On the day before yesterday (26 days), the first test of fast-growing rice seeding by the scientific team of the chinese academy of agricultural sciences was successful in xinjiang and tian desert greenhouses。
Three layers of cultivation in the greenhouse shed were planted in just two months
Early in the morning, in the greenhouses of xinjiang and manacre desert facility agricultural industrial park, researchers and local agricultural technicians of the institute of urban agriculture of the chinese academy of agricultural sciences were busy harvesting rice. The rice, which is grown on three-storey plantations, covers only one acre of the greenhouse shed, from planting to harvesting for two months。
Wang sam, researcher at the institute of urban agriculture of the chinese academy of agricultural sciences: this time we used the local new rice type 1 rice, using a technical method of rapid breeding, which took us 15 days to plant the rice seedling into this non-earthly-cultivated trough。
How can desert greenhouse rice shorten nearly half its growth cycle
My country is the world's oldest rice grower, growing rice for an average of 120 to 150 days from the north to the south, and why can fast-growing rice grow in xinjiang and the desert greenhouses shorten the growth cycle by almost half
Plant plant model controls environments such as temperature humidity light
In 2021, the research team led by yang, the chief scientist of the institute of urban agriculture of the chinese academy of agricultural sciences, after five years of research, at the chengdu plant in sichuan, halved the length of rice production by means of rapid breeding techniques, and achieved technological breakthroughs throughout the year, with no seasonal continuity。
The chief scientist of the institute of urban agriculture of the chinese academy of agricultural sciences, yang zhi, said that under the conditions of a plant factory, we could control its temperature, humidity, light, carbon dioxide and inter-root nutrients, that is, the environment. However, in the context of plant plants, energy costs, operating costs and construction costs are relatively high. So we want to take advantage of the desert's greenhouse conditions, because the desert's greenhouse is a place where light and heat resources are good。
Plant factories built in the desert to halve the length of rice births
In wanda, many greenhouses are built in flat deserts, which are much cheaper to build than land for inland use, and the special geographical conditions for wanda are long daylight hours and high temperature differentials between day and night, which contribute to better crop quality. Scientific teams have replaced soil with precision trophic fluids in the fields for soil-free cultivation, followed by light and temperature control interventions for rice through artificial light sources and environmental regulation techniques. After more than two years of testing, the team finally managed the critical challenge of growing rice under desert greenhouse conditions。
Using light-hot resources to explore rapid crop breeding techniques
Following the halving of the reproductive period of rice, yang's scientific team is currently exploring key technologies for the rapid growth of staple crops such as soybeans, maize and wheat, as well as oilseeds, cotton and aluminum, in the desert greenhouses of kaza。
With sufficient light and heat resources, this breakthrough in fast breeding technology for desert greenhouse crops provides technical support for the future use of desert greenhouses in south china for crop anniversary and rapid breeding。
What techniques support desert greenhouses for fast-growing rice
In xinjiang and the desert greenhouses, where rice has grown rapidly and quickly, what techniques are behind this new technological breakthrough to support shorter reproductive periods
A circular machine for 50 acres of rice
In the greenhouses of xinjiang and the desert, journalists saw that the rows were ripe rice being harvested, another row was rice that had already begun to pump, and another batch of rice was growing on a circular machine。
Yang jun, assistant researcher at the institute of urban agriculture of the chinese academy of agricultural sciences (the grim machine) allows light to be fully irradiated on every plant, allowing it to grow evenly, a machine that can provide 50 acres of seedlings for rice demand, and can produce an anniversary breeding plant. The seedling, which is now born on 10 april, has been in existence for 10 days and will be ready for planting in five days。
Vertical 3d soilless. Artificial light-based intelligence
The rapid growth of rice in the wanda greenhouses, using vertical stereo-free cultivation technology, provides crops with good conditions of production such as light, temperature, water, gas, fat, etc., in the light of artificial light sourced intelligence led。
Research associate, institute of urban agriculture, chinese academy of agricultural sciences, stadium: through one of our led lights, a light formula can be constantly regulated, combining precision lighting with a measure that can quickly shorten the breeding cycle of rice itself。
There is a vast desert and a good light-hot resource in the wanda area, which is an ideal site for research using non-cultivated land in facilities agriculture。
Desert greenhouses, energy efficiency and competitiveness
Reducing the costs of plant plants, desert greenhouses will be an urgent issue for future agricultural development of researchers and facilities。
The chief scientist of the institute of urban agriculture of the chinese academy of agricultural sciences, yang zhi: this energy-efficient desert complex, which we are exploring in wada, cost only about $350 a square metre, is a third of the glass greenhouse in the netherlands. At the same time, we can spend about 25% of the dutch glass greenhouse, which in the future can be combined with new energy sources, as well as with mechanized, equipped, and intelligent technologies, and whose construction and operation costs will be significantly reduced, and which will be highly competitive internationally。
