Investigation On The Paddy Field Cropping System Producing More Than Half-a-ton Of Grain And Ten-thousand Yuan Of Income Per666.7m~2Yearly In The North Of Zhejiang Province

It is significant to investigate and expand the cropping system for producing more than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly for further improving the comprehensive efficiency of major grain producing areas, increasing the farmers’income and meanwhile stabilizing grain production in these areas to ensure safe grain supply.The north of Zhejiang province is an important area of rice production. In recent years, agricultural scientific and technical personnel at local and the main entity of production and management had investigated the paddy field cropping (raising) system to stabilize rice production and increase efficiency. There came forth a batch of systems for producing more than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly. In this paper, summary of main system, key technologies and efficiency for several paddy fields cropping system of producing more than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly which represented by late rice-vegetable in greenhouses paddy field was obtained though field research and comprehensive analysis. Also, the low-lying field raising system for producing more half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly was investigated. In the meantime, current situation, problems and countermeasures for the popularization and application of the paddy field cropping system for producing more than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly in the north of Zhejiang province was analyzed.The main research results were:The main systems for paddy field producing more than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly with late rice-vegetable in greenhouses as the core were:late rice-fresh ginger in greenhouses system, late rice-bottle guard in greenhouses system, late rice-eggplant in greenhouses system, late rice-watermelon in greenhouses system and late rice-pumpkin in greenhouses system. The average vegetables and fruits yield of these five systems can reach2950.8kg, with the production value of13726.8Yuan. The average yield per mu for late ricer reaches577.6kg, with the production value of1450.8Yuan, and the average income per mu of11795Yuan. This achieves the goal of producing more than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly and good social and ecological benefits. The raising systems for producing than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly were:"late rice-turtle and vacant field for ducks" system and late rice-black fungus system. Wherein, the late rice yield per mu of "late rice-turtle and vacant field for ducks" reaches505kg, with the annual income per mu of12138Yuan. The late rice yield per mu of "late rice-black fungus" system reaches540kg, with the annual income per mu of11686Yuan.Main problems inhibiting the popularization and application of paddy field cropping system for producing than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly in the north of Zhejiang province were:poor industrialization and organization, high production input, great labor forces, high market risks, aging personnel, low cultural quality, fast technological updating, difficult to popularize, etc.Hence, It is required to strengthen the guidance, increase the input, cultivate the management organization, tighten the cooperation, scientifically and technologically promote. Establish a model, expand brand and extend industry for further popularizing and applying paddy field cropping system for producing than half-a-ton of grain, ten-thousand yuan of income per666.7m2yearly in the north of Zhejiang provmce.
