摘  要:
试验结果表明,双价转基因抗虫棉新品种中棉所45,在豫东周口市麦棉套作区种植,适宜施N水平为112.5-187.5kg/hm2,皮棉产量可迭1259.45kg/hm2以上,产量构成因素协调,经济效益好,元氮肥纯增值4元,病虫害发生较轻,增值大。在较低施氮水平,能获得较高皮棉产量,高产低成本,是中棉所45在当地表现突出的优良特性。

摘  要:
Results of this experiment showed, for CCRI 45 growing in cultivated region in Zhoukou in eastern Henan Province the most suitable application N levels were 112.5-187.5kg/hm2, highest fiber cotton yields could reach 1259.45kg/hm2, production structure factors were reasonable, economic benefit is very good, net income increased 4 yuan compared with no N, the insect and pest occurred lightly. Output Value increased greatly. High fiber cotton yields were received at lower N levels, it's outstanding advantage for CCRI 45 to turn low cost to high yield.
