| Abstract: |
| Through the field experiment, has researched the influence to soil moisture, yield and qulity components of sugarcane by the water shortage and irrigation in maturing stage, using the sugarcane variety of CYZ03-194 for the experiment material with drought resistant, early mature and high s
ugar content. The results shown that the soil moisture in 0～20 and 20～40 cm was higher than 1.05～1.40 and 1.45～1.58 times respectively, compared the irrigated treatment with non-irrigation. The plant height was kept increasing total in the earth experiment stage, but after 40 days, the plant height continue to increase only by the irrigated treatment. The number of green leaves was declined in whole maturing stage by the non irrigation, but for the irrigated treatment it started to declining after 20 days of irrigation and was higher than 1.6 times to the non-irrigated treatment. The juice ratio was higher than 2%～5% by the irrigated treatment. There was no significant difference between two treatments for the suger content. The fiber content was higher than 6% compared the irrigated treatment with the non-irrigation during 0～20 days, but no significant di
fference was found at the harvest. The sugar content in cane juice was kept increasing trend during 0～20 days, but it was starded to decrease after 20 days by the irrigated treatment which was still higher than 1.75 times to the non-irrigated treatment, however, no significant difference was found between two treatments at harvest. |
