我国常年玉米播种面积近3亿亩,按传统播种方法亩播量2.5kg计算,共需杂交一代种7.5kg,加上需贮备的救灾备荒种子0.5亿kg ,总计需种8亿kg足矣。而1996年全国共生产玉米杂交种14亿kg,加之上年库存的2亿kg,共备种16亿kg。亦就是说,如无特殊情况,即便是1997年不搞制种仍能满足1998年全国玉米生产需要。这将会给各级种子部门背上极其沉重的经济包袱,如占用贷款支付利息,增加保管费,种子损耗,甚至不对路种子转商等,产生一系列不良后果。这不能不引起笔者陷入深深的思考。 Our country perennial corn sown area of ​​nearly 3 million mu, according to the traditional method of sowing acreage of 2.5kg, a total of hybrid generation of 7.5kg, plus the need to reserve disaster relief waste seeds 050 million kg, a total of 800 million kg need to be sufficient. In 1996, a total of 1.4 billion kg of maize hybrids were produced nationwide, plus 200 million kg of stocks in the previous year, for a total of 1.6 billion kg. In other words, if there are no special circumstances, even if we did not engage in seed production in 1997, we could meet the 1998 national corn production needs. This will bring extremely heavy economic burdens to the seed departments at all levels, such as paying interest on occupying loans, increasing custodian fees, loss of seeds, and even a wrong turn of seeds and seeds, which have a series of adverse consequences. This can not but lead the author into deep thinking.
