Chili is an indispensable seasoning and vegetable in our daily diet. For those who want to grow chili, a reasonable fertilization method is one of the important factors for achieving high yields and vigorous growth. Do chilis like fertilizer? What kind of fertilizer do they prefer? This article will introduce the relevant knowledge.
I. Growth Characteristics of Chili
Chili is a tropical crop, heat-tolerant and sun-loving, with a suitable temperature range of 20°C-32°C. At the same time, it has another characteristic: it loves and tolerates fertilizer well. During its growth, chili needs to absorb a large amount of nutrients to ensure its high yield and growth momentum.
II. Common Fertilizer Types
1. Organic fertilizer: Organic fertilizer refers to fertilizer derived from animals or plants, such as livestock and poultry manure, composted manure, and bird droppings, which has a significant promoting effect on chili growth.
2. Chemical fertilizer: Chemical fertilizer refers to chemically synthesized fertilizers, mainly including three major types: nitrogen, phosphorus, and potassium fertilizers. Among them, nitrogen fertilizer is suitable for promoting robust plant growth, phosphorus fertilizer is suitable for improving fruit quality, and potassium fertilizer is suitable for increasing yield.
III. Fertilization Methods for Different Growth Stages
1. Seedling stage: You can use top-dressing at the base or spray with an organic fertilizer solution.
2. Flowering stage: You can spray with a multi-element compound fertilizer or an NPK compound fertilizer.
3. Fruit ripening stage: You can apply a high-phosphorus compound fertilizer or diammonium phosphate, etc.
IV. Benefits of Using Organic Fertilizer
Organic fertilizer can not only provide the nutrients needed by plants but also improve soil structure and increase the soil's water retention capacity. In addition, organic fertilizer can promote the growth and reproduction of microorganisms, enhancing soil vitality.
V. Precautions for Using Chemical Fertilizer
1. The application of chemical fertilizer should be moderate; excessive amounts will lead to excessive plant growth, affecting fruit quality.
2. Chemical fertilizer should be applied when the soil is moist to avoid affecting its absorption efficiency.
3. The timing of chemical fertilizer application should be appropriate; it should not be applied after rain or during high-temperature weather.
VI. Selection of Fertilization Time
During its growth, chili requires a gradual increase in fertilizer application, and the appropriate fertilization time should be chosen according to different growth stages. Generally speaking, spring and summer are the peak growth periods for chili, and attention should be paid to fertilization during this time.
VII. Ratio of Base Fertilizer to Top-dressing
In the process of chili planting, both base fertilizer and top-dressing are important. Base fertilizer provides basic nutrients for the entire growth process, while top-dressing provides timely supplementary nutrients for the plants. According to actual conditions, the ratio of base fertilizer to top-dressing can be controlled at 2:1 or 3:1.
VIII. Common Fertilization Tips
1. Conduct regular observations to promptly detect the plant's growth status.
2. Avoid excessive use of chemical fertilizer and choose the application amount rationally.
3. Pay attention to fertilization time and methods.
IX. How to Make Organic Fertilizer
1. Livestock and poultry manure: Pile chicken manure, duck manure, pig manure, etc., together to decompose, and you can make organic fertilizer.
2. Compost: Mix organic materials such as household garbage and fallen leaves together to decompose, and you can also make organic fertilizer.
3. Bird droppings: Soak bird droppings in water to make bird manure water, which can then be sprayed.
X. How to Choose Chemical Fertilizer
When choosing chemical fertilizer, you should select the appropriate fertilizer based on the nutrients the plant needs. Generally, nitrogen fertilizer is suitable for improving plant growth, phosphorus fertilizer is suitable for improving fruit quality, and potassium fertilizer is suitable for increasing yield.
XI. Ratio of Organic to Chemical Fertilizer
Depending on the plant and growth stage, the ratio of organic to chemical fertilizer will vary. Generally, in the early growth stage, organic fertilizer should be the main component, supplemented with a small amount of chemical fertilizer to promote robust plant growth. In the middle and later stages, chemical fertilizer should be the main component, supplemented with a small amount of organic fertilizer to improve fruit quality.
XII. Application Methods for Organic Fertilizer
1. Direct application: Spread the organic fertilizer evenly on the soil surface around the plants.
2. Hole application: Dig the organic fertilizer into the center of the soil and then fill the soil back.
3. Liquid fertilizer application: Dissolve the organic fertilizer thoroughly in water, then spray it on the plant leaves and soil surface with a sprayer.
XIII. Application Methods for Chemical Fertilizer
1. Base top-dressing: Mix the chemical fertilizer evenly into the entire soil layer before planting chili.
2. Foliar spray: Dissolve the chemical fertilizer evenly in water and spray it evenly on the chili leaves with a sprayer.
3. Root application: Dissolve the chemical fertilizer evenly in water and use a syringe to directly inject it into the roots.
XIV. Calculation Method for Chemical Fertilizer Application Amount
There are mainly two methods for calculating the amount of chemical fertilizer to apply: one is based on the nutrient requirements of the plant, and the other is based on soil type and fertilization time.
