How many kilograms of soybeans are generally produced per mu in Northeast China? What is the highest yield per mu?

Northeast soybean yield per mu

Generally, under good planting conditions, the soybean yield per mu is about 400-500 jin. The soybean yield in Northeast China is higher, probably around 800 to 1,000 jin per mu. The yield in Heilongjiang region is around 500-700 jin per mu.

Northeast soybean planting prospects

The cost of soybean cultivation in Northeast China is about 400 yuan. The current market price of domestic soybeans is 3.7 yuan per kilogram. Based on a yield of 160 kilograms per mu, the gross income per mu is less than 600 yuan. In recent years, with the improvement of planting technology, farmers' income per mu is close to 800 yuan.

Domestic soybeans produce little oil, while imported soybeans from the United States and Brazil are mainly high-oil genetically modified varieties, which are mainly used for oil extraction. They have a high oil yield and are relatively cheap, about 10-40 yuan cheaper than traditional soybean oil. They quickly occupied the Chinese market, so the prospects for soybean cultivation in China are not optimistic.

How to grow soybeans in Northeast China to achieve high yields

1. Seeding and planting

Northeast soybeans can be sown and planted. First, select seeds with full grains and no diseases or pests. Then soak them in clean water, remove the seeds floating on the water surface, and then pick out the seeds that sink to the bottom of the water. After drying, sow them in loose, breathable, nutrient-rich humus soil.

2. Provide nutrients

Northeast soybeans have a large demand for nutrients. During the growing season, they need to be provided with nitrogen fertilizer and urea to increase the growth rate of the plants. After the soybeans enter the flowering and fruiting period, they should be sprayed with potassium dihydrogen phosphate to promote the fruit to mature as quickly as possible. Phosphorus and potassium fertilizers can also be buried in the soil to allow the plants to grow better.

3. Disease prevention and control

Northeast soybeans have poor disease resistance. During the breeding process, they must be ventilated regularly to prevent bacterial growth, and the soybeans must be sprayed with carbendazim once a month to eliminate the bacteria on the plants. If soybeans are diseased, the infected plants must be removed in time and quicklime must be sprinkled into the soil for sterilization.
