临县任家坪大队,1981年麦地回茬谷子120亩,平均亩产600斤,较去年提高20%。任家坪位于临县南部的湫水河大川,灌溉条件较好,819亩农田中,水地380亩,占46.4%。气候较暖,年均气温11℃左右。加上人多地少,667人,平均耕地1.24亩。所以几年来大部分水地由一年一作变一年两作或两年三作。1981年,在回茬谷子上采用了以下技术措施:一、力争早播,培育壮苗播期对抽穗、成熟起决定性的作用,早播是回茬谷子高产的关键。往年夏收得7—8天,犁地翻粪再用4—5天。而去年夏收较往年早3—4天,7月2—5日播种又推广了硬茬(收麦后不耕)下种,所以比往年早播7—9天。加上夏收前浇水一次,墒情不错,每亩用15斤硝铵 Lin County Renjiaping brigade, in 1981 wheat field 120 acres of stubble, the average yield 600 pounds, up 20% over last year. Renjiaping is located in the south of Linxian River Dashui River, irrigation conditions are better, 819 acres of farmland, water 380 mus, accounting for 46.4%. The climate is warmer, with an average annual temperature of about 11 ℃. With more people and less, 667 people, an average of 1.24 acres of arable land. Therefore, in recent years most of the water will be transformed from one year to two or three years in a year. In 1981, the following technical measures were adopted on the stubble backfill: First, striving to be early sowing, cultivating strong sowing sowing date has a decisive effect on heading and maturity. Early sowing is the key to high yield of stubble. Last summer, received 7-8 days, plowing the dung again 4-5 days. Last summer last 3-4 years earlier than in previous years, July 2-5 sowing and promotion of hard stubble (after harvesting wheat does not plow) under the species, so as early as in previous years, 7-9 days. Coupled with the summer before the watering once, good moisture, with 15 kg of ammonium nitrate per acre
