复种糜子是引黄灌区一年两熟的一种主要栽培方式,也是充分利用地力,挖掘增产潜力,提高单位面积产量,增加粮食生产的一项增产措施.每年种植面积约40～50万亩,在全年粮食生产中占有一定比重,增产潜力很大.但当前存在着一种强调高产作物,忽视提高复种糜子产量的倾向.有些人认为,复种糜子产量每亩只有一、二百斤,把它看成是注定的“低产作物”;还有些人认为,复种糜子在全年粮食中比重不大,无足轻重.因此,对如何提高复种糜子的产量重视不够.
Multiple cropping is one of main cultivation methods of double irrigation in Yellow River irrigated area and also an increase measure of making full use of soil fertility, excavating yield potential, increasing yield per unit area and increasing food production.The annual planting area is about 40 ~ 500000 mu, Occupy a certain proportion in grain production throughout the year and have a great potential for increasing production, but at present there is a tendency to emphasize high-yield crops and neglect to increase the yield of milled broomcorn plants. Some people think that the output of milled broomcorn millet is only one or two hundred catties per mu. It is considered destined to be a “low yield crop.” Others think that the multiple crop of midbred millets is of little or no importance in the whole year’s grain production. Therefore, it is not enough to pay attention to how to increase the production of milled poplar.
