泡桐是我省农桐间作、四旁和城市绿化的主要速生用材树种,近年发展很快,育苗面积逐年增加,1982年全省泡桐育苗面积已达30多万亩.为解决和减轻育苗和粮食争地的矛盾,我们于1980-1982年在安阳县天喜镇公社三仓大队的冬小麦地进行了泡桐埋根育苗试验.当年苗高3.79米,地径5.85厘米,亩产成茁570株,出圃率72.4%.小麦亩产372斤、大豆112斤,和对照地比较,亩木和小麦产量均无明显差别.而经济效益十分显著,总产值平均比对照地提高3.88-6.42倍.为便于生产上应用,现将试验情况总结如下,以供参考.一、试验地自然概况试验地属太行山东麓丘陵河谷台地,
Paulownia is the province of Agropyla roxburghii, around the city and greening the main fast-growing timber species, the rapid development in recent years, nursery area increased year by year, the province Paulownia nursery area has reached more than 300000 acres.In order to solve and reduce nursery and food disputes In 1980-1982, we carried out the experiment of embedding seedlings of Paulownia trees in the winter wheat fields of the three positions of Tianxi Town Commune in Anyang County from 1980 to 1982. The seedling height was 3.79 meters and the soil diameter was 5.85 cm, yielding 570 plants per mu The rate of 72.4% .Every wheat yield 372 pounds, 112 pounds of soybean, compared with the control, no significant difference in the output of mu and wheat, while the economic benefits are very significant, the average output value increased by 3.88-6.42 times on average .In order to facilitate the production On the application, the test is summarized as follows, for reference.First, the experimental nature of the test is located in the foot of the Taihang Mountains hilly valley platform,
