Rice, the first thing we think of, is fertile soil and plenty of water, and it seems like only these places can grow rice.
But in the wisdom and efforts of the Chinese people, whether it is the desert or the plateau, whether it is fresh water or seawater, it can grow rice as well!
Here are three examples of Chinese people who have fought bravely and successfully planted rice in the land of China.
Sand farming: the new model of poverty alleviation
The sand can also grow rice and improve the ecological environment.
The summer of corqin sand, scorching sun, yellow sand dunes.
But over a great sand dune, the green water rice paddies strewn across the sandy land, let people shine.
The oasis in these deserts is the site of ecological restoration and utilization of the sandy soil in tongliao city of Inner Mongolia, covering an area of 500 mu.
Tongliao city is located in the well-kown horqin desert hinterland, nai, their jurisdiction, coulomb and other parts, basic no flat, fertile farmland, CaoMuChang also most degradation, desertification, salinization, farming and animal husbandry in sandy struggling, local farmers and herdsmen was once very poor, "sand more than, not rich in sand;
The sands are not rich.
Where is the way out of poverty?
The results of the survey have finally shown a glimmer of hope.
The underground water level in most areas of corqin sandy area is high and reserves large, and it is hot and hot, and the rain is hot in the same season and the frost period is long.
As long as the problem of water leakage in the sand is solved, reasonable and moderate development and utilization, the wide sandy resources are a great wealth.
How to overcome the problem of sand leakage in the sand?
In 1993, researchers in tongliao city academy YanZheZhu try using plastic as impervious layer, on the sand below 30 cm deep, with plastic liner made around the pool forget, next to the border check drilling Wells, build 1.8 mu of rice field, the autumn harvest the rice, the invention as a sand lining membrane comprehensive agricultural technology.
After a series of supplementary tests, the desert planting technique was popularized in the sand area of tongliao in 1995.
Nowadays, the sand lining membrane rice has been developed from the initial 1.8 mu experimental field to 50,000 mu, which has become the main thrust technology of the sustainable development of corkqin sand.
In 2015, the company entered the naiman flag in a scale development to build the largest desert organic rice growing base in the country.
Sea rice growing in saline-alkali lands
At the Qingdao sea rice research and development center in shandong province, the 234 varieties of rice varieties of different varieties of rice are now entering the flowering period in May, and the fastest growing will be harvested next month.
The sea is the visualization of the call of salt-tolerant rice, rice in the seaside beaches (is the land rather than the sea water) and so on saline-alkali land to grow rice, the growth of short-term unafraid to seawater immersion.
From experience, the rice is not salty, and grow rice taste in alkaline environment will be better, because the sea rice pests and don't get sick and don't need chemical pesticides, tidal flats in the state of natural growth, use less fertilizer, so is a natural organic food.
Why develop sea rice?
Mainly because our country has little arable land, but there are many saline-alkali fields.
At present, there are 1.5 billion mu of saline-alkali land in the interior of China, of which 200 million mu have the potential to grow rice.
If we can promote 200 million mu of mu, we will produce 200 to 300 kilograms per mu, and we can increase our food production by 50 billion kilograms and support about 200 million people.
This is also the dream of hybrid rice expert yuan longping.
(details: the 87-year-old is unusual: biao English, living in a mansion, rice in saline-alkali land...
-
At present, the sea rice is still in the development stage, after the sea rice is interbred for 8 generations, it can obtain the relatively stable strain, and finally the national variety approval procedure.
So in the short term, sea rice can't really serve the common people's table.
China has successfully planted rice on the plateau for nearly 20 years
Even if science and technology are so advanced today, it is hard to imagine that rice can be grown in low-temperature, low-temperature, high-altitude areas.
But what many people don't know is that in 1998, our country had mastered the technique of growing rice in the highlands.
The inland in qinghai province, the province's average altitude of 3000 meters, minus 5.9 ℃ to 8.7 ℃, annual average temperature is a typical plateau continental climate.
The fifties and sixties of the last century, is in different areas of qinghai province in rice, but due to the low level of production technology, have not been able to solve the problem of temperature difference between day and night and field permeable leakage, rice planting eventually failed.
In 1995, qinghai province academy of agricultural sciences' widely collected the cold rice germplasm resources both at home and abroad at the same time, actively for cold area planting technology introduction, selection, according to the characteristics of the plateau climate matching technology of assembly, through paddy cultivation technology research, solves the introduction of qinghai province rice more key soil seepage problem, improve the rice seed setting rate.
From 1996 to 1997, 24 cultivars were introduced in the early stage, with a solid rate of more than 80%.
1998, qinghai province academy of agricultural sciences' science and technology personnel according to qinghai HuangShui valley solar-thermal conditions good, saline-alkali land, the characteristics of the village in 13 varieties were tested, all mature, this suggests that as the only blank rice planting area in qinghai province has become a thing of the past.
According to the scientific and technological personnel, there are about 660,000 mu of land in the Yellow River and huangshui irrigated areas in qinghai province.
