A suitable cultivation mode directly affects the effect of water saving and yield of crops. In order to study the application of the grey correlation model in the research of water saving irrigation, based on water consumption, yield and its components (spike length, ear perimeter, grain number per spike, rows per ear, hundred grain weight, yield) of summer maize, this paper used the improved grey correlation evaluation model to optimize irrigation methods. The test was carried out in North China University of Water Resources and Electric Power located at 34°47′N and 113°46′E and altitude 110.4 m from June 2, 2012 to September 18, 2012. Two kinds of planting modes under furrow irrigation (conventional furrow irrigation and wide ridge and furrow irrigation) were set up, and each mode included 3 kinds of water control lower limit: soil moisture control lower limit of 60% FC (field water holding capacity), 70% FC and 80% FC. The results showed that in a single level comprehensive evaluation and under the same planting mode, the summer maize yield evaluation at 70% FC was highest, the evaluation value of wide ridge and furrow planting was 0.977. Under the same planting mode, the correlation degree of water consumption evaluation index decreased with the increase of the lower limit of the water control, and the water consumption of wide ridge planting with irrigation low limit of 60% FC was the least, which was 349.66 mm, and the evaluation values of water consumption was 1.000. Under the condition of wide ridge planting mode, the water use efficiency of the 3 kinds of water treatments was higher than that of the conventional planting, and water use efficiency of wide ridge planting of 70% FC was the highest and water use efficiency of conventional planting of 80% FC was the lowest, which was 1.97 and 1.41 kg/m3, respectively, and the evaluation value of water use efficiency was 1.000 and 0.333, respectively. With the same water control lower limit, the comprehensive evaluation of yield and water consumption and water use efficiency of wide ridge and furrow irrigation planting mode was better than that of conventional furrow irrigation planting mode, indicating that the wide ridge planting compared to conventional furrow irrigation has certain effect of water saving and yield increasing. In the comprehensive evaluation of first layers, the grey relational degree of wide ridge and furrow irrigation cultivation with irrigation low limit of 70% FC was the biggest (0.852), so the lower irrigation limit for 70% FC was best. The grey relational degree of wide ridge and furrow irrigation cultivation with irrigation low limit of 60% FC was second (0.788) only to 70% FC, and the evaluation results of the weighted grey relational comprehensive evaluation model were consistent with the field test results. Therefore, the selection of the irrigation and planting mode was suggested to be based on local water resources. For the relatively abundant water resources area, wide ridge and furrow irrigation with irrigation low limit of 70%FC was recommended and wide ridge and furrow irrigation cultivation with irrigation low limit of 60% FC was recommended to use for areas with relatively scarce water resources. The research can guide the application of the weighted grey correlation method in the research of water-saving irrigation. [ABSTRACT FROM AUTHOR]

Yield and water consumption are two of important indicators of crop water-saving and high-yield cultivation. In order to verify the feasibility of fuzzy mathematics in evaluation of water consumption characteristics and yield of summer corn, this study an improved fuzzy comprehensive evaluation model was adopted. An experiment from June 2012 to September 2012 was conducted in Henan Key Laboratory of Eater-saving Agriculture Farming Water Test site of North China University of Water Conservancy and Electric Power(34º51′ N, 113º49′ E). We designed two kinds of planting pattern including wide ridge furrow irrigation and conventional furrow irrigation. Meanwhile, relative soil moisture of 60%, 70%, 80% was used for each planting pattern. Crop water consumption of different growth stages of summer maize was determined. Yield and its components were measured. Meanwhile, an improved fuzzy comprehensive evaluation was done after data about yield and water consumption were standardized. The resulted showed that the fuzzy comprehensive evaluation indexes of water consumption respectively were 0.37358, 0.32770, and 0.29872 for wide ridge furrow irrigation lower limits with relative soil moisture of 60%, 70%, and 80%, respectively. The high index indicated lower water consumption. Thus, the water consumption of summer maize for wide ridge furrow irrigation lower limits with relative soil moisture of 60%, 70%, and 80% should be highest for the treatment of irrigation lower limits with relative soil moisture of 80% and lowest for that of 60%. According to the field experiment, the water consumption during the whole growth stage of maize was 349.66, 398.64, and 442.62 mm for wide ridge furrow irrigation lower limits with relative soil moisture of 60%, 70%, and 80%, respectively. The evaluation result was well confirmed by the results of field experiment for the wide ridge furrow irrigation treatment. Similarly, The evaluation results were consistent with that from field experiment for the conventional furrow irrigation treatment. Based on the improved fuzzy evaluation, the relative soil moisture of 70% should have the highest yield with the largest evaluation index of 0.34296 for the wide ridge furrow irrigation treatment, which was supported by the measured yield (7853.39 kg/hm2). Consistent with the evaluation index, the measured yield for the wide ridge furrow irrigation was higher for the relative soil moisture of 80% than the relative soil moisture of 60%. The similar trend was found for the conventional furrow irrigation treatment. In comparison with the other wide ridge furrow irrigation lower limit treatments, the relative soil moisture of 70% was also higher. It suggested that the irrigation limit of the relative soil moisture of 70% was best than the other two irrigation limits for the wide ridge furrow irrigation for both yield and water use efficiency. However, for the conventional furrow irrigation treatment, the irrigation limit of the relative soil moisture of 60% was highest in the water use efficiency, but the irrigation limit of the relative soil moisture of 70% was highest in the yield. Therefore, the irrigation lower limit of the relative soil moisture of 70% was suggested for the wide ridge furrow irrigation and conventional furrow irrigation where water resource was abundant. If water resource was scarce, the irrigation lower limit of the relative soil moisture of 60% was recommended for the conventional furrow irrigation. In sum, the study showed that the improve fuzzy comprehensive evaluation was good for assessment of effects of water saving irrigation. [ABSTRACT FROM AUTHOR]

A one-position comprehensive calibration method based on inertial frame is proposed to suppress the divergence of errors of a strapdown system. The auxiliary navigation information is provided by GPS and celestial navigation system. The coefficients in the error model of traditional comprehensive calibration methods are basically determined by outputs of the INS, thus the computational errors of INS are introduced into the error model. These modelling errors are amended according to the auxiliary navigation information in the proposed method relaxing the constraint to speed and trajectory of the vehicle. Kalman filter is utilized to estimate the gyro constant drifts. The effectiveness of the method is demonstrated by simulation. [ABSTRACT FROM AUTHOR]
