1. Base fertilizer
Kidney bean needs quick-acting nutrients at the seedling stage when the nodule is not well developed, so it is necessary to apply rotted organic fertilizer and superphosphate, turn the fertilizer into the soil, and then ridge. The amount of base fertilizer for dwarf varieties is about 80% of vine growth. Do not add too much nitrogen fertilizer in the base fertilizer, so as not to cause the young and long stem and leaf tissue of the plant. For the cultivation covered with plastic film, the amount of basal fertilizer should be increased appropriately compared with open cultivation because of inconvenient top dressing.
2. Top dressing
Beans have a short pod setting time in dwarf species, and can be used for 1-2 fertilizers. At the seedling stage, when kidney bean begins to differentiate into flower buds, 20% -30% of the thin human feces should be timely applied. Combined with irrigation and application of photosynthetic nutrient film fertilizer at the flowering stage can help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers, and nutrients to provide plant growth and development to the limit; spraying vegetables and fruits to strengthen the fruits and vegetables Enhance the quality of pollen fertilization, strong fruit set rate, promote fruit development, no deformity, no empty shells, no grains, good uniformity, quality improvement, and continuous high yield.
