| In recent years, the paddy field farming system producing more than half-a-ton of grain and ten-thousand yuan of income per mu yearly has attracted widespread attention among many innovative farming system, because it can stable grain production, ensure national food security, increase farmers’income, and motivate the producers.This paper analyses the development and innovation of the paddy field farming system in Zhejiang province; classifies 40 sets of the paddy field farming system producing more than half-a-ton of grain and ten-thousand yuan of income per mu yearly through the field investigation and data collection; concludes six different types of the paddy field farming system producing more than half-a-ton of grain and ten-thousand yuan of income per mu yearly, namely greenhouse vegetables-rice system, outdoor vegetables-rice system, edible mushrooms-rice system, Chinese herbal medicine-rice system, aquatic products-rice system, animal products-rice system; adopts Cost-benefit analysis method to get the different economic benefits of six types and the highest farming system of each types; summarizes suitable areas, matching technology, cropping arrangement of each types; compares the different economic benefits of six types, edible mushrooms - rice system is the highest economic benefit type of which the production value per mu reaches 44936 Yuan and the average income per mu reaches 23406 Yuan; groups and analyses 40 sets of the paddy field farming system according to value in order to get the farming system of which the average income per mu reaches over 30000 Yuan:rice-black fungus system, greenhouse eggplant-late rice system and stropharia rugosoannulata-single rice system; concludes and analyzes five key technologies of the paddy field farming system producing more than half-a-ton of grain and ten-thousand yuan of income per mu yearly.Through promoting the paddy field farming system producing more than half-a-ton of grain and ten-thousand yuan of income per mu yearly of which economic benefit is prominent, we can solve some issues and problems effectively, such as the shortage of cultivated land resource, the idle cultivated land in winter season, the problem of increasing income by growing grains, the unwillingness of growing grains and so on. In addition, combination of food crops and cash crops, paddy-upland rotation, combination of farming and animal husbandry can improve the farmland environment and soil fertility, reduce plant diseases and insect pests, decrease the usage of chemical fertilizer and pesticides, achieve agriculture sustained development, which has important theoretical value and practical significance. |
