under the film.Summing it up:the best treatment is covered with ordinary black film and micro jet,the second one is covered with photolysis film and micro jet,the third treatment is no film covered and micro jet,the last one is no film covered and no sprinkling.
