我们根据夏播棉生育期短的特点和本地试种麦茬棉的经验教训,去年作了麦茬棉高密、早熟的试验,获得成功。实验田面积1.525亩,黄壤土,中上等肥力,播前测验土壤含有机物质0.8%,水解氮70ppm,硝态氮21ppm,铵态氮9ppm,速效磷42ppm,速效钾100ppm,前茬小麦亩产683斤。夏播棉6月4日播种,9月15日吐絮,11月15日收摘完毕,田间生长期164天。每亩平均实收皮棉118.3斤,其中霜前棉90斤,占76.1%,霜后花18.06斤,占15.2%,僵瓣花10.22斤,占8.7%,斤棉均价为1.38元,每斤不完全农本(种、肥、药、耕作)0.053元。
According to the characteristics of summer sowing cotton short duration and the local experience of training wheat stubble, wheat stubble last year made high density, precocious test, success. Experimental field area of 1.525 acres, yellow loam soil, middle and upper fertility, before sowing test soil organic matter content of 0.8%, hydrolyzed nitrogen 70ppm, nitrate nitrogen 21ppm, ammonium nitrogen 9ppm, available phosphorus 42ppm, available potassium 100ppm, Producing 683 pounds. Summer cotton sowing on June 4, September 15 Ipomoea, November 15 to close the end of the harvest, field growth period of 164 days. The average amount of lint per acre 118.3 kg, of which 90 kg frost before the cotton, accounting for 76.1%, 18.06 kg after the flower frost, accounting for 15.2%, 10.22 kg stiff petal, accounting for 8.7%, average price per kilogram 1.38 yuan per catty Incomplete farming (species, fertilizer, medicine, farming) 0.053 yuan.
