近几年来秋收之后,在我省关中各地到处可以看到焚烧玉米秸秆的现象。据统计,我省每年种植玉米1,500多万亩,每亩可收玉米秆220公斤,共可收33亿多公斤。但长期以来这些资源得不到合理的利用。大量的秸秆被作为燃料烧掉,贫瘠的土地因得不到有机质的补偿而不断衰竭。致使土壤胶体品质变差,结构变坏,肥力不断下降,产量不断降低。 After the autumn harvest in recent years, we can see the phenomenon of corn stalks everywhere in Guanzhong. According to statistics, more than 15 million mu of corn are planted every year in our province, 220 kg of corn stalk per mu can be harvested, totaling more than 3.3 billion kilograms. However, these resources have not been properly used for a long time. Large amounts of straw are burned as fuel, and barren land is depleted due to lack of compensation for organic matter. Resulting in deterioration of soil colloidal quality, structural deterioration, fertility continued to decline, production continued to decline.
