Rice grows 6 crops a year!

A few days ago, good news came from the Chinese Academy of Agricultural Sciences: The rice cultivation project jointly developed by the plant factory innovation team of the Institute of Urban Agriculture of the Academy and the Qian Qian team of the China National Rice Research Institute has made significant progress.

"Raised" crops

As we all know, sunlight, soil, and moisture are indispensable factors for crop growth

In addition to light, water and nutrient supply, there are many factors that affect the growth of rice, such as temperature, humidity, and carbon dioxide concentration

"Another advantage of the plant factory is that it is relatively isolated from the outside world, the air is purified, and people need to wear protective clothing when entering and exiting, which can effectively block pests and viruses

Realize rapid breeding

Yang Qichang, director of the Urban Agriculture Research Institute and chief scientist of the plant factory innovation team, told reporters that the greatest significance of achieving the important breakthrough of harvesting rice around 60 days after planting is to speed up the breeding speed and provide a new solution to ensure national food security

For most crops, it takes several generations of breeding and breeding in order to cultivate new and excellent germplasm

"Traditional breeding methods can only produce one to two generations a year.

In the plant factory, the environment and nutrient elements of plant growth are precisely regulated to greatly increase the photosynthesis rate of crops, induce early flowering and promote the rapid growth of crops, greatly shorten the growth cycle of crops, and achieve rapid breeding

Yang Qichang said that in the future, the number of cultivation layers in plant factories can reach more than 10, and the breeding work will be more efficient and convenient, which has important practical significance for ensuring food security

The development direction of urban agriculture

In recent years, many plant factory projects have also appeared in China

One day in the future, will we be able to see other agricultural products produced by plant factories on the market?

Bian Zhonghua believes that this is entirely possible

However, with the development of related industries and breakthroughs in key technologies, the cost and operating cost of plant factories will also be reduced

"The value of rice is relatively low, and large-scale promotion is difficult, but this model provides a new way and way to solve food safety problems in the
