关中麦田綠肥草木樨巳在灌区推广,但灌区复种指数較高,綠肥的发展受到一定的限制。旱地小麦多为歇茬栽培制,夏閑地多,且肥力不足,有进一步培肥的必要。我省陝北地区年降雨量在400毫米左右,草木樨生长很好。关中年降雨量500~700毫米之間,旱地种植草木樨綠肥是可能的。但旱地水分毕竟不够充足,草木樨綠肥在关中旱地的发展前途如何?的确还須通过較长的研究和生产实践的考驗良能作出比較客覌的估
Guanzhong wheat field green manure has been promoted in irrigated areas, but the index of multiple cropping in irrigated area is higher, and the development of green manure is limited. Dry wheat is more intermittent cultivation system, more summer fallow, and lack of fertility, there is a need for further fertilization. The annual rainfall in northern Shaanxi Province is about 400 millimeters and the growth of vegetation is very good. Mid-year rainfall of 500 to 700 mm, the dry land to plant vegetation green manure is possible. However, after all, the water in the drylands is not sufficient enough. What is the future development of vegetation and green manure in the Guanzhong upland? It is indeed necessary to make a comparative assessment based on long-term research and production practices
