泡桐育苗一般采用埋根法。为扩大新品种的繁育速度和满足生产的需要,我们对繁殖方法作了探讨。自1963年以来,我们采用兰考泡桐苗干的不同部位和长度进行育苗试验。近两年来为进一步提高生根率试用植物生长调节剂和化学药剂处理茎干,取得明显效果,现将试验报告如下。一、试验地概况试验地设在百泉农专实习苗圃。地势平坦,面积2亩。褐色土,pH值7.5,地下水位2米,中等肥力,前茬为棉花泡桐间作和杨树圃地,有少量蛴螬、地老虎等地下害虫。
Paotonguai seedlings are generally used to root method. In order to expand the breeding speed of new varieties and meet the needs of production, we discussed the breeding methods. Since 1963, we conducted nursery trials using different parts and lengths of Paulownia tomentosa seedlings. In the past two years to further improve the rooting rate trial of plant growth regulators and chemical treatment of stems, and achieved significant results, the test report is as follows. First, to test the general situation Experimental site located in Baiquan Agricultural practice nursery. Flat, an area of 2 acres. Brown soil, pH value of 7.5, groundwater level of 2 meters, medium fertility, the former crop of cotton Paulownia intercropping and poplar garden, a small amount of scabies, tigers and other underground pests.
