40 ° C at high temperature "Draw 900 Circles" Tianfu Granary "Harvest Verification Officer" is rice testing

Cover reporter Li Qing Wang Yuexin

On August 16th, at the entrance of Jinguang Village Committee, Dongpo District, Dongpo District, Meishan City, Sichuan Province, Wang Ze, Chief of the Agricultural and Rural Survey Section of the National Bureau of Statistics, carried a small bag of rice samples to announce: " As a result, this year Jinguang Village ’s“ Fang Fang ”is 654.65 kg of rice fields, and it is a bumper harvest!"

Sichuan, which has always been the top ten grain output across the country, is currently ushered in the harvest season of rice. On August 16th, cover reporters came to Dongpo District, Meishan City, Meishan City, Sichuan to see how the "harvest verification officer" was measured for rice to measure the safety of food. "".

"Real cutting and actual measurement" on the scene holding the "round rules" in the ground painting circle

"This paddy field is good at first sight. The rice grows tall and the ears of the rice!" In the early morning of August 16th, the investigators of the Meishan Investigation Team of the National Bureau of Statistics came to the rice fields in Jinguang Village, Taihe Town, Dongpo District. side. They are here to calculate the rice output of the rice acres in the sample land.

Jinguang Village is located in the core area of ​​Meishan's Minjiang Modern Agricultural Park. It has an area of ​​more than 7,900 acres of cultivated land in the village and more than 4,600 acres of high standard farmland. It is a veritable grain -producing village.

What is the output of the village this year? In order to know more accurately, the investigators brought straw hats and took measurement tools to shuttle in the rice fields, and began to measure production.

At the high temperature of 40 ° C, Wang Ze guided the staff on the spot, took the diagonal to select the sample with the diagonal, and then took the measurement of the measurement, the sickle down the wheat land, first cut the heart, tightly fixed the measurement round rules, and then painted while drawing while drawing. Harvest in the circle and while. In the end, round samples were cut in the rice fields. "A sample is 10 square feet, about 1.1 square meters. 3 samples per land."

Subsequently, the investigators brought the harvested rice samples back to the village committee. After the procedures such as despairing, drying, and removing impurities, weighing the water content of the sample with the water measurement instrument to obtain the sample hair weight. Finally, after the formula, the standard per mu of rice was 654.65 kg.

"Compared with last year, the number of fields in this field increased by 1%-2%, and this output can be ranked at the forefront in the province." Wang Ze said that starting from the end of July this year, Meishan organized a grain production team to go deep into the fields into the fields. On the ground, the actual measurement of the food cutting food in the city's 100 production points in the city. ","

900 points in 100 villages depend on both satellites and old farmers

So, how is the production point of each place determined?

"This is not random." Wang Ze introduced that in the annual measurement of rice, the National Bureau of Statistics will first determine 3 yuan*200 meters (about 60 acres) for each village through satellite remote sensing. piece. Then the estimated group composed of investigators, senior farmers and professional cadres will estimate these plots, and select three measured plots with high yields, middle -class, and low yields. After that, the production is measured by sampling and weight.

In the middle, there are a lot of fine work to do. It is necessary to overcome the "not beauty of the sky" and strictly control each link in order to ensure that the measured data is accurate.

Li Yan, a staff member of the Urban and Rural Economic Monitoring Center in Dongpo District, Meishan City, said that after satellite determines the sample plots of 100 villages in Meishan, they will choose the most experienced old farmers with local village cadres to give these sample plots "Ranking".

"For example, the 60 -acre land of Jinguang Village is divided into more than 60 yuan. After watching the old farmers, it will divide it into three parts: high -yield, middle -class, and low yield. It is similar to more than 60 students in a class. The medium and poor grades. "Li Yan said, then randomly draw one as a representative from the three sequences.

"After confirming the three plots of each village, three samples will be selected in each land." Xu Qiang, deputy head of the Agricultural and Rural Survey Section of the Meishan Investigation Team of the National Bureau of Statistics, said, "For example, the land we measured now, The first diagonal measurement was measured, and the length was 46 meters. Except for 4 after 4, a sample was taken every 11.5 meters along the diagonal line, and there were three samples to comprehensively calculate the output of this land. "" This way. " The measurement method is very scientific, and the calculated data is almost no error in the output that has been harvested. "Wang Ze said that counting accurate food production can not only know the productivity of food, but also fully grasp the growth of grain and affected situations. Based on the scientific basis for the sales price and structural adjustment of the year and the next year.

Grain "counting in the heart" helps to create a new era "Tianfu Grain"

As a part of the "Tianfu Grassay", in the past ten years, Meishan City has stabilized the area of ​​grain sowing and grain output, and the production has always been at the forefront of the province. Among them, Dongpo District and Renshou County are national grain -producing counties. Renshou County's grain production ranks among the top five in the province. It has been rated as a national advanced county in grain production for 13 consecutive years.

For such an agricultural city, grasping the "food bags" in your hands, accurately grasping grain production, is of great significance for ensuring the safety of food safety and creating a "Tianfu Grain" in the new era.

Such a small bag of food can measure the perurone of a field. If you want to calculate the output of the city, you need 300 such measured fields. According to Wang Ze, this year's Meishan's grain production work, a total of 100 administrative villages in the city have been used as the production point. Among them, 20 points are selected as Dongpo District and Renshou County, which are produced in the big county, and 15 points are selected for other non -grain counties.

Investigation team members are measured rice

It is understood that Meishan's grain measurement work was first carried out in the 2016 wheat measurement, and it also adopted the measurement method of "actual cutting and measured". While investigating the production teams, they also trained a number of young auxiliary measurement players who understand agricultural knowledge and operate operations at various measurement points. Every year, the investigators will walk in the vast fields with the majority of the auxiliary surveyes to measure the production of the food production of Meishan City.

This year, the survey of Meishan Autumn Grain's survey is corn and rice. At present, corn measurement has ended, and rice production has been completed by 60%. "It is expected to complete all the work of rice production in early September, and then report to the National Bureau of Statistics, and finally obtain accurate production and total output." Wang Ze said that from the current data, although this year The level of modern agriculture is high, "Please rest assured, the rice bowl is stable!"
