Detailed Introduction to Biological Water-Saving Technology in Rice

Biological water-saving technology refers to the use of a plant's own physiological and genetic potential to obtain more output under the same water conditions. Although it is difficult to research and remains underdeveloped, it requires little input and yields high benefits in practice. Using the large amount of germplasm resources obtained over many years, rice breeders have developed a number of strongly drought-resistant varieties through intervarietal hybridization, systematic selection, and introduction and evaluation, and have applied genetic engineering to the breeding of new varieties, continuously providing high-quality, strongly drought-resistant new hybrid rice combinations and new varieties with greater biological potential for water-saving cultivation.
