Ms. Jin, who lives in Downtown Jinhua, is a regular customer of Shenggui Family Farm in Jiangtang Town, Wucheng District. "The selenium-rich rice I bought is more than 3 times the price of ordinary rice, which is expensive but I think it is worth it." In addition to the high nutritional value of selenium-rich rice, Ms. Jin is more concerned about food safety.
Open the mobile phone APP, real-time visibility of the rice planting process: ploughing, sowing, pests, harvesting..." The rice planted under your own eyes is more at ease. Ms. Kim said.
Customers eat rice and look at their mobile phones, and growers also look at mobile phones when they grow grain. The screen is a little bit, the agricultural machinery service is placed with one click, the rotary cultivator, the drone, the machine operator, etc. are in place in time, and the "look at the sky and the land" has become "look at the screen to plant the land" and "look at the data to plant the land". At present, it is the spring ploughing season, and the reporter walked into shengguiyou family farm, one of the earliest family farms in our province that used digital grain cultivation, to experience the digital growth journey of a grain of rice.
Agricultural machinery services One-click order
In the town of Jiangtang in early April, the rain is pouring down, and the smell of the cultivated earth mixed with a little grass adds a special freshness to this spring day. The first early rice seeds were sown in neat rows, and the green, short, patchy paddies stretched out into the distance. As the person in charge of this rice field, 52-year-old Sheng Guiyou stood on the field and smiled.
"The weather forecast says it will rain tomorrow, do you still go down to the field as usual?"
"It doesn't matter, you come."
The day before the interview, we made a point of making a phone call with him. Sheng Guiyou said that unlike the previous hand tractor ploughing, the cab of the rotary tiller is in good condition, and it can work as usual regardless of whether it is sunny or rainy.
Looking at the field, two rotary tillers kept "advancing" back and forth, and it only took a few minutes for a paddy field to be ploughed. "Rotary cultivators and other agricultural machinery, we all make reservations through mobile phones." Saying, Sheng Guiyou opened his mobile phone to show us. According to the situation of Sheng Gui, the agricultural machinery service center divides the ploughing business into professional service agencies and machine operators, who will go to the field to serve according to the agreed time. In addition to ploughing, planting, harvesting and other work, this farm is completed through the agricultural machinery service company orders. "Today we are going to plough 50 acres." Sheng Gui had an introduction.
"After the rice field is ploughed, I immediately apply the base fertilizer." Wang Huizhong, 53, is a worker at Shenggui Family Farm, where he has been working for 14 years. In order to make the soil fertile longer, the base fertilizer is applied on the farm before sowing.
"In the past, artificial fertilization, a person could only work five or six acres a day. And now, I spray thirty or forty acres a day. "The adjusted base fertilizer is sprinkled around by the machine, and the water splashes in the paddy field. Wang Huizhong walked around the field with the fertilizer spreader on his back, and the base fertilizer of a rice field was applied.
The next few days of trenching and sowing were all machines. "By April 7, our farm has completed the sowing of 770 acres of rice paddies." Sheng Gui said.
As a customer, Ms. Jin can understand the whole process of production through the mobile APP. As the head of the farm, Sheng Guiyou also has more time to control the production situation throughout the mobile phone or the electronic screen in the office. "With a digital field management system, you don't have to run into the field all day long to understand the specific conditions of the field."
Rice field irrigation is calculated precisely
It is said that the weather in spring is a child's face, which changes three times a day. On the day of the interview, thunderstorms came and went. "I don't know when it's going to rain." When sheltering from the rain, we muttered to ourselves.
Sheng Guiyou immediately took out his mobile phone to check it, and then told us very confidently: "This rain, it will not rain soon." "It turned out that in the fields of his farm, weather monitors were installed. Compared with the general weather forecast, the temperature, humidity and wind force in this area can be predicted more accurately.
Sure enough, the shower ended quickly. In addition to the weather, how much water to "drink" in each rice field is also accurately calculated.
"Two days before ploughing, I turned on the irrigation system in the field, which is also the most expensive time of the year." On the edge of a water channel, Sheng Gui pointed to the camera above and told me that through it, I could accurately calculate the flow of water in the canal. When irrigation water meets the needs of use, the system automatically alerts you. "Tell us with the data that Tian has drunk enough." Sheng Guiyou quipped, "This guy is very smart." ”
Through the professional calculation of the Jinhua water conservancy department, using this digital water-saving system, Shengguiyou family farm can save one-third of irrigation water a year.
In order to realize the digital management of the field, high-tech products in the field are indispensable. In this family farm, there are hidden university questions everywhere.
During the interview, small white plastic boxes on the edge of each field attracted our attention. Horizontal and vertical rows, evenly spaced, from a distance, like a uniformly dressed "field guard".
"This is a trap." Sheng Gui has introduced that when rice begins to grow, these "field guards" can play a role. The dimorph borer is a natural enemy of rice. Traps trap male moths by emitting pheromones from female dimorphs, so that females cannot mate normally and lay eggs to inhibit population growth.
In order to catch insects more efficiently, large intelligent insect forecasting lights have also been installed in the fields here, which can monitor diseases and pests in 500 to 1,000 acres of rice fields. "Turn on the lights at night and use the dimorphism to attract them. Probes inside the forecast lamp capture and monitor the number of dimorphs flying in each night. "This machine is networked by three parties between the provincial and municipal plant protection stations and the farm." Once the number of two borers exceeds the warning line, the experts at the plant protection station will call to remind them. ”
In Jinhua, Jiang Tang's selenium-rich rice is famous. The amount of selenium-rich content is not something that growers brag about casually. In the case of these rice fields in Shenggui's family farm, there are accurate data on how many trace elements are in each field.
In the rice fields, there is a piece of "idle" land, which does not plant seedlings but buries pipes. Last year, the long-term positioning monitoring point for cultivated land quality in Zhejiang Province, funded by the Provincial Department of Agriculture and Rural Affairs and the Provincial Department of Finance, and implemented by the Wucheng District Agriculture and Rural Bureau, was completed and put into use. The soil fertility in the area is monitored through data analysis within the pipeline. "It can measure the content of nitrogen, phosphorus, potassium and other elements, allowing us to apply fertilizer more accurately."
Online and offline to build a brand
Drones, planters, fertilizer spreaders... In the warehouse of Shenggui family farm, all kinds of modern machines are readily available. "In order to better mechanized operation, my nephew specifically studied drone flight and passed the relevant exams." Sheng Guiyou proudly said that with these machines, the 770 acres of rice fields only need 3 people to take care of them all year round.
Taking the half month of spring ploughing as an example, he calculated an account for us: "In the past, the salary of a small worker was 150 yuan / day, and our farm needed about 20 people, and the labor cost was 45,000 yuan. Now the machine is replaced, the cost of the worker is 500 yuan / day, but the number of people is reduced to 3 people, the fuel cost of the machine is 200 / day, and the total cost is 28,500 yuan. From the perspective of the whole year, the labor cost alone can save more than 100,000 yuan. ”
A grain of rice is very pure, which is full of the efforts of the grower, and the grains are sweet. A grain of rice is very complicated, from the ploughing of the land to the harvest of rice, it takes many months, and the grains are hard.
In the Jiang Xianyong family farm in Jiangtang Town, a rice transplanter of 20,000 yuan began to plant seedlings in the field on the 12th. "In the past, one person could only plant 1 acre of land a day, but now a rice transplanter can be planted with 2 people, and 30 or 40 acres can be planted a day." Jiang Xianyong said that at present, he has contracted more than 900 mu of rice fields in Jiangtang Town, which is estimated to be expanded to more than 1,000 mu in the second half of the year. "With such a large planting area, digital and mechanized planting is even more indispensable."
"The application of digitalization is not only changing the way we grow, but also the quality of our products." Sheng Guiyou said that his family's ecological rice is now priced at 6.8 yuan to 20 yuan per kilogram, which is about 3 times that of ordinary rice, but it does not worry about sales.
It is understood that in 2013, the rice sales of Shenggui family farms were about 10 tons. In recent years, through online and offline walking on two legs, sales have increased to more than 300 tons. "Our rice sells by word of mouth."
The application and sales model of digitalization have made Sheng Guiyou taste sweet, and also brought future development direction to other growers in Jiangtang Town. It is reported that at present, 19 large planters in Jiangtang Town have set up a joint society, and the area of grain planting is as much as 6,700 mu. Everyone is developing in groups, and more and more growers are beginning to move towards the digital road of growing grain, and constantly launch the brand of Jiang Tang's selenium-rich rice.
