High-benefit cultivation techniques of Wild Pepper

Wild mountain pepper, commonly known as Tianjiao, is mainly used as seasoning for cooking and side dishes, and spicy non-staple food. Wild mountain peppers can be eaten both fresh and dry, and can also be processed into canned food. canned green peppers in recent years have become popular in the market and are in short supply. Planting wild mountain pepper has the advantages of low investment, high yield and wide sales, with a yield of 150m / mu and 2000kg / mu.

Seedling site selection

Choose the plots with shelter from the wind and the sun, high terrain, convenient drainage and irrigation, close to the field and high soil fertility, and the selected seedling bed should not have planted eggplant fruits, melons, vegetables, tobacco and other crops, in order to prevent the spread of diseases.

Seed treatment

1. Put the seeds in a clean container, soak the seeds in an appropriate amount of water for 20 minutes, then soak the seeds in 55 ℃ hot water for 15 minutes, pick up and scrub the seeds with clean water; 2, soak the seeds in clean water at room temperature for 8 hours to fully absorb water; 3. Soak the seeds in 10% trisodium phosphate solution for 20 minutes, then rinse clean with clean water. This method can control bacterial wilt and virus.

Sowing sparsely and evenly sowing strong seedlings

As the saying goes, "the seedlings are 30% better". In order to promote the seedling growth, early budding, early harvest, prolong the harvest time and increase the yield, we can appropriately advance the sowing date. Generally, sowing begins in late January, and the selected nursery land is deeply ploughed and turned into a bed. Each mu of field needs about 8 mi 10 square meters of seedbed. 100 kg of mature house fence fertilizer is evenly spread on the border surface and raked evenly with the soil. The furrow is 1.5 meters wide and covers a ditch with a width of 2530 cm and a depth of 30 cm. Water the soil before sowing, keep the soil moist, sow seeds evenly and sparsely, sow seeds evenly and sparsely, cover 1.5ml 2cm with fine soil or civil ash after sowing, and then use nylon film arch shed to raise seedlings. After the seedlings are unearthed, the seedlings should be refined as soon as possible to make the seedlings strong and improve the stress resistance. In addition, the seedling stage should also pay attention to the field humidity, there can be no waterlogging in the field, when it is sunny for a long time, it should be properly watered to keep the seedling land moist. When the seedlings grow to 2 true leaves, weeding and light tillage are carried out to make the soil breathable to ensure that the roots of the seedlings are developed.

Reasonable close planting

Wild pepper seedlings can be transplanted when they grow to 4 leaves and 1 heart. The fields planted with wild mountain pepper were ploughed and furrowed with a width of 1.3 meters, a ditch width of 0.3 meters, a depth of 20 meters and a plant distance of 0.8 mi 1.0 meters. Wild mountain pepper harvest time is longer, generally can be harvested to the first frost period, the crown is large, up to 1MUR 1.2 meters. Therefore, the use of single-row hole planting, 600 Mu of 650 plants per mu. When transplanting, 25 kg of phosphate fertilizer and 300 kg of rotten manure per mu were mixed and applied as base fertilizer according to the hole, and mixed well with the cave soil, the seedlings were transplanted with soil, and the root water was irrigated in time after transplanting.

Fertilizer and water management

Wild pepper is not strict on the soil, can grow normally in clay and sandy loam, both drought and barren tolerance, avoid waterlogging, but there should be appropriate water and sufficient nutrients to ensure high yield and high quality. After 7 days of transplanting, the rotten dilute manure water was applied once every 7 days, with a small amount of compound fertilizer added each time, and 2 Mel was applied continuously for 3 times. At the beginning of budding, combined with ploughing and weeding, fertilizing and cultivating soil, 1000 kilograms of rotten manure and 50 kilograms of compound fertilizer were applied per mu, and 0.25 meters of 0.3 meters of fertilizer was applied between plants. the soil should be covered after application, and the soil should not be loosened after flowering to prevent the root from being infected with bacterial wilt. After each harvest, quick-acting fertilizer should be applied properly, and at the same time, attention should be paid to deepening borders and ditches, properly cultivating soil, eliminating stagnant water, watering during drought and keeping the soil moist in order to maintain good growth.

Pest control

1. Prevention and control of bacterial wilt. Before transplanting, 100ml / mu of lime or plant ash was applied to soil preparation to regulate soil pH and inhibit the reproduction of bacteria. At the beginning of the disease, the use of 14% ammonia copper solution 300x, 77% can kill 500x wettable powder or 4000 times agricultural streptomycin sulfate, once every 10 days, for 4 times in a row. Diseased plants should be removed in time and disinfected with lime to prevent infection.

2. Prevention and treatment of anthrax. Spray with 50% mancozeb 800 times, 1000 Mel 1500 times or Aimao 3000 Mel 4000 times, once every 7 days, 2 Mel for 3 times.

3. Pay attention to the prevention and control of aphids to prevent the spread of virus diseases. It is better to control aphids with the solution of 3000ml 4000 times or Aktai 4000kg / mu mixed with 50ml / mu of water.

Timely harvest

Wild mountain pepper is a kind of vegetable which blossoms and bears many times, and mainly collects green fruit, so picking in time is beneficial to increase yield. The standard of picking green pepper is that the fruit is full and full, the color of the pericarp becomes dark, and it can be picked when it is bright and clean. Generally choose to pick in the morning or evening, picking with a handle, do not turn left and right or lift up, so as not to move the plant.
