How to manage pepper after waterlogging

The rainstorm occurred in our province in July, most of the farmland had stagnant water, and the production of hot pepper was also affected to a certain extent. At present, the focus of field management should be to protect roots, promote seedlings, and prevent falling flowers, fruits, leaves, diseases and insect pests.

1. Drainage and waterlogging reduction

Pepper is a drought-tolerant and water-repellent crop. Flooding during fruit expansion, especially flood irrigation, is the main cause of the death of pepper in a large area. It is strictly forbidden to flood the ridge back, if there is a stagnant water phenomenon, immediately drainage, so that with the rain along with drainage.

Second, high ridge topdressing

Before sealing the ridge of hot pepper, we should cultivate the soil to protect the root and pick the high ridge in time, which can not only prevent the plant from lodging, but also help to drain and prevent waterlogging in rainy days. When cultivating soil, combined with topdressing, 20 kg of N, P, K ternary compound fertilizer was applied per mu. Dried peppers should be removed in time to grow into the door pepper, to pepper, to prevent falling seedlings, fresh peppers should be timely harvest of commercial fruits to increase production.

Third, dry along the ridge

Due to continuous overcast and rainy weather, for the land seriously eroded by Rain Water for a long time, when the weather improves and lasts sunny for more than 3 days, the soil at the base of pepper stem can be planed along the ridge, deep 10cm, drying for 1 day, which can effectively improve soil permeability, promote root development, and re-cultivate on the second day, at the same time, use 1 gram of "92 ○" per mu, spray 50 kg of water, and promote the growth of new leaves.

IV. Prevention and control of diseases and insect pests

In case of continuous overcast and rainy weather, the root system of pepper is easy to rot and induce some diseases, such as leaf mold, blight and so on. The main diseases of sharp pepper are virus disease, anthracnose, scab, blight and bacterial wilt. You can use 20% virus A700 times, 70% methyl thiophanate 1500 times or 80% anthrax Fumei 1000 times, 60%DTM1500 times or 77% can kill 1000 times, 58% metalaxyl manganese zinc 400 times or 72.2% Pulike 1500 times, 14% complexamine copper 1000 times or 72% agricultural streptomycin 3000 times. The main pests of sharp pepper are cotton bollworm, tobacco green worm, aphid and red spider. The main reason for the decrease in yield is that pepper is rotted and shedding in large quantities caused by worm-eaten pepper. In production, the period when the pest larvae have not yet entered the pepper fruit is the best period for pest control. In this period, it is necessary to timely spray effective and low-toxic pesticides with good efficacy to kill cotton bollworm and tobacco green worm, such as Yitaibao, Dupang Anda, BT and so on. Aphids and red spiders can be sprayed with imidacloprid, rapid killing of mites or trimethoprim, respectively. Zhang Cuiyun
