Banana fertilizer types and fertilization methods

① fertilizer types . Banana applying fertilizer organic fertilizer and inorganic fertilizer of two categories.

Organic fertilizer. Organic fertilizer is organic fertilizer, including human beings and livestock manure , poultry, animal waste , crop stems and dross , ash , green manure and other organic material of plants and animals , as well as river mud , pond scum , swim alluvial mud , contains a more comprehensive nutrients. After the organic fertilizer can improve the physical properties of the soil , improve soil drainage and ventilation performance increase by microbial decomposition of soil humus and nutrients. Organic fertilizer commonly used as a newly planted banana basal or early spring fertilizer, too cold fat , easily decomposed bran cake can be used as fertilizer or flower bud seedling fertilizer.

Inorganic fertilizer . Mast mostly inorganic chemical fertilizers , elemental content, can be dissolved in water or weak acid inside , easily absorbed and used bananas , fertilizer is high and fast, very easy to use . But some improper use of inorganic fertilizers can cause soil compaction or too acid or alkaline , inorganic fertilizer and organic manure , you can overcome these problems. Bananas used inorganic fertilizers , urea nitrogen fertilizer , ammonium sulfate , ammonium bicarbonate, ammonia , phosphate has superphosphate, calcium magnesium phosphate, phosphate and phosphate powder defluorinated , Potash potassium sulfate, potassium chloride . General fertilizer nitrogen, phosphorus and potassium , the ratio is generally 15:15:15 , Guangzhou Huangpu Canadian foreign plant bananas BB fertilizer production of nitrogen, phosphorus and potassium ratio of 1:0.2:1.33 .

② fertilization methods . There are two types of banana fertilization is rhizosphere fertilization and foliar application . In rhizosphere fertilizer -based, foliar supplement.

Rhizosphere separable liquid fertilizer facilities and dry facilities, and dry Shi was divided applicator , fertilizing and Summer .

Liquid applied . Liquid applied with a water soluble fertilizer diluted will be applied for those easily dissolved instant -use of organic fertilizer bran bread , and livestock etc. to water or human, animal urine, rotten ret only with maturity , dissolved into a paste shall immediately after applying thin soil cover . Liquid manure applied benefit is easy to contact with roots , easily absorbed without causing root , drought Shihai from irrigation effect.

Applicator . Fertilizer applicator is to sprinkle on Qimian , generally after the rainy season , when the soil is also more humid . Mostly dry soil should not dry weather applicator , if dry weather sunny Qimian applicator must first leaching ( irrigation ) wet . Applicator to spread evenly , Shi Bi best shower water once . Applicator has the advantage of saving labor, to expand the absorbing surface , quickly see the fertilizer , but the application of the loss of roots and easily hurt improper waste, especially from May to July banana root easily exposed soil , do you want to control the fertilizer according to the degree .

Fertilizing . Fertilizing in banana plants from 30 to 100 cm digging , hole depth of 15 to 23 cm ( size depending on how much fertilizer may be ) , the fertilizer into the cavity and covered with soil . Yuhan days shall be sufficiently wet to facilitate manure decomposition melt. Benefits of fertilizing is to prevent loss of fertilizer , manure hurt less, but absorption is narrow , fertilizer more slowly and spend more workers . pressure water sprayer Generally too cold for spring fertilizer and manure .

Summer . Summer in the banana plants from 30 to 100 cm 2 1 small arcuate groove , a width of 15 to 25 cm , length 35 to 50 cm, depth of 8 to 15 cm , the fertilizer is applied uniformly in the trench , and soil . Summer In addition to the benefits of fat loss and prevent injuries less fertilizer , the absorbing surface over fertilizing wide, fertilizer than fertilizing fast, but also more flower workers . Generally used for spring fertilizer, manure and too cold autumn fat , not in use from May to July , when the banana plants due to fine roots across the park and out of the ground , ditching easily hurt fine roots .

Banana foliage spray is sprayed to the foliage or fruit surface low according to the degree of liquid fertilizer. The advantage is easily foliar fertilizer leaves or fruit directly . Rapid absorption , replenish nutrition, growth and development to meet the bananas on nutrient needs, especially to the young fruit bud development stage requires a lot of nutrients through the foliage spray can replenish the nutrients it needs , to improve the yield and quality of banana plays an important role . On the other hand , foliar spraying , fruit leaven , fertilizer absorption rate can be as high as 90 %, significantly higher than the rhizosphere fertilization. However, hand pump sprayers there are shortcomings foliage spray , mainly small amount of fertilizer each time , you need to repeatedly administered , flower workers more .
