地膜覆盖技术,六十年代开始应用于园艺生产实践,起到促进生长,提高产量的效果。施肥在苗木培育中的地位愈来愈被人们所重视,成为培育优质苗木的有利措施。而同时采取覆盖地膜和施肥两项技术措施,多方面改变环境条件,对苗木生长产生的影响如何,至今很少见报道。为此,我们对黑枣(Diospgros lotus Linn.)育苗,进行了这方面的试验研究。试图通过覆地膜和施肥两项措施的结合,改善苗木生境,达到快速、优质培育壮苗的目的。经两年的试验,取得一些效果。
Film mulching technology, applied in the 1960s, horticultural production practices, play to promote growth, increase production results. Fertilization in the nursery stock raising more and more people’s attention has become a favorable measure to nurture high-quality seedlings. At the same time to take two technical measures covering mulching and fertilization, many changes in environmental conditions, the impact on seedling growth, so far rarely reported. To this end, we conducted a pilot study on the breeding of Diosprospea lotus Linn. Trying to improve the seedling habitat through the combination of the two measures of film mulching and fertilization, so as to achieve the purpose of cultivating seedlings quickly and with good quality. After two years of testing, achieved some results.
