t Institute at the Chinese Academy of Social Sciences, said China
‘s agricultural sector was plagued by inefficient production practices for亚博娱乐线上娱乐平台会所品茶微信
many years, while annual output was highly susceptible to changes in climate.
For example, from 1959 to 1961 large parts of the country experienced a severe drought.亚博娱乐线上娱乐平台会所
In 1961, the arid conditions reduced the total crop yield by 61 million metric tons, a 30 percent fall from 1958.
Since the early 1980s, the central leadership has attached great significan
亚博娱乐线上娱乐平台会所ce to agricultural innovation. In 2015, investment in scientific and technological research reached 55 billion yu
an ($7.8 billion at today’s rates), compared with 720 million yuan in 1978, Du said.
According to the ministry, more than 96 percent of fields dedicated to the cultivation亚博娱乐线上娱乐平台会所品茶微信
of major crops, including rice, corn and wheat, are sown with high-yield, resilient species.
亚博娱乐线上娱乐平台会所A number of crop-breeding platforms that employ scientifically proven approaches-such as the use of “dwarf-st
erile” wheat, the “super rice” system and hybrid corn breeding-have been established to fast-t
rack improvements in edible crops and ensure the food supply is reliable and safe in the long term.
The wide application of modern farming techniques ha亚博娱乐线上娱乐平台会所品茶微信
s also helped farmers to raise yields and reduce damage to the environment.
At present, environmentally friendly methods are used to prevent and control pests on 56.7 mill
ion hectares under cultivation, accounting for 15 percent of the total area affected by such pests.
亚博娱乐线上娱乐平台会所Meanwhile, smarter use of pesticides in demonstra
tion areas has reduced the use of chemicals by 20 to 30 percent, the ministry said.
The use of fertilizers has been further contained as a result of a nationwide campaign l亚博娱乐线上娱乐平台会所品茶微信
aunched in 2005. It aims to tailor the use of synthesized fertilizers to suit local soil conditions
and improve awareness of the scientific management of fertilizers among farmers.
