| 摘 要： | 在晚季稻田自然生长条件下,观测野慈姑的生物学特性,研究其不同密度对移栽水稻产量影响,结果表明:晚季稻田耙平后约30 d野慈姑出苗达高峰期,历期约46 d;野慈姑绿叶和总叶数呈逐渐上升-稳定-下降的消长动态,新叶生长速度为每3d平均长0.5～0.8叶,新叶生长过程大致可分为3个阶段.不同生长期叶片平均长度、宽度分别为8....

| Abstract: | Biological characteristics of Sagittaria trifolia Linn.were observed in the fields of the late-season rice.Their effects on the rice yield were evaluated.Most S.trifolia seedlings sprouted 30 days after the late-season rice fields were plowed and leveled.The sprouting might last for 46 days.The numbers of green leaves and total leaves on the plant provided a quantifiable index for the weed growth.They increased,stabilized and decreased during the weed's lifespan,while the number of withered leaves always in... |
