Problems solved by technology

The main problems of this method are: plugging has strong technical requirements and requires professional operation. It is extremely difficult for ordinary people to get started, and the work efficiency is low. Human operation has a great impact on the survival rate.
The main problem of this method is: compared with other grafting methods, it is cumbersome and requires both rootstock and scion to be pulled out, and then replanted after grafting. The grafting efficiency is low. Part, the grafting interface is not easy to fully fuse, and it is difficult to support the weight of the whole pepper in the later stage and break
The main problems of this method are: the environmental requirements of the seedbed during the survival of grafted seedlings are relatively strict, the survival rate of grafted seedlings is greatly affected by the level of management, the survival rate is not easy to grasp, and the interface of split grafted seedlings is prone to splitting
[0006] For the above three grafting methods, plugging has high technical requirements for operators, and the other two cutting surfaces are not easy to completely merge, which brings great difficulties to management after grafting. Yield

Embodiment 1

[0021] In June 2015, at the experimental base of Huaiyin Agricultural Science Institute in Xuhuai District, Jiangsu Province, eggplant "Torubam" and pepper rootstock "Graft" were selected as rootstocks, and pepper "Xianhong No. 1" was used as scion for grafting. Contrast experiment, the grafting method that adopts in the parallel experiment is the method that the present invention provides, each grafting method three people each graft 72 strains, 18 days after grafting count the survival rate of different grafting methods.

[0022] 1. Synchronous selection, sowing and management of rootstock

[0023] Select eggplant special rootstock "Torubam" and pepper rootstock "Graft", soak the seeds with 100mg / kg gibberellin solution for 24 hours, and then wash them with water for later use.

[0024] rootstock seeding substrate

[0025] The volume ratio of cassava residue: peat: vermiculite: perlite is 4: 4: 1: 1, the bulk density of the seedling substrate is 0.37, the porosity is 81%, t...

Embodiment 2

[0051] In August 2015, grafted seedlings of "Tuolubamu-Xianhong No. 1", "Graft-Xianhong No. 1" and "Xianhong No. The self-rooted seedlings of "Red No. 1" were investigated and tested on root rot and pepper blight. The selected fields are pepper continuous cropping fields, and the normal incidence rate of root rot is about 10-15%.

[0052] Three groups were designed for the experiment, CK was the self-rooted seedlings of the scion "Xianhong No. 1", T1 was the rootstock of "Graft", and T2 was the rootstock of "Torubum". Three plots were designed for each group and a total of 3 repetitions were designed. Random block group Arranged, and planted 20 seedlings in each plot, with protective rows around them. Carry out normal pepper cultivation and management, and manage the same period in all plots. After 2 months, mainly investigate the incidence of root rot and other diseases.

Abstract

The invention discloses a capsicum grafting seedling cultivation method taking an eggplant tree as a stock. According to the method, an eggplant tree stock is cultivated, a crapsicum scion is cultivated, grafting and grafted seedling management are carried out, a transplanting seedling is formed, during grafting, a two-true-leaf portion at a bottom portion of the eggplant tree stock is cut upwards by a blade in a direction of 45 DEG; a two-leaf portion below the top portion of the crapsicum scion is cut downwards in a direction of 45 DEG, diameters and cutting faces of the stock and the crapsicum scion basically fit; the cutting faces of the scion and the stock are rapidly applied and fixed to accomplish seedling grafting. Through the capsicum grafting seedling cultivation method taking the eggplant tree as the stock, the survival rate is relatively high, disease resistance of the eggplant tree stock is applied to the capsicum growth, so the method has wide application prospects for factory seedling growth.

Description

technical field [0001] The invention relates to the field of cultivation of grafted pepper seedlings, in particular to a method for cultivating grafted pepper seedlings using eggplant as a stock. Background technique [0002] At present, the cultivation of grafted pepper seedlings mainly uses peppers as rootstocks, and there are plugging methods, leaning methods and splitting methods, and the operation methods are as follows: [0003] The grafting method, generally 20-30 days after sowing, is suitable for grafting when the rootstock has about 5 true leaves. The pepper scion seedlings should have 1-2 leaves less than the rootstock seedlings, and the seedling stems are slightly thinner than the rootstock seedling stems. When grafting, cut off the axillary buds on the top of the second true leaf of the rootstock, and use a bamboo stick with the same thickness as the scion to insert obliquely downward at an angle of 45-60 degrees on the leafless side of the top, and the length o...
