为了探索探墒沟垄种植方式在山西中部旱区的应用效果,以旋耕为对照,研究了免耕、探墒浅沟垄种植和探墒深沟垄种植对土壤含水量动态变化、玉米出苗率、农艺性状以及产量的影响。结果表明,玉米生长不同时期2种探墒沟垄种植土壤含水量均较免耕和旋耕高,旋耕土壤含水量最低;探墒深沟垄种植玉米出苗率最好,比旋耕种植出苗率平均提高15.7百分点,玉米株高、茎粗、叶面积和穗位高均有明显提高,有助于生长中后期干物质积累,提高产量。探墒沟垄种植是山西省中部旱地一种比较适宜的御旱抗逆种植方法。
In order to explore the effect of planting furrows and furrows in arid areas in central Shanxi, the effects of no-tillage, furrow planting with shallow furrows and deep trench furrows on dynamics of soil moisture content, maize emergence Rate, agronomic traits and yield. The results showed that the soil moisture content of two kinds of furrows with different stopes during the growth of maize was higher than that of no-tillage and rotary tillage, and the content of soil moisture of rotary tillage was the lowest. Average rate of increase of 15.7 percentage points, corn plant height, stem diameter, leaf area and ear height were significantly increased, contribute to the growth of mid-late dry matter accumulation and increase yield. Sowing ditch furrow planting is a more suitable drought-resistant planting method in dryland in central Shanxi Province.
