锦县是省重点商品粮基地县之一,历年高粱种植面积在40万亩左右,约占粮食作物面积的30%以上。高粱产量的高低,对全县粮食总产量影响很大。锦县地处辽西走廊,地形较复杂,耕地有山、平、洼,地力又分上、中、下;自然小气候差异较大。在高粱生产中,要做到适地适种,必须改变品种过分单一的状况,因此我们引进了高产高粱杂交种——辽杂四号试种,试图利用平肥地的地力发挥其高产优热,使全县粮食产量稳步增长。一、辽杂四号试种获成功辽杂四号是辽宁省农科院高粱研究所配制的杂交高粱新组合。1986年,我县引进试种。
Jinxian County is one of the key grain commodity counties in the province. The annual area of sorghum planting is about 400,000 mu, accounting for more than 30% of the total area of grain crops. The level of sorghum production, a great impact on the county’s total grain output. Jinxian County is located in the western Liaoning corridor, the terrain is more complex, arable land with mountains, flat, depression, fertility is divided into upper, middle and lower; natural microclimate differences. In the production of sorghum, to achieve the right species, we must change the over-single species condition, so we introduced the hybrid sorghum-Liaoza No.4, which is a high yielding sorghum hybrid. , So that the county’s grain output increased steadily. A Liaoza No.4 trial was successful Liaoza 4 is a new combination of sorghum made by Sorghum Institute of Liaoning Academy of Agricultural Sciences. In 1986, our county introduced trial planting.
