1, fertilizer

Plum beans high yield, the greater the demand for fertilizer, China's fertilizer is not enough, may result in the non-flowering, but the flowering period when the fertilizer is too much will result in the prolongation of the branches and leaves, resulting in the flowering of the nutrients required for the lack of flowering, resulting in the non-flowering. Therefore, in the plum bean fertilizer management should pay attention to the combination of control and promotion, appropriate adjustment of fertilizer, so that the plum bean nutritional growth and reproductive growth balance, to achieve both non-expansive growth and the purpose of early flowering. Generally in the seedling period when the appropriate control of fertilizer, bottom fertilizer to Bika microbial fungi and organic fertilizer based on the flowering period to increase the amount of watering, increase the application of organic fertilizer.

2, temperature

Plum beans are heat-resistant but not frost-resistant, in the flowering and podding period of the appropriate temperature of 25-28 degrees, when the temperature is higher than 35 degrees, plum beans will be the phenomenon of early decline, resulting in the fall of flowers and pods more, and lower than 10 degrees, the flower buds are delayed differentiation. So pay attention to temperature regulation, it is best to ensure that the right time, shed cultivation should pay attention to temperature regulation, high temperature when open shed film, ventilation, reduce the temperature, low temperature when covered with grass curtains, warming package warming, to promote its normal growth.

3, light

Doujiao for the length of light there are two responses, one is not strict requirements for sunshine, while the other is more strict, suitable for cultivation in a short sunshine environment. If the planting of this short sun varieties of beans, planting the environment of the length of light is also relatively long, there will often be stem and vine prolongation, delayed flowering and pods and reduce the phenomenon, for this phenomenon should be appropriate shade, is conducive to the early flowering of its pods.

4, their own reasons

Meidou in the hot season, when the first crop after the peak period, there is often the phenomenon of ambush, then the plant will appear flowering pods of the phenomenon of great reduction. If it is because of the cause of ambrosia, then it is necessary to strengthen the fertilizer management, the plant will be from the lower middle of the leaf axils of a large number of lateral trails occur, and draw out inflorescences, a large number of flowers and pods, to restore the vitality and the emergence of the second peak of production.
