1. 1. The oil yield and dregs yield of domestic soybeans are 16.5% and 80% respectively, and the oil yield and dregs yield of imported soybeans are 18.5% and 78% respectively. The squeezing profit can be calculated according to the following formula: 1 ton domestic soybean squeezing profit = soybean oil sales price ×0. 165+ soybean meal sales price ×0.80- soybean purchase price-processing fee 1 ton imported soybean squeezing profit = soybean oil sales price × 0./kloc-0+soybean meal sales price.
Judging from the relationship between soybean and soybean meal and the trend of squeezing profit, the inverse relationship between soybean price and squeezing profit is basically established, but the influence of soybean meal on it is relatively limited.
2. In addition, we can also see that cost push is one of the most important reasons for the price increase of soybean meal.
3. Under normal circumstances, the price of soybean meal is relatively stable, and its overall fluctuation range will not be great.
4. The increase of soybean oil price has a good promotion effect on the crushing profit. But the core of squeezing profit still comes from the contribution of soybean meal price share.
5. Because the consumption of soybean oil shows seasonal changes, the production and consumption of its related products also show certain periodicity, and the price of soybean oil also shows certain cyclical fluctuations.
Second, the precautions for planting soybeans
1, providing moisture
Soybean is suitable for growing in humid environment. When planting soybean, it is necessary to provide proper water for plants and keep the soil moist. At the same time, when supplying water to soybeans, it is necessary to pay attention to the amount of watering. Generally, the amount of water should be increased when the soil is dry, and decreased when the soil is wet.
Step 2 supplement nutrition
Soybean has a great demand for nutrients in the growth process, so it is necessary to provide plants with appropriate nutrients to improve the growth speed when maintaining soybeans, and pay attention to the amount of fertilization when providing nutrients to soybeans. Generally speaking, fertilizer can be dissolved in clean water and provided to plants to allow them to absorb more nutrients.
Step 3: Proper lighting
There is a great demand for light during the growth of soybean. Insufficient light will cause soybean leaves to turn yellow and the plants will not bear fruit smoothly. Therefore, when maintaining soybean, it is necessary to provide proper light for normal photosynthesis of plants, keep the leaves green, and let plants bear more fruits.
Second, the nutritional value:
Soybean not only refers to soybeans, but also includes black beans and mung beans. Soybean is rich in nutrition and content. The content of protein is twice that of pork and 2.5 times that of eggs. The content of protein is not only high, but also of good quality. The amino acid composition of soybean protein is similar to that of animal protein, in which the proportion of amino acids is close to the needs of human body and easy to digest and absorb.
