Observatories: guangdong is one of the main rice-producing regions of the south of the country, growing around 28 million acres a year, almost 30 per cent of which are low-yielding fields, with the acre production hovering for a long time at around 300 kg. New changes are taking place here with the application of new technologies for the landing of saline-resistant varieties, carbon nitrogen balancing。
This is the gate to the guangdong sea, which was previously a saline land and is now a rice field. It's very thick, and look at it very carefully. It was just a sap, and now it's got more than 20 effective saps, more than 20 solid straws。
The rice varieties grown here are known to be “19 fragrances” and to be saline-resistant, high-yielding, high-quality and, for almost two years, highly popular in the door zone. The varieties are selected by the local agricultural and rural directorate from more than a dozen new varieties through multiple re-testing and rigorous comparison, and eventually emerge as the preferred species。
In interviews, journalists found that in guangdong, in addition to salin beaches, there were also low- and middle-yielding fields such as sands fields, sticky fields and thin slag. The common problem with these “mindfields” is not lack of fertilizer but “indigestion”. In the new zone of the pearl sea, a new technology that seeks to break the “crawling” dilemma of crops is opening the door to increased production in these “spreadfields”。
Attention is drawn to the fact that, at the foot of the journalist, the soybeans are growing on the side of the field, which, in fact, shows a lot of water. In addition, many areas adjacent to the land are fertilized, indicating that the soil contains very high water content and that it is quite difficult to grow with soybeans。
Liu, the technical director of the china farmers group (cangdong) biotech industrial park, called it: “whether it is the fruit of sandstone fields or the nutritional technology of carbon nitrogen balance”
The reporter asked, "is this a new technology?"
Liu xing replied: “yes, it is innovative technology, and it is a new quality of productivity, agricultural quality of productivity.”
For arable land, crops can grow healthy only when the carbon and nitrogen ratio is appropriate. Thus, the “carbon-negative balance” technology addresses the bottlenecks of low nitrogen fertilizer utilization by adjusting carbon and nitrogen ratios and achieves “fat-free production”。
Xu bae-ji, a researcher at the institute of agricultural resources and environment of the guangdong academy of agricultural sciences, told journalists that it was strange to see the crops in the ground growing so badly. For example, it's like people eat too much to produce "accumulation," and "carbon nitrogen balance" nutrition techniques capture the "crushing" control that makes nitrogen a real "muscle" for crops rather than "fat" in the soil。
Journalists saw that the problem of “food accumulation” had been resolved and that more low- and middle-income fields had recovered their “eating appetite” as new positions for increased food production。
According to wang xinlong, a member and deputy director of china's agricultural production information group, “this year we have developed a special technical food package, with the application of bottom and leaf fertilizers, the effects of which have been mainly reflected in the promotion of soil improvement and the development of its roots”
According to statistics, this year, through the widespread application of smart agricultural machines, precision fertilization and bio-improvement techniques, the town of doomen-lync produced 553. 3 kg of model acres, a new record of local monolithic rice production。
The "improving password" for low- and middle-yielding fields: the "relay race" for microorganisms. Workshop
The crop's “crop” has been cured, but where did it come from? Journalists visited the “carbon-nith balance” workshop in situ。
When i walked into the factory, the reporters first smelled a sweet silk, a perfume, where was the mystery? Let's find out. Isn't it a bit like chocolate marmalade, the smell of fragrance and sweet silk coming from here? It's actually a carbon nitrogen nutrient, which is given to daejeon crops。
It sounds amazing, but the raw materials are very gaseous: red sugar, soybeans, spirulina, all food-grade organic materials. But to turn them into high-tech carbon-based fertilizers, they rely on a “relay race” of micro-organisms — a step-by-step dismantling of crops from hard-to-absorbed “big molecules” to highly absorbed “small molecules”。
It is not enough in the workshop and in the laboratory to “smelt” and to be accounted for by the crops and have to go to the fields. New discoveries were made by journalists at the great sand farm in dominique。
"there's a white root coming out."
The reporter said, "this is a very small one, and you're called the white root?"
Ho yoon said, “the root comes out, absorbs nutrients and feeds it up to the rice, and the rice is full.”
The white root is the most direct sign of rice “to eat or not to eat”. And behind this "white root" is the carbon-nitrogen balance technology that works. From the initial laboratory validation to the multi-dot field validation carried out in different ecoregions of the country, the team has travelled for almost 10 years. In daejeon alone, the team placed hundreds of test sites in different rice areas, ranging from south-west china, south-west china and mid-downstream of the yangtze river, covering a variety of adverse soil types from salin beaches to sandstones. Today, carbon-nitrous-balancing technologies have been validated in over 50 crops in 10 provinces of the country, covering over 2 million acres, helping to transform more low- and medium-yielding fields into “high-yielding”。
