1 Variety selection Select disease-resistant and high-product varieties, such as: Holland Rexwang 37-74 Extra Large Beef Jiaojiao Variety, Zhongnong Shengjiao, Jincaijiao F1, Hongxing No.2, Huangmeiren, etc. , Fruit type, high yield.
2 Sowing seedlings
2.1 The sowing amount and sowing date are generally 1850-2280g/hm2. Greenhouses are sown in mid-to late December, and nursery seasons are 80 to 90 days. The nursery period can be extended until buds are larger but not flowering.
2.2 soaking seed germination first soaked with water 2h, after soaking in 55 °C warm water soaking 15min, when the water temperature dropped to 30 °C, remove the bad seed pod seeds, and then wash with water 3 to 4 times, remove the seed coat mucus, go Spicy rice, mixed with fine sand germination, initial germination temperature of 25-30%, when a small number of seeds hair buds, and then germination temperature to 20 ~ 25 °C buds, 5-6d complete germination.
2.3 greenhouse seedlings nursery will be decomposed farmyard manure and soil by 1:5 ratio of mixing, decoration, with "green seedlings" dilution penetrating nutrient soil, then sowing seedlings, cover film, set up a small shed, after the emergence of the film, First, remove the arch shed during the day. After 5 days, remove the arch shed in the evening. Do not water the soil and pay attention to disease prevention and pest control.
3 Colonization
3.1 Before planting, prepare 80-115t/hm2 farmyard manure, mix 750kg/hm2 of superphosphate, and pour 2/3 plow into the soil to make the base fertilizer, and do it according to the ridge width 0.5-0.6m (or width 1m) and height 15cm. The high bed, then ditch the remaining 1/3 of the fertilizer, plus 450kg/hm2 of diammonium phosphate, 300kg/hm2 of potassium sulfate, and 1450kg/hm2 of cake fat. One week prior to planting, it was sterilized with a sulfur smoked shed. 100m2 of sulfur powder 150g, sawdust 0.5kg, and trichlorfon 0.5kg were placed in several places in the shed to light the smoked shed to exterminate insects. 7 to 10 days before planting, the air release during the day, so that the temperature dropped to 15-20 °C, 12 °C at night, enhance ventilation, low temperature hardening seedlings.
3.2 Planting time and method Greenhouse peppers are usually planted from mid-February to early March, with single or double planting per hole, plant spacing of 30 to 33 cm, colonization of 50,000 to 60,000 plants/hm2, and appropriate application of dihydrogen phosphate when planting. Potassium and other foliar fertilizers will be scientifically managed according to plant growth after easing seedlings.
4 Field Management
4.1 Temperature During the low temperature period, the temperature conditions required for normal growth should be maintained as much as possible, keeping 25-30% during the day, 17-20% at night, 20°C left at the ground temperature, and 15°C above the minimum. During periods of high temperature, when the outside air temperature is higher than 15%, the air is released day and night, so as to avoid longevity.
4.2 When the pepper seedlings grow 3cm long, combine the first fertilizer with watering, topdressing urea 150kg/hm2 or potassium sulfate 120 ~ 150kg/hm2, then grow fertilizer by 15 ~ 30d 1 times, generally 3 times water, chase A fertilizer, so that the little water pouring, do not flood irrigation, both to ensure crop water supply, but also prevent the greenhouse humidity caused by excessive disease.
4.3 After the results of the pruning pepper, the weak branches are removed to facilitate ventilation. When the fruit grows to 1cm, the leaves can be picked up from 4 to 6 leaves according to growing trend. Extirpative shoots are removed at the middle and later stages to concentrate nutrients and fruit growth. Morning city.
5 Pest control
5.1 Epidemic diseases are common diseases of peppers. Once they occur, serious reductions in production occur. Prevention and control should be focused on prevention and control, and the level of cultivation and management should be improved. Anti-virus drugs can be used for prevention and control in combination with agricultural streptomycin or metalaxyl.
5.2 Virus Disease Virus disease is mainly caused by aphids and whitefly, and how to fertilize sweet pepper before and after the results are mostly tobacco mosaic virus. Dichlorvos and once-in-a-net can be used to prevent and control the transmission source. At night, Uranus plus dichlorvos and other smokes are used. The method of fumigation of the agent strengthens the prevention and treatment, and the individual plants infected at the initial stage of the virus disease may adopt the method of first removing and then applying the drug. In the first week of infection, the drug was sprayed once every 3 days, and was sprayed 22 times. After the disease was controlled, the drug was administered once a week for about 3 consecutive times. The drug was used alternately; and in combination with the virus disease prevention and control leaflets, the insecticide was used simultaneously. Plants with the enemy's spirit, plant diseases, and other diseases sprayed plants once a week to promote leaf growth.
5.3 Other pests and diseases Pepper anthracnose can be controlled with mancozeb and other agents; Botrytis cinerea can be controlled by drugs such as gray mold g and L. sativae can be controlled by insect pests.
6 After proper harvesting and planting for 50 days, harvesting will begin in mid-to-late April. Peppers and peppers should be harvested as soon as possible.
The Digital Video Recorder is far superior to the analog monitoring equipment in terms of the image processing, image storage, retrieval, backup, network transmission, and remote control because of the adoption of the digital recording technology.
By the way, there are many BNC video interfaces on the back of the Digital Video Recorder, each interface can be connected to an analog suveillance camera. Just plug the interface, then it works, very convenient!
Generally speaking, the Digital Video Recorder can be divided into the hard disk video recorder, the PC type hard disk video recorder and the embedded hard disk video recorder, etc. Among them, the embedded hard disk video recorder does well in the stablity, the reliability, and the easy use, and the embedded hard disk video recorder will gradually invade the market of the PC type hard disk video recorder.
Besides, The main functions of the Digital Video Recorder include: monitoring function, recording function, playback function, alarm function, control function, network function, password authorization function and work schedule function.
Monitoring function: The monitoring function is one of the most important functions of the Digital Video Recorder. Whether it can monitor the on-site camera video clearly is a core issue of the surveillance system. Most Digital Video Recorders can achieve clear on-site surveillance.
Alarm function: The alarm function mainly includes the input alarm of the detector and the alarm of the image and video detection. Once received the alarm signal, the system will automatically start recording, and turn on the corresponding spotlight, siren and network output signal via the alarm output function. The image motion detection is the main alarm function of the Digital Video Recorder.
Control function: The control function refers to the omnidirectional control of the PTZ and lens via the host, which is generally finished by the dedicated decoder and the keyboard.
Network function: The user can do various operations to the host such as the monitoring, recording and control after the simple identification on the LAN or WAN, which is similar to the local opertaion.
