丰城县荣塘乡位于赣江东岸,是一个低丘红壤老棉区。1981年以来,棉花单产连续七年上升,1981年单产皮棉只有63斤,到1986年达120斤,总产皮棉1.023万担,创历史最高水平。1987年单产、总产比1986年增长10％左右,单产132斤,总产1.116万担。据收购部门统计,棉花品质优良,1987年品级为3.12级,纤维长度28.6毫米,衣分39.6％,每担卖价182.33元,比1986年提高11.08元。1987年全乡棉花总产值281万元,比1986年平均亩增经济收入21.6元。荣塘乡夺取棉花优质高产,采用了一套“三促一防”的水肥管理技术,做到苗期轰得起(壮苗早发)、蕾期搭好架(果枝多,花蕾大)、花桃期旺盛(青枝绿叶花桃多)、后期不早衰(老健叶不黄)。现介绍如下:
Fengcheng County Rongtang Township is located in the east bank of Ganjiang River, is a low hill red cotton area. Since 1981, cotton yield has risen for seven consecutive years. In 1981, only 63 kg of lint per unit was obtained, up to 120 kg in 1986 and 1.023 million lint of total lint, a record high. Yields in 1987, the total output increased by about 10% over 1986, yield 132 pounds, with a total output of 111,600. According to the statistics of the purchasing department, the quality of cotton was good, with the grade of 3.12 in 1987, the fiber length of 28.6 millimeters, the percentage of clothing 39.6% and the selling price of 182.33 yuan per piece, an increase of 11.08 yuan over 1986. In 1987, the township’s total output value of cotton was 2.81 million yuan, an increase of 21.6 yuan over the 1986 average economic yield. Rongtang won the high quality cotton yield, using a set of “three to promote a defensive” of water and fertilizer management techniques, so that the seedling can afford to boom (strong seedlings early hair), bud stage set up (fruiting branches, buds large) Flower peach exuberant (green leaves Peach more), late premature aging (old healthy leaves not yellow). Now introduced as follows:
