  Analysis of 5% Prohexadione Calcium Efferevscent Tablets in Rice Production Effectiveness 2010, 0 (4):  0-0.  Abstract + ( 71 )   Abstract: Ring tone by 5% calcium effervescent tablets on the application effect on rice research, results showed that application of 5% rice calcium effervescent tone ring has a certain effect of dwarfing plants and lodging, to increase by grain and improve yield an evident result. Down against the poor, reproductive effects of short duration varieties of better lodging resistance strong, long growth period varieties. Appropriate dose of315-450 g/hm2.

  Support Technology on Integrated Control of Sclerotium rolfsii of Houttuynia cordata 2010, 0 (4):  0-0.  Abstract + ( 51 )   Sclerotium rolfsii of Houttuynia cordata harms very seriously in the planting base and it has become a major obstacle to produce. This paper briefs the incidence period of Sclerotium rolfsii of Houttuynia cordata and its symptoms and presents a complete set of integrated control technology of Sclerotium rolfsii, and gives details of the cultivation and management techniques, breeding stem techniques, soil treatment techniques, soil testing and fertilization techniques, and chemical control techniques. By this set of technology, the disease losses will be reduce to a minimum level so as to achieve high-yield and good quality.

  Utilization and Techniques of Straw 2010, 0 (4):  0-0.  Abstract + ( 66 )   Abstract: Only a small part of the straw are used as animal feed and as fuel each year in China, while a large number of straw are burnt then returned to field. It is a waste of resources, polluting the environment. In this paper discusses utilization technology of straw to promote the rational use of straw resources from animal husbandry point of view.

  Puyang greenhouse grape management techniques and meteorological conditions 2010, 0 (4):  0-0.  Abstract + ( 75 )   Abstract:In order to ensure robust growth of greenhouse grape plants and early access to the results of period,Increase in research income in Puyang fruit of years of greenhouse grape management techniques;Under a greenhouse grape characteristics of each growing season,For soil, temperature, moisture regulation, tree management, pest control and management studies;The results showed that:Grape Cultivation basically can be divided into pre-hibernation management, management of dormancy, germination period of management, and budding to the flowering stage management, and fruit growing season management, maturity, management and post-harvest management of several stages;Grape cultivation and open field cultivation of distinct,Open field cultivation and seasonal year alternating cycle management is basically coincide,The facilities are all cultivated and man-made linked to the regulation.

  The Effects of Gentiana Polysaccharides on the Immune Function in chicken 2010, 0 (4):  0-0.  Abstract + ( 79 )   The experiment was conducted to study the effects of Gentiana Polysaccharides on immune function in chicken.120 Avian broilers were randomly divided into 4groups and fed by oral.A series of tests were carried out such as thymus index, spleen index and histopathology on 7th,14 th,28 th and 42 thafter vaccination.The results indicated that at the dosage of 50 and 100mg/kg, GP could increase thymus index ,spleen index and enhance development of immune organs.The study proved that GP can promote immune function of chicken.

  Effects of Calcium Cyanamide concentration on Peanut's Growth and Yield 2010, 0 (4):  0-0.  Abstract + ( 108 )   [Objective] The research aimed to study the influences of Calcium cyanamide concentration on the peanut's growth and yield and economic benefit.[Method] Through the test in the field,the influences of the different concentration gradient of Calcium cyanamide on peanut's yield and economic benefit were studied in the same environmental condition.[Result] The right amount of Nitrogenous fertilizer could promote peanut's growth,increase the accumulation of the dry material upside the ground and the number of nodule in the stage of the seedling,and enhance the output of the peanut pod.Excessive Nitrogenous fertilizer could reduce the economical coefficient,also could drop the pod output.The safe and effective amount of the new Calcium cyanamide was 75-225 kg/hm2,also the peanut might obtain the most superior agronomic characters indices and got the maximum economic efficiency in the amount of 150 kg/ hm2.[Conclusion] This Calcium cyanamide made by Germany was perfect fertilizer to peanut.

  Study on the leaves growth dynamic of B.napus 2010, 0 (4):  0-0.  Abstract + ( 78 )   From the observation of nine types of rape(B.napus), the growth dynamic state of the leaves is recorded and the corresponding mathematical models are established. I hope that it can provide theorical and practical instruction in B.napus cultivation by them.

  The research of technology to high-yield and low consumpion fertilization program of Typhonium trifoliatum Wang et lo ex H.li et al in shanxi province 2010, 0 (4):  0-0.  Abstract + ( 37 )   Objective:After applicating N,P,K on Typhonium trifoliatum Wang et lo ex H.li et al ,The experiment used the second universal rotary combination design of the program to discuss if the three kinds of fertilizers have a significant effect on yield of this medicinal plant as well as the interaction of the N,P,K effectting on yield.In order to set up the maths model of high-yield and low consumpion Typhonium trifoliatum Wang et lo ex H.li et al fertilization program and provide a theortical basis. Results and conclusion ：The effect of phosphorus is greater than nitrogen fertilizer,nitrogen fertilizer is greater than the potash .If the level of the phosphorus and potassium exceeding the optimal amount of fertilizer will lead to reduction of output. Single applicaion of N,P,K fertilizer,the highest yield of the three kinds of using were :408.7kg/hm2,936.2kg/hm2,302.6kg/hm2;interation effct of phosphorus and potassium has significant value ,undering the level of nitrogen fertilizer for 225 kg/hm2,the amount of phosphorus and potassium fertilizer were :1071 ,330,the largest output reach to 4791.1 kg/hm2, phosphorus and potassium alone to achieve the maximum yield ,respectively 2％,1％;Through the establishment of a data model ,that 95％confidence region ,the three kinds of fertilizer application in the optimal range,urea：289.6～335.9 kg/hm2；over phosphate:957.2～1140.44 kg/hm2；potassium sulfatehm：267.86～323.26 kg/hm2.

  Research on The Sustainable Development Measures of China's New Rural Biogas 2010, 0 (4):  0-0.  Abstract + ( 119 )   Biogas construction is an important development strategy of China's energy content, which have achieved remarkable results. Construction and development status of China's biogas was described, new problems of rural biogas construction due to rapid economic development in rural areas were discussed, measures and advices for sustainale development of rural biogas construction which adapt to the new rural development were made.
