塔城公社农科大队有六个生产队,耕地500亩,地势平坦,粮棉混作。过去以种水稻为主,1972年开始种棉。由于水田刚改旱地,土壤含水量大,有冷、板、粘三种弊病。棉花前期不发,后期旺长,造成高大空。再加上掌握不住栽培技术,当年亩产只收30多斤。以后逐年摸索,积累了水田改旱地种棉的经验,植棉面积逐年扩大,产量逐年上升。到八○年植棉120亩,亩产116斤,八一年植棉面积扩大到250亩,亩产143.8斤,比历史上最高年平均每亩增长12.4％。棉花品级也较高,从交售给国家的皮棉来看,一、二级花占90％以上。八一年棉花生产能获得创历史最高水平的好成绩,基本经验主要针对全苗难保,早发难争,蕾期难稳,脱落难办,早衰难防五个难关实行了“五抓五争”。 Tacheng commune agricultural unit has six production teams, 500 acres of arable land, flat terrain, grain and cotton mixed. In the past to grow rice-based, 1972 began planting cotton. As paddy field has just changed the dry land, soil moisture content, cold, board, sticky three shortcomings. No early cotton, the late flourishing, resulting in tall and empty. Plus can not grasp the cultivation techniques, when the mu yield received only 30 kilos. After years of exploration, accumulated experience in paddy fields to dry upland cotton, cotton area has expanded each year, the output increased year by year. By 1980, 120 mu of cotton was planted and 116 pounds of mu per mu were produced. In 1981, the cotton area was expanded to 250 mu and 143.8 kg of mu per mu, an increase of 12.4% over the highest annual average in history. Cotton grade is also higher, from the sale of cotton to the country point of view, one or two spend more than 90%. Cotton production in August achieved a record high in history. The basic experience was mainly aimed at ensuring that all seedlings could not be covered. Early development was difficult, buds were not stable, .
