Soil testing and formulated fertilization method for improving yield of bananas

Abstract

The invention discloses a soil testing and formulated fertilization method for improving the yield of bananas. The method comprises the following steps: (1) selecting sampling places with different soil types; (2) collecting soil and leaf samples in selected sampling places; (3) detecting the content of macronutrient, medium nutrient and trace nutrient elements in the soil and leaf samples; (4) determining the target yield of the unit area of bananas according to the growing characteristics and yield situation of different banana varieties in a planting area, and calculating the absorption capacity per unit area yield and fertilizer utilization; (5) calculating the total amount of macronutrient, medium nutrient and trace nutrient elements applied to soil in current season; and (6) determining the type, dosage and method for applying fertilizer in different developing periods according to the fertilizer requirement law of bananas. Compared with local experience fertilization, the scientific and reasonable fertilizer formula and fertilization method have the advantages that all nutrition essential to each developing period of bananas can be supplied, occurrence of diseases and insectpests can be effectively inhibited, and the aim of truly saving cost, synergizing and increasing yield and income can be achieved.

Description

technical field [0001] The invention relates to a fertilization method, in particular to a soil testing formula fertilization method for increasing banana yield. Background technique [0002] Banana is a famous tropical and subtropical fruit. In 2017, my country's banana harvest area was 446,000 hectares, and its output reached 13.272 million tons, accounting for 9.3% of the world's total banana production, making it the second largest banana producer in the world. The soil types in South China are complex, including brick red soil, red red soil, alluvial soil, yellow loam, etc. Bananas are grown on different types of land, and the requirements for fertilization techniques are quite different. Bananas also have certain rules and proportions for their fertilizer needs. The soil quality and nutrient content are different, and the proportion of fertilization should be adjusted accordingly. At present, in banana production, the fertilization technology is relatively blind, main...

AI Technical Summary

Problems solved by technology

At present, in banana production, the fertilization technology is relatively blind, mainly manifested in the insufficient application of organic fertilizers, the unreasonable ratio of nitrogen, phosphorus and potassium, only paying attention to the application of macronutrients and ignoring the application of medium and micronutrients, and the period of fertilization does not match the nutrient requirements of different growth stages of bananas.

At present, the commonly used fertilizers in banana production areas are inorganic compound fertilizers. After being applied to the soil, nutrients are easily lost with irrigation water. The utilization rate of fertilizers is very low, and the amount of fertilizers is not recommended according to banana production areas with different soil types. Therefore, The per unit yield of bananas in my country is far below the average level of countries such as Asia-Pacific and Latin America
