In order to change this situation, in addition to adopting conventional measures, the scientific and technological group under the leadership of the Party branch of the brigade, - 1975 short stubble cotton cultivation experiments in 1975 experimental plot area of 1.2 acres, an average of 204 acres of lint yield per mu, control lint weight 120 kg (density are 5300 strains) .Specific practices are: cotton plant growth into the bud When starting from the bottom of the fruit skills, the tip of each fruiting branch of the tender and young buds removed, leaving each school only buds near the base of 1-2 To make full use of space, to extend between the rows of branches can be Appropriate to stay 1-2 buds. Short cut fruiting branches generally 3-4 times, each
