Abstract
The rice seedlings used for mechanically-transplanting were raised by covering with two-layer plastic film in the test.Taking covering with common plastic film or nothing as the check,the effect of mulching with four different thicknesses of non-woven fabric on the quality of rice seedling was studied.The results showed as follows:(1) Different treatments had significant influence on leaf age,seedling height and leaf length(P0.05),while had little influence on leaf area per plant and stem-base diameter(P0.05).There were no significant differences in the morphological indexes of rice seedling among four treatments of covering with non-woven fabric.(2) The growth of seedling root system in treatment Ⅰ(covering with 15 g/m2 non-woven fabric) and treatment Ⅱ(covering with 20 g/m2 non-woven fabric) was better than that in other treatments,which produced more roots,developed longer root,and had higher root-shoot ratio.(3) The chlorophyll content in N-1functional leaves was decreased significantly as the thickness of covered non-woven fabric increased.The dry matter of seedling in the treatment of covering with non-woven fabric or plastic film was significantly less than that in the treatment of covering with nothing,but the proportion of dry matter in functional organ leaf,stem and root was still 30~35∶45~55∶15~20.(4) The final seedling rates in treatment Ⅰ,treatment Ⅱ and treatment Ⅲ(covering with 25 g/m2 non-woven fabric) were higher than those in other treatments.So the optimal specification of non-woven fabric for raising of mechanically-transplanted rice seedling was 20 g/m2.
