我区杂交玉米制种的田地,长期以来均处于单一的生产种子状况,虽随着制种技术的改进,单产逐年得到提高,目前全区制种平均单产390公斤,高产的新平县全县平均超过570公斤。制种亩收入一般达到750元左右,当季经济收益仍不高。能否综合利用制种田有限的土地,提高制种田当季的效益,探求农业综合高效生产途径,达到综合利用制种田,集约经营,实现两熟变三熟,确保制种田当季收入超千元的目的。自1991年起我们先后在峨山县、新平县、江川县等玉米制种基地,结合实施制种推行父本雄花散
Although the field of hybrid corn production in our region has long been in a single state of seed production, with the improvement of seed production techniques, yield has been increased year by year. At present, the average yield of whole-region seed production is 390 kg. The average high-yield Xinping County county average Over 570 kilos. Produce acres of income generally reached 750 yuan, seasonal economic returns are still not high. Can comprehensive utilization of the system of limited land for farming, improve the efficiency of the season farming, to explore comprehensive and efficient agricultural production channels to achieve comprehensive utilization of the system of farming, intensive management, to achieve two ripening three to ensure the system of farming income of more than a thousand dollars the goal of. Since 1991, we have in Maishan County, Xinping County, Jiangchuan County and other maize seed production base, combined with the implementation of seed production to promote male male flowers scattered
