A Research Report on the Effect of Different Application Rate of Inorganic Base Fertilizer to Yield and Quality of Garden Cane (Part Ⅱ)
Result of the research indicated that inorganic base fertilizer of 300 kg/bm2 promoted the rate of emergence, plant height, diameter, stalk weight and numbers of millable stalks. The yield was increased outstandingly; the stalk became softer than that without inorganic basefertilizer. Commercial characters and technological characters turned better, and it had almost no effect to resistance. Fertilization cost of this application rate was the lowest but the yield and the economic effect was the best and therefore might be the first choise in garden cane production. Application rate of 600 kg/hm2 promoted obviously the height, diameter and stalk numbers. The yield was increased notably; the emergency rate and tillering rate was slightly better.Technological and commercial characters were slightly improved and there was no noticeable harmful effect to resistance. The cost and the economic effectiveness were secondary, and it might be second best choice in the production. Application rate of 900 kg/hm2 promoted the rate of tillering, height, diameter, stalk weight and stalk numbers. The yield was increased remarkably. It ameliorated technological characters. But it reduced rate of emergence and worsened most commercial characters. The cost and the effect were 3rd, and therefore should not be used for the production. Application rate of 1200 kg/hm2 increased the height, numbers and yield. It slightly improved the tillering and stalk diameter, but it reduced obviously the rate of emergence, most technological and commercial characters. The cost was the highest but the effect was the lowest, so this application rate should not be emplyed in the production.
