| Chicory, Cichorium intybus, belonging to the Compositae family, is a perennial herbage forage with extensive adaptability, strong disease resistance and good palatability for animals. A new band of chicory, OG02, was studied on growth performance and feed quality in the Yangtse River Basin in order to develop its production potentials and establish rational planting technology in the study.In the study, chicory were sprayed after seeding 2 weeks with CTK in different dilution ratio, 150, 250, 350 times, and water. Different growth traits were explored including number of leaf, leaf size, number of lateral root, root length, root weight and quality parameters including CP, NDF, ADF and OM at this two stages, previous period (after seeding 1.5 months) and following period (after seeding 2 months). The yield of chicory in following period was explored also.The results showed that the most parameters of the chicory leaf and root increased with CTK sprayed. In previous period, spraying 150 times was the best for chicory and better than control group significantly in number of leaf, leaf size, root length and root weight (P<0.05). The positive correlation between the multiple of diluent and treatments were significant (P<0.05) in leaf parameters. So were root parameters, but not significant. In following period spraying 350 times was the best. The negative correlation between the multiple of diluent and treatments were significant (P<0.05) in leaf parameters. So were root parameters, but not significant.The most parameters of chicory quality and yield increased with CTK sprayed. In previous period, spraying 150 times was the best. CP and ADF increased significantly than control group (P<0.05). CP was about 22.29%. DNF was about 20.30%, lower than control group significantly (P<0.05). OM was about 82.26%, lower than control group significantly (P<0.05) too. In following period spraying 350 times did the best. The yield arrived at 3.89 kg/m~2, higher than control group significantly (P<0.05). CP was 22.02% higher than control group and 150 times significantly (P<0.05). OM reached 85.51% significantly lower than control group but significantly higher than other groups significantly. |
