What dialectical materialism and epistemology viewpoints did Yuan Longping embody in the research of hybrid rice?

Dialectical materialism: 1 Dialectical materialism holds that matter determines consciousness and has a dynamic effect on matter. Yuan Longping's noble sentiment of contributing to the motherland has established a correct consciousness of studying hybrid rice, which has played an important role in solving the problem of food supply shortage faced by our society, promoted the development of rice planting in China, and is conducive to the more stable development of society. The law is objective. Yuan Longping's research on hybrid rice is based on his reflection on the current situation of food shortage in China, insisting on the objective laws and reality of rational social development and seeking truth from facts. The basic goal of the research work is to increase the grain output from reality, which is conducive to the all-round development of rice planting in China. Epistemology: 1. Practice is the source of knowledge. Yuan Longping's correct understanding of hybrid rice comes from long-term exploration of farmland practice. Practice is the driving force of knowledge development. Strengthening the on-the-spot investigation of farmland in Yuan Longping will help deepen the understanding of rice variety reform, and then get a more scientific understanding of planting. Practice is the only criterion for testing the truth. Only through field research and practice can it be tested in the process of rice planting. Whether something new is correct or not reflects the correctness of planting hybrid rice scientifically in Yuan Longping. Practice is the purpose and destination of cognition. Yuan Longping's "Hybrid Rice Law" was put forward to better guide the cultivation of hybrid rice and promote the continuous progress of rural society and even the whole society. The condition and concreteness of truth reflect that the application scope of Yuan Longping's grain production theory is limited, and it needs to be deepened and innovated in actual planting. Promoting development embodies the scientificity and correctness of Yuan Longping's rice planting theory. 6. With the improvement of rice planting technology in China, rice planting reform will be more thorough and smooth, which reflects the correctness of Yuan Longping's people-oriented thought and hybrid rice planting theory.
