The beans are mainly broadcast, but according to the needs of early maturity cultivation, some also use seedling transplanting. We introduce the fertilization methods of kidney beans in terms of base fertilizer and topdressing. Take the live broadcast of fertilization in autumn as an example.
The base fertilizer bean is in the nodule (the rhizobium symbiotic with the bean can fix the nitrogen in the air, so that the nitrogen can be converted into nitrogen which can be absorbed by the bean, so that the nitrogen fertilizer can be applied less), the undeveloped seedling stage needs quick-acting nutrients, Therefore, it is necessary to apply the decomposed organic fertilizer 2500-3500 kg per mu, 30 kg of superphosphate, 10 kg of potassium sulfate (the potassium sulfate in the area with grass ash can be replaced by 100 kg of grass ash), and the fertilizer is turned into the soil and then ridged. The number of base fertilizers for dwarf varieties is about 80% of that of vines. Do not add too much nitrogen fertilizer to the base fertilizer to avoid the plant stems and leaves being young and long. For mulching cultivation, due to inconvenient topdressing, the amount of base fertilizer is increased more than that in open field cultivation.
Topdressing beans are the most fertile of legumes. Short-lived pods have a short poding time and can be traced 1-2 times. When the bean sprouts start flower bud differentiation in the seedling stage, 20%-30% of the thin human excrement should be applied in time to 1500 kg per mu, and 4-5 kg ​​of potassium sulfate and superphosphate should be added; the flowering period combined with irrigation and topdressing, with diluted manure For the sake of good and add 10 kg of potash; in the flowering and pod-forming period, 50% of human and animal excrement can be applied to 2500-5000 kg per mu, or 10-15 kg per mu of nitrogen, phosphorus and potassium compound fertilizer can be used, and watering can be applied after fertilization.
