From the "sea fishing" from 200,000 genes, he cultivated water -saving drought -resistant rice

"Research things, not just written in the paper

Also planted on the earth

Let everyone see, touch it ""

——Lori Jun, chief scientist of Shanghai Agricultural Biology Center

01

Cultivate the ideal of water -saving water and drought rice

Derived from a set of numbers related to the national conditions

In 1988, Luo Lijun saw a set of data in the library

"Agricultural water accounts for 70% of the total water consumption amount

And rice water for rice accounts for 70%of agricultural water ""

Traditional rice born with water

Not only will "drink" a lot of freshwater resources

And due to limited survivability

Large mountains, hills, Wangtiantian

They are all the areas they can't reach

my country's rice planting area is more than 400 million acres

70%of them are low -production fields

One of the reasons is

The large reduction of production caused by drought or even harvesting

Freshwater became a "tight hoop curse"

Break the rice output for the rice output difficulty

Lay rice dependence on freshwater resources

Can sow germination in the dry land

Since then, it has become the scientific research direction of Luoli Jun's focus on his life

02

To do a good job of agricultural research

Go to the field

"Take off your shoes, hit your barefoot, and go to the field to be farmers

Put on leather shoes and go to college podium, it is a professor ""

In 1988, when the Rollene team inspected the field in Guangxi

Surprise found the drought rice in the mountains all over the mountains

Although the amount of irrigation water for dry rice is less than rice

But the yield per mu is only more than 100 kg

And the rice is poor, not delicious

If the drought resistance of the drought rice

Combining high -yield high -yield and high -quality rice

You can make rice like wheat

Cultivation on the dry land to survive

Can also ensure yield and taste

Therefore, the Lorerian team joint breeding expert

Set on the road of hard and hopeful rice hybridization

03

200,000 copies of rice genes "the sea fishing needle"

Water -saving drought -resistant rice is widely covered

The Roles team began in 2000

Establish a "Shanghai Agricultural Gene Library"

93 subjects, 360 species have been saved

More than 230,000 variety resources

They go to the south and break the north for the rice variety inspection

Collect recovery of valid data for finishing, catalog, evaluation

Select high -quality materials and give them to breeding experts for breeding and hybridization

After more than twenty years of night, with the hard work of the day

The Lorerian team finally broke through genes and environmental bottlenecks

Cultivation of water -saving water -saving drought and drought rice is represented

Green Super Rice

And won the first prize of national science and technology progress

After comparative experiments, water -saving drought -resistant rice

Average water saving is about 50%

Little nitrogen fertilizer is more than 70%or more

Pesticide less ranked 80%or more

Greenhouse gas methane emissions decreased by more than 90%

Water -saving and drought -resistant rice can not only grow in the dry land environment

It also inspired the production potential of super rice

The average yield per mu was increased from more than 400 kg to 700-750 kg

Water -saving drought -resistant rice won the market with a high -quality taste

Under the promotion of local governments

The planting area in the country exceeds 4 million hectares

The total amount of planting seeds exceeds 10 million kilograms

Improved the level of food supply in more regions

Kuraki is solid and the world is full

The rice full of rice

A grain of crystal clear rice

Condense scientific researchers

For decades like a day's hard work

"Cherish food, cherish water

It takes a good ecological environment "
