在天水地区,羣众栽培草木樨已近十年了,但較大面積的推廣,还是解放后5—6年内的事情。几年來,对草木樨的生物学特性及其作用,已有人在注意研究,曾先后發表过不少文章。在这里,我們將討論近几年來以草木樨应用到輪作里,在春作(或冬作)收穫后休閑期(6月下旬—8月下旬,此階段为水土流失最嚴重的季節)内对于增强植被,防止或減少冲刷和肥分流失,并獲得大量的叶綠体,增加土壤中的有机質含量,改变其物理性——化学性,借以
In the Tianshui area, people have cultivated plants and trees for nearly a decade, but the promotion of a larger area is still a matter of 5-6 years after the liberation. Over the past few years, the biological characteristics of grass mulberry and its role, people have been paying attention to research, has published many articles. Here, we will discuss the application of vegetation to the crop rotation in recent years. During the spring harvest (or winter crop) after harvest (from late June to late August, the most serious season for soil erosion) Enhance vegetation, prevent or reduce scouring and fertilizer loss, and access to a large number of chloroplasts, increase soil organic matter content, change its physical - chemical, by which
