辽宁省葫芦岛市连山区位于辽西走廊,全区粮食作物耕地面积约4.3万hm2,其中玉米播种面积3万hm2,年产玉米约22万t,玉米产量占粮食总产量60%以上,所以,提高玉米产量,是直接提高全区粮食产量的关键。针对连山地区的气候特点,从2000年在全区试验推广常规玉米高产栽培技术的同时,重点推广了“抢墒播种、适时早播”的增产技术。试验证明,玉米适时早播,增产增收效果显著,是一项不需要增加成本、行之有效的增产措施,在辽西地区值得推广。
Lianshan District of Huludao City of Liaoning Province is located in the Liaoxi Corridor. The area of cultivated land for food crops is about 43,000 hm2, of which 30,000 hm2 are maize sown and about 220,000 t maize annually. Maize output accounts for more than 60% of the total grain output. Therefore, Raising corn production is the key to directly raising grain output in the region. In view of the climatic characteristics in Lianshan area, we popularized the technology of increasing yield of “sowing moisture and sowing timely and timely sowing” while popularizing conventional high-yielding maize cultivation techniques in 2000 in the whole region. Experiments show that timely sowing corn, increase production and income is remarkable, is a do not need to increase costs, effective stimulation measures, worth promoting in western Liaoning.
