The construction of highland granary is an effective way to comply with the important strategic plan of China and allevi- ate the food security problems in Yunnan. In this paper, SWOT (Strengths Weak- nesses Opportunities Threats) analysis was used to analyze the advantages and disadvantages, opportunities and challenges encountered in the construction of Yun- nan plateau granary, and corresponding countermeasures and suggestions were proposed.展开更多

The model theoretically elucidates the relationship between granary storage weight and bottom/side pressure. A new layout of pressure sensors along the inner and outer rings is also proposed to obtain the pressure value. The experimental results indicate that the detection error of the proposed model is significantly lower than 1% with respect to the low-cost detection system, and this effectively satisfies the actual requirement for real-time monitoring of granary storage quantity.展开更多

The results of pheromonitoring let us detect the pest insect’s location at lowest abundance, while visual inspections are not effective, and to determine the data of effective location in granary, proportions traps and pheromone preparative dose. The aggregation pheromone of the synthetic analogue Sitophilus weevils had been carried out, according to the general procedure for preparation of aldol product. Especially for increasing attractiveness of pheromone traps, different types of food baits were tested. The results were observed with using of germinated wheat grains moisten by wheat germ oil. The corn oil was more attractive and effective for attractiveness of whole pest insects in granary. The wheat germ oil and burdock oil was preferred, as food bait, especially for weevils. The special perforated construction of the pheromone trap for pest insects usage has been developed and recommended for storage areas. In a condition of granary, successful testing of pheromone monitoring makes it possible to establish the timing and necessity of quantitative chemical treatments.展开更多
