Method for grafting monocotyledonous plant corn and dicotyledonous plant mung bean

Abstract

The invention provides a method for grafting a monocotyledonous plant corn and a dicotyledonous plant mung bean. The method comprises the following specific steps: soaking seeds: soaking a disinfected corn seed for 24-25 hours and soaking a mung bean for 12 hours; germinating: germinating the soaked seed and maintaining the temperature at 20-25 DEG C; adding water into 3 / 5 of soil and 2 / 5 of seed breeding organic matter by using a seed breeding cup and uniformly stirring for later use; grafting: cutting off a corn germ from the lower part of an embryo section, cutting off the mung bean from a rooting point, inserting from the position of the cross section of the corn germ by using a wooden stick, enabling a mung bean scion to be in fit with a corn rootstock cutting surface and fixing the mung bean scion and the corn rootstock cutting surface through the wooden stick, wherein the depth is 0.8-1 cm; putting a grafted seedling in the cup for accommodating the seed breeding organic matter for pre-culture and then surrounding by using disinfected sandy soil to preventing interface infection; and maintaining the temperature between 80-85 DEG C and transplanting the grafted seedling into a filed on a cloudy day or in the evening after five days of interface healing. A new variety of mung bean obtained through grafting by adopting the method provided by the invention is high in survival rate, high in yield and strong in disease and pest damage resistance.

Description

technical field [0001] The invention belongs to the technical field of grafting of agricultural plant varieties, in particular to a method for grafting monocot corn and dicotyledon mung bean. Background technique [0002] Grafting refers to cutting off a part of the buds or leaves of a plant and grafting them onto another plant to make them a new plant. The advantages of grafting can make the grafted plants grow and develop faster, flower and bear fruit faster, have a stronger ability to adapt to adverse environments, and can improve disease resistance. Difficulty of Grafting Survival From a botanical point of view, the closer the relationship between two plants, the easier it is to survive grafting, which is caused by the different tissues of the plants. The so-called affinity refers to the ability of the scion and the rootstock to be able to combine with each other because they are the same or similar to each other in terms of internal organizational structure, physiology...
