The Latest Hyacinth Bean Fertilization Techniques and Methods Tutorial

The hyacinth bean, commonly known as bian dou, is cultivated in both tropical and subtropical regions. Its tender pods are eaten as a vegetable, and its flowers and seeds can be used as medicine. It has the effect of dispelling summer-heat and dampness pathogens and strengthening the spleen to stop diarrhea, and it also has a notable effect of reducing tumors. So how should the hyacinth bean be fertilized when planted? Let's find out together.

1. Base fertilizer

The hyacinth bean is a fertilizer-loving crop, and its growth and development cannot be separated from nutritional support. Before sowing, base fertilizer should be applied together with land preparation. The base fertilizer is mainly organic fertilizer or farmyard manure, generally applied at 2000-3000 kg per mu. When applying farmyard manure, be careful to fully decompose it, so as to avoid the fertilizer fermenting and burning the roots, causing seedling death. After fertilizing, level and harrow the soil finely, then make beds according to the terrain and wait for sowing.

2. Seedling fertilizer

Generally, after sufficient base fertilizer is applied, the hyacinth bean does not need fertilizer before the flowering stage. If the base fertilizer was not applied sufficiently, or the plants are growing weakly, consider applying quick-acting chemical fertilizer or decomposed human feces and urine with irrigation water to promote seedling growth. The hyacinth bean prefers nitrate nitrogen and does not like ammoniacal nitrogen. Applying too much ammoniacal nitrogen fertilizer will inhibit its growth and development, so special attention should be paid when fertilizing.

3. Flower and pod fertilizer

The flower and pod stage is the period with the greatest demand for fertilizer and water. At this time, fertilization is generally carried out together with watering. When applying fertilizer at the flowering stage, urea, compound fertilizer and human feces and urine are mostly used. When the lower inflorescences set pods, generally water once every 15 days and topdress once, applying 10 kg of ternary compound fertilizer or 100 kg of human feces and urine per mu each time; during the pod-setting stage of the middle inflorescences, generally water and topdress once every 8-10 days, applying 7-8 kg of urea with irrigation water per mu each time; during the flowering stage of the upper inflorescences and the stage of the side branches flowering again and setting pods, generally water and topdress once every 10 days, applying 5 kg each of urea and potassium sulfate with irrigation water per mu each time. At the same time, from the late pod-setting stage, ventilation and light penetration should be improved. Old leaves and yellow leaves in the middle and lower parts should be removed in time, and some leaves in overly dense stem and leaf areas should be thinned out, and late-emerging tender buds should be pinched off.

4. Harvest fertilizer

15-16 days after the hyacinth bean flowers, when the pods grow large and good, the fresh weight meets the standard, and this is the period with the best commercial value. At this time, harvest them. When picking, be careful to protect these flower buds. After picking the first crop of pods, the retained flower buds will accelerate their development, flower and set a second crop of pods. At the same time, after each picking, fertilize once to set a second crop of pods.
