Prevention and control measures of flower and pod shedding of adzuki bean

In the process of planting adzuki bean, flowers and pods often fall off, which has a decisive impact on the high yield of adzuki bean, but flowers and pods can be avoided. The following editor brings you the prevention and control techniques of adzuki bean flower and pod shedding. Let's learn about it.

1. Topdressing according to the ground

The shedding of flowers and pods of adzuki bean may be caused by insufficient nutrients during flowering and pod setting, so fertilizer can be applied once at the early flowering stage to supplement nutrients and reduce the shedding of flowers and pods. Generally apply urea 5 kg or ammonium sulfate 10 kg per mu, pay attention to the method of fertilization, should not directly contact the root system, so as to avoid burns.

2. Extra-root fertilization

In addition to the normal root fertilization, it can also be fertilized outside the root. In the flowering and pod stage, 0.5 kg of urea, 1.5 kg of calcium superphosphate, 0.25 kg of potassium sulfate and 25 g of borax are mixed with 50 kg of water per mu. After the extract is extracted, sprayed on the leaves with a sprayer, the foliar fertilizer should be sprayed on cloudy or sunny days after 4 p. M., which is beneficial to flower preservation, pod and grain growth, and can also reduce shrunken grains. Increasing single grain weight and extra-root fertilization can be combined with pest control and improve labor efficiency.

3. Chemical regulation

Paclobutrazol can be used to strengthen plants, increase branches, shape ideal plant type and increase yield in soybeans. Adzuki bean can also be chemically controlled by multiple frustrations to reduce flower and pod shedding. Generally, 15% paclobutrazol is sprayed at the early flowering stage with 20 grams of paclobutrazol and 50 kilograms of water. It can improve the plant type of soybean, prolong the functional period of leaves, improve the ventilation and light transmission conditions in the field, and optimize the growth environment of soybean, so as to promote growth and reduce shedding.

4. Pay attention to drought prevention and drainage

Adzuki bean from pre-flowering to podding period is the fastest and fastest period to absorb water in the whole growth period, at this time, if the soil moisture is too low, it will affect the expansion of beans, so timely irrigation is needed. Generally every 5-7 days irrigation, continuous irrigation 2-3 times, remember flood irrigation, adzuki bean is a poor waterlogging tolerance, stagnant water is very easy to cause falling flowers and pods, so we should pay attention to drainage, so as not to produce waterlogging damage.
