It has great significance to estimate the schedulable capacity of air-conditioning load of public building for participating the power network regulation by forecasting the air-conditioning load accurately. A novel forecast method considering the accumulated temperature effect is proposed in this paper based on Elman neural network. Firstly, the starting and ending date for forecast considering the accumulated temperature effect are determined by providing the five day sliding average thermometer algorithm which is usually adopted in aerology research. Then, the effective accumulated temperature of each day is calculated. Finally, take the effective accumulated temperature, temperature and humidity into consideration, the air-conditioning load of public building in the forecast day is acquired by Elman neural network. Simulated results show that the higher forecast accuracy can be achieved by considering the accumulated temperature effect.

In order to investigate the mature law of Korla fragrant pear with mathematics method, Korla pears in Aksu area be taken as the study object, and the fruit hardness and soluble solid content (SSC) be selected as the research index. The data of the two indices in the mature process are analyzed with Excel, SigmaPlot and Matlab. To draw the change rule of indices and establish the mathematical mode. The research shows that the effective accumulated temperature reaching up 3000°C to 3843°C is main mature stage of the Korla fragrant pear, and there is an accelerating stage in which. The change rule can be precise description by the established mathematical model that can provide reference for fruit maturity modeling.

AbstractAphelinus mali(Haldeman) is an effective natural enemy of woolly apple aphid (WAA),Eriosoma lanigerum(Hausmann). Previous studies have found that, with WAA from Shandong Province (Qingdao) as the host, there are significant differences in various biological characteristics between a Shandong clade and Liaoning clade ofA. mali. The ability of the Shandong clade to control this aphid was significantly higher than that of the Liaoning clade in Shandong Province. In order to determine whether differences were caused by better adaptation of the Shandong parasitoid clade to the population of the host in that province or if it represents a more general fitness of this clade to control the host regardless of location, we compared the same parasitoid clades with hosts from Hebei Province. We found no significant differences in the developmental threshold temperature, effective accumulated temperature, fecundity, longevity, and oviposition period of the two clades, but the duration of host searching of the Shandong clade was significantly longer than that of the Liaoning clade. The instantaneous attack rate, the control ability (a/Th), the search parameter (Q) of the Shandong clade (0.0946, 0.543, 0.0725) ofA. maliwere higher than that of the Liaoning clade (0.0713, 0.382, 0.0381), and therefore, with WAA from Hebei Province as the host, the host adaptability of the Shandong clade ofA. maliwas not worse than that of the Liaoning clade, while the pest control ability of the Shandong clade was still greater than that of the Liaoning clade.

By using the data of climate observation and site geographical information collected from 134 meteorological stations in Sichuan province since 1971, this paper established a calculation model in small grid to calculate the climate resources of facility agriculture including the days, precipitation and effective accumulated temperature in suitable period in Sichuan province. Based on Geographic Information System (GIS), the model was calculated and used to verify residual modification so as to ensure the relative accuracy of calculated values. Meanwhile, the plane and stereoscopic distribution maps of facility agricultural climate resources were made to lay foundation for further division work in Sichuan.

Midge Blight

The ’midge blight’, in which the raspberry cane midge (Resseliella theobaldi) has an important role, is the greatest problem in the raspberry protection. The basis of the chemical protection against raspberry cane midge is the prediction of adult midge emergence. Before the application of sex pheromone traps developed for the investigation of flight pattern, the usage of the accumulated temperature was attempted for the prediction of egg laying, but these temperatures are different in each country. The aim of this paper is to give information on the time of raspberry cane midge emergence and flight pattern by using sex pheromone traps and accumulated temperature calculation.
