兴平县西吴公社北马大队,认真贯彻毛主席“必须把棉花抓紧”的指示,虚心学习外地先进经验,积极采用棉花火炕营养钵育苗。1971年全大队育苗移栽50亩,实践证明能延长棉花生长期约一个月,提早生育期10至15天。1972年共移栽140亩,一般长势良好,早发、早熟,平均亩产皮棉149.8斤,较直播棉花高出23.8％。我们的做法是: 一、提前准备,培育壮苗。为了做好育苗工作,在冬春农闲季节,着手备料,保证料足和质量。解冻后,选择棉田附近避风向阳的地方建床,床长30尺,床宽4.2-4.5尺,床的大小要适宜,可长不可宽,过 Xingping County, North West Brigade brigade, conscientiously implement Chairman Mao’s “must grasp the cotton,” the instructions, humbly learning advanced experience in the field, and actively using cotton kang nutrition bowl nursery. In 1971 the entire unit nursery transplanting 50 acres, the practice proved to extend the cotton growing period of about one month, early growth period of 10 to 15 days. In 1972 a total of 140 acres of transplants, the general good growth, early, precocious, an average of 149.8 kg of mu per acre, 23.8% higher than the direct broadcast of cotton. Our approach is: First, advance preparation, nurturing strong seedlings. In order to do a good job nursery work, in the winter and spring slack season, proceed with the preparation, to ensure adequate material and quality. After thawing, select the shelter near the sunny place to build cotton shelves, bed length 30 feet, bed width 4.2-4.5 feet, the size of the bed should be appropriate, can not be long, too long
