千里光学名田皂角,又名合萌、水松柏。我们于1973年开始试种,经过五年观察试验、示范推广,证明千里光是一种适应性广,水生速生的夏季好绿肥。产量高,撒播的一个月后亩产鲜草3,000斤以上;育苗移栽套种的亩产1,500斤。肥效长,含氮量3.3%,五氧化二磷0.65%,氧化钾0.64%,压青后肥效可持续到第二年早季。生物学特性千里光为一年生豆科植物,根茎中空,密生根瘤和茎瘤,根瘤形园而小,色白,茎瘤扁绿色,瘤汁紫红。根瘤随水层高低而移动,特别在水层处茎瘤特多,
Celestial optics field saponin, also known as Moe, water cypress. We started trial planting in 1973. After five years of observation and experiment, demonstration and promotion, we proved that Senecio is a good summer green manure with wide adaptability and rapid aquatic life. High yield, sowing a month after the yield of fresh grass more than 3,000 pounds; seedling transplanting interim planted 1,500 pounds. Fertilizer efficiency, nitrogen content of 3.3%, phosphorus pentoxide 0.65%, 0.64% potassium oxide, after pressing the pressure of fertilizer can last until the second year in the early season. Biological characteristics Trinidad light for the annual legumes, rhizome hollow, dense root nodules and stem tumors, nodular garden and small, white, stem flat green, tumor juice purplish red. Nodules with the level of the water layer and move, especially in the water layer at the stem tumor,
