Problems solved by technology

Bare root seedlings (full seedling weight about 2kg) are used to colonize the forest section when the rubber tree is cut and dried out of the nursery. The survival rate of the colonization is affected by the weather conditions and the cultivation techniques of the planters. It is also less than 80%, and it needs to be replanted many times, which will affect the uniformity of the forest
The root control device is combined with the corresponding seedling substrate to grow seedlings, which can shorten the seedling cycle (up to 50%), reduce nursery labor (about 50-70%), increase the number of roots (up to 30 times), and facilitate planting compared with conventional seedling bag seedlings. , used in some landscaping, valuable tree species and high value-added seedlings, but little research and application in rubber tree seedlings

Embodiment 1

[0024] The present invention cultivates the seedling raising method of large-scale full canopy seedling of rubber tree, comprises the following steps:

[0025] (1) Container selection: Choose a porous root control device made of PVC and polyethylene composite material. The porous root control device is a cylindrical seedling container composed of a surrounding planting plate and a chassis composed of small protrusions with concave and convex side walls. When assembling, pay attention that there will be no small One end of the hole is placed on the top, which is convenient for water storage after watering, and the side with the small hole on the side wall is placed outside, which is convenient for root control by using the principle of air pruning; the size of the porous root control seedling container is 20cm in diameter and 30cm in height ;

Abstract

The invention discloses a seedling raising method for cultivating large-scale full crown seedlings of rubber trees. The seedling raising method includes the steps of container selection, embryo seedling selection, base material selection, nursery caressing and seedling hardening and planting. The large-scale full crown seedlings of rubber trees are adopted for planting, the labor for nurturing ina non-production period is reduced, the competitiveness of the rubber seedlings in the non-production period is improved, the non-production period is shortened, and the rubber trees are allowed to enter a cutting-available period 1-3 years earlier than conventional planting. By adopting the method, the seedling raising cycle is short, the cost is low, the seedling quality is good, the planting efficiency and survival rate are high, the rubber tree planting time can be enriched, the problem of forest irregularity caused by replenishing seedlings after planting is solved, the adverse effects ofweeds or intercropping crops on the rubber tree seedings in the non-production period are reduced, a new choice is provided for rubber tree seedling planting materials, the seedling raising method issuitable for planting on relatively flat woodlands or sloping fields, the full stand keeping rate of the rubber tree seedlings after planting of the rubber tree seedlings can be increased, and the cost of nurturing during the non-production period is reduced.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a seedling raising method, in particular to a seedling raising method for cultivating large-scale full-canopy seedlings of rubber trees. Background technique [0002] Large-scale rubber tree seedlings, such as high cut-off seedlings, are cut-off seedlings with a stem length of about 2.5m (at a height of 100cm above the ground) with a stem circumference of more than 8cm and have been corked. Such seedlings retain the growth of more than one year in the previous period , strong stress resistance, good for overwintering, can reduce livestock damage, suitable for supplementing and replanting materials, and can also be used for small-scale planting, which can shorten the non-production period. The rubber garden established with large seedlings is neat, and when the rubber tree is cut It has the advantages of high cutting rate, but it needs time-consuming and complicated root pr...
