Fertilization method of colorful Pepper

Colorful pepper, also known as Chaotian pepper, colorful pepper, is a variety of pepper, the fruit is clustered at the top of the branch, the same fruit has yellow, red, purple, green and other colors. The growth of colorful peppers needs adequate nutrition, so fertilization is essential, so how to fertilize colorful peppers? Come and have a look with the editor.

1. Characteristics of fertilizer requirement

Colorful pepper has higher nutritional requirements, with an average of 4.2kg of pure nitrogen, 1.1kg of phosphorus pentoxide and 6.5kg of potassium oxide for every 1000 kg of fruit, as well as an appropriate amount of calcium fertilizer and pepper Zhuangtiling. Therefore, when planting, fertilization is mainly phosphorus and potassium fertilizer, and nitrogen fertilizer is mainly used in the early growth stage, which promotes plant growth, makes it more branched, and lays the foundation for the results. In the later stage, potash fertilizer was mainly used to promote fruit expansion and improve yield and quality.

2. Base fertilizer

It is necessary to fertilize the soil before planting, to ensure that the soil is loose and ventilated, and to create a suitable environment for the growth and development of seedling root system. Combined with soil preparation, 4500 kg of organic fertilizer, 150kg of bio-organic compound fertilizer, 50kg of urea, 25kg of superphosphate, 50kg of potassium sulfate and 100kg of calcium fertilizer were applied per mu. Mix it evenly and apply it, and then turn it into the soil, it is necessary to pay attention to avoid direct contact between the root system and fertilizer, so as to avoid root system burns.

3. Squatting seedling fertilizer

After the introduction of the seedling stage, when the first ear grew to the size of walnut, the first topdressing was carried out, applying 5 kg of pure nitrogen and 6 kg of potassium oxide per mu. At this time, plant vegetative growth and reproductive growth go hand in hand, so fertilization is mainly nitrogen and potassium fertilizer, in order to promote branch and leaf growth and fruit expansion, can significantly increase yield.

4. Harvest fertilizer

When the first ear fruit is about to be harvested, the second layer fruit and the third layer fruit continue to expand, and the third layer fruit is falling flowers and setting fruit, this is the peak period of plant fertilizer demand, and the second fertilizer should be re-applied, applying 6 kg of pure nitrogen and 7 kg of potassium oxide per mu. The third blessing was given half a month later, and the amount of fertilizer applied was equal to that of the second time. 15-20 days later, the fourth fertilizer was applied, and the amount of fertilizer applied was the same as that of the first time.
