Effect Of Castor Cake And Fertilizer On Maize And Cole Growth And Yield

By studying maize and oilseed rape trials studied different ingredients Castor and inorganic fertilizer treatments on the growth and yield of maize and oilseed rape and the influence of soil bulk density. Designed to explore the best proportion of Castor and inorganic fertilizer, provide the basis for the development of castor bean organic fertilizer. Experimental study on the main following results were obtained:Each basin with 4g urea and 8g Calcium superphosphate can increase corn plant height, stem diameter and leaf area better. Each basin with 100 g Castor bean cake, 4g urea and 8g superphosphate have no significant difference with each basin with 4g urea and 8g superphosphate in maize growth. Each basin with 100 g castor bean cake, 8~16g urea and 8~24g calcium superphosphate on maize growth effect is better than every basin with 4 g urea and 8g calcium superphosphate group. Each basin with 100 g castor bean cake, 4g urea and 8g superphosphate compare to each basin 4g urea and superphosphate with 8g treatment can significantly improve the growth of corn.Biological yield of corn with the amount of application of inorganic fertilizer increased after decreased trend. When each basin deal with 100 g castor bean cake, 4g urea and 8g calcium superphosphate, the biological yield of corn is the largest. Which is more than 58% to the control group. The fertilizer made a negative correlation to the corn grain yield. When each basin deal with 100 g castor bean cake, 4g urea and 8g calcium superphosphate,the corn grain yield is the largest. which is more than 12% to the control group.Each basin deal with 100 g castor bean cake, 4~8g urea and 8~16g calcium superphosphate can significantly increase the plant height growth of rapeseed. Each basin deal with 100 g castor bean cake, 4g urea e and 8g superphosphate can significant increase the root length and stem diameter of rape.Each basin deal with 100 g castor bean cake, 4~8g urea and 8~12g calcium superphosphate can increase the fresh weight and dry weight of rape. Each basin deal with 100 g castor bean cake, 8~16g of urea and 8~24g calcium superphosphate cannot increase the rape production of fresh weight and dry. Each basin deal with 100 g castor bean cake, 4g urea and 8g superphosphate can best to improve the rape production.
