The security of China's edible oil supply is seriously threatened by more than 60% dependence on imports

"
I am most worried about, is that more and more farmers because of the loss no longer plant rape, and finally we Chinese'soil bottle
'
but in the hands of foreigners.
"
every time I meet Wang Han, as long as chat about rape, usually smiling at him, will unconsciously
"
frowns
"
., chief scientist of the National Rape Industry System and director of the Oilseed Institute of the Chinese Academy of Agricultural Sciences.reporter recently obtained two sets of data, confirmed Wang Han's

sa sad
" -China's annual consumption of edible vegetable oil has now exceeded
3
0 million tons, but domestic edible vegetable oil production is Perenn year hovering at about
10 million tons
per year, resulting in China's edible vegetable oil self-se ratio of only about
40%
,
60%
or more dependent on imports, a serious threat to the national edible oil supply security.traditional rape production (artificial live planting), seeds, pesticides, fertilizers and other materialization costs per acre about
185
yuan, labor costs (
10
workers) per acre about
800
yuan, the total production cost per acre
9 85
yuan; according to the traditional production of high-yielding level of
180
kg per mu, per kilogram of rapeseed
5,
yuan, income per acre
900
yuan

;"
consequences, so that more and more farmers give up growing rape!
"
Wang Han in a number of occasions so anxiously
"
shouting
"
., however, one day in
mid-
, in Jingzhou City, Hubei Province, the public security county of Zhuyuan Town, the reporter again saw Wang Han, therape expert
"
locked eyebrows finally opened
-
this day, he and his team spent many years of hard work, research and development to promote the whole process of mechanized and efficient production mode of rape, in the town of Zhuyuan million mu of rape demonstration area aappearance
"
, won a cheer.'s excitement Lao He, a farmer in guanyin Temple Village in the town of Zhuyuan, has been working in the city for two years because of the loss of rapeseed. On this day, he came to the head of the ten thousand mu rape demonstration area early in the morning, and many villagers, listening attentively to the agricultural experts explain the whole process of mechanized and efficient production mode of rape composed of
9
technologies.
15
days before the harvest of rice, the rice field drainage dried, rice after harvesting
3 to 5
days, the use of joint seeding machine to rush seeding, trenching, fertilization, coverage, late drainage to be smooth. In this way, the seeding rate can be increased by
20% to 25%
, the seedling situation is still neat, the long-term trend can not be wrong.
experts
The Jingzhou Academy of Agricultural Sciences patiently introduced the soil-suitable management techniques. In addition, mechanized varieties, density control, slow release of full nutrition once fertilization, joint mechanical seeding, pre-bud closed weeding,
"
1 to promote four prevention
"
, mechanical harvesting and rapid decorrosity of straw and other technologies, but also by experts to the villagers who came to the news one by one. Canola head, rape seeder, low-altitude spray remote control aircraft, combine harvester, segment harvester, fully automated rotary tiller row, a low-altitude spray remote control aircraft, flying back and forth over rape fields to demonstrate, not far away, several harvesters are making a roar.Wang Han told reporters that the

rape process mechanized efficient production mode
"
research, mainly for China's rape mechanized production of low degree of technology integration bottlenecks, varieties, cultivation, soil fertilizer, plant protection, machinery and other advantages of technology, products and equipment, such as
9
individual technology integration, and to farmers to demonstrate the introduction."
tired day, a person will also collect an acre of land, with a harvester, ten minutes on the line!
"
Lao He sees it really. Ouyang Dunjun of Jingzhou Academy of Agricultural Sciences, who deals with farmers in the ground all year round, told Lao He that the harvester can also crush rape straw in place when working, and spray compound biobacterial agents to accelerate the decay of straw, improve soil fertility, reduce the occurrence of post-season bacterial nuclear disease. "
so you don't have to burn straw anymore!
"
old he looked excited. you make money from a rape? "
if you can't earn money, Lao He won't go home to grow rape!
,"
Wang Hanzhong said. years, The traditional cultivation mode of rape in China is unsustainable because of the high employment, the intensity of labor, the low efficiency and efficiency. Wu Kongming, vice president of the Chinese Academy of Agricultural Sciences, told reporters: China's main rape production area of the machine tillage rate is only
37%
, the machine broadcast rate is only
20%
, the yield is only
16%
, per acre of employment reached about
10
. Therefore, it is urgent to carry out the innovation of rape production technology model.
” In
2012, the Ministry of Agriculture incorporated rape into the grain production model plan, and together with rice and other food crops, unified deployment of the production mode. Immediately after, the Chinese Academy of Agricultural Sciences science and technology innovation project specially arranged
"
canola production production model research
"
topic. As the main undertaker of the task, Wang Han in the oil institute jointly with Huahua Agricultural University and other units, to carry out scientific and technological research. "
varieties suitable for machine harvest, is an important bottleneck restricting the mechanization of rape production.
,"
Wu Kongming said. The new varieties selected for oil breeding are the world's first double-low rape varieties with high oil content, strong anti-cracking angle, high anti-inverted, antibacterial nuclear disease as one, and are currently the most suitable rape varieties for mechanized production. At present, in Hubei, Hunan, Jiangxi,
5
production model demonstration base. in the ground, Ouyang Dunjun to Lao He calculated an account: the use of the whole mechanized efficient production model, rapeseed actual yield of up to
210
kg per mu, according to the purchase price of
5.5 kg
Yuan (new varieties of rapeseed oil content of
49%
, its purchase price can be higher than the general varieties
10%
or more) calculation, per acre of planting income
1155
yuan. Deduction of machinery, seeds, pesticides, fertilizers and other materialization costs per acre of about
425
yuan, labor input per acre
60,
yuan (clean ditch drainage), per acre of pure income of about
670
yuan.
"
canola is our public security county tradition, with reliable technology and machinery, I must also go home to plant rape!
"
Lao He told reporters. supply balance? Mengshan, secretary of the Party Group of the Chinese Academy of Agricultural Sciences, has worked in the agricultural sector for more than
30,
years, and like Wang Han, his concerns about the safety of china's edible oil are not a day away. "
oil has become China's international market dependence on the largest bulk agricultural products.
"
Chen Mengshan provided reporters with a set of data
- 1993-2013
, China's vegetable oil consumption increased from
763
million tons to
3081.4
million tons, an increase of
303.8%
, and annual per capita consumption rose from
6.4
kg to
22.8
kg, exceeding the world average of
20.
kg per year. In contrast, in the past
5
years, China's oil (including soybeans) seeding area basically hovered around
33
million mu, production in
47 million tons or
so fluctuations, the annual output of vegetable oil remained at about

10 million tons. The gap between the supply and demand of edible vegetable oil increased year by year, resulting in a sharp increase in China's oil and vegetable oil imports, the dependence on foreign countries rose rapidly,
2012, China
's edible oilseeds, edible vegetable oil net imports of
46.65
billion U.S. dollars, is the main cause of the international trade deficit in agricultural products. "
's edible vegetable oil self-seoppic rate is currently only about
40%
. In my opinion,
40%
is already the red line to maintain the basic needs of society, is to ensure the basic safety of China's vegetable oil supply bottom line!
” As for why
choose
"canola
"
to bear the burden? Chen Mengshan out of the original committee:
"
in recent years, China's many scientific and technological innovation around rape, has been able to support this burden.
” Chen Mengshan gave
5
examples in one breath: First, the world leader in rape hybridization research; Huahua Agricultural University Fu Tingdong academician has also been advocating to let rape to assume the heavy responsibility, his reason is: in the domestic oil crops, rape can use the southern winter idle field production, not with the main food crops, rape or rice, wheat and other food crops ideal rotation crops, after planting rape, can greatly increase soil organic matter, release phosphorus elements in the soil, fumigation to kill soil-transmitted pathogenic microorganisms, reduce the disease hazard of food crops. China's Yangtze River basin has about
1
50 million mu of idle winter farmland and beaches, if effective use, can increase the area of more than
60 million mu
of rape. hope that farmer Lao He
"
to go home to grow rape
"
be realized as soon as possible.
