The sweet pepper belongs to the Solanaceae vegetable, the cultivation and management technology is simple, and the economic benefit is relatively stable. To grow sweet peppers, we must first cultivate good seedlings. At present, the most common way of raising seedlings is to plant seedlings at the factory, but the investment scale is large and the technical requirements are high. The second is the greenhouse nursery, which is suitable for sharing with multiple households. Otherwise, it is too wasteful. The small shed nursery is an economical, easy-to-grow young seed breeding technique that is more suitable for single-family operations. Now we introduce the greenhouse cultivation techniques of sweet peppers in greenhouses as follows:
?? 1, the choice of fine varieties. General selection of good bell pepper varieties with long shelf life, good resistance to storage and transportation, and suitable for export and supermarket sales. At present, there are many types of sweet peppers suitable for cultivation in the solar greenhouse in China. Among them, the imported varieties include Israeli McCabe, Comanche, Lyon, Mayo, Dutch Safiro, Savita, Red Indah, Red Rodan, and Dutch Colors. Pepper has white princess, Zi Guiren, Huang Obao, Orange and West Asia, etc. Domestically produced Yuyi Agricultural Research Institute No. 21, Zhengjiao No. 7, Qingdao Superstar Sweet Pepper and so on.
?? 2, select the nursery site. The suitable period for planting sweet peppers in greenhouses in Shandong is usually around July 25. Since it is in the rainy season to raise seedlings, the nursery should select land plots with high topography and well-drained water, and at the same time require the soil of the selected land to be loose and easy to water.
??3, construction of seedbed requirements. The root system of sweet pepper seedlings is relatively developed and can be sown directly in the nutrient bowl. The 600m2 solar greenhouse is generally set to about 2000 seedlings, requiring a seedbed of 30 to 40 m2. First, dig a large drainage ditch around the intensive cultivation plots, dig a small drainage ditch at intervals of two seedbeds, remove weeds, and reduce the sources of pests and diseases.
In order to prevent pests such as cockroaches and cockroaches from entering the seedbed, the perimeter of the seedbed shall be gauzed with gauze. The seedbed is 1m wide and 8m to 15m long. The seedbed is deep-sweeped by 20cm. The seedlings are surrounded by 10cm high ridges to prevent rain irrigation. The seedbed is preferably north-south, with uniform illumination and neat seedlings.
?? 4, prepared a good nutrition soil. When the nutritious soil is formulated, generally 6 parts of mature garden soil and 4 parts of decomposed ring fertilizer are used, and the mixture is fully sieved after mixing. If organic chicken manure or bean cake is used as organic fertilizer, it should be mixed in a ratio of 1:9 of organic fertilizer and mature soil, otherwise it is easy to burn seedlings. Use 10cm10cm specifications of plastic nutrient cartridges, can also use homemade paper tube nutrition. Place the nutrient soil at 1cm below the bowl and place it neatly in the seedbed. Do not overfill the soil when it is installed, otherwise it is difficult to water and sow, and the seedlings are also weak.
?? 5, seedlings seedlings processing. Before sowing, Miao Wei used a watering can to pour 2 wells of water. After spraying the second well water, evenly spray 50% phoxim EC 500 times to control underground pests. After the water is completely infiltrated, 1.5 kg of 40% carbendazim wettable powder is added to 75 kg of fine soil, and after thorough stirring, it is uniformly applied to a seedling of 50 m2, which can prevent seedling disease. At the time of sowing, the seeds were sown in the center of the nutrient pod and then evenly covered with about 1 cm thick sieved fine soil. The imported seeds have a sterilized coating agent, and they must be dried seeds and not soaked.
??6, bed management points
(1) After sowing, in order to prevent rainwater flooding, avoid glare, high temperature, and dryness to induce virus disease, insert 2m long bamboo pieces along the ridge and bend into arched sheds, cover with a layer of shade net, and then Cover a layer of rain-proof old shed film and fix the small arch shed with a string to provide good growth conditions for the seedlings.
??(2) On sunny days, the shelter film on both sides of the small arch shed is 25cm away from the ground to allow the seedlings to cool down. Before the rainfall, the shed film should be placed on the ground and fixed firmly to prevent scratching the film.
(3) Before and after emergence, keep the surface wet, which is conducive to lowering the temperature and prevent virus disease. Generally from the third day after sowing at 5 pm on the third day, the sunny days will be sprayed with water on the seedlings evenly, and sprayers can spray 15 kg of fresh water every 6 to 7 m2.
(4) When the seedlings have emerged from the top of the seedlings when they emerge from the soil, the seeding cover soil may be too thin, and about 0.5 cm of fine soil shall be sprinkled. If the seedlings do not emerge, it may be that the seeding cover is too thick or the seedlings are short of water.
(5) Common pest control. The seedling stage is prone to damping-off and damping-off, and 80% EDPH WP and 75% chlorothalonil wettable powder can be used in the prevention and control. The 10,000-fold dilution is evenly sprayed, separated every 5 to 7 times. Spray it once more. With virus A powder 500 times every 5 to 7 days even spray twice, can prevent viral diseases. At the same time, it can also use 1.8% afordin (Coxazole) EC 2000 times, spray 3 times every 5 to 7 days or use 40% phoxim, mix 5 times of sauteed wheat bran as bait. In the evening, it is applied once every 2 to 5 days around the seedbed to effectively control leeches, cockroaches, cockroaches and ground tigers.
