Study on the Windproof Effect of Different Strains of Quinoa in the Northern Foothills of Yinshan Inner Mongolia
Different strains of quinoa were artificially cultivated in the northern foothills of Yinshan,Inner Mon-golia.The HOBO data acquisition instrument was used to observe the windproof effect of quinoa fields during the filling and mature stages under different plant spacing and row spacing configurations.The results showed that:① under different plant spacing,the wind prevention efficiency of different strains of quinoa fields decreased with the increase of leeward distance,and the wind prevention efficiency decreased with the increase of plant spacing.The wind prevention efficiency in the mature stage was greater than that in the filling stage,which was 4.02％higher than that in the filling stage.The wind prevention efficiency of WD-9 quinoa was 8.63％～68.83％,which was 9.28％higher than that in the filling stage.The wind prevention efficiency of W-7 quinoa was 2.14％～56.46％,which was 15.12％higher than that in the filling stage.② Under different plant spacing,the variation pat-tern of surface roughness is the same as the wind prevention efficiency,which is 0.65cm higher than the average roughness at 1 hour after the filling period in quinoa fields.The maximum roughness of WD-9 quinoa during the filling period is 6.73cm,and the minimum roughness of W-19 quinoa is 2.79 cm.The maximum roughness of WD-9 quinoa field during the mature period is 7.50 cm,and the minimum roughness of W-19 quinoa field is 3.56 cm.③ Under different row spacing,the wind prevention efficiency of different varieties of quinoa fields is greater during the mature stage than during the filling stage,and reaches its maximum at the last 1 hour of the quinoa field.Among them,the wind prevention efficiency of WD-9 quinoa field at the last 1 hour is 76.44％～69.89％,which is 10.48％higher than during the filling stage.The windproof efficiency of the leeward surface in quinoa fields decreases with increasing row spacing from 0H to 5H,and the average windproof efficiency is 5.71％higher than that during the grouting period.The windproof efficiency of the leeward surface in quinoa fields increases with increasing row spacing from 7H to 9H,and the average windproof efficiency is 2.00％higher than that dur-ing the grouting period.④ Under different plant spacing,the variation pattern of surface roughness is the same as the wind prevention efficiency.The roughness is highest at 1H on the leeward side.Among them,the average roughness of WD-9 quinoa is the highest at 10.91 cm,which is 0.98 cm higher than the grouting period.The aver-age roughness of W-19 quinoa is the lowest at 6.88 cm,which is 0.42 cm lower than the grouting period.The roughness of the leeward surface in quinoa fields decreases with increasing row spacing from 0H to 5H,which is 10.48％higher than that during the filling period.The roughness of the leeward surface in quinoa fields increases with increasing row spacing from 7H to 9H,which is 10.48％higher than that during the filling period.WD-9 qui-noa in different strains can have better windproof effects under different configuration conditions.
