Abstract: A drain pan and an air conditioner are provided. The drain pan includes a plastic member and a foaming member, an air outlet near the edge of the plastic member, and a water receiving sink. An air inlet is provided in the middle part of the plastic member. The water receiving sink is arranged between the air inlet and the air outlet and surrounds the air inlet. The air outlet continuously surrounds at least part of the outer edge of the water receiving sink. Multiple supporting grilles are arranged inside the air outlet. The supporting grilles are distributed at intervals in an extension direction of the air outlet. The foaming member and the plastic member at least partially overlap with each other. The foaming member avoids the air inlet and the air outlet.

Abstract: A heat exchanger sealing plate for an air conditioner, an indoor unit and an air conditioner are provided. The indoor unit includes a casing, an air guiding ring, a heat exchanger, a sealing plate and a water pump. The air guiding ring is provided in the casing. The heat exchanger has a first end and a second end, and the heat exchanger is provided in the casing and surrounds the air guiding ring. The sealing plate is provided in the casing, the sealing plate has a first connecting portion, a second connecting portion and a water pump mounting portion. The first connecting portion and the second connecting portion are connected to the heat exchanger, in order for the sealing plate to close a gap between the first end and the second end of the heat exchanger. The water pump is mounted on the water pump mounting portion.

Abstract: The present application discloses a plant senescence accelerator named IDL7 mature polypeptide, and its preparation method and an application thereof. The application belongs to the field of a plant senescence accelerator, and the IDL7 mature polypeptide serves as a major functional ingredient with the following amino acid sequence: F-G-S-L-V-L-N-A-L-P-K-G-S-R-P-G-S-G-P-S-K-K-T-N. The IDL7 mature polypeptide plant senescence accelerator may promote the leaf senescence of plants without other additional adverse manifestations, thus this application has strong field operability.

Abstract: The present application an IDL6 mature polypeptide plant aging promoter, and a preparation method and application thereof, belonging to the field of plant aging promoters. The IDL6 mature polypeptide plant aging promoter is with an IDL6 mature polypeptide as a main functional component, and the IDL6 mature polypeptide having the following amino acid sequence: F-G-S-L-V-L-N-A-L-P-K-G-S-V-P-A-S-G-P-S-K-R-I-N. The provided plant aging promoter can promote the leaf senescence of the plant, accelerate the senescence, and has no other additional bad performance, and has extremely strong field operability.

Abstract: The present application provides an application of quercetin in a plant senescence accelerator, which belongs to the field of plant senescence accelerators and its application, and can prepare a plant senescence accelerator by using quercetin and apply the accelerator in practical production to accelerate the senescence process of plant particularly crop leaves. The quercetin plant senescence accelerator is prepared by mixing a quercetin mother solution with a 1/2 MS solution of 2-(N-morpholino)ethanesulfonic. In the present application, by adopting directly spraying method, the senescence process of plant leaves can be accelerated, and will not cause additional adverse reactions to plants.
