Embodiment Construction

[0033] In order to make the objectives, technical solutions and beneficial effects of the present invention clearer, the technical solutions in the present invention will be further described below in conjunction with examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] The invention provides a screening method for corn bacterial wilt resistant plants, the screening method for corn bacterial wilt resistant plants is carried out in a solar greenhouse, characterized in that the screening method comprises:

[0035] Preliminary preparation: One week before sowing, turn the soil to the first depth, dry the soil, and sprinkle plant ash at a rate of 150-300 kg / mu; then rake the soil layer and level it, and set up ditches at intervals of one furrow and one furrow Lay ridges with a width of 50-80 cm; lay water spray pipes in the ditch, and lay film on the ridge after f...

Abstract

The invention provides a screening method of corn bacterial wilt resistant plants. The screening method comprises the following steps of early-stage preparation; a first culture stage; a bacterial wilt induction culture stage; and a second culture stage. According to the method, corn plants are cultured by adopting a specific culture environment, so that screening of the corn bacterial wilt resistant plants is not limited by uncertain natural environment factors such as seasons, sites and the like any more, and resistant materials of corn bacterial wilt can be screened out more accurately andefficiently.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a screening method for maize bacterial wilt resistant plants. Background technique [0002] Bacterial wilt is a soil-borne disease. Because its occurrence is mainly affected by the climate, its occurrence is rapid and its control by drugs is very difficult, making bacterial wilt the most important disease in corn production, which brings great benefits to the development of the corn industry and the arrival of a new agricultural era. Big threat. [0003] There are two types of symptoms after the onset of bacterial wilt: one is the bacterial wilt type, and the course of the disease develops rapidly, which is an acute type of symptom; generally, after the corn enters the stage of milk maturity, the root system and stem base become brown, soft and water-stained , or light brown rot, observed from the longitudinal section, the first aboveground node of the stem base ...
