Studies on Artificial Controlling Biosphere in Paddy Field and Its New Cropping System Ⅳ. The effect of Integrated Controlling Technology on the Rice Growth and the Paddy Ecosystem
The results showed that, the tillering capacity of rice in the Artificial biosphere in paddy field (ABPE) was slightly lower than that in the traditional rice farming system (CK), but the percentage of panicles forming from tillers increased by 13.4%, the percentage of filled grains increased by 5.5%, the grain yield increased by 5.7%,the N, P, K, Mg content in grains and straws of the ABPF was higher than those of CK Compared with CK the damage of leafhopper, dead heart plants, sheat blight disease and weeds decreased in the ABPF The transplantation method used in the ABPF increased the light transmission ratio in comparison with CK, the fresh azolla biomass uptaken by fish was 31623kg/hm2 in the ABPF during co-existing period of fish with azolla In summer the maximum water temperature in ditch of the ABPF was 3~4℃ lower than air temperature and 0.9~2.6℃ lower than that in field surface The experitmental results proved that the integrated controlling technology of the ABPF promoted the grain yield and quality, and also improved the paddy ecosystem
