The latest key points of soybean florescence management

After flowering, soybean enters a period of alternating vegetative growth and reproductive growth, when the temperature is high, the light is strong, the plant growth rate is fast, and it is easy to cause lodging due to overgrowth. So how to manage soybeans at flowering stage? Let's take a look.

1. Cultivate the soil by ploughing.

Soybean after flowering has reached the need to absorb nutrients, at this time to carry out anti-lodging treatment, then it is necessary to carry out mid-tillage soil treatment. It is necessary to plough soybean before blooming and sealing ridges, maintain good soil permeability, facilitate root development, increase lateral roots, make individual development and population structure want to adapt, achieve this robust development, achieve the purpose of lodging resistance and yield increase.

2. Drainage and irrigation

The flowering period of soybean is the critical period of water demand. If the soil moisture exceeds the field capacity by 80%, it means that the growth and development of soybean will be affected, so it is necessary to eliminate stagnant water in the field in time after heavy rain and reduce soil moisture and air humidity. Make the plant grow normally. The vegetative growth reaches the peak at the end of flowering, and the metabolism is exuberant, at this time, if the soil water content is low, it will cause a large number of flowers and pods, so it is necessary to clean up according to the soil dry and wet and watering in time.

3. Topdressing

The flowering stage needs to consume a lot of nutrients. If there is a lack of fertilizer at the flowering stage, there will be fewer flowers and pods, more shedding, light leaves, weak plants and other phenomena in the middle and later growth period, which is an obvious symptom of de-fatting. At this time, it is necessary to topdressing in time to maintain soil nutrients, but soil fertilization, the effect is slow, so it can be carried out with extra-root fertilization, the effect is better.

4. Spray

Soybean is weak in resistance to the external environment at flowering stage, and at this time, spraying pesticides will inevitably hurt pollen and stigma, make buds fall off, increase blighted grains, and often lead to a 10% reduction in yield. 15%. If diseases and insect pests occur during the flowering period and medication is necessary, it is best to do so after 4 p.m., and the dosage and concentration should be strictly controlled at the same time.

The above is the introduction of soybean flowering management points, hope to help you, want to know more related knowledge, please follow us.
