春小麦是甘肃省河西灌区农业的主要粮食作物,常年种植面积450万亩以上,1980年平均单产已达到479.7斤,近年来,大面积亩产800——900斤已不属罕见;实行生产责任制后在井灌区不少粮食生产专业户的承包土地上,平均单产有的已上升到1000斤。所以,河西是甘肃省春小麦的高产区,也是全国春小麦单产较高的地区。我们经数年高产栽培和调查研究,整理出亩产800—1000斤的生态指标,可提供生产参考。一、品种河西春小麦品种,属于内陆生态型,春性,光照阶段反应中等。春化阶段历时较短,在田间条件下,出苗后10天左右,2.5—2.9叶龄时,生长锥开始伸
Spring wheat is the staple food of agriculture in Hexi Irrigation Area of Gansu Province. The annual perennial acreage is more than 4.5 million mu and the average yield in 1980 reached 479.7 kg. In recent years, it is not uncommon for large-scale mu produce 800-900 kg per mu. Implementing the production responsibility system After a lot of wells in the well-developed grain production contracted land, the average yield of some has risen to 1,000 pounds. Therefore, Hexi is a high-yielding area for spring wheat in Gansu Province and also a region with a relatively high spring wheat yield in the country. After several years of high-yielding cultivation and investigation, we sorted out ecological indicators of 800-1000 kg per mu yielding production reference. First, the variety Hexi spring wheat varieties, belonging to the inland ecotype, spring, light stage reaction medium. The vernalization stage lasted for a short time. Under field conditions, about 10 days after emergence and 2.5-2.9 leaf age, the growth cone began to stretch
