Checking the moisture content of his wheat, Li Wenzhou knew the time had come to start harvesting his crops last week.

Using a pair of combine harvesters, Li can harvest his 40 hectares of winter wheat in Qixian county, Henan province, in less than two days.

“Reapers can do everything from cutting and threshing to collecting grain, which helps us reduce grain loss,” Li said. “We don’t need to do a series of laborious operations such as moving crops and threshing plants for grain by threshing the cut stems, which can also lead to losses.”

Li said the average wheat production per hectare this year is expected to be 9.75 metric tons.

The summer winter wheat harvest is the first of China’s annual grain production effort.

Harvesters have been widely used across the country to minimize grain losses.

China has more than 650,000 wheat combine harvesters that can be used this year, which basically meets the demand for necessary machinery, the Ministry of Agriculture and Rural Affairs said recently.

Nearly 80% of winter wheat has been harvested nationwide, according to official data released on Sunday.

In Henan, a major wheat-producing area in China, 5.66 million hectares of wheat had been harvested as of Wednesday, accounting for 99.5 percent of the total cropping area in the province, data showed. Henan Provincial Department of Agriculture and Rural Affairs. .

The province had 62,000 combines working in the fields on Wednesday.

In Shandong Province, another wheat-growing area neighboring Henan, 2.34 million hectares of wheat were harvested as of Sunday, accounting for 58.4 percent of the province’s total area, according to data from the Provincial Department. Shandong Agriculture and Rural Affairs. Over 99 percent of the area that has ever been harvested has been harvested with machines.

“I am using locally made harvesters this year, and they cut the crops cleanly. The grain loss rate has been reduced to less than 2 percent,” said Han Guode, who heads an agricultural cooperative in Zoucheng, a city in Jining, Shandong. “We can get 25 tons more grain from the 306 hectares of wheat fields in the region compared to previous years.”

Drivers are trained for days before starting to harvest.

“If the crops are relatively dry, the wheels should not turn too fast, otherwise some of the cut crops will fall into the field instead of being conveyed to the processing part of the harvester,” said Qiu Teng, a driver in Zoucheng. .

Agricultural authorities cooperated with health, transport and meteorological authorities to ensure a smooth harvest.

Emergency harvest teams have been set up to harvest crops from farmers who cannot do the work due to epidemic controls.

In Henan, 1,460 gas stations have special filling channels for combine harvesters offering a 3% discount.
