Banana fertilization technology

Banana is a kind of large herbaceous fruit often cultivated in tropical areas. it mainly depends on the sucking roots germinated at the rhizome to continue to propagate. fertilization is the top priority for planting bananas. bananas have higher requirements for soil properties, not only for high demand for fertilizer. However, fertilizer is the main condition for improving soil properties. So today I decided to talk about how to fertilize bananas, so as to improve the soil and make bananas grow better.

First, the characteristics of fertilizer demand

Banana roots are mostly whisker roots, there is no main root, all the roots are about the same degree, so it will form a horizontal root distribution surface. So do not apply fertilizer too deep, probably in the range of 10 to 15 centimeters. Since they are all fibrous roots and take root after budding, the concentration of fertilization should be low to avoid root damage. Generally speaking, it is best to apply mild fertilizer with water as solution. The amount of fertilizer used is roughly the same as that of potassium fertilizer, followed by nitrogen fertilizer, calcium, magnesium and phosphorus.

II. Fertilization

1. Base fertilizer

Base fertilizer can generally use compound fertilizer, can also apply their own formula of compound fertilizer, which can add calcium, magnesium, phosphorus and other trace fertilizers. It is usually applied by burrowing or digging a trench next to the plant. About half a kilogram of fertilizer per plant, the ditch can calculate how many trees are evenly scattered in the ditch, the depth is about 7 centimeters, must be mixed with soil, so as not to hurt the roots.

two。 Vegetative growth period

Fertilizing during the vegetative growth period is about when there are about 30 leaves. It is the prosperous period of the plant, which needs to apply heavy fertilizer to promote the plant growth and long leaves, which is the basis for the differentiation of flowers and leaves. At this time, a large amount of farm manure is needed to provide continuous nutrition.

3. Flower bud differentiation stage

It is about when there are more than 30 leaves and 40 leaves. It is an important period of flower bud differentiation. A large amount of nitrogen is needed at this time, and if it is not replenished, the nitrogen content of the leaf and stem will be converted to the growth of the flower ear. Therefore, enough nitrogen fertilizer must be added in time so that the leaves can maintain normal photosynthesis to provide nutrients.

Bananas need a lot of fertilizer, but the root system is weak, fertilization is generally in addition to a few important periods, the implementation of thin fertilizer application method. No matter how good the fertilizer is, it should be mixed with irrigation. It is beneficial to absorption without harming the roots. Attention must be paid to doing a good job in this series of work, so that the output can be guaranteed.
