1987年县良种公司从山东引进14万斤鲁棉六号良种,在三里、流泗、马影等乡进行试种,获得了棉花增产、效益增值的好结果。如三里乡植棉面积3164亩,上交国家皮棉379255斤(不含棉农的自留棉),亩产皮棉119.9斤,比1986年每亩增产皮棉39.67斤,增产率为49.44％。虽然1987年雨水比较调和,对棉花生长极为有利,各地棉花产量有不同程度的增产。但全县皮棉平均亩产91.1斤,比1986年增产16.4斤,增产率为20.2％。而三里乡1987年每亩皮棉增产率比全县高29.4％,由此足以说明,鲁棉六号棉花良种在增产上所起的显著作用。
In 1987, the county seed company introduced 140,000 kg of Shandong Lushun No.6 seed from Shandong, and tried planting seeds in Sanli, Liusi and Maying townships, obtaining good results of cotton yield increase and profit growth. Such as Sanli Township, cotton planting area of 3164 acres, 379,255 kg of national lint turned over (excluding cotton farmers self-sustaining cotton), 119.9 kg of mu of lint per acre than in 1986 increased 39.67 pounds of lint per acre, an increase of 49.44% yield. Although the rain in 1987 more harmonic, extremely beneficial to the growth of cotton around the cotton yield have different levels of yield. However, the average output of lint cotton in the county was 91.1 kg, an increase of 16.4 kg over 1986, with an increase rate of 20.2%. However, the increase rate of lint per mu in Sanli Township in 1987 was 29.4% higher than that of the whole county, which is enough to show the significant role of Lushian 6 cotton varieties in increasing yield.
