全苗是棉花丰产的基础。早苗、齐苗、壮苗又是高产的重要保证。多年的生产实践证明,无论是丰产田或一般田都有相当面积的棉田抓不住全苗。据朝阳地区农业局1981年6月20日统计,全区18.8万亩棉田,八成苗以上的有12.7万亩,仅占67.58%;六成到七成的有5.1万亩,五成以下的有1万亩,后两类占32.44%,对总产影响很大。影响朝阳棉花全苗主要有两个原因。一是自然环境条件。朝阳处于北方干旱特早熟棉区,基本上是旱作农业,地形复杂,土壤类型较多,气候变化很大。二是播种技术。据多年试验观察和总结广大棉农的经验,认为要一次播种,保住全苗,必须抓住十项措施,因地制宜分项实施,综合运用。
Full seedling is the basis for high yield of cotton. Sanae, Qi Miao, strong seedlings is an important guarantee of high yield. Years of production practice has proved that both the high yield fields or fields generally have a considerable area of cotton can not catch the whole seedlings. According to the statistics of the Chaoyang District Bureau of Agriculture on June 20, 1981, the total area of 188,000 mu of cotton fields in the region is 127,000 mu, accounting for 67.58% of the total; 80,000 to 70% of the area has 51,000 mu and less than 50% 1 mu, the latter two accounted for 32.44%, a great impact on the total output. Affect Chaoyang cotton seedlings for two main reasons. First, the natural environment conditions. Chaoyang is located in the arid and precocious cotton area in the north, which is basically arid agriculture with complex terrain, more soil types and great climate change. Second, sowing technology. According to years of experimental observation and summarization of the experiences of the vast number of farmers, it is considered that once planting and preserving whole seedlings, ten measures must be taken and implemented in accordance with local conditions and implemented comprehensively.
