泡桐是我区速生用材、农林间作和四旁绿化的主要树种,在林业生产中占有优势地位。近几年来,泡桐发展很快,1983年全区泡桐育苗面积达4万余亩。我区不少地方人多、地少,苗、粮用地的矛盾比较突出,特别是当前农村大秋地少,林木育苗地更显得不足。为了提高苗木出圃率和充分发挥土地潜力,提高复种指数,增加单位面积产值,探索苗粮双丰收的途径,1983年在中国林业科学研究院泡桐组、省林技站、地区科委的大力支持和配合下,我们与有关单位协作,在立地条件不同的商丘、柘城、睢县、民权等地设点,进行了麦茬地移栽泡桐育苗试验,大部分试验成功,当年出圃造林。现将商丘县平台点的试验简介如下:
Paulownia is a fast-growing timber in my area, between the agro-forestry and greening around the main tree species, occupies a dominant position in the forestry production. In recent years, Paulownia developed rapidly in 1983 Paulownia nursery area of more than 4 acres. In many areas of our region, there are many places where there are fewer people and less land. The contradictions between land use and land for grain use are quite prominent. In particular, at present, there are few big autumn and fall areas in rural areas and the shortage of tree nurseries is even more apparent. In order to improve the rate of nursery stock and give full play to the potential of the land, raise the index of multiple cropping, increase output value per unit area and explore ways of double harvest of seedling and grain, in 1983, the strong support of Chinese Academy of Forestry Paulownia group, provincial forestry station, In cooperation with the relevant units, we set up sites in Shangqiu, Tancheng, Juxian, civil rights and other places with different site conditions to carry out transplanting Paulownia nursery experiments on wheat stubble field. Most of the experiments were successful. Now Shangqiu County platform test briefings are as follows:
