When do American soybeans usually harvest?
The soybean harvest season in the United States begins in September.

In general, the soybean harvest time is from early September to 10 in early October. Soybean can be harvested when the stems and leaves begin to turn yellow and the seedlings and pods are dry and dark brown. It is generally best to harvest in the morning when there is dew, and put it down gently after cutting to avoid the loss of seeds as much as possible. Cut soybeans should be transported back to threshing in time to remove impurities, dried and put into storage.

The harvest time of soybean is very strict, and the harvest is too early, the seeds are not fully mature, and the 100-seed weight, protein and fat content are low. If the harvest is too late and the seeds lose too much water, a large number of pods will be blown up. Therefore, we must accurately grasp the harvest time of soybeans.

Different harvesting methods have different suitable harvesting periods, and the best period of direct harvesting is in the early stage of full maturity. At this stage, the leaves of soybean have all fallen off, the stems, pods and seeds all show the original variety color, and the water content of seeds has also dropped to about 20%-25%, so shaking the plants by hand will make a crisp sound.

If the sublevel harvesting method is adopted, it is necessary to advance the harvesting period appropriately, and it is generally considered that the yellow ripening period is the best harvesting period. During this period, 70%-80% of soybean leaves fall off, beans begin to turn yellow, a small number of pods become primary colors, and some still appear cyan, which is the best time for harvesting and drying.

Extended data:

In 20 17, China imported 95.53 million tons of soybeans, with an import value of 39.6 billion US dollars. Among them, 32.86 million tons of soybeans were imported from the United States, with an import value of $65.438+02.36 billion, accounting for 34.4% of the total imports.

However, after the Sino-US trade conflict between 2065438 and March 2008, especially after the decision to impose a 25% import tariff on American soybeans, the import cost of American soybeans rose sharply, and the number of imported American soybeans decreased significantly.

From June to August of 20 18, the United States exported 7.78 million tons of soybeans to China, a decrease of 3611390,000 tons compared with the same period of last year, with a reduction rate of 3 1.7%.

Affected by this, from April to August, 2065438+2008, the soybean futures price of Chicago Board of Trade (CBOT) fell by about 20%.

In recent years, the demand for soybeans in China has been increasing. In order to seize the soybean market in China, American farmers increased the soybean planting area. It is reported that the planting area of soybeans in the United States reached 36.24 million hectares this year, the second highest level in history, and it was the first time in 40 years that the planting area exceeded that of corn.

The first batch of soybeans planted on 20 18 has matured, which coincides with the soybean harvest season in the United States. However, China's demand for soybean imports from the United States continues to decline. At the same time, the world soybean supply may increase.

The USDA estimates that in 20 18-20 19, the soybean output in the United States will be1.173 million tons, and that in Brazil will be120.5 million tons. Due to good growth conditions, the soybean yield forecast data may be raised in the later stage.

At present, the soybean market exceeds demand, and the soybean price will continue to decline in the absence of other markets in the United States.
