Crops are related to the production cycle, which month is suitable for frying. In addition, it is related to the supply and demand cycle of varieties. For example, wheat 90 1 905,909. The annual planting area of new crops has great influence on 1; May is the time when wheat is green and yellow; However, the 80-day post-harvest of wheat will affect the internal quality, and then affect the number of warehouse receipts that can be registered, thus affecting the September contract. These are all places that can be used and hyped. Compared with other months, there are more hype factors. The growth of wheat will not change much from 1 to March. In addition, if the monthly interval is too short, such as 1, March, the time interval is too short, and the capital flow is inconvenient. For example, 1 the delivery month is approaching, and the funds are changed to March. In such a short time, it is almost too late to start a decent market, and near February, the deposit will be increased one month before the delivery month, reducing the efficiency of capital utilization. It's better to switch to May, which is plenty of time.

Like other agricultural products, we can try to understand them from the perspective of growth and production cycle.
