Using five varieties of upland cotton with different oil content as their parents,the genetic effects and genetic parameters of oil contents were analyzed in Hayman’s diallel genetic model with Griffing’s diallel system II. The results showed that oil content followed the “additive-dominant” model, and the additive effect, which accounted for 64.2% of total variance components, had a more important effect on the inheritance of oil content. The regression of cottonseed oil content between Wr and Vr implied that the parent E9 had more dominant genes, while 1011 and 1017 had more recessive genes. Narrow-sense heritability for oil content was as high as 49%, which suggested that to improve the cottonseed oil content, we should use high oil content lines as parents and carry out selection in early generation.

To extend the application of Spanish river carbonatite（SRC）,an agromineral fertilizer,in China,a field and a pot experiment were conducted to verify the effects of SRC on the vegetable growth, yield and soil acidification. The filed experiment was divided into two blocks based on the application of chemical fertilizer （+NPK） or not （-NPK）. Under the condition of -NPK and +NPK,SRC with 1 800 kg/hm²（+SRC1 800）could improve the pepper height and stem diameter,yield and soil pH compared to that of without SRC（-SRC）. Under the condition of +NPK, SRC with 900 kg/hm²（+SRC900）could increase yield and pH,but the improvement of yield was lower than that of +SRC1 800, and the improvement of pH was higher than that of +SRC1 800. The pot experiment tested the effects of different SRC：soil （V/V） mixtures （1∶5,1∶10,1∶20 and 1∶40） on cabbage yield and soil pH. As the amount of SRC in the soil was increased, the yield increased compared to that of without SRC as well,and reached 39.9% in the 1∶5 ration. However, although the pH in the SRC soil were increased, the improvements were not positively related to the increase of the SRC amount in soil. In addition, both the filed and pot experiments showed that the improvement of SRC on soil pH was greater in the early stage than in the late stage of vegetable growth. In conclusion, SRC could improve the vegetable growth and yield, and reduce soil acidification.

In order to study pond polyculture modes with bighead carp Aristichthys nobilis as dominant stocking species, this work was carried out in four ponds with a total area of 7.3 hm² in Jingmen city, Hubei province. Aristichthys nobilis with different body sizes were stocked in ponds at two different time. Meanwhile, the filter-feeding fish, herbivorous fish, omnivorous fish and ferocious carnivorous fish （reptiles） as supplementary fish species were cultured in the ponds primarily cultured with bighead carp. Fishes were fed with a ration of 30% Aristichthys nobilis powder and pellet feed, and simultaneously provided a small amount of biological fertilizer to cultivate natural food resources. Large-scale bighead carp were captured in the middle of the experiment period. The results showed that the highest average yield reached to 12 174 kg/hm², and the lowest average yield was 6 283.5 kg/hm². The production ratio of bighead carp averagely exceeded 50%. In Pond 1^# and 4^#, the cost of powder compound feed was 34 999.5 yuan/hm² and 33 888 yuan/hm², respectively. In Pond 2^# and 3^#, the cost of pellet feed was 50 334 yuan/hm² and 52 614 yuan/hm², respectively. There was a significant difference in feeding costs between two pond culture modes. As far as input-output ratio was concerned, the ratio of 1∶2.06 and 1∶1.85 were found in Pond 1^# and 4#, respectively, which were better than those in Pond 2^# （1∶1.46） and 3^# （1∶1.63）. The feeding competition relationship among the polyculture species（grass carp, crucian carp, blunt-snout bream and bighead carp） was found in Pond 2^# and 3^#. No disease occurred during the culture period, and the water quality was easily controlled. The results showed that Arisththys nobilis culture mode has advantages in cost control, market competition, ecological benefits, and food safety in the bulky freshwater fish industry.

The management planning and optimal allocations of regional water-soil-crop system are studied by meams of multi-objective fuzzy stochastic optimization model. The model takes economic benefits, social benefits, ecological benefits and utilization of labor as the main objectives, seeks the best mode of crop planting and, achieves optimal allocation of water and soil resources. The weight of each objective is determined by the method named fuzzy decision weight that deals with the weight assignment problem well in multi-objective programming. When establishing the optimization model,we also consider the influence of fuzzy factors and stochastic factors on decision-making problems. Therefore, the model is more objective and reasonable, and can make full and effective use of all kinds of limited resources. The case study shows that the model is rigorous in theory, simple in operation and easy to calculate and, it is feasible to apply it to the optimal allocation of water-soil-crop in agricultural system. It can rationally allocate various resources, thereby improving crop yields and economic benefits.

Using the property research paradigm, the unstructured interview method and the observation method were used to investigate G village in the suburb of nanjing. Based on the relationship between farmers and land,the internal relationship between urban expansion and the change of farmers' land values was expounded. The analysis found that the “village complex” of the suburban peasants had faded, and the land has became a helpless means of livelihood. It was also highly substitutable. In the early stage of urban expansion, their land values were diversified and represented as traditional land-based and land-based land separation type （indifferent type）, land security type and land wealth type coexist. This was closely related to the economic awareness, transfer of employment, citizen orientation, face concept, and “farmers” phenomenon brought about by urban expansion. With the intensification of urban expansion, especially the arrival of land acquisition, the land affinity of suburban farmers would be unprecedented. Strengthening, the concept of land values is also relatively convergent, which was reflected in the fact that the property rights and capital awareness of the land are prominent, rather than the return of the traditional rural complex.
