| Hunan is the first major grain-producing provinces throughout the country, rice production provinces, the greatest potential for food production is the development of cropping, centralized seedling raising of rice is cropping crack development of hunan food production bottleneck problem. Through the comparative analysis, this paper studies the social and economic benefits of centralized seedling raising of rice, materialized cost, organization, operation mechanism, supporting policies, promote the process and effect, the comprehensive analysis of rice in hunan province focus on the existing problems in the development of rice seedlings, explores the rice seedlings development strategy, the main results were as follows:1. Centralized seedling raising of rice are main ways of water base, wet rice seedlings, dry rice-nursery, plastic tray seedlings (including floppy seedlings seedlings, hard disk) and seedlings;2. Centralized seedling raising of rice effect mainly are cropping area further recovery, promote food science and technology, promote the large-scale production and change mode of production, improve production efficiency and reduce technology risk;3. The rice planting seedlings to education profession, professional cooperative organizations as the breakthrough point, main function is to control rice direct seeding and arable land pastureland, promote the "single change";4. Centralized seedling raising of rice is a government guide, market operation and professional services, standardized management, and promoting the mechanism of the whole system;5. Centralized seedling raising of rice in cultivating seedlings and promoting growth, increasing the basic seedling number have a significant effect;6. Centralized seedling raising of rice exist unreasonable layout is not prominent, the main body structure, key technical problems such as lack of implementation and input mechanism is not perfect;7. The main development strategy mainly centralized seedling raising of rice on the implementation of the layout, in view of the short board of emphasis; On the boards for the main body, focus on the professional seeks to break through; On mechanical nurtures the planting, the standard technology promotes gradually; On boards for equipment, complete facilities to reduce risk; In the mode of production, due to the domain ShiCe promote social service. |
