我们在当地党委的正确领导下,于1976～1978年进行春小麦高产栽培试验,经三年苦战,三年跨了三大步,取得了亩产突破千斤关的成绩。1976年试验田面积7亩,平均亩产634.0斤;1977年16亩,平均亩产745.2斤,内有2.6亩亩产812.3斤;1978年17.847亩,平均亩产816.88斤,内有2.6亩平均亩产1044.96斤,0.437亩折合亩产1441.64斤。三年的实践证明,只要坚持科学种田,春小麦产量就能大幅度提高。一、基本情况试验田设在固原头营公社农科站,位于东经106°,北纬36°,海拔1550米。属清水河流域的沈河水库灌区,灌溉便利。土地经三年培肥,有机质含量1.09％,全氮量0.082％,全磷量0.19％。去年麦收后种植绿肥,产草量约3000斤/亩,结合翻压,秋施高温堆肥约7方/亩,重点丰产田约8方/亩;春施农家肥3方/亩,磷酸二氢铵10～15斤/亩,油渣60～70
Under the correct leadership of the local Party committees, we conducted high-yielding spring wheat experiments from 1976 to 1978. After three years of hard fighting and three major strides in three years, we achieved successes in exceeding the minimum standards. In 1976, the experimental plot area was 7 mu with an average yield of 634.0 kg per mu; in 1977 16 mu, the average mu yield was 745.2 kg, with 2.6 mu mu yield of 812.3 kg; in 1978 17.847 mu, the average mu yield was 816.88 kg, with an average of 2.6 mu Production 1044.96 pounds, 0.437 mu 1441.64 kg equivalent mu yield. Three years of practice have proved that as long as scientific farming is carried out, the output of spring wheat can be greatly increased. First, the basic situation Experimental field is located in Guyuan Touying commune Agricultural Station, located 106 ° longitude, 36 ° north latitude, 1550 meters above sea level. It belongs to Shenhe reservoir irrigation area of Qingshui River basin, and irrigation is convenient. After three years of fertilizing the land, the organic matter content 1.09%, total nitrogen 0.082%, total phosphorus 0.19%. Last year, wheat harvest after planting green manure, about 3000 kg / mu of grass production, combined with pressure, autumn high temperature composting about 7 square / mu, focusing on high yield farmland about 8 square / mu; Ammonium 10 ~ 15 pounds / mu, oil residue 60 ~ 70
