泡桐由于生长快,材质好,胁地少,颇受群众欢迎,已成为川塬地区“四旁”绿化的主要树种之一。但在渭北高原,常因春季低温、干旱,夏秋强度蒸发,而使埋根育苗出苗差、保苗难、成苗少、出圃慢(需二年出圃),不仅影响绿化进程,也造成了土地、种根、人力和资金的浪费。为了解决这个问题,1982年春,我们在蒲城县党木公社党南一队和县林科所实验苗圃,设置了泡桐埋根育苗地膜覆盖试验。1983年又在县林科所实验苗圃及翔村、苏坊、党木、平骆、荆姚等地布置泡桐埋根地膜覆盖育苗11亩,进行重复试验,效果很好。现将试验情况简报如下。一、试验材料和方法1.种根:1982年所用种根,系从河南、渭南调入的兰考桐根。埋前进行温床催根处
Paulownia growth due to fast, good material, less threatening, quite popular, has become the Sichuan “highland” green one of the main tree species. However, in the Weibei Plateau, due to the low temperature, drought, summer and autumn intensity of spring evaporation, the seedling emergence of buried roots is poor, seedling is difficult, seedlings are less, and grow slowly (take two years to nursery), not only affect the process of greening, but also caused the land , Rooting, waste of human and financial resources. In order to solve this problem, in the spring of 1982, we set up the mulching test of Paulownia seedling rooted nursery in the south first team of Party Wood Commune of Pucheng County and experimental nursery of Linkeke County. 1983 again in the county Linke experimental nursery and Xiangcun, Su Fang, Dangmu, Pingluo, Jing Yao and other places planted Paulownia mulching mulching 11 acres, repeated testing, the effect is very good. Now the test briefings are as follows. First, the test materials and methods 1 kinds of roots: 1982 kinds of roots used, from Henan, Weinan transferred Lantau root. Buried before the hotbed of the root cause
