The world's highest altitude rice yield record of 100 mu has been set again

The reporter learned from the Science and Technology Bureau of Lijiang City and Ninglang Yi Autonomous County in Yunnan Province on the 2nd that in Yongning Town, Ninglang County, at an altitude of 2,670 meters, on the fertile soil that has set the world's highest altitude rice yield record of 100 mu for many years, a record has been refreshed
again.
After the production test and acceptance of the expert group, the average yield of the 100 mu model of rice "Lijing No.
11" pre-control and post-control cultivation promotion technology reached 548.
93 kg, setting a new record
for 8 times in 5 consecutive years.

The production test was hosted by the Yunnan Crop Society, and relevant experts from Yunnan Province, Lijiang City and Ninglang County were invited to form an expert group to test and accept the 110 mu demonstration model of rice created by the major special plan of Yunnan Province "Breeding of New High-quality Japonica Rice Varieties and Integration of Green and
Simple Technology" on November 1.

In strict accordance with the "National Measures for the Acceptance of Production Measurement and Acceptance of the Creation of High Grain Yield", the expert group inspected 110 mu of model fields, randomly selected 3 of them, and used combine harvesters to carry out the whole field harvesting and moisture measurement
.

The results showed that the area of field 1 was 720.
05 square meters, the harvested rice was 475.
47 kg, the measured water content was 13.
76% after deducting 2.
77% impurities, and the actual mu yield was 431.
73 kg; the area of field 2 was 571.
09 square meters, the harvested rice was 491.
91 kg, and the measured water content was 13.
96% after deducting 0.
99% impurities.
The actual mu yield was 572.
14 kg, the area of Plot 3 was 691.
58 square meters, the harvested rice was 668.
53 kg, the measured water content was 13.
66%, and the actual mu yield was 642.
91 kg
.
After acceptance and calculation, the expert group concluded that the average yield of the model reached 548.
93 kg
per mu.

Yang Hong, senior agronomist of Lijiang Institute of Agricultural Sciences, introduced that Yongning Town is the highest altitude rice planting area in the
world.
This year's harvest record can be set again, mainly due to the promotion of high-altitude rice varieties and the improvement
of green production management technology.
The promotion of the new variety of "Lijing No.
11" will effectively promote the increase of production and income, industrial development and rural revitalization
of the masses in high-altitude and alpine rice cultivation areas.
