Pepper is a vegetable that people often eat, and it is also the vegetable variety that most people grow. If you want high yield during the planting process, the pepper pruning process must be less. The following small series talk about the cultivation of pepper pruning in the northern region. technology.
1 Current status of northern pepper cultivation
Due to the cold weather in the autumn and winter seasons in the northern region, it is difficult to grow peppers in the general greenhouses in the late autumn. If the spring peppers are pruned and rejuvenated after normal harvesting, the second development of the plants can be promoted. As a result, the second pepper harvest can be achieved after the autumn extension, and the ability of the pepper seedlings to resist cold and pests after the pruning and rejuvenation is ideal, which not only improves the land utilization rate, but also increases the yield and production efficiency of the pepper. .
2 Chili pruning and rejuvenation
In the production of peppers in the north, in order to realize the second harvest of spring peppers after the autumn extension, it is necessary to master and implement the relevant techniques for pruning and rejuvenating fruit branches.
2.1 Choose high quality pepper varieties
Nowadays, agricultural technology is more and more developed, and there are more and more varieties of peppers, but the adaptability is not the same. However, as far as the northern region is concerned, if it is necessary to achieve the goal of regenerative fruit harvest after the autumn extension, it is necessary to select the dominant varieties with long growing period, low temperature tolerance and disease resistance. For example, the Zhongjiao series is very suitable for the pruning and rejuvenation technology in the northern region. . After selecting the pepper variety, soak the seeds with water and then soak them with copper sulfate solution. Generally, soak for 5 minutes. It is best to use small paper cups or other containers for seedlings. When the pepper seedlings grow to 8 leaves, transplant them. After completion, cover the small greenhouse.
2.2 Maintaining the growth environment of the greenhouse
The cultivation of peppers is generally carried out in a small arched greenhouse, which is advantageous for maintaining its temperature and humidity, and it is easier to ensure the growth environment of the pepper seedlings. The suitable growth temperature of pepper is 23-28 °C.
2.3 Scientific pruning and rejuvenation
In the use of cultivation techniques of pepper pruning and rejuvenating fruit branches in autumn, the pruning and rejuvenation technology is very important, and only scientific pruning can achieve the desired goal. In the northern region, pruning usually begins in mid-September after the first batch of peppers is harvested. When pruning, the small fruit branches in the lower position of the door pepper do not leave the leaf nodes, leaving 3 cm branches, and the tops of the pepper trees leave 2 fruit nodes for the branches. After the first pruning, the second pruning is carried out for about 20 days, and each pepper tree is cut to leave 3 or 4 strong branches. It is best to carry out the pruning by professional technicians, and after completion, review and check to ensure the quality of pruning.
2.4 Safeguarding water and fertilizer supply and preventing pests and diseases
The dealer has a flower, and he relies on fat to be the master. The rejuvenation technology of the pruning and rejuvenation of peppers is also inseparable from sufficient fertilizer and moisture. In terms of water and fertilizer supply, since this technology significantly prolongs the growth period and the number of fruiting times of pepper plants, it is necessary to use sufficient fertilizer amount in the early stage preparation and fertilizer application. High-quality pepper base fertilizer can be used with diammonium phosphate, superphosphate and farm organic fertilizer. When applying the bottom fertilizer, try to deepen and mix well. In the later stage of growth, fertilization is appropriate to ensure the normal growth of the plant, neither too little nor too much. In terms of water supply, the humidity in the shed should be ensured during the seedling period. After the planting, a small amount of watering should be carried out to ensure the soil is moist, and it is adjusted according to the weather conditions.
At the same time, the prevention and control of pepper pests and diseases is also very important. Common pests in pepper fields in northern areas include aphids, tobacco budworms, etc., which can be controlled by anti-carboside, avermectin or kungfu 3 000 times liquid; the diseases are mainly gray mold, smashing disease, etc. Killing, bacteriostatic and other agents control. In addition, ecological control methods should be adopted to reduce the frequency and quantity of chemical agents and ensure the safety of fruits. For example, in September, the aphids and ladybugs occur in the pepper fields. An insect net should be installed at the opening of the greenhouse or a trap should be installed at a distance to prevent the pests from entering the greenhouse. All in all, the prevention and treatment of pests and diseases is very important in the use of regenerative technology after the replanting of the northern peppers in the autumn. The prevention and treatment technology is the main prevention and prevention combination to ensure the growth of the whole process of pepper is not infringed.
Pepper pruning can make peppers regenerate fruit branches, which can promote the increase of pepper yield, and can also extend the pepper fruiting period. The above is a detailed cultivation method, you can refer to it.
