Embodiment

[0014] Embodiment: adopt the method for raising seedlings of Ulmus chinensis with root buried strips of the present invention, (1) select mother plant: at the beginning of March, select the seedling of Ulmus chinensis with straight trunk and length more than 1.8 meters, and dig out with roots; (2) Treatment of the mother plant: select all the side branches on the side with a large amount of side branches, and cut off all the side branches on the other side; -0.15 meters to make a ditch, lay down the processed plants and bury them in the ditch. The buried root part is specially deepened by 9-12cm to bury all the roots. It is advisable to bury the main branch at a depth of 5-8cm; After the seedlings, the root of the next seedling is about 20-30cm away from the tip of the previous seedling for burying; after burying a row of seedlings, select side branches with a length of more than 30cm for burying; bend the branches when burying, Embed the branches in the direction of the verti...

Abstract

The invention relates to a new Ulmus pumila cv.jinye seedling raising technique, in particular to an Ulmus pumila cv.jinye root-reserved and branch-buried seedling raising method which has new breakthrough in breeding speed of the Ulmus pumila cv.jinye. The method is characterized in that 1. selecting all lateral branches at one side with large lateral branch amount of a plant while treating a maternal plant, and removing all lateral branches at another side; 2. performing primary branch burying, selecting branches with the length more than 30cm for burying, and burying branches with the length less than 30cm into soil with principal branches; and cutting 2-3 cuts at the lowest part of a bent part of the branches buried in the soil; and 3. selecting the branches with the length more than 30cm for secondary branch burying by new lateral branches growing in the primary branch burying and new branches growing on unburied branches in June; performing tertiary branch burying on the branches with the length more than 30cm, wherein, the branches grow into new plants in autumn; and the treatment method in the secondary branch burying and the tertiary branch burying are the same. The method has the advantages of high propagation coefficient, rapid propagation speed, less expense and low cost.

Description

technical field [0001] The invention relates to a new technique for raising seedlings of Ulmus chinensis, in particular to a method for raising seedlings of Ulmus chinensis with roots buried in strips, which has a new breakthrough in the breeding speed of Ulmus chinensis. Background technique [0002] Burying is a method of raising seedlings by laying the branches flat and burying them in the seedbed to promote germination and rooting. It belongs to asexual reproduction. This method also includes using rooted annual seedlings as seedling material to bury seedlings, which is called the method of burying seedlings (burying trees). The disadvantage of adopting the traditional technique of burying strips with roots is that the reproduction coefficient is low, and the cultivation of a seedling of Ulmus chinensis with traditional techniques can only cultivate 5-8 seedlings a year. Ulmus chinensis seedlings can also be raised by grafting, but the grafting process is complicated, t...
