近几年,黄淮海平原每年植棉在5000万亩左右,占全国棉花面积的65％以上;单产居全国平均数之上,总产占全国总产的70％左右。据我们在该地区鲁、冀、豫一些县(市)的实践和调查,该地区不仅水、热、光等条件适宜植棉,而且土地资源较丰富,棉花增产潜力较大,只要进一步抓好物质和技术投入,稳定面积,提高单产,对我国棉花生产发展将有重大作用。 In recent years, the Huang-Huai-Hai Plain plants about 50 million mu of cotton annually, accounting for more than 65% of the national cotton area. The per-unit production is above the national average, with a total output accounting for about 70% of the country’s total output. According to our practice and investigation in some counties (cities) of Shandong, Hebei and Henan in the region, it is not only suitable for planting cotton under the conditions of water, heat and light, but also rich land resources and great potential for increasing cotton yield. Material and technical inputs, stable area and higher yields will play a significant role in the development of cotton production in our country.
