Abstract: Molecular markers linked to main QTL for regulating resistance of rice to whitebacked planthopper are provided. The QTL is located on rice chromosome 1, with a genetic distance of 30.88-34.32 cM and a physical distance of 7203302-8007653 bp. Then the molecular markers are set on both sides of the QTL, and the molecular markers are used to screen rice varieties resistant to whitebacked planthopper, which improves the selection efficiency of ideal plant types of rice.

Abstract: In one embodiment, a method includes generating, from an accessed image, one or more image patches, and for each image patch: (1) accessing a set of point-spread functions (PSFs), wherein each PSF in the set of PSFs corresponds to one of a plurality of points in the image patch; (2) generating a set of deconvolved image patches by deconvolving the image patch with each PSF from the set of PSFs for that patch; (3) determining, for each of one or more portions of the image patch, a set of weights, wherein each weight in the set of weights is associated with one of the deconvolved image patches; and (4) generating a restored image patch by interpolating the set of deconvolved image patches based on the set of weights.

Abstract: The present disclosure provides a joint control method for nitrogen and phosphorus emissions in farmlands, comprising: reducing nitrogen and phosphorus input during crop sowing or planting by applying composite organic material and chemical fertilizer, wherein the composite organic material comprises: 200-250 parts of edible fungi residues, 300-350 parts of charcoal and 5-10 parts of rhamnolipid; constructing a nitrogen-phosphorus retention layer by utilizing composite microbial agent in combination with 150 parts of edible fungi residues and 20 parts of straw-based hydrogel; constructing a barrier layer by utilizing composite material, and controlling downward leaching of nitrogen and phosphorus that are not absorbed by crops, wherein the composite material of the barrier layer comprises: 25-35 parts of straw-based hydrogel, 20-30 parts of edible fungi residues, 35-55 parts of bentonite and 5-10 parts of corn flour.
