| The trial was conducted on the base of other studies.Using the 3502 dairy farm for test environment.By using the combination design of orthogonal pivoting and quadratic regression equations. Five factors selected in the experiment were the varieties zinc, boron, copper, manganesemolybdenum. Research factors on corn silage yield and quality, The cultural mathematical model was set up by computer. The relation between rape yield and quality and the cultural measure were analyzed by computer. The following conclusion were thus obtained.1. Analysis of various factors in the effects of corn silage yield,crude protein, crude fat, crude fiber, acid detergent fiber, neutral detergent fiber, manganese, copper, zinc content . Various factors on the yield of the order of: Zinc, molybdenum fertilizer> Boron> copper fertilizer, manganese fertilizer; Various factors on the impact of neutral detergent fiber sequence: Boron> zinc, manganese fertilizer, molybdenum fertilizer> copper fertilizer; Various factors on the impact of neutral detergent fiber: Copper fertilizer> Zn> Mn fertilizer> boron> molybdenum fertilizer; Calcium content of various factors on the impact of the order of:Molybdenum Fertilizer> fertilizer Mn> Zn, Boron> copper fertilizer; Phosphorus content of various factors on the impact of the order of:Boron> molybdenum fertilizer> zinc, manganese fertilizer, copper fertilizer.2. Analysis of interaction impact indicate, the interactions which have a notable impact on yield are zinc and copper, zinc and molybdenum,boron and molybdenum; the interactions which have a notable impact on the content of crude protein are boron and molybdenum; the interactions which have a notable impact on the content of NDF are zinc and boron, copper and boron, boron and molybdenum; the interactions which have a notable impact on the content of ADF are copper and boron; the interactions which have a notable impact on the content of calcium are zinc and copper, manganese and molybdenum, copperd and boron; the interactions which have a notable impact on the content of phosphorous are zinc and copper, zinc and molybdenum, boron and molybdenum; the interactions which have a notable impact on the content of zinc are manganese and boron; the interactions which have a notable impact on the content of copper are zinc and boron, manganese and molybdenum; the interactions which have a notable impact on the content of boron are copper and manganese, copper and molybdenum.3. zinc sulfate was applied 28.75kg/hm~2,manganese sulphate was applied 10kg/hm~2, copper sulfate was applied 30kg/hm~2,borax was applied 5kg/hm~2,molybdate was applied when the output of the best 0.93kg/hm~2.Can achieve the optimal level of simulation. |
