Beans are mainly broadcasted, but according to the needs of early ripening, some also use seedling transplanting. We introduced basal beans fertilization methods in terms of basal fertilizer and top dressing. Take the example of live direct fertilization in autumn.

The basal bean bean root nodule, which is symbiotic with the kidney beans, can fix nitrogen in the air, so that nitrogen can be converted into nitrogen that can be absorbed by the kidney beans, so nitrogen fertilizer can be used less frequently. In the undeveloped seedling stage, quick-acting nutrients are required. Therefore, it is necessary to apply 2300-3500 kg per mu of decomposed organic fertilizer, 30 kg of superphosphate and 10 kg of potassium sulfate (where 100 kg of grass and wood ash can be used instead of potassium sulfate). The fertilizer is then 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.

Top-fermented bean is one of the most favorite fertilizers in leguminous vegetables. Dwarf species have short scarring time and can recover 1-2 times of fat. At the seedling stage, when the kidney bean begins flower bud differentiation, it is timely to apply 20%-30% of thin human fecal urine to 1500 kg per mu, add 4-5 kg ​​of potassium sulfate and superphosphate, and combine irrigation with fertilizer to dilute wastewater during flowering. For good and add 10 kg of potassium fertilizer; flowering and poding period, 50% of manure urine can be used per acre 2500-5000 kg, can also use nitrogen, phosphorus, potassium compound fertilizer 10-15 kg per acre, with fertilizer after watering.
