We all know about machine transplanting, but at the same time as planting seedlings, you can also fertilize, have you ever seen it?
In the core area of the provincial grain production functional zone in Yanjiang New Village, Zhuji Jinan Subdistrict, several machines in the rice field are shuttling back and forth, which at first glance are no different from ordinary rice transplanters, but in fact they can complete two operations simultaneously: planting seedlings and fertilizing.
Originally, this seedling planting technique was called "side deep fertilization".
Compared with the general rice transplanter, it has an additional fertilizer machine and fertilizer bucket, which can automatically turn over the soil on the edge of each seedling, bury the fertilizer, and then cover the soil at the same time.
According to the previous agricultural operation practices, whether it is planting early rice or late rice, after the paddy field is ploughed and leveled, the base fertilizer should be applied first, and then the seedlings should be planted. Conventional fertilization is manually sprinkled inefficiently, the amount of fertilizer is all based on the feel, and there is also the problem of uneven sprinkling. In addition, manual throwing, after stepping on the foot will leave a hole in the paddy field, which is easy to cause the situation of "grass growing in the high place and drowning the seedlings in the sunken place".
Lateral deep fertilization achieves "targeted precision fertilization", which can better solve these problems. In particular, slow-release fertilizer can slowly release nutrients to meet the nutritional needs of rice at different growth stages, which is better and more economical than conventional fertilization.
Xuan Ping, head of Yanyu Family Farm in Yanjiang New Village, is very happy to say that her family farm has expanded the application area of the new model of fertilization this year.
The average yield of the two crops of rice planted last year was about 1,200 kilograms per mu, and the yield increase effect was very obvious. At the same time, the amount of fertilizer used and the input of labor costs have decreased significantly compared with previous years.
In June, the technology also attracted more than 100 people from the China Rice Research Institute, the Provincial Department of Science and Technology, the Provincial Agricultural Technology Extension Center, the Provincial Institute of Environmental Soil of the Academy of Agricultural Sciences, and the agricultural technology departments throughout the province to observe the scene.
At the same time, in 2018, the rice field at the mouth of Xinnancun Village was reduced by nearly 20% compared with the conventional fertilization and chemical fertilizer application of farmers, the amount of chemical pesticides was reduced by more than 48%, and the theoretical yield increased by 4%. And what is this all about?
Originally, this rice field was a core demonstration area of the national key research and development plan project "Integrated Research and Demonstration of Rice Fertilizer and Pesticide Reduction and Efficiency Enhancement Technology in the Middle and Lower Reaches of the Yangtze River" hosted by the Provincial Academy of Agricultural Sciences.
This rice field in Xinnan is very interesting, and farmers have planted some honey source plants that red-eyed bees and tasseled wasps love to eat in the rice fields of the demonstration area, so that they can eat and live, and reproduce. The red-eyed bee and the wispy wasp are the natural enemies of the main pests of rice borers and rice planthoppers in our province, so that they can help farmers eliminate pests and use ecological control technology to improve the "immune system" of rice fields, so as to achieve the purpose of "weight loss".
In addition, at the moment of the development of science and technology, agriculture has become inseparable from science and technology. In the farmland of Jinan Street, if you see someone operating a drone, there is a good chance that the farmer's uncle is fertilizing the field! The application of these advanced agricultural machinery makes pesticide application more precise and efficient.
Farmers can also download the "Nutrient Expert System" on their mobile phones. The system can calculate how much fertilizer and what type of fertilizer should be applied to each piece of land, helping farmers reduce unnecessary nutrient inputs, organic nutrient substitution and other technologies have improved fertilizer utilization, and rice fields can burn a lot of "calories".
