What are the prospects for growing chili peppers in 2020? How to grow chili peppers?

Pepper is one of the most common spices in daily life. In Hunan, Guizhou, Sichuan and other provinces, pepper has even become the main ingredient. So what are the prospects for growing chili peppers in 2020? How do you grow chili peppers?

I. What is the prospect of planting pepper in 2020?

Chili grows faster and has strong adaptability. It is relatively simple to plant and is very suitable for planting. In 2019, the price of pepper on the market has risen to a certain extent. In many places, the supply of pepper is in short supply. It is expected that the price of pepper will not fall rapidly in 2020, so the prospect of planting pepper is also very good.

2. How to grow pepper?

1. shangfei

Apply decomposed compost as base fertilizer, 5000 kg per mu, 30-40 kg calcium superphosphate. 1-3 kg magnesium sulfate or 20 kg potassium sulfate are mixed into the basal fertilizer. Before soil preparation in spring, it shall be fully spread and furrowed, 2/3 of which shall be spread and 1/3 of which shall be furrowed. The amount of nitrogen fertilizer should be reduced by 20% and phosphorus and potassium fertilizer should be increased appropriately if the plastic film is covered than that not covered.

2. soil preparation

When preparing the soil, it should be turned with harrowing, so that the soil is loose and finely divided, and the surface of the ridge is flat without potholes. Tension the mulching film when laying the film. There should be no vacancy between the film and the ridge surface. Both ends should be compacted with soil. If the mulch is damaged, it can be sealed tightly with soil. In order to avoid film relaxation or occurrence of wrinkles, not before the film can be used to suppress sulfur seed ridge surface. Assuming more weeds, you can choose herbicide film or film spraying herbicide.

3. colonization

There are two ways to cover pepper film, one is to spread film first and then plant; the other is to plant first and then spread film. After planting, film spreading is carried out. After planting and watering, wait for the ground to be slightly dry, arrange wheat seedlings according to plant spacing, cut cross-shaped planting holes in the corresponding position of the film, sleeve the seedlings from the holes, spread the film on the small high ridge, and compact the nearby with soil. This method of planting speed, but easy to hurt the leaves of wheat seedlings, and the surface is not flat. The method comprises the following steps of: firstly spreading the film and then planting, digging planting holes according to plant spacing, digging out soil in the holes, planting seedlings, and pressing the film near the holes with soil.

On the basis of mulching, it is improved to make it clear that the mulching film is covered on the ground, that is, the mulching film is erected at a certain height to form a small arch shed with a distribution of 30 cm. 5-10 days earlier than mulching. When planting, it can also be made into a high ridge of 20 cm high and 70 cm wide (ditch width of 30 cm), two deep grooves are opened on the ridge, seedlings are planted after applying base fertilizer, and then small arch frames are inserted for film mulching.

4. watering

Mulch cover can reduce water transpiration, therefore, pepper growth early should reduce irrigation, avoid excessive watering and cause ground temperature to decrease. In the middle and late stage of plant growth, because the plastic film covers the ground temperature and grows actively, the leaf area is increased, and the water transpiration is more, so the irrigation amount and watering frequency should be increased to avoid premature senescence and yield reduction caused by drought. Pepper watering should adhere to small water irrigation and avoid flood irrigation.

5. fertilization

Base fertilizer can not meet the needs of all childrearing pepper, in the middle should be 2-3 times topdressing, contact furrow irrigation, topdressing fertilizer and human excrement. In addition, potassium dihydrogen phosphate and urea can be used for foliar spraying. Assuming severe plant defertilization, can be in the middle or late film or tear film, rhizosphere irrigation topdressing, at this moment the plant has been closed ridge, will not affect root growth.
