Rice seedling raising is an important part of rice yield and harvest. Pengshan District, Meishan City, Sichuan Province is located in the core area of "Tianfu Granary", at present, it is the time for rice seedling raising here, where rice seedling raising not only realizes streamlined production, but also takes the elevator.
Reporter Yang Ni: My current location is the digital and intelligent rice demonstration base in Pengshan District, Meishan City, and the local rice seedling raising work has begun in the past few days. Now the villagers are busy carrying the seedlings from the seedling tray conveyor belt, stacking them neatly and moving them to the field, after which they will also carry out the work of applying pesticides and mulching. Today's batch of seedlings can be transplanted after about 30 days, and the seedlings of one acre of seedling field can ensure the seedling demand of 120 acres of field.
Reporter Yang Ni: This year, we found that more intelligent equipment has been invested in the local area to improve the efficiency of work. For example, in the seedling factory at this base, this year for the first time to use this set of automated sowing line, from the tray, soil covering, watering, to sowing, pesticide application and then covering the soil, a seedling tray is completed, the whole process to achieve digital control, we see that only three people can be completely operated. This set of assembly lines can sow about 2,400 trays of seedlings per hour, more than 20,000 trays a day, which can meet the needs of seedlings of 1,000 acres of fields.
Reporter Yang Ni: The traditional open-field seedling raising is generally a cycle of 30 days. A seedling raising season is generally carried out two rounds, but it will face the uncertainty of weather conditions, and this circulating intelligent seedling raising machine by my side can solve this problem.
Reporter Yang Ni: A set of circulating intelligent seedling raising machines is 5 meters high, and these seedling trays are constantly rotating as if they were on an elevator. We also saw that there was a sprinkler system that could replenish water and nutrients in a timely manner. Now the seedlings are growing very well, they are evenly distributed, each plant is about five or six centimeters tall, and the seedlings can be transplanted after a maximum of 10 days.
Reporter Yang Ni: Through this kind of high and low staggered way, one is to increase the number of units and reduce land and labor. In this factory, there are a total of 2 large and 2 small total of four such circulating seedling machines, a total of 7,600 rice trays can be placed, but the area is less than 400 square meters, and the seedlings planted in a round can be close to 400 acres. At the same time, the seedling greenhouse also brings convenience to the growth management of seedlings, provides a stable environment for temperature and humidity control, can effectively prevent the risk of climate instability, such as cold spring or high temperature weather, further improve the quality of seedlings, and ensure the survival rate after transplanting the field. The seedling raising cycle of the circulating seedling raising machine is about 18-20 days, which is about 5-10 days less than the traditional open field seedling raising, and can realize three rounds of seedling raising in a seedling raising season to meet the needs of some farmers for early planting and late planting.
Reporter Yang Ni: In fact, in addition to the link of raising seedlings, the entire demonstration base has realized digital management in many aspects, such as intelligent irrigation systems, monitoring equipment for pests and diseases, etc. Through the application of information technology, agricultural monitoring and remote operation can be realized on computers and mobile phones. These digital and intelligent means have greatly improved the efficiency of agricultural management and made agricultural production more scientific and technological.
