前进农场去年有1,019亩春小麦,平均亩产542斤,比1958年单产133斤跃增了2.8倍多。主要的技术经验是:种牧草改良土壤,早耕、深耕该场土壤盐碱大、地力薄,用了种牧草(苜蓿和草木樨)培养地力的措施。去年的小麦大部分种在牧草茬地上,据调查,比种在其它茬地上的增产30%左右。同时,1958年9月以后,把大部分土地耕翻了2—4次,一般耕深一尺左右。施足基肥,适时追肥麦田普遍施肥,平均亩施基肥41,000多斤,比1958年增加四倍。这些基肥:一半在深耕时分层施入;一半在播前施入。播种时还施了种肥,每亩硫铵10 In the past year, there were 1,019 mu of spring wheat on average, with an average yield of 542 kilos per mu, more than 2.8 times the yield of 133 kilos in 1958. The main technical experience is: forage grass to improve the soil, early tillage, plowing the soil salinization, thin ground, with the kind of grass (alfalfa and herbs) to cultivate the soil of the measures. Most of last year’s wheat was planted in forage stubble fields, according to surveys, an increase of about 30% over that grown on other stubble fields. In the meantime, after September 1958, most of the land was plowed down 2-4 times, generally about a foot deep. Shizujifei, timely top dressing wheat general fertilization, the average mu base fertilizer 41,000 kilos, four times more than in 1958. These basal diets: half are applied in layers during plowing; half are applied before sowing. Planting fertilizer was also applied, per mu ammonium sulfate 10
