田菁又名“拔碱蒿”,顾名思义,说明它能耐盐碱。其实,要说它的抗逆性格,又何止这一点呢?它在耐旱、耐涝、耐瘠薄等方面,是所有绿肥中首屈一指的。所以,田菁是淮北黄泛平原改良盐碱地的先锋作物。近二年来,上海郊区每年从外地引进田菁种子,作为套夹种夏绿肥,这对增加土壤有机质,改良土壤和争取稻棉双高产是一项很有意义的工作。但是,上海郊区由于引种年限较短,经验不足,有待于进一步试验研究,不断总
Tian Jing, also known as “drawn alkaline Artemisia,” as its name implies, shows that it can tolerate salt. In fact, to say its resilience, not to stop this? It is drought-resistant, waterlogging resistance, infertility, etc., is second to none in all green manure. Therefore, Tian Jing is the pioneer crop of saline-alkali land in Huaibei Yellow River Plain. In the past two years, the suburbs of Shanghai have introduced the seeds of Sesbania from the outside world each year as a summer green manure. This is a significant task for increasing soil organic matter, improving soil and striving for double-high yielding rice and cotton. However, due to the short introduction period of Shanghai suburbs, lack of experience to be further experimental studies, the total
