How to grow a good pepper? Pepper planting management points
Pepper has always been one of the essential ingredients on the table, and in Hunan, Guizhou, Sichuan, Hainan and other areas, pepper is deeply loved by local people. The following small series will take you to learn the key points of pepper management in early spring.
First, the type selection
Nowadays, there are many Ledu peppers and hot peppers that are used in production.
Second, the field preparation before planting
Upper fertilizer
Apply composted compost as base fertilizer, apply 5000 kg per acre, 30-40 kg of superphosphate. Mix 1-3 kg of magnesium sulfate or 20 kg of potassium sulfate in the base fertilizer. Before the spring land preparation, all the paving and ditching will be applied 2/3, and another 1/3 ditch. The mulch film cover should reduce the amount of nitrogen fertilizer by 20% than the unmasked one, and properly apply phosphorus and potassium fertilizer.
2. Site preparation
When you are preparing the land, you should turn it with you, so that the soil is loose and fine, and the surface is flat without pits. When laying the film, tighten the film, do not have any space between the film and the surface, and compact both ends with soil. If the mulch film is damaged, it can be sealed with soil. In order to avoid loosening or wrinkling of the film, sulfur can be used to suppress the kneading before the film is laid. Assuming that there are many weeds, it is optional to use a herbicide or spray the herbicide before filming.
Third, colonization
There are two ways to cover up the mulch film. One is to plant the membrane first, and the other is to plant the membrane after planting. After planting, the film is placed on the ground after planting water, and the wheat seedlings are placed according to the plant spacing. The planting holes are cut into cross-shaped holes in the corresponding direction of the film, and the seedlings are passed through the holes, and then the film is laid flat. On the small stilts, the soil is compacted nearby. This method is quick to colonize, but it is easy to hurt the leaves of the wheat seedlings, and the kneading surface is not flat. After planting the membrane first, the planting hole is excavated according to the row spacing of the plant, the soil in the hole is dug out, the seedling is planted, and the membrane near the hole is pressed with the soil.
On the basis of the cover of the mulch film, it is improved to clear the cover on the ground, that is, the mulch is supported at a certain height to form a small arch shed of 30 cm. Comparable mulch masks are planted 5-10 days earlier. When planting, it can also be made into a sorghum 20 cm high and 70 cm wide (30 cm wide). Two deep trenches are opened on the raft, and the seedlings are planted after applying the base fertilizer, and then the small arch frame is covered.
Fourth, the treatment after planting
Water treatment
Covering the mulch can reduce water transpiration. Therefore, the amount of irrigation should be reduced in the early stage of pepper growth to avoid excessive watering and lower ground temperature. In the middle and late stages of plant growth, because the mulch covers the ground temperature and grows and grows, the leaf area is added, and the water transpiration is more. Therefore, the amount of irrigation and the number of watering should be increased to avoid the early decay of the pepper due to drought. The pepper should be sprinkled with water. Irrigate the torrents and flood irrigation.
2. Fertilizer treatment
The bottom fertilizer can not satisfy the demand of all the peppers in the childbirth period. In the middle stage, it should be carried out 2-3 times of topdressing, contact with the ditch furrow, and apply fertilizer and human waste. In addition, foliar spray fertilizer can be used with potassium dihydrogen phosphate and urea. Assuming that the plant is de-fertilized severely, the membrane can be uncovered or scratched in the middle and late stages, and the rhizosphere irrigation and topdressing can be carried out. At this moment, the plant has been sealed and the root growth will not be affected.
3. Interplanting and weeding
After the mulch is covered, the soil temperature can reach 40-50 °C, and most weeds are inhibited from growing, so the sorghum can reduce cultivating and weeding. In the early stage of planting, carry out 2-3 times of cultivating on the ditch, pay attention to protect the mulch of the mulch, and close the planting hole closely to avoid ventilation.
