植树造林与退耕还林的根本目的,是为了控制水土流失,改善生态环境,提高经济效益,再造秀美山川,实现上游不受穷,下游不受灾,全国不受害(沙尘暴),人民能富裕的远大目标。而植树造林与退耕还林的基础是整地,只有科学的标准化整地,只有把跑水、跑土、跑肥的“三跑”变为集水、集土、集肥的“三集”,才能保证植树造林与退耕还林的高成活、高生长和高效益,才能实现植树造林与退耕还林的根本目的,否则,必然是劳民伤财,得不偿失。一、什么是科学整地根据“水是生命之源,土是生存之
The fundamental purpose of afforestation and returning farmland to forests is to control soil and water loss, improve the ecological environment, improve economic efficiency, rebuild the beautiful mountains and rivers, achieve the goal of not being impoverished in the upper reaches, no disaster in the lower reaches, no harm to the whole country (sandstorm) and people being rich . The afforestation and conversion of cropland to forest is based on the site preparation. Only scientific and standardized land preparation can only change the “three runs” of running water, soil running and running fertilizer into the “three episodes” of collecting water, collecting soil and collecting fertilizer To ensure afforestation and returning farmland to forest high survival, growth and high efficiency in order to achieve afforestation and the fundamental purpose of returning farmland to forest, otherwise, it is inevitable that the waste of money, more harm than good. First, what is the science of land preparation According to "water is the source of life, soil is survival
