小麦沟播集中施肥技术是通过施肥沟播机一次实现沟播集中施肥农艺要求,是中低产区小麦稳定增产的有效措施。据中国农科院在京、津、冀、晋、豫、陕等省市100余点多年沟播集中施肥试验示范,一般较平播对照增产10％—30％,平均增产14.7％,表现出稳定的抗逆增产效应。陕西省粮作所与永寿县农技站近年在渭北旱塬永寿县等地试验和大面积示范,采用沟播集中施肥
Wheat ditch broadcast concentrated fertilization technology is through a fertilization ditch sowing time to focus on the requirements of agronomic fertilization, wheat is an effective measure to increase wheat yield in middle and low yield areas. According to the Chinese Academy of Agricultural Sciences in Beijing, Tianjin, Hebei, Shanxi, Henan, Shaanxi and other provinces and cities more than 100 years of years of concentrated fertilization experimental demonstration ditch, compared with the general increase of 10% -30% compared with the broadcast, an average increase of 14.7%, showing stability The anti-infective effect of increase. In recent years, the Grain Crops and Yongshou Agricultural Station of Shaanxi Province have experimented and large-scale demonstration in Yongshou County and other places in the Weibei Highland,
