箭筈豌豆(Vicia safiua L.)是一种肥、饲、粮兼用作物,在我国种植范围广达新疆、青海、江苏、台湾等20余个省区(洪汝兴等 1985)。在我省的种植面积已扩大到50万亩之多,是重要的绿肥和饲草作物之一。随着箭筈豌豆的广泛种植,人们开始注意到锈菌(Uromyces orob Lev)是该作物的一个重要病害。但有关其对箭筈豌豆影响的报导,尚未有过。鉴此,笔者探讨了感染锈病的箭筈豌豆在生长、根瘤及营养成分含量等方面的变化,旨在为深入研究该病及合理利用作物,提供某些参考。一、取样方法
Vicia safiua L. is a kind of fertilizer, feed and grain-crops. It has been planted in China in more than 20 provinces and autonomous regions including Xinjiang, Qinghai, Jiangsu and Taiwan (Hong et al. 1985). The planting area in our province has been expanded to more than 500,000 mu, which is one of the important green manure and forage crops. With the widespread planting of arrowhead peas, it is noticed that Uromyces orob Lev is an important disease of the crop. However, there have been no reports of the impact on the arrowhead peas. In view of this, the author discusses the rust-infected arrowhead pea growth, nodulation and nutrient content changes, designed to further study the disease and rational use of crops, provide some reference. First, the sampling method
