Rootstock cultivating method and plant grafting method

Abstract

The invention provides a rootstock cultivating method and a plant grafting method, and relates to the technical field of crop growing. The rootstock cultivating method comprises the steps of sowing seeds of a rootstock; spraying a polyploidy inductive agent on the seedlings of the rootstock after the seeds of the rootstock sprout. According to the rootstock cultivating method, by spraying the polyploidy inductive agent on the seedlings of the rootstock, the rootstock no longer continues to grow according to the regularity in itself, and a good basis is established for the grafting of other plants. In addition, the plant grafting method comprises the steps of sowing seeds of the rootstock and seeds of a cion respectively; spraying trifluralin on the seedlings of the rootstock after the seeds of the rootstock sprout; grafting the seedlings of the cion to the seedlings of the rootstock. According to the plant grafting method, by spraying the trifluralin on the seedlings of the rootstock and then conducting grafting work, the situation that the rootstock grows and reproduces according to an original regularity in itself is effectively inhibited, the rootstock can provide more nutrition for the growth of a grafted plant, and crop yield and disease resistance of the grafted plant are strengthened.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a rootstock cultivation method and a plant grafting method. Background technique [0002] During the cultivation of crops, in order to better meet the needs of humans for crops, it is often necessary to graft the scion onto the rootstock, which can provide the required nutrients and moisture for the growth of the scion and maintain the normal growth of the scion. [0003] Yet rootstock itself also maintains certain growth, after scion is grafted on stock, rootstock can still absorb nutrition for self germination growth, and the new shoot of rootstock can capture the nutrition of scion to a certain extent, thereby slows down the growth of scion. Growth, therefore just need the new bud of pruning stock regularly, not only needs to consume more labor, wastes time and energy, and, also can hinder the growth of scion, affects the output of scion crop. Therefore, there is a n...

[0003] Yet rootstock itself also maintains certain growth, after scion is grafted on stock, rootstock can still absorb nutrition for self germination growth, and the new shoot of rootstock can capture the nutrition of scion to a certain extent, thereby slows down the growth of scion. growth, therefore it is necessary to regularly prune the new shoots of the rootstock, which not only consumes more labor, is time-consuming and laborious, but also hinders the growth of the scion and affects the yield of the scion crop.
