Planting method of linear pepper

1, line pepper seed treatment: seedling is generally from vernal equinox to Qingming. Expose seeds in the sun for 2 days to promote after-ripening, improve germination rate and kill germs carried on the surface of seeds.

Or use 0.5% trisodium phosphate or 300-400 times potassium permanganate. Or 1% thiourea for 20-30 minutes to kill the germs carried on the seeds. After washing the seeds repeatedly, soak them in warm water of 25-30 degrees for 8- 12 hours.

2. Line pepper seed sowing: After the seedbed is completed, water should be poured on the soles of the feet, and then pesticides and fungicides should be sprayed for disinfection. Then sprinkle a thin layer of fine soil, evenly spread the seeds on the seedbed, cover it with a layer of fine soil with a thickness of 0.5- 1 cm, and finally cover it with a shed for moisturizing and heating.

3. Line pepper planting process: timely planting to promote early rooting. Early seedling development is the main principle to master the planting period and post-planting management. Line pepper should be planted in ditch or flat land. When planting, it should be covered with shallow soil, and then gradually ridged and closed. After planting, squatting seedlings only by drought will damage the root system, so the seedling management of line pepper should be small or unnecessary, so as to promote it to the end.

4, line pepper intertillage weeding: after planting survival, shallow intertillage once in time. Plants began to grow and concentrated in intertillage once. Before the factory closes, cultivate again. Intertillage combined with weeding and ridging.

5. Fertilizer and water management of line pepper planting: after planting, it is necessary to grab the top dressing fertilizer on sunny days, and the dosage should not be too much and too thick each time, otherwise it will easily lead to excessive growth and delay flowering and fruiting. When the first and second layers bear fruit, more fertilizer should be applied to promote fruit growth.

After fruit picking, it is more necessary for the soil to have enough fertilizer and water for plants to grow and bear fruit normally. If it rains heavily before the soil is dry after watering, the phenomenon of falling leaves and dying will be quite common, especially during the period from ups and downs to beginning of autumn.

Therefore, when irrigating, we must decide the irrigation time according to the weather forecast. The depth of irrigation shall not exceed three-quarters of the side ditch, and it shall be carried out at night or in the early morning, and emergency irrigation and drainage shall be carried out.

6. Picking of line pepper: As fresh food, most green fruits can be harvested, and red fruits can also be harvested. As the main pepper, it is necessary to harvest the red ripe fruit in time, otherwise it will affect the growth and fruit of the plant.

Extended data

Matters needing attention in planting line pepper:

First, preparation before broadcasting

1, soil preparation

It is best to choose loam or sandy loam with medium soil fertility and deep soil layer, and continuous cropping is strictly prohibited. Apply 2000 ~ 3000 kilograms of farm manure and 30 kilograms of three-feed phosphate fertilizer to 667 square meters, evenly spread on the surface before autumn ploughing, and turn it into the soil in combination with autumn ploughing.

2. Soil treatment

In order to control gramineous weeds, chemical weeding can be used before sowing hot pepper.

3. Seed treatment

Soak the seeds in warm soup for disinfection, that is, soak the seeds in cold and hot water (water temperature 55 ~ 65℃) for 30 minutes while stirring. Chemical treatment: Soak the seeds with 1% trisodium phosphate for 30 minutes, and soak the seeds with 0/00 times of formalin solution for 20 ~ 30 minutes.

Second, sowing date and sowing method

Line pepper is an early sowing crop, which is usually sown before April 1 ~ 10. The sowing depth is 2 ~ 3 cm, and the sowing amount is 0.8 kg per 667 square meters. Auxiliary materials (slag, sawdust, phosphate fertilizer particles, etc.) must be supplemented. ); The sowing method is direct seeding, generally using three small films and twelve rows, sowing on the film, covering soil 1 ~ 2 cm, and breaking the board in time after rain.

There are about 1.5 million seedlings per 667 square meters, each hole 1 plant, 2 plants can be left in the absence of nest, and the number of harvested plants is 1. 1 ~ 1.2 million plants /667 square meters.

Third, on-site management

1, releasing seedlings, thinning seedlings and fixing seedlings.

When more than 60% seedlings emerge under the film, seedlings can be released, and the hardening should be broken when it rains. The emergence of linear pepper is concentrated, so it should be interplanted in time to facilitate individual development. When the height of hot pepper is as high as 9 ~ 12 cm, seedlings can be fixed, and the spacing between plants is 9 ~ 12 cm.

2. Irrigation

The root system of pepper is underdeveloped and shallow, so it is not suitable for watering for too long. Flood irrigation is prohibited, and furrow irrigation or drip irrigation must be adopted. Irrigation amount: irrigate 5-6 times in the whole growth period, and the irrigation amount per water is 50-60 cubic meters /667 square meters to keep the soil moist. Based on the principle of small water irrigation, it is forbidden to flood with water and accumulate water in the field, and it is also the main measure to prevent and control pepper blight without watering in hot noon and rainy days.

Step 3 apply fertilizer

Farmhouse manure is the best. At present, cotton stubble land is especially suitable for pepper growth because of its abundant fertilizer for many years, but it is not suitable for excessive fertilization. Generally, 60 ~ 100 standard fertilizer can be applied to 667 square meters, and drip irrigation with drip irrigation fertilizer can reduce the dosage.

Third, pest control.

The local pests are mainly moth-eating pests such as cotton bollworm, cutworm and corn borer, which should be prevented as soon as possible.

The main disease is pepper blight, which can be prevented by spraying fungicides. The interval of application is 10 ~ 15 days, which can effectively reduce the harm twice in a row. It can be prevented by no continuous cropping and no flooding.

Fourthly, harvesting and drying.

When 70% of peppers naturally mature and lose water and turn purple, they should be picked and dried in time. When picking, the line peppers with pests and diseases should be picked separately to avoid affecting the quality. When it is dry, it should not be spread too thick or too thin. The dried line peppers should be piled up in a centralized way, and the tarpaulin should be tightly covered to prevent the dry peppers with white skin from appearing in the wind, wind and sun.
