Green beans can be grown in various regions across the country, and proper fertilization plays a crucial role in their growth, development, and yield during the cultivation process. So, what is the best fertilizer for green beans? Let's explore it together.
What is the Best Fertilizer for Green Beans?
1. Nutrient Requirements:
Green beans require nutrients such as nitrogen, phosphorus, potassium, etc. It is advisable to choose appropriate doses of compound fertilizer, diammonium phosphate, urea, potassium sulfate, and other fertilizers to meet the growth and development needs of green bean plants.
2. Fertilization Methods:
a. Basal Fertilization:
It is recommended to use fully decomposed organic fertilizer for basal fertilization, avoiding excessive use of nitrogen fertilizer as seed fertilizer to prevent seed rot. Typically, 1000-1500 kilograms of high-quality organic fertilizer per mu can be used, along with 1-2 kilograms of microbial bacterial fertilizer, which can improve the soil.
b. Topdressing:
Green beans have moderate fertilizer requirements, and topdressing should follow the principle of "emphasis on basal fertilization and supplementary topdressing". Thinly apply nitrogen fertilizer during seedling stage, and increase the concentration appropriately as the plants grow. Generally, 10-15 kilograms of compound fertilizer and 0.1-0.2 kilograms of microbial bacterial fertilizer per mu can be applied, applied with water.
c. Foliar Fertilization:
During the flowering period and pod setting period, foliar spray with urea, ammonium sulfate, calcium superphosphate leachate, and other binding powder-type microbial bacterial agents. Typically, 1-2 kilograms of urea and 1-2 kilograms of potassium dihydrogen phosphate per mu, mixed with 40-50 kilograms of water.
Precautions:
1. When planting green beans, fertilization can be done through methods such as direct seeding and irrigation. Direct seeding can mix fertilizers with soil and apply them through irrigation, while irrigation method involves fertilization through irrigation systems.
2. The amount of fertilizer, types of nutrients, and timing of fertilization for green beans should be adapted to local conditions. Generally, excessive fertilization should be avoided to prevent damage to green bean plants, and the amount of fertilization should be adjusted timely based on factors such as soil fertility, geographical environment, and growth status.
This concludes the introduction to the best fertilization practices for green beans. Green beans are leguminous crops with continuous flowering and podding. They have high nutrient requirements. Insufficient nutrient supply can lead to irregular flowering and podding, reduced yield, and inferior quality. Therefore, growers should pay attention to the fertilization of green beans.
