伊犁地区是自治区玉米高产区之一。86年全区玉米总面积56万亩,平均单产348公斤,杂交种面积占玉米总面积的82.9％,86年所种的Sc704杂交种有6.5亩创造了我区平均单产1150公斤的新记录。 1.采用高产杂交种 玉米杂交种是由两个遗传性不同的自交系杂交而成,所以其生活力强,生物特性和生理机能大大超过了常规品种,表现出株形
Ili region is one of the autonomous regions corn high yield area. In 1986, the total area of maize in the whole region was 56,000 mu, with an average yield of 348 kg. The area of hybrids accounted for 82.9% of the total area of maize. 6.5 mu of Sc704 hybrids in 86 years created a new record of an average yield of 1150 kg in our region. 1. The use of high-yielding hybrids Maize hybrids from two hereditary inbred lines of different hybrids, so its strong viability, biological characteristics and physiological functions greatly exceeded the conventional varieties, showing the shape
