近年来,花生地膜覆盖栽培虽有飞速发展,但露地栽培仍有相当面积,提高这部分花生的产量十分重要。实践证明,高垄作和半高垄作是提高露地花生的一项有效措施。据金县农业局试验,高垄花生平均亩产441.8斤,半高垄亩产433.8斤,分别比低垄增产20.2％和18.0％。高垄和半高垄可增加土壤与大气的接触面积,受光面大,能够吸收更多的热量,提高地温,加大土壤昼夜温差。据华家乡农
In recent years, although peanut mulching has developed rapidly, there is still a considerable area of open-field cultivation. It is very important to increase the output of this part of peanut. Practice has proved that high ridge and semi-high ridge is an effective measure to improve peanut open field. According to Jin County Bureau of Agriculture test, the average yield per acre 441.8 kg high ridge, semi-high ridge yield 433.8 kg, respectively, 20.2% and 18.0% higher than the low ridge. High ridge and ridge can increase the contact area of the soil and the atmosphere, the light-emitting surface, can absorb more heat, increase ground temperature, increase soil temperature difference between day and night.
