How to irrigate and fertilize bananas in each stage?

How to irrigate and fertilize bananas at various stages? Please give an introduction to banana irrigation and fertilization at various stages can refer to the following methods: 1, seedling stage. Banana seedlings, especially tissue culture seedlings, seedlings that need fertilizer and afraid of heavy fertilizer. Within 3 months after planting, the principle of "frequent application and thin application" shall be adopted. Fertilization is started when new leaves are opened 10 days after planting, and the banana head is showered with 0.1%-0.2% ternary compound fertilizer water or lighter decomposed manure water, 1 kg-2 kg per plant, once every 5 days. The concentration and amount of liquid fertilizer can be slightly increased in the third month after planting, and a small amount of urea and potassium fertilizer can be added, and it should be showered once every 10-15 days. 2. Middle term. When growing to 18-30 leaves, the fertilizer requirement increases. However, too much fertilizer once will also hurt the roots, and fertilizer should be applied once every 10 days. 0.5 - 1 kg bran fertilizer (or 0.3-0.6 kg multiple compound fertilizer), 0.1 - 0.2 kg potassium chloride and 50-100 g urea can be used for each plant each time. In rainy days, circular shallow ditches are opened along the banana drip line, and in dry days, 30 kg-40 kg of water is added to sprinkle along the drip line, and soil is covered in time after application. If banana growth is found to be less prosperous, foliar fertilizer containing organic matter can be sprayed, such as Jiamu Harvest Regulator 1-2 times to promote growth. 3. Pregnant bud stage (31-44 leaves). Banana fertilizer needs the most, every 20-25 days, each plant each time apply urea 0.1 kg, potassium chloride 0.2 kg, peanut bran 0.5 kg-1 kg (or multi-element compound fertilizer 0.5 kg), after the rain irrigation, and keep the soil moist. 4. After bud extraction. After budding, 0.1kg-0.2kg ternary compound fertilizer, 0.2kg-0.3kg bran fertilizer and 0.1kg potassium fertilizer can be applied to each plant every time. After rain or irrigation, they can be applied. Before bagging, spray 2-3 times (every 5 days) with 1000 times solution of Jiamu Fengshou (or Shengduo Su), which can not only make the fruit plump and bright, but also improve the cold resistance and disease resistance. But avoid excessive spraying hormone foliar fertilizer, so as not to affect the quality, reduce cold resistance. Click for more banana growing techniques Click for more fruit growing techniques
