Rice cultivation and management, water is classified as water, fertilizer, gas, hot first four major elements. Well managed, can water to regulate fertilizers, gas, temperature control, to create a good physiological and ecological environment, to promote the aboveground and underground parts of rice, vegetative and reproductive growth and coordinated development; poor management, leading to stagnation of growth, development Blocked Therefore, good or bad tube water is able to seize the key to high yield and high yield of rice.
