First, field management
Peppery rainy season management technology
1, drought resistance
Pepper plants are most afraid of waterlogging, and they have to grasp the timing when watering the heads. When noon light shines, the leaves are not heavy and wilting indicates no drought, and generally do not need watering. Even severe wilting depends on the weather, listening to weather forecasts (water can not be watered before the rain), pouring small water to prevent waterlogging caused by falling water after watering.
2, cultivator, plan
The ploughing and hoeing can promote the development of the root system. In particular, after the watering, the land must be ploughed in time. The cultivator must flatten the ground after the cultivator to prevent wind loss, loosen the soil, promote growth, and reduce disease.
3, Baohua, Baoguo
Flowering period should be sprayed to get the enemy stable + Rui Peile + Ruipei boron, control Wang, Zhuangzhuang, Baohua, Baoguo.
4, timely fertilizer
In 50% pepper tree just sit pepper, topdressing nitrogen and potassium fertilizer once, do not only chase urea, in order to avoid prosperous and increase young tissue and pests and diseases.
5, remove weeds
Weedicides must be sprayed on weeds in Jiaotian to prevent overcrowding of weeds and pepper seedlings, win light, compete for fertilizers, and remove or destroy suitable habitats for pests.
Second, disease prevention
Most of the diseases of pepper are spread by wind and rain, so they must be sprayed and prevented before entering the rainy season. They should be sprayed once every 7 to 10 days. Before the rain, protective agents are sprayed. After the rain, systemic agents are sprayed and the diseased spray is found to be a therapeutic fungicide.
Third, cause
Falling disease (fallen leaves, falling flowers, falling fruit):
It is mainly caused by sores, leaf spot, anthracnose, viral diseases, insect pests, and physiological diseases. Dead tree disease is mainly caused by epidemic disease, verticillium wilt, root rot, and bacterial wilt; rotten fruit disease : Mainly caused by anthrax and sunburn.
Scab, leaf spot, and bacterial wilt
With nitro humic acid copper 750 times + Wei Ruo Fu Mei double 600 times spray or spray control; Anthrax tebuconazole anthrax 1500 times; Phytophthora fluoridum Ferox pass 600 times + Nitro humic acid copper 750 Times, spraying the lower part of the plant or irrigating roots; root rot with rust-Fumei double 600 times + 750 times copper nitrohumuvate, spraying the lower part of the plant; viral disease with 20% do not indole copper acetate, spraying the back of leaves.
