The Research On Sugarcane Micro Jet Effects Under Plastic Film

Drought and water shortage has become a major factor restricting the development of sugarcane production in Guangxi areas, in order to solve this problem effectively, develop one new kind sugarcane planting irrigation mode which can save water and money, have high efficiency and high production is particularly necessary. Used "Yuetang60"as tested cultivars to conduct research in effect of micro jet under the film on sugarcane, which the test were carried out in Test base of Agricultural College, Guangxi University, at2013.The test carried out four treatments with randomized block design, treatment A:no films covered and no sprinkling (CK); treatment B:no films covered and micro jet; treatment C: covered with photolysis films and micro jet; treatment D:covered with ordinary black films and micro jet.Soil physical and chemical properties, leaf nutritional status, moisture variation, leaf physiological traits, drought-resistance, agronomic traits photosynthetic characteristics, yield and process quality, economic efficiency and so on were tested for studying the effects of micro jet. The study results like this:1%The soil pH and the bulk density of covered with films were lower than no films covered, while the soil nutrients, porosity, soil moisture, leaf water content, yield and sugar content of covered with films were higher than no films covered. It could be concluded that covered with films could be improved the soil physical structure, improved fertilizer use efficiency, enhanced drought resistance, increased sugarcane quality, yield and sugar content.2,The single stem weight, stalk number, yield, sucrose of micro jet combined with no covered films were higher than CK. It could be concluded that micro-sprinkler could increase the sugarcane yield and sugar content significantly. 3、Covered with black films were better than covered with photolysis films in keeping the soil physical structure, fertilizer use efficiency, water conservation and drought resistance, photosynthesis, plant height, stem diameter, single stalk weight, sucrose and so on. Another, covered with photolysis films came out to be better than covered black films in aspects of cane germination, tillering rate, the effective number of stems, cane yield, etc.4、The economic efficiency of covered with photolysis films combined with micro jet came the first, second by covered with black films combined with micro jet, and finally by CK. It could be concluded that economic efficiency of sugarcane were improved significantly by micro jet under the films, it’s an efficiency sugarcane cultivation technique for high yield, sugar and benefit.
