Effects of Sprinkler Irrigation on Yield,Quality and Benefit of Chewing Cane in Dry Land
In order to evaluate the effect of chewing cane planting under dry land sprinkler irrigation mode,a comparative experiment was conducted between dry land sprinkler irrigation mode and traditional irrigation mode in Wengyuan County,Guangdong Province in January 2022.In the maturing stage of chewing cane,the yield characters,cane stem appearance characters,internal quality and so on were investigated and determined.The results showed that compared with the traditional irrigation cultivation mode,the indexes of chewing cane planted by sprinkling irrigation cultivation mode in dry land had a very obvious improvement.Compared with traditional irrigated cultivation mode,the plant height,stem diameter,internode length,stem weight and stem yield of chewing cane in dry land under spraying irrigation significantly increased by 7 cm,1.9 mm,0.8 cm,0.2 kg,and 13 t/hm2 respectively.The growth rate of the five indicators reached 2.58%,0.51%,6.25%,1.52%and 9.0%respectively.In addition,the percentage of cane stem flower skin was significantly reduced by 1.25 percentage points,the incidence of tip rot was significantly reduced by 0.42 percentage points,the field hammer was significantly increased by 1.42 percentage points(absolute value),the soluble sucrose was significantly increased by 1 percentage point,and the fiber content was decreased by 0.47 percentage points.Compared with traditional irrigation cultivation mode,the commodity rate of chewing cane in dry land under sprinkler cultivation mode was significantly increased by 2.1 percentage points,the sales price was 0.1 yuan/kg higher,the output value per unit area was significantly increased by 39500 yuan/hm2,and the net output value per unit area was significantly increased by 33900 yuan/hm2.Compared with traditional irrigation,the water saving of chewing cane in dry land was 28.6%.The experiment showed that the chewing cane cultivated in dry land sprinkler irrigation mode not only has good quality,high yield,but also has high commodity rate,which can be widely applied to promote farmers to further improve the yield and quality of chewing cane,so as to obtain higher economic benefits.
