When is the flowering period of wheat?

Wheat is a gramineous plant, which is widely planted in the world. There is a long history of planting wheat in the two river basins, and China is also one of the countries that planted wheat earlier in the world.

The flowering time of wheat is different. Generally, it takes 2-3 months to sow in March-April and blossom in mid-June. Winter wheat is usually sown in August-65438+February in autumn, and it takes more than five months to blossom in May of the following year. The flowering period of wheat generally lasts about one month, and the flowering time of a single flower is only 10-20 minutes.

Wheat flowering maintenance

In the field management of wheat flowering period, there are mainly prevention and control of scab and midge. Some areas should be watered in time to keep the soil moist because of drought, but there should be no water accumulation, otherwise it will affect flowering, and sufficient light should be provided for maintenance.

Flowering and watering

When wheat is exposed to high temperature and dry environment during flowering, it should be watered in time, but the amount of water should not be too large, otherwise it will affect the fertilization and fruiting of wheat. It is best to water before 8 o'clock in the evening or in the morning. In case of continuous rainy days, water should be drained in time to reduce the humidity in the field and reduce the occurrence of scab.

Fertilization at flowering stage

The absorption and utilization rate of nitrogen and phosphorus in wheat at flowering stage is slightly different, but the absorption and utilization rate of potassium is relatively large. Wheat grows slowly before turning green, and the demand for fertilizers such as nitrogen, phosphorus and potassium is small. The absorption of nitrogen, phosphorus and potassium from jointing stage to flowering stage is large, so topdressing base fertilizer and topdressing in time, especially at jointing stage, is the key to high yield of wheat.

Flowering pruning

There is no need to prune the flowering period of wheat, because the flowering period of wheat is short. After the flowers wither, they will start heading and fruiting, and just wait for the wheat flowers to fall off naturally.

Post-treatment of wheat flowering period

Appropriate amount of nitrogen and potassium nutrition can be applied to wheat after flowering to make its leaves green, improve photosynthetic production in the later stage, ensure grain filling and increase grain weight.
