First, the site selection: Choose a flat geothermal, sunny ventilation, adequate water conditions, convenient drainage and irrigation of fertile soil construction shed better. Second, the construction of shed technology: Shelf room north to south, generally 70 meters long from east to west, north-south span of 7.5 meters. The brick structure has a back wall with a rear wall 0.37 meters wide. The rear wall has a semi-hollow structure with three rows of pillars. It can also use cement forming components. The back wall has four heating furnaces and a flue. The addition of the coal furnace mouth is outside the back wall. , ensure no smoke in the shed. The east-west direction was tightened with No. 8 wire 11-14, and the walls on both sides were solid brick walls. The width of the wall was 0.37 meters, and the east-west pillars were separated by 3 meters. Third, the choice of varieties: choose a strong adaptability, easy management, good quality, variety, such as Cardinal, Sa Bensha, Salsa and so on. Can also be purchased finished grafted seedlings four, fertilization and close planting requirements: Rose planted before applying sufficient base fertilizer, and then poured into the ground after the well-being. The north-south direction is 畦, the width is 1 meter, and the length is limited to the width of the shed. Each pod can be planted in two rows with a spacing of 0.4 meters and a spacing of 0.3 meters. Generally, 3-7 plants per square metre are appropriate. V. Post-planting management: Watering immediately after planting, pouring once every 3-4 days, and pouring three times. Slow fertilization is forbidden. After irrigating, timely cultivating, loosening and weeding should be performed. Pruning is an important management measure for the anti-season production of roses. From the end of May to September, it is forcibly dormant, leaves only leaves for photosynthesis, accumulates nutrients, erases the upper shoots at any time, but retains the foot buds at the base, allows them to grow but does not bloom, and the upper buds germinate and eradicate. . From September onwards, the whole plant leaves only one branch with weaker branches to support the branches, and the remaining branches will all have three short shoots. After the branches are established, they will be cultivated into flowering branches. The upper foot buds will remain, and the upper buds will be wiped off. Lei can cut flowers. When cutting the flowers, the three buds at the base remain short and repeated. Can produce 5-6 years, high yield period in the 2-4 years. The length of fresh cut flowers is generally 80 cm. Sixth, winter management: The temperature of the winter shed is maintained at 15-28 degrees, and the fire can be raised at a proper time. There must be no smoke in the shed. The daily illumination time is required to be 8-10 hours. The film will be removed at 8:00 in the morning and released from 10 a.m. to 1 p.m. at 15:00 and covered at 5 pm. VII. Pest Control: Rose disease mainly includes powdery mildew and black spot disease. It is necessary to use drugs for prevention and control in time. Chlorothalonil, Thiophanate-methyl triadimefon and other pesticides can be used alternately. Insect pests are mainly spider mites and aphids, and pesticides such as phytotoxicity and omethoate can be used for timely prevention and control.
