At the same time, the paper introduced each function module of aquaculture for the intelligent monitoring system and formulate control standard according to the aquatic products in different growth stages of demand, through the real-time monitoring of aquaculture environment, measured the standard parameter setting of parameters and the system automatically adjusts the aquaculture environment comparison. The test results show that the temperature error is in the range of 0.5 ℃, dissolved oxygen amount of error is in the range of 0.3mg/L, the error of pH value is within 0.3, system data transmission correct rate is more than 98%.展开更多

Therefore, we must reconstruct our national food security strategy with a cornerstone of an integrated productivity, the focus control of market regulation forces and the protection of sovereignty. By analyzing the status of integrated productivity, market regulation force and sovereign control, this essay proposes that we should change the concept from ＂ food production＂ to ＂foOd management＂, design the two systems of the interest coordination and the special safeguard, effectively improve the enthusiasm of the government＇ s undertaking work in grain-producing areas and farmers＇ farming work, firmly grasp the two initiatives of acquisition and processing of grain and operating inputs, and actively apply recommendations of the two regulators： food exports, processing and conversion.展开更多

文摘The recent outstanding issues,＂ puzzles of farmers, anxiety oflocal government and helplessness ofcentral government,＂ facing Chinese grain security, depend on the lack of national food security strategy. Therefore, we must reconstruct our national food security strategy with a cornerstone of an integrated productivity, the focus control of market regulation forces and the protection of sovereignty. By analyzing the status of integrated productivity, market regulation force and sovereign control, this essay proposes that we should change the concept from ＂ food production＂ to ＂foOd management＂, design the two systems of the interest coordination and the special safeguard, effectively improve the enthusiasm of the government＇ s undertaking work in grain-producing areas and farmers＇ farming work, firmly grasp the two initiatives of acquisition and processing of grain and operating inputs, and actively apply recommendations of the two regulators： food exports, processing and conversion.
