Planting technology of sweet pepper, how to plant sweet pepper

Before planting sweet pepper, apply enough base fertilizer on the selected plot and dig deep into the soil to make the fertilizer and soil fully mixed, so that the plants can better absorb nutrients. If possible, it can be disinfected when methyl bromide is used as soil before planting, and the plot can be made into a small high frame with a width of 80 cm and a height of 15 cm. Break the clods on the border and form a ridge for watering and fertilizing. The north-south direction is suitable for ravines.

When the seedling age is about 40-45 days, the seedling grows to five leaves and one heart, the cotyledons are complete, the leaves are dark green, plump and stretched, the new leaves are fresh and tender, the stems are stout, the internodes are short, the flower buds are well differentiated and the roots are developed. The planting density is 1800 plants/mu. When planting, besides planting the seedlings straight, even and upright, we should also pay attention to the planting depth, which should be equal to the depth of the seedling substrate. In order to prevent seedling wilting and promote seedling delay, please water it immediately after planting.

Seedlings should be watered once after planting, and then watered once every seven days, with nutrient solution every time. If the concentration of nutrient solution is low in the early stage, it will be high in the peak period. In the early stage of planting, light watering, early topdressing and diligent cultivation can promote the seedlings to take root slowly.

Sweet pepper likes warm water, and it is easy to get sick at high temperature. When the water is full, it is easy to die, and the fat head is easy to burn the roots. Therefore, there should be different management requirements in different growth stages of the whole growth period. In high temperature season, too high surface temperature will inhibit the normal growth of sweet pepper roots and directly induce the spread of virus diseases. Therefore, it is necessary to protect the root seedlings, keep the soil moist, and drain water in time after the rain to prevent the root system from weakening. In rainy season, soil nutrients are lost more, so ammonium sulfate can be applied topdressing and attention should be paid to weeding in time.

Pruning is more important in the whole growth period. Removing the old leaves and yellow leaves from the lower part of the plant can transport more nutrients to the fruiting branches and provide ventilation. If pruning is not timely, it will have a great influence on fruit quality, and it is easy to produce deformed fruits and reduce product quality.

Sweet pepper plants can't grow upright. When the plant grows to a certain height, it should be set up and fixed in time to prevent lodging, and the stem of the plant should be tied to the fixing frame. In the process of its growth, we should always pay attention to the binding of stems and leaves, so that it can better accept the sun and grow healthily.

The growth and development of sweet pepper enters the full fruit stage, when seedling emergence and fruiting are carried out at the same time, which is the key period to determine the yield. Therefore, it is necessary to do a good job in promoting seedlings and protecting fruits. Growing fruits have an important influence on the vegetative growth and development of plants. With the increase of the number of fruits, the quality of newly opened flowers declined, and the fruiting rate declined. If the fruit is picked, the quantity will be reduced, the growth time will be shortened, the flower quality will be improved, and the flowering and fruiting will be normal. Therefore, the vegetative growth should be promoted before fruiting, and the fruits should be picked early at the beginning of fruiting to ensure the number of flowers and the fruit setting rate.
