In order to investigate the application effect of a new defoliation ripening agent Xinsaili, on medium early-maturing cotton （Gossypium spp） varieties in the cotton-planting area of Poyang Lake, the field experiment wascarried out with Ganmianza No.1 as test material. The results showed that the defoliation and ripening treatment had very good defoliation effect. After 15 days of spraying, the defoliation rate could reach above 95.0%, and when sprayed for 25 days, it could reach 100%. The ripening effect was thiophenone 750 g+ethephon 2 700 mL/hm² was the best treatment, followed by 2 700 mL/hm² Xinsaili treatment. The defoliation ripening treatment could significantly increase the yield of prawn cotton, including thiophenone 750 g+ethephon 2 700 mL/hm² treatment was the highest, followed by 2 700 mL/hm² Xinsaili treatment. Each defoliation ripening treatment had no significant effect on single boll weight, single boll housing weight, clothing score and fiber quality. There was no effect on the germination of cotton boll seed with a bell period of more than 50 d during spraying. In summary, under the same climate and geographical conditions in Poyang Lake planting cotton area, the same application techniques as those of early-maturing varieties are applied to the mid-early maturity varieties, and the defoliation ripening effect is ideal, indicating that the appropriate dose of Xinsaili（1 800~2 700 mL/hm²） can be used for defoliation and ripening of medium early-maturing varieties.

Analysis the effects of temperature on apple flowering time by using apple phenology and meteorological data of Luochuan county and Ansai district of Yan’an city for many years to improve the level of weather forecast of apple flowering period. The results show that the apple initial flowering day in Yan’an is in mid-to-late April, and the difference between North and South is about 10 days. The initial flowering day of apple can vary by 15 days between years in the same area. The date and the accumulated temperature to steadily passed 3 ℃,10 ℃ are similar in Luochuan county and Ansai district, which are suitable for analyzing apple flowering period. Within 48 hours, the minimum temperature decrease by more than 8 ℃, and the weather with minimum temperature ≤4 ℃ is determined to be a severe cooling process. A cooling weather could delay the flowering period by 3~6 d. The weather process is identified as flower forcing high temperature process, when the temperatures averaging above 15 ℃ for more than 10 days, higher than the average annual temperature of 4 ℃ or above. High temperatures can prompt apples to bloom 5 days earlier. In order to predict the flowering period of apple by accumulated temperature, we should pay attention to the accumulation process of stable passage through 3 ℃, 10 ℃ date and accumulated temperature, and severe cooling and high temperature weather, which have obvious influence on flowering period.

It is of great significance to effectively identify the poverty-stricken areas and appreciate the mechanism of their evolution based on remote sensing to strengthen the coordination between poverty alleviation and rural revitalization. In this paper, a method of constructing multidimensional poverty index by integrating nighttime imagery with the correlation coefficient and analytic hierarchy process is proposed. And at the same time, the accuracy of the model is tested. With the spatial analysis technology of geographic information system （GIS） and the characteristics of temporal continuity of nighttime light imagery, this paper makes a detailed analysis of the dynamic development of poverty-stricken counties from the perspective of spatial-temporal evolution. The results demonstrate that from 2003 to 2013, the proportion of the poverty-stricken counties in Sichuan dropped from 46.45% to 28.42%. The variation coefficient illustrates a decreasing trend, which proves that the poverty gap within Sichuan province is slowly narrowing. In the spatial distribution evolution map from 2003 to 2013, most districts and counties in Ganzi, Aba and Liangshan autonomous prefecture are in long-term multidimensional poverty. The increase of multidimensional poverty index is not miraculous in the extreme poverty and extremely affluent counties, but the increase is miraculous in the middle counties. In the hot spot analysis, the hot spot area and the cold spots gradually show an east-west trend. The results of this study can provide a prospective basis for the accurate formulation of poverty alleviation policies in areas with complicated local alienated poverty situation.

Based on the survey of rice-crayfish integrated systems from seven town in Jianghan plain in 2018， the current status and its problems of the development in rice-crayfish integrated systems were investigated. The production inputs， economic benefits， fertilizer and the disease and insect pests were analyzed and suggestions for the future development of rice-crayfish integrated systems were provided. Results show that the number of area and organizations are growing rapidly in recent years， especially in nearly three years. The expenses of land circulation， purchasing parental crayfish and formula feed are the mainly part of the total cost in the system， while the expenses of renting reaping machine， digging ditches and employment consist the secondary part of the total cost. Compared with the rice monoculture， the rice-crayfish integrated systems had lower application amount of nitrogen fertilizer and phosphate fertilizer， while the application amount of potash fertilizer and compound fertilizer remained basically unchanged. Although the occurrence rate of insect pests decreased in rice-crayfish integrated systems compared with the rice monoculture， the occurrence rate of disease in rice increased oppositely. This investigation revealed the key problems in the development of the rice-crayfish integrated system， and provided scientific basis for the sustainable development of this system.
