First, quickly complete sleep. In late October, after the citron has fallen into the fallen leaves, the seedlings will be raised in time. When the seedlings are raised, they shall be provided with lateral roots. The main root shall be no less than 40 centimeters and the lateral root shall be no less than 30 centimeters. 1m, 0.5m), the scented citron shall be placed in the shade for prosthesis, cultivated soil, irrigation, covered grass rakes, grass scorpion shall be sprinkled regularly to prevent the saplings of seedlings from drying out, and the root system should not be exposed. After easing the seedlings, the citrons completed the dormancy period after about 20 days.
Second, buckle sheds and soil preparation. In the late October, the shed is shed, and the Mushi quality manure feces or chicken excrement 15000 kg, compound fertilizer 50 kg, urea 10 kg, deep soil 30-40 cm, so that the soil is evenly mixed, then leveling, made of 1.2-1.5 The width of the meter is north-south and it is 30 centimeters wide and 15-20 centimeters high.
Third, cultivation time and planting method. The dormant seedlings were transplanted to the greenhouse in mid-November. When planted, they were planted from north to south according to the height of the seedlings. The depth of the roots was 5-10 cm higher than the base of the stems, and the planting density was every square meter. 100 plants, immediately after planting watered, if there is rooting and lodging phenomenon, should be timely soil and righting, and then spray gibberellin to induce its early germination.
Fourth, reproductive period management. The proper temperature and humidity in the shed are the main factors for the high yield of Toona sinensis. The temperature during the day should be kept at about 25°C and not less than 15°C at night. After starting the shed, in order to slow down the seedlings, the daytime light should not be too strong. The grass curtain should be put down at noon and then lifted when it is weak. At noon on sunny days, we need to cool down. In the winter season, it is necessary to uncover the grasshoppers in time and pay attention to the greenhouse insulation. If the temperature is too low at night, pay attention to warming. The method of warming is to put a hot water bottle every 15-20 meters. This will not only increase the temperature but also increase the humidity in the shed. During the whole growing period, we must pay attention to maintain a high humidity in the shed and must not be dry. Under good humidity and temperature, about half a month later, the citron can germinate, and it can grow to 20-30 centimeters in about a month. At this time, it can be harvested and marketed (this time is mid-December). After harvesting the first crop, it is necessary to cooperate with water-saving irrigation and efficient nitrogen fertilizer, about 10 kilograms per mu, after harvesting a second crop in more than 1 month, it is exactly the middle and late January, and it will be listed before the Spring Festival so that before the Spring Festival, Two crops can be harvested, accounting for two-thirds of the total output during the growth period, with considerable benefits.
