为了探讨棉花增产的新途径,我所根据国内外的植棉技术新进展,从一九七四年起,进行了高密度高产栽培试验,当年小面积试验获得了亩产皮棉二百零二点一斤,在此基础上,一九七五年扩大试种,并会同泥城公社横港三队、横沔公社沿南十一队等八个单位成立了协作试验,探讨高密度高产栽培规律,普遍获得成功,一般亩产比大田增二成左右。现根据我所二年来试种的情况,初步总结如下。
In order to explore new ways to increase cotton production, based on the recent progress in cotton planting at home and abroad, we conducted a high-density and high-yielding cultivation experiment since 1974. In that year, we achieved 200-mu A pound. On this basis, we expanded our trial planting in 1975 and set up a collaborative experiment with eight units including Hengcheng III of Haicheng commune and Yantai commune along the south 11th team to discuss the law of high-density and high-yielding cultivation , Generally successful, the average yield of about 20% increase over the field. Now according to my two years to try the situation, a preliminary summary is as follows.
