解放后,淮北地区小麦生产经历了漫长曲折的发展过程。1987年单产突破250kg后,出现10年徊徘,至1997年亩产才突破350kg,开始走上高产台阶。10年徊徘,除一些年份遇到不可抗御的自然灾害外,主要是指导本地区小麦高产栽培的理论和技术不配套。1 淮北地区小麦生产发展阶段 低产阶段:1949—1978年,小麦亩产在100kg以下,产量低而不稳,提高缓慢;生产上使用老品种,依靠土壤自然肥力和少量农家肥。这一阶段可称为“自然产量阶段”。 中产阶段:小麦亩产超过100kg,标志着开始进入中产水平。
After liberation, wheat production in Huaibei experienced a long and tortuous development. After the yield hit 250kg in 1987, there was a ten-year stagnation. By 1997, the mu production exceeded 350kg and started to take the high-yielding stage. In addition to some natural disasters that have become irresistible in some years, the theory and technology that mainly guide the high-yield cultivation of wheat in the region are not compatible. 1 Wheat Production in Huaibei During the low-yield stage of wheat production, from 1949 to 1978, the output of wheat was below 100 kg per mu and the yield was low and unstable, which was slow to increase. The old varieties of wheat were used for production, relying on the natural fertility of soil and a small amount of farm manure. This stage can be called “natural production stage.” Middle stage: Wheat yields more than 100kg, marking the beginning of entering the middle class.
