The latest fertilization method of potted pepper

Pepper absorbs nutrients at different growth stages, in which nitrogen steadily increases with the development of fruit, fruit yield and absorption increase; the absorption of phosphorus varies less at different stages; the absorption of potassium is less at the early stage of growth and increases significantly from the early stage of fruit harvest to the end; the absorption of calcium also increases with the growth period, if the supply of calcium is insufficient during fruit development, navel rot is easy to occur. The absorption of magnesium is high in the peak period of fruit harvest.

If you want your chili to bear more fruit, you not only need to apply thin fertilizer frequently, but also need suitable fertilizer. In addition to daily topdressing, you can add the right amount of rotten cake fertilizer or animal manure under the pot soil when the pot planting on the balcony is just transplanting. When pepper seedlings grow, you can usually apply fertilizer once every half a month, and organic fertilizer is the best. The soil around the root of pepper is loose and put in fertilizer. The fertilizer must be fermented and rotten organic fertilizer, and you generally don't use chemical fertilizer. The specific fertilization techniques are as follows:

First, fertilization characteristics

Pepper needs a large amount of fertilizer and has strong fertilizer tolerance. It belongs to high-nitrogen, medium-phosphorus and high-potassium vegetables. Pepper mainly collects tender fruits, and attention should be paid to the use of potash fertilizer, which is very important to improve fruit quality. In addition, we should also pay attention to the application of trace elements, especially calcium fertilizer, once lack, the fruit is prone to navel rot.

1. Pepper likes nitrate nitrogen fertilizer: the ratio of nitrate nitrogen fertilizer to ammonium nitrogen fertilizer is 1:1.

2. Pepper likes potassium: the absorption ratio of nitrogen and potassium in hot pepper is more than 1 / 1 / 2, and the requirement of phosphorus is not high.

3. Pepper needs a large amount of calcium and magnesium: calcium is an important element in the composition of plant cell wall, which can promote cell wall development and fruit thickening; during fruit development, insufficient calcium supply is prone to navel rot, and appropriate application of calcium fertilizer can improve the disease resistance of pepper. Magnesium is an important component of chlorophyll, magnesium deficiency will lead to yellowing of pepper leaf veins; pepper needs less magnesium at the initial stage of planting, and more magnesium is needed in the harvest period.

4. Pepper is sensitive to boron deficiency: boron participates in the transport and metabolism of carbohydrates, can stimulate pollen germination and pollen tube elongation, and plays a special role in promoting the process of fertilization; when pepper is boron deficient, the root becomes black and rotten, the florescence is delayed, and the flower is unfruitful, affecting the yield.

II. Fertilization methods

Boron is involved in the transport and metabolism of carbohydrates in pepper, can stimulate pollen germination and pollen tube elongation, and plays a special role in promoting the process of fertilization; when pepper is boron deficient, the root becomes black and rotten, the florescence is delayed, and the flower is unfruitful, which affects the yield.

Due to the characteristics of growth and fertilizer demand of pepper, the cultivation method is similar to that of tomato, so the fertilization techniques are more or less the same.

1. Base fertilizer: fertilizer in seedling basin, mainly to prepare seedling soil, the substrate must be fertile soil, and sufficient fertilizer must be applied at the same time, otherwise it will affect the development, and 1-2 times of topdressing should be applied at seedling stage depending on growth.

2. Topdressing: pepper is also constantly hanging fruit, constantly harvesting, constantly carrying away nutrients, so we need to constantly replenish nutrition, on the basis of adequate base fertilizer, we should also topdressing many times. When the fruit begins to expand, the fruit-promoting fertilizer should be applied after topdressing for 3 times (after each fruit harvest). After entering the full fruit stage, the fertilizer absorption capacity of the root system decreases. Spraying once a week for three times is beneficial to delay senescence, prolong harvest time and improve fruit quality.

According to the rules of pepper fertilizer requirement and the concavity and convexity of soil fertility, the trick of potted pepper fertilizer is to re-apply base fertilizer and skillfully apply topdressing, and the following criteria should be followed in detail.

1. Heavy application of organic fertilizer

Apply more mature organic fertilizer (such as chicken manure), and can add a small amount of enzyme bacteria fertilizer bio-organic fertilizer. In the basin of dead plant disease, a little more Bacillus bio-organic fertilizer should be applied. Of course, chemical fertilizer should be selected reasonably, and when chemical fertilizer is used as base fertilizer, simple fertilizer such as urea, calcium superphosphate and potassium sulfate should be selected as far as possible.

2. Skillfully applying topdressing

When topdressing compound fertilizer, we should choose compound fertilizer containing nitrate nitrogen as far as possible, and apply real root in the period of seedling cultivation, transplanting and planting, which can shorten the resistance ability of wheat seedlings to adverse environment. Pepper has the advantages of continuous fruit-setting ability, less falling flowers, high output value and improving quality, so the share of base fertilizer and topdressing fertilizer should be allocated reasonably. In general, organic fertilizer, micro fertilizer, 80% phosphate fertilizer, 50% potassium fertilizer and 30% nitrogen fertilizer are mixed and used as base fertilizer, and the other 70% nitrogen fertilizer, 20% phosphate fertilizer and 50% potassium fertilizer are used as topdressing. Some trace elements such as borax can be foliar sprayed.
