Abstract:

Scale cultivation in rice is an important symbol of rice intensive production. Questionnaire surveys of 300 samples were used to investigate age distribution, area distribution, cultivation modes and its yield and economic benefit of different rice farmers including ordinary large-scale growers (H1), family farm (H2), and cooperative planting model (H3) in Huoqiu city of Anhui province. The results showed that the age of all farmers was between 40 and 60 years old, but the H3 mode was younger than other two modes. Both the grain yield and economic benefit in H3 mode were higher than that in H1 and H2 modes, respectively. Moreover, average planting area in H3 was apparently higher than that in H1 and H2. And further analysis indicated that older ages and greater cultivated area were the main reason to restrict yield formation, which meaning farmers would be young and intensive and meticulous farming to improve grain yield. The transplanted rice by machine and direct sowing rice had a greater income when compared with transplanted rice by labors. In conclusion, H3 mode incorporating with simple and labor-saving cultivation such as transplanted rice by machine and direct sowing rice could be an effective way to improve the production potential in future.

Key words: Rice, Scale cultivation, Grain yield, Economic benefit
