The so-called cultivating cultivation is a protective cultivation method in which the strawberry is kept warm before it enters natural dormancy to prevent its dormancy, so that the plant continuously grows, and flowering results, so as to achieve extremely early ripening (harvesting in mid-to-late December). To promote the cultivation of the need to use shallow dormancy varieties such as Fengxiang, Chunxiang, Qixiang, Jing Xiang, Li Hong, love berries, female peak. The main points of promoting cultivation techniques are as follows: Planting will deep-seed the plots, spread base fertilizer and mix with the topsoil, and then open the ditch to make it. It is 20 to 25 centimeters high, 50 to 60 centimeters wide and 30 to 40 centimeters wide. In mid-September, a stable seedling with 5 to 6 unfolded leaves, a rhizome thicker than 1.3 cm, a well-developed root system, and a weight of 25 to 30 g or more was selected. Two rows of plants were planted on each plant. The plant spacing was 20 cm and 30 cm, and 8000-10,000 plants were planted per acre. When planting, the arches of the plants were backed to the side of the channel. 2 to 3 days after planting, pour 1 or 2 times a day of water, and then spray water every day until the young seedlings return to green. To keep the soil moist after easing the seedlings, promptly rake loose soil, spray 50% carbendazim 500-600 times or thiophanate-methyl 800-1000 times to prevent disease. Every half month before covering the shed, spray the medicine one time and spray it three times. The covering time of cover mulch film and shed film was at the beginning of November and the middle and late of November, and the mulch was covered earlier than the half moon of shed film. It is not good if the roof is too early or too late. It is best to do it when the local temperature drops to 15°C to 16°C. The temperature of the cover should be maintained at 28°C-30°C during the early days and 5°C-10°C at night. When the temperature is lower than 5°C at night, insulation measures should be taken. The air humidity should be controlled at 85%-90%. Flowering temperature and humidity requirements are more stringent, the general daytime temperature should be controlled at 25 °C, the maximum does not exceed 30 °C, night temperature control at about 10 °C, not less than 8 °C, air humidity control in 50% to 60%. The daytime temperature during Fruit enlargement and ripening is controlled at 20°C to 25°C, nighttime is controlled at 8°C to 10°C, and air humidity is controlled at 60% to 80%. After 20 days of incubation, a 10 ppm gibberellin solution was sprayed. Gibberellin has the effect of promoting plant growth, breaking dormancy and making it mature earlier. When the buds appear 35%, spray 5ppm of gibberellin solution again. The spray should be uniform, and the heart and leaves should be re-sprayed to promote the opening of the top flower buds. Fertilizer is based on the application of base fertilizer (5000 kg of fertilizer per acre Shinong), and 20-25 kg of compound fertilizer is applied. During the canopy period, four top dressings were performed. After the first flower buds were spit out on the top inflorescence, the second time during the fruit expansion period, and the third time the top fruit was harvested, the fourth time was harvested at the top fruit stage. Usually topdressing once every 20 days, combined with irrigation. Plants with 3 shoots usually have 3 to 5 inflorescences and a large number of grape stems. The functional leaves should be preserved from 10 to 13 and the stem, old leaves and diseased leaves of the grapes should be removed in time to prevent nutrient consumption and facilitate ventilation. Light. Pollination A greenhouse plant 2 to 3 varieties, pollination each other or with a brush for artificial pointing. You can also set up a beehive every 1000 square meters, using bees or other insects to pollinate. Thinning fruit in the young fruit timely sparsely deformed fruit, disease and fruit, and in the fruit under the care of fruit. The treatment of greenhouse strawberry insect pests is lighter, mainly to prevent gray mold, powdery mildew and other diseases, can be sprayed once every 15 to 20 days 50% carbendazim WP 2000 times.
