Eight treatments including N, P, K, NP, NK, NPK, PK and controls were done for studying its absorbing efficiency of soil nutrition. At tillering stage, the coefficient of absorbing and utilizing of N, P, and K from soil and fertilizer were analyzed according to M.K. Kaeomobk抯 formula and the contents of crude protein and fat were also measured. The yields of fresh crop, hay and seed were measured at ripening stage. For N absorbing coefficient of Ph. arundinacea from soil (Kn%), the composition PK treatment is best (12.36%) and K treatment is worse, while for N absorbing coefficient from fertilizer (Ky%), all the treatments are higher than control but the composition NPK treatment presented the highest (14.78%). For the absorbing coefficient of P from soil (Kn%), composition NK treatment is highest (19.30%), but K treatment was lower than control, while for that of P from fertilizer (Ky%), all the treatment were higher than control but the composition NP treatment showed the highest (19.52%). As to K absorbing coefficient from soil (Kn%), NP treatment is the best (19.2%) and single P treatment is worst, while for that (Ky%) of K from fertilizer the composition NPK treatment was best (28.44%). As concerns treatments for the outputs of fresh and dry crop, the composition NP treatment was best and all the treatment were higher than control. The composition NK treatment produced highest yield of seed and highest content of crude protein as compared to other treatments. For content of crude fat, the compositions NK and N treatments are best. The experiment indicates that application of fertilizer at proper proportions could increase the yield of Ph. Arundinacea and raise the utilizing efficiency of nourishment element from soil and fertilizer.展开更多

[Method] The corn millet data reported by China Industrial and Technological Re- search System of Millet in 2011 were analyzed by descriptive statistical analysis of EXCEL. [Result] The results show that 17 678.57 kg/ha of farm manure, 155.77 kg/ha of urea, 259.5 kg/ha of compound fertilizer, 203.13 kg/ha of phosphate fertilizer and 75 kg/ha of potash fertilizer were used in China; the national mechanization degree of broomcorn millet production is lower than 30% in all; the average income of broomcorn millet production is 10 503.33 yuan/ha, and the VCR is 2.64; most broomcorn millet producing areas are affected by mild pests and diseases, very few are affected by mild and moderate pests and diseases, and the impact of natural disasters is the lightest. [~onclusien] Currently fertilizer utilization for broomcorn millet is proper but the mechanization level and planting benefit are low, natural disasters, pests and diseases are not severe; finally the authors proposed some suggestions on the fertilizer utilization, mechanization production, benefit increasing, disaster warning, disease and insect controlling and government policy-making for broomcorn millet production.展开更多

Under the constraints of land shortage, how to allocate the finite land resources to the multiple land users in China considering various political, environmental, ecological and economic conditions have become research topics with great significance. In this study, an interval fuzzy national-scale land-use model(IFNLM) was developed for optimizing land systems of China. IFNLM is based on an integration of existing interval linear programming(ILP), and fuzzy flexible programming(FFP) techniques. IFNLM allows uncertainties expressed as discrete interval values and fuzzy sets to be incorporated within a general optimization framework. It can also facilitate national-scale land-use planning under various environmental, ecological, social conditions within a multi-period and multi-option context. Then, IFNLM was applied to a real case study of land-use planning in China. The satisfaction degree of environmental constraints is between 0.69 and 0.97, the system benefit will between 198.25 × 1012 USD and 229.67 × 1012 USD. The results indicated that the hybrid model can help generate desired policies for land-use allocation with a maximized economic benefit and minimized environmental violation risk. Optimized land-use allocation patterns can be generated from the proposed IFNLM.展开更多
