Abstract: When magnetic fields with the magnetic induction intensity of 0.4T, 0.8T, 1.2T, 1.6T and 2.0T are used to deal with germinating cabbage seeds for 5min, 10min, 15min and 20min separately, the results show that the appropriate combination of field strength and time can activate peroxidase (POD) and polyphenol oxidase(PPO) apparently, and decrease the content of MDA at the same time. Through the downy mildew inoculation tests, the magnetic field effects on the induced-resistance of Chinese cabbage are significantly lower than control, indicating that magnetic field treatment improve the Chinese cabbage downy mildew resistance by removing free radicals in plants, increasing the metabolism of plant’s secondary phenols and reduce the plant tissue within the cytoplasm of the cell membrane permeability and so on.

Abstract: In order to study characteristics of anaerobic co-digestion of corn straw and cabbage, the experiment was performed with corn straw to cabbage (S:C) of 4:1, 6:1 and 10:1 based on total solids (TS) at 35±1°C at initial TS of 8%. The effects of co-digestion on pH, volatile fatty acid (VFA), and biogas yield were examined. Results showed that the S:C of 4:1 was optimal with accumulative biogas yield of 334.53mL/gTS compared with S:C of 6:1 and 10:1 with accumulative biogas yield of 289.31mL/gTS and 311.37 mL/gTS, respectively. This should be attributed to the high VFA concentration achieved by S:C of 4:1.

Abstract: A study was carried to develop model equations for selecting optimum storage parameters for stored cabbages in passive evaporative cooling structures.Three sets of four different types of passive evaporative cooling structures made of two different materials; clay and aluminium were designed and constructed as part of the study. One set consists of four separate cooling chambers. Two cooling chambers were made with aluminium container (cylindrical and square shapes) and the other two were made of clay container (cylindrical and square). These four containers were separately inserted inside a bigger clay pot inter-spaced with clay soil of 5 cm (to form tin-in-pot, pot-in-pot, tin-in-wall and wall-in wall) with the outside structure wrapped with jute sack. The other two sets followed the same pattern with interspacing of 7 cm and 10 cm, respectively. The set with 7 cm clearance served as the control in which the interspace soil and the jute sacks were constantly wetted at intervals of between 2 to 4 hours depending on the rate of evaporation with water at room temperature. The other two sets (5 cm and 10 cm interspaced soil) were constantly wetted with salt solution (sodium chloride) at the same interval to keep the soil in moist condition. Freshly harvested matured cabbages were used for the experiments and the temperature and relative humidity were monitored daily. The vitamin A, vitamin E, bacterial and fungal counts of this produce were determined at intervals of three days for a period of 21 days. Mathematical models (using essential regression software package) were developed to predict the vitamin A and vitamin E contents of the stored produce at various conditions considered in the study. Further analysis by optimization process revealed optimum storage conditions for the stored produce using essential regression software package. Optimum values of 8.86IU and 4.03 mg/ml in storage were obtained for vitamin A and vitamin E contents, respectively for stored cabbages at various conditions.

Abstract: The residual levels and dissipation rates of metaldehyde in cabbage and soil at three main cabbage-growing areas in china were determined by A simple,rapid and sensitive analytical method with liquid chromatography with TripleQuad mass spectrometry (LC–MS–MS). The limit of quantification (LOQ) was 0.0005,0.0005mg/kg for soil and cabbage, respectively. The mean half-life of metaldehyde was 5.84 days in cabbage and 3.17 days in soil. The final residues in cabbage and soil detected at 7 days after the last spreading were considerably all below 1mg/kg (the MRL of China). Low residues in cabbage and soil suggest that this pesticide may be safe to use under the recommended dosage.

Abstract: The pre-cooling device was built and the columnar cabbage was taken as the study object in this paper. The heat and mass transfer mathematical models for the cylindrical shape vegetable were built and the experimental method was introduced to prove them. The comparison and analysis, under the certain vacuum degree of the vacuum chamber, was done between the simulation and the experiment. And the differences of the vacuum degree in the chamber, the temperature change of the cabbage, the relative humidity in the chamber and the cabbage mass loss, in the experiment and the simulation, were all recorded. The reason of the parameters variance and existent deference was also analyzed in this paper. The mathematical models and the result were useful for the study on the cylindrical vegetable vacuum pre-cooling technology.

Abstract: Effects of drying time, drying temperature, plasticizer and thickening agents on the mechanical properties of cabbage-based edible films were investigated. Films plasticized with glycerol exhibited significantly effect on mechanical properties. Drying time and temperature could show significantly effect on moisture content of the films. Thus, the optimal technology stuff ratio (CMC-Na :gelatine :glycerol :cabbage slurry) was 0.6 :0.3 :3 :96.1. The drying temperature was 55°C, and the drying time was 6.5hrs. The achieved cabbage-based edible films had original flavor, color and suitable strength.

Abstract: In the test, we adopted the method of potted plant cultivation to research that how the organic fertilizer influences on the growth of plants in the soil as regards to different concentration of lead pollution and analyze the transport of lead in soil and plants system. In each group, The root tolerance index (RTI) and transport factor (TF) of plant were analyzed. The results showed that the root of the plant had great effect on the lead pollution. After its root contacted lead, most of the lead were kept in root, rather than moving. The quantity of lead of plant including ground and underground were measured. The results showed that the quantity of lead in underground was too much higher than the quantity on the ground.
