Root-control container seedling raising method for large seedlings of Zelkova serrata

Abstract

The invention discloses a root-control container seedling raising method for large seedlings of Zelkova serrata. The root-control container seedling raising method for large seedlings of Zelkova serrata includes selecting 5-8 years old large seedlings of Zelkova serrata, primarily trimming shoots and roots, planting the large seedlings with bare roots in root-control containers filled with substrate and field soil, setting up stands for supporting, and performing water and fertilizer management; the substrate is nutritional soil retted from manure with added miscellaneous materials, the miscellaneous materials are composed of one or combination of any of tree bark, saw dust, tree branch, fallen leaf, crop straw, peanut shell and waste mushroom log. Root-control container seedling raising has the advantages of high transplant survival rate, effective transplanting and the like, the root-control containers enable lateral roots to be thick and short without tangling roots, the defect of root tangling in conventional container seedling raising is overcome, total root amount is increased by 30-50 times, survival rate of the seedlings can reach more than 98%, and seedling raising cycle is halved.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a method for growing beech seedlings in a container with root control. Background technique [0002] With the deepening of urban and rural greening construction, greening projects including urban park construction, green passage construction, urban green space, etc. have more and more stringent requirements for construction quality. In addition to ensuring the survival rate, the construction unit requires certain landscape effects. It is required to transplant the whole crown of large seedlings to achieve immediate results. However, the traditional production method of greening seedlings is bare-root cultivation, which can only provide cut seedlings and half-capped seedlings. After transplanting, the seedling period is long, the survival rate is low, and the landscape effect is poor. "Big trees entering the city" were severely damaged after transplantation, affecting greening an...

Problems solved by technology

The traditional greening seedling production method is bare root cultivation, which can only provide cut seedlings and half-capped seedlings. After transplanting, the seedling period is long, the survival rate is low, and the landscape effect is poor.

"Big trees entering the city" are severely damaged after transplantation, affecting greening and ornamental effects, low survival rate, and waste of resources.
