风沙半干旱区谷子花生间作效应研究

Research for Effect on Intercropping of Millet and Peanut of Aealian Semi-arid Region

风沙半干旱区风多风大、年降水量少、土壤水分蒸发量大、土壤风蚀沙化强烈、土地产出率低。谷子花生均为较耐干旱、耐瘠薄作物,但花生单作刨收后裸茬地表在风力的作用下易风蚀沙化。谷子花生带状间作有效地削弱了近地表20 cm高度风速、降低了地表风蚀度、减少了耕层0～10cm土壤水分蒸发量,提高了土地产出率,调整了风沙半干旱区农田作物空间配置结构。

In the aealian semi-arid region, the wind was constant and strong, lack of precipitation ,water of soil evaporate quickly, wind erosion and desertification of the soil are servious, output ratio was low. Millet and peanut belong to the crop who were drought resistant and barren resistant, but after harvesting of the peanut , the naked soil can be desertificated easily. After intercropping of millet and peanut, the speed of the wind higher 20 centimetre than the soil surface was decreased, surface erosion was reduced, the amount of evaporated water of the 0 to 10 centimetre soil has decreased, output ratio of soil has been increased, crop space configuration of aealian senti-arid region has been adjusted
