The demand for nutrients by bananas generally increases with the leaf stage. The growth and development of bananas during the 18 to 40 leaf stage play a decisive role in the production and quality of bananas, so this period is an important fertilization period for bananas. This period can be divided into two periods of vegetative growth and flower bud differentiation, and most of the fertilizer should be concentrated in these two periods.

1 During the late period of vegetative growth (18-29 leaf stages), 3 to 5 months after the spring planting of bananas, 5 to 9 months after the planting of the summer and autumn planting bananas and the hemp roots. From the perspective of the leaf shape, this period consisted of freshly drawn leaves (the new leaves that had just been extracted were mostly bent like a tiger's tail) until they entered one or two big leaves. This period is in the period of vegetative growth, with very strong requirements for nutrients, the most sensitive response, and the growth and development of banana plants is determined by the availability of fertilizers. If the heavy fertilizer is applied at this time, the banana plants will receive sufficient nutrients. The long-leaved and long-stemmed banana plants perform efficient assimilation and accumulate large amounts of organic matter, which lays a solid foundation for the differentiation of flower buds in the next stage.
2 Flower bud differentiation period (30-40 leaf stage), 5 to 7 months after the spring planting banana planting, 9 to 11 months after the planting of the summer and planting bananas and the hemp roots and bananas, and from the leaf shape, this period consists of 1-2% of the large-leaved sunflower blade with a short round, the leaf pitch turns from the most sparse, and the speed of the leaf drawing is slow; from the stem, the pseudo-stem develops to the thickest, and the bulbs begin to expose the ground and form an altar shape. Seen from the suction buds, it has entered the budding period. This period is in the process of flower bud differentiation of reproductive growth, and requires a lot of nutrients for the growth of young ears to form spikes with long spikes and large fruits. According to foreign studies, when the flower buds differentiate into flower buds at the later stage of vegetative growth, the nitrogen content in the leaves suddenly drops because at this time a large amount of nitrogen is needed to supply the flower buds for differentiation. When the root system absorbs nitrogen from the soil and it is not enough, nitrogen has to be Transferred from leaves, stems and other tissues and organs. Heavy fertilizer at this time can promote maximum assimilation of leaves, and create more organic matter for the formation and growth of young ears.
