泡桐实生苗虽具有多种优点,但因用常规育苗方法,用种量大,苗木生长慢,不能当年出圃。同时,随着科研和生产的发展,需要繁殖稀有、量少的优良泡桐人工杂交种子或天然种子,用常规播种方法亦不相宜。为了解决这些问题,1984年我们进一步进行了泡桐芽苗移栽地膜覆盖育苗试验,取得了良好效果,现将有关技术介绍如下。一、芽苗的培养从2月下旬开始,将准备好的种子,放在800倍退菌特溶液中,浸泡30分钟,捞出,用清水反复冲净,以防药害。再把消过毒的种子在常温下用水浸泡一昼夜,即可取出,
Although Paulownia seedlings have many advantages, but because of the use of conventional seedling methods, with a large amount of seedlings grow slowly, can not be out of nursery. At the same time, with the development of scientific research and production, it is necessary to breed fine paulownia hybrid seeds or natural seeds that are rare and in small quantities, which is not suitable for the conventional sowing methods. In order to solve these problems, in 1984 we further carried out Paulownia seedlings transplanted plastic film mulching seedling test and achieved good results, the technology is introduced below. First, the cultivation of sprouts from the beginning of late February, the seeds will be prepared on the 800 times the antibacterial solution, soak for 30 minutes, remove and rinse repeatedly with water to prevent injury. Then sterilized seeds soaked in water at room temperature for a day and night, you can remove,
