In order to solve the problems of rice seedling-growing bowl tray made of paddy-straw in the process of application, the improved structural design was made for the early rice seedling-growing bowl tray made of paddy-straw. The paper explored its structural design principle and design process. Compared with the early rice seedling-growing bowl tray made of paddy-straw (CK1), rice bowl carrier of Japanese (CK2) and actual rice production of China (CK3),the paper discussed influence on rice production by field test with rice seedling-growing bowl tray made of paddy-straw after improvement(CK). The results with CK, CK1, CK2 and CK3 as rice seedling carrier respectively showed that: the max normal stress of CK was higher than that of CK1. The seedling with CK and CK1 need not slow growth days, but the seedling with CK2 and CK3 slow growth days when they were transplanted in rice field. Rice-seedling qualities was not significantly different between CK and CK1, but which were better than CK2 and CK3. Cost of production of CK was smaller than that of CK1and CK2, but higher that of CK3. Influence of CK and CK1 on organic matter in soil profile was the same. At the soil level of 0~10cm, 10~20cm and 20~30cm, the organic matter in soil profile of CK were 7.06%, 10.08%, 2.53%, 3.34%, 0.48% and 0.11% higher than that of CK2 and CK3 respectively. Influence of CK and CK1 on dynamics of soil bulk densities was the same. Compared with CK2 and CK3, the CK could enable to reduce dynamics of soil bulk densities. The rice yield of CK was the same to that of CK1. Compared with CK2 and CK3, rice yield of CK was higher than by 10.59% and 13.54% respectively, which benefits to develop others bowl cultivation technology in China.
