Abstract: The present disclosure locates a new brown planthopper resistance gene BPH33.2 on the short arm of rice chromosome 4 by extreme mixed pool analysis (BSA-seq), and genetically transforming the gene BPH33.2 to make the susceptible rice to be the brown planthopper resistant phenotype rice; at the same time, the knockout of the gene BPH33.2 was used to cause the loss of the brown planthopper resistant phenotype in insect resistant rice, thus confirming the function of BPH33.2. The present disclosure also provides molecular markers closely linked with the rice brown planthopper resistance gene BPH33.2.

The method for treating high-calcium wastewater by calcification blocking includes mixing high-calcium wastewater, an alkalizing agent and a chelating agent, and carrying out alkalizing conditioning pretreatment under a condition of stirring by bubbling of a biogas, so as to obtain pre-conditioned wastewater. The pre-conditioned wastewater is mixed with anaerobic granular sludge, and an anaerobic reaction is performed in a high hydraulic shear flow field formed by the biogas, so as to generate the biogas and calcium scale. A part of the biogas for the stirring is refluxed by bubbling of the biogas and the rest of the biogas is refluxed for forming the high hydraulic shear flow field.
