近年来,在灌区试验万株棉,出现了不少高产典型。1973年扶风县新集大队用3765与65(1)-37-6进行小面积万株棉试验,分别亩产皮棉201与162斤。1974年三队种万株棉4亩,亩产243斤,并在同一块棉田安排一般密度棉花12.4亩、移栽棉2亩作对照,品种均为鄂岱棉。现将栽培技术简结如下。一、万株棉的栽培管理:(1)适时早播。万株棉4月12日播种(一般密度4月9日播种;移栽棉3月15日育苗,4月25日移栽),等行距1.5尺,株距0.4尺,亩予留苗万株。(2)在冬深耕、冬灌蓄水的基础上,解冻后亩施底肥15大车,苗期5月31日施氨水35斤,蕾期6月23日施氨水40斤,花铃期7月19日施硫铵14.3斤、氯化铵13斤、棉渣15
In recent years, thousands of cotton plants have been tested in irrigation areas, with many high-yielding typical products. In 1973 Fufeng County, the new set of brigade with 3765 and 65 (1) -37-6 small area thousand strains of cotton test, respectively, 201 and 162 pounds of lint per mu. In 1974, the three teams planted 4 mu of cotton plants and produced 243 kg per mu. Arranged 12.4 mu of general-density cotton and 2 mu of transplanted cotton in the same paddy field for comparison, and the varieties were all E-Dai cotton. The cultivation technology is summarized as follows. First, 10,000 strains of cotton cultivation and management: (1) timely sowing. Ten thousand strains of cotton sown on April 12 (the general density of April 9 sowing; transplanting cotton March 15 nursery, April 25 transplanting), such as line spacing 1.5 feet, spacing 0.4 feet, mu to stay Miao million strains. (2) On the basis of deep plowing and winter irrigation and storage of water in winter, 15 limousine baskets of fertilizer were thawed, 35 kg of ammonia water was applied on May 31 of seedling stage, 40 kg of ammonia water on June 23 of budding stage and July On the 19th ammonium sulfate 14.3 kg, 13 kg of ammonium chloride, cotton residue 15
