Said agriculture minister Han Changfu 5 in the national NPC and CPPCC minister channel to answer a reporter's question, in recent years Chinese grain harvest year after year, the grain yield for 5 consecutive years stable at 1 trillion and 200 billion pounds on the steps, the use of chemical fertilizers has a significant effect on the grain growth, but can not say "hello" out of fertilizer. In 2017, China use of fertilizer to achieve a negative growth, three years ahead of schedule to achieve the "13th Five-Year" goal is to measure the use of chemical fertilizers and pesticides zero growth.

"Chinese jobs firmly in our own hands." Han Changfu said, grain yield Chinese has reached a very high level, China has a population of 10 million, the food is always a top priority for the country, the government work report specifically mentioned, the grain production capacity reached 1 trillion and 200 billion pounds, in the next few years, will continue to stabilize and optimize the grain production.

For fertilizer in the important role of grain production, Han Changfu said yes, but he stressed that food production by chemical fertilizer can not say "hello" out of the. Since the reform and opening up, China's grain output has reached 1 trillion and 200 billion jin from 600 billion kilograms in the year. First, it depends on policy, two by science and three by investment. Another well-known saying is: "policy is good, people work hard, and days help". Many factors, such as improved seed production, technology and agricultural mechanization, play a role in increasing production.

"The next step, the agricultural sector should vigorously promote the development of green agriculture", Han Changfu said, will continue to promote the reduction of fertilizer efficiency.
