1, base fertilizer
The bean does not need good nutrition during the undeveloped root nodule stage. Therefore, the organic fertilizer and calcium superphosphate should be applied and the fertilizer should be poured into the soil and then ridged. Dwarf varieties have a basal amount of about 80%. Do not add too much nitrogen in the basal fertilizer so as to avoid causing the stems and leaves of the plant to grow young and leggy. For mulching film cultivation, due to the inconvenience of top dressing, the amount of basal fertilizer should be increased as compared with open cultivation.
2, top dressing
Kidney beans are short in dwarf species and can be traced 1-2 times. When the flower buds of the kidney bean begin to differentiate at the seedling stage, 20% to 30% of the thin human feces and urine should be applied in time. Combining irrigation with photosynthetic nutrient film fertilizer at flowering stage can help plants absorb a large amount of light, light, light, compatible with conventional fertilizers, and nutrients to supply plant growth and development to the limit; blooming and scorching stage spraying vegetables and fruits to make fruits and vegetables Improve pollen fertilization quality, strong fruit set rate, promote fruit development, no abnormalities, no shells, no pods, good uniformity, quality, and its high yield.
