High-yield Cultivation Techniques of Plastic Film Capsicum

Pepper covered with plastic film is generally sown and raised seedlings in late December and planted in the middle and late April of the following year; until late October, the growth period is up to 10 months, and the average yield per mu is about 4000kg, which can be interplanted with wheat or planted in winter fallow. The average output value per mu is generally about 2500 yuan, and the main points of cultivation techniques are as follows:

Cultivate strong seedlings

The varieties of pepper covered with plastic film are mainly Bianjiao series, and the sowing time is from mid-late December to early January. The seeds were treated before sowing, and then the sterilized seeds were soaked in warm water for about 30 ℃ for 8-12 hours. after absorbing enough water, the seeds were wrapped in a clean wet cloth and germinated under the condition of 28-30 ℃. When most of the seeds are white, they can be sown. Pepper seedlings covered with plastic film are usually raised in a greenhouse or a hot Kang. After sowing, the temperature of the seedling bed is kept at 25 ℃ during the day and 18 ℃ at night. When the seedlings are all grown, the temperature drops to 25 ℃ in the daytime and 15 ℃ at night. 7 days before seedling separation, the film was gradually released and ventilated, and the seedlings were refined at low temperature.

Timely seedling division

Plastic film pepper seedlings should be divided, usually in the first and middle of March, when the seedlings are 3 leaves and 1 heart. Water properly on the seeding bed the day before the seedling is divided, so as to reduce the root damage when the seedling is raised. The distance between seedlings should be 8-10cm, with two plants in each hole, and large and small seedlings should be separated at the same time. After planting, a small arch shed should be added in time, and grass should be covered if the temperature is low at night. There is generally no air in 3-5 days after seedling separation, open the grass during the day and cover it at night to increase the temperature of the seedling bed as much as possible and promote root growth. to slow down the seedlings. 5-7 days later, the new leaves grow, and the slow seedlings end, and the ventilation can be gradually increased with the weather. 7-10 days before planting, that is, about April 10, it can be ventilated day and night for seedling exercise. In order to control the excessive growth of seedlings, except that the seedlings are watered at the time of seedling division, they are usually not watered any more. until the seedling is watered once before transplanting.

Soil preparation and fertilization

To avoid continuous cropping of chili peppers, the best plots for planting plastic film chili peppers are eggplant fruits and vegetables within 2-3 years, onions and garlic are the best, followed by legumes, cabbage and so on. Before soil preparation, more than 5 square meters of mature organic fertilizer were applied per mu, calcium superphosphate 50kg and potassium sulfate 20kg were used as base fertilizer. After ploughing, a small high ridge with a width of 60cm was set up every 40cm, and the temperature was raised by plastic film mulching about 7 days before planting.

Timely planting

Plastic film pepper is generally planted in mid-late April (around Grain Rain). When planting, first dig holes in small high ridges according to row spacing 40cm, plant spacing 33cm, triangular seedling method is the most suitable, 4000 holes per mu, 8000 plants. If the condition of water and fertilizer is poor, the planting density can be increased appropriately.

Field management

On the basis of watering the planting water at the time of planting, slowly watering the seedlings in time, until the door pepper sits down, generally no more watering, when the door pepper grows to the 3cm or so, the combination of watering, re-topdressing, urea 15-20kg per mu, potash fertilizer l0kg, and then every 2 Mel 4 water to top up the fertilizer. Watering should be done frequently with small water, avoid flooding, and Rain Water should be drained in time when he is too big. Under normal circumstances, door pepper should be harvested in time to avoid "falling seedlings".
