自1975年以来,我们每年种植小麦1,500—1,600亩,亩产500斤以上,并出现650斤以上生产队5个,700斤以上生产队1个,800斤以上高产田块40亩。通过几年的实践,在探讨小麦高产途径与技术措施的关系中,初步摸索出一些规律。我们认为,大面积亩产500—600斤水平,合理的群体结构大致是:基本苗18—22万,年前总分蘖数60—70万,年后最高分蘖数75—85万,每亩成穗28—34万,每穗粒数30—42粒,千粒重35—38克。小麦要高产,除群体要合理外,措施要跟上。一、狠抓播种关(一)打好土、肥、水基础:1.深耕细作,提高耕作质量:整地好坏是一播全苗的关键。近几年有个别队耕作粗放,耕层浅,缺苗 Since 1975, we have planted 1,500-1,600 hectares of wheat per year and have produced more than 500 kilograms of mu per mu and have produced more than 650 kilograms of production corps, 1 production team of more than 700 kilograms and 40 acres of over 800-kilogram high yield plots. After several years of practice, some preliminary laws have been explored in exploring the relationship between the high-yielding ways of wheat and technological measures. We believe that a large area of ​​500-600 kg per mu level, a reasonable population structure is roughly: basic seedlings 182 000, the total tiller number 60-70 million years ago, after the highest tiller number 75-85 million per acre into Spike 28-340000, grain number per spike 30-42, grain weight 35-38 grams. Wheat to high yield, in addition to the group to be reasonable, the measures to keep up. First, pay close attention to seeding (a) lay a good foundation soil, fertilizer, water: 1. Deep plowing and improve the quality of farming: land preparation is the key to a good seedlings. In recent years there are individual teams extensive farming, shallow tillage, lack of seedlings
