我们班的棉花丰产试验田,面积半亩,土壤砂质,前作小麦,于5月22日收割,棉花移栽前进行了两犁两耙。棉花品种为鄂光棉。于4月21日播种育苗,5月26日移栽,6月10日现蕾,7月4日开花,8月2日吐絮,10月25日拔杆,皮棉单产203斤。棉花品质较好,单铃重5.3克,衣分40.3％,纤维长度30.8毫米,纤维整齐度为98％,霜前花占总收花的90％。今将试验小结如下: 一、适早播种,苗齐苗壮毛主席教导我们:“第一个战斗的胜败给予极大的影响于全局”。适时早播,培育壮苗是夺取棉花高产的第一关。我班棉花4月21日播种,比一般大田早播5—10天。为了苗 Our class of cotton yield test field, an area of ​​half acres, sandy soil, before the wheat, on May 22 harvest, cotton transplanting before the two plow two rakes. Cotton varieties for the E light cotton. Sowing seedlings on April 21, transplanting on May 26, budding on June 10, flowering on July 4, digging on August 2, pulling rod on October 25, and lint yield 203 kg. Cotton quality is good, boll weight 5.3 grams, 40.3% clothing, fiber length 30.8 mm, fiber uniformity of 98%, frost before the flowers accounted for 90% of the total income. The experiment is summarized as follows: First, the early sowing, seedling Qi Miao Chairman taught us: “The first battle victory or defeat to give a great impact on the overall situation.” Timely sowing, nurturing strong seedlings is to seize the first high yield of cotton.
