摘要
对紫色土旱地节水农业综合配套技术示范研究表明 :聚土垄厢、垄沟栽地膜春玉米、垄厢免耕播小麦、秸秆覆盖的栽培模式 ,可减少水土流失 ,增强抗旱能力 ,改善土壤性状 ,提高作物产量。聚土覆盖小麦产量达 5190 kg/ hm2 ,比对照小麦增产 18.2 %。是合理利用水资源 ,保土、保肥 ,能蓄能排的旱地节水农业夺取作物高产的有效措施。
The integrated technical measures for upland water saving agriculture was carried out. The results showed that ridge planting maize, non tillage wheat and straw mulch cultivation can reduce water and soil erosion, heighten drought resistant ability, improve soil properties and increase yield. Wheat yield for ridge and mulch cultuse is 5190 kg/ha, 18.2% increment than that of contrast. It is a national measure for utilizing water resource, conserving soil and fertility and achieving high yield.
