Biological water-saving technology of rice
Biological water saving technology refers to the use of the physiological and genetic potential of organisms to obtain more output under the same water conditions. Although the research is difficult and the degree of development is low, the investment in the application is small and the benefit is high. Using a large number of germplasm resources obtained for many years, rice breeders selected a number of varieties with strong drought resistance by means of inter-variety hybridization, systematic breeding and introduction and evaluation, and applied genetic engineering to the breeding of new varieties. continue to provide new hybrid rice combinations with high quality, strong drought tolerance and greater biological potential for water-saving cultivation.
