184团位于准噶尔盆地西北边缘,地理位置:北纬46°02′～46°23′,东经86°13′～86°28′,受北冰洋和古炙斑通古特沙漠的影响,形成典型的大陆性气候。≥10℃的年积温为3400℃左右,年平均气温5～7℃,极端高温41.9℃,极低温-37.2℃。无霜期159～203天,年平均降水87毫米,蒸发量2283毫米。土壤属灰漠土,土质大部分为重壤土。通过近几年在棉花栽培上的不断试验,其结果表明,新陆早7号、8号、10号比较适宜我区种植,最佳播期是4月中旬。一、品种选择主要选择早熟品种,如新陆早7号、8号、10号等。二、栽培要点1.整地、施肥与播种①整地与施肥头年9月下旬进行茬灌,秋耕前清膜、灭茬,进行全层施肥,秋翻深度25厘米以上,
184 is located in the northwestern edge of Junggar Basin, the geographical location: latitude 46 ° 02 ’~ 46 ° 23’, longitude 86 ° 13 ’~ 86 ° 28’, by the Arctic Ocean and ancient Sunburn Tonggut desert, forming a typical continent Sexual climate. ≥10 ℃ annual accumulated temperature of about 3400 ℃, the annual average temperature of 5 ~ 7 ℃, extreme high temperature 41.9 ℃, very low temperature -37.2 ℃. Frost-free period of 159 to 203 days, the average annual rainfall of 87 mm, evaporation 2283 mm. Soil is gray desert soil, soil mostly heavy loam. Through continuous experiments on cotton cultivation in recent years, the results show that Xinluzao No. 7, No. 8 and No. 10 are more suitable for planting in our district, and the best sowing date is in mid-April. First, the choice of varieties The main choice of precocious varieties, such as the New Land early 7, 8, 10 and so on. Second, the cultivation points 1 preparation, fertilization and sowing ① preparation and fertilization the first year in late September stubble irrigation, autumn before the Qing membrane, stubble, full-thickness fertilization, turning depth of more than 25 cm,
