Champs cellar cultivation technology is a cost-effective planting model. The main approach is: after the "cold dew" in the ground to dig a pit, "frost" to "start the winter" before and after picking buds listed. This planting mode has low cost, high efficiency, and simple management technology. The cellar with a width of 3m and a length of 10m generally has an output value of 5,000 to 6,000 yuan. Its main approach is as follows. First, sowing seedlings Citron because of frequent picking buds, rarely flowering seeds, must be from Shanxi, Henan, Shaanxi and other places to buy that year's Citron seeds, "Spring Equinox" to "Ching Ming" (from late March to early April) impotence nursery. The width is 1.2m, east-west direction. 4 to 6 days before sowing, water irrigation and spawning. Seeds of Cinnamomum camphora with 3 or 5 days before sowing will be soaked with lukewarm water of “cold and open†for 15 to 20 h (hours) before germination, and then germinated at 25 to 30°C until seed germination is possible. . For each 666.7 square meters (mu) with the amount of 1.5 ~ 2kg. Drilling after the cover soil 1.5 ~ 2cm, can also be immersed in water directly seedling without germination. 5 to 6 leaves when air-conditioning hardening seedlings. Second, transplanting planting camphor seedling height 10cm, 8 to 9 leaves when planting, generally in late May to early June. Line spacing 60cm20cm, 666.7 square meters planted 6000 to 7000 strains. When planting holes or ditch pouring. Third, the fertilizer and water management generally applies fertilizer once after easing seedlings. In the middle and late June of June, 10 to 15 kg of urea and 20 kg of compound fertilizer of nitrogen, phosphorus, and potassium were topdressed every 666.7 square meters. In case of heavy rain in summer, it is necessary to drain water in time to prevent rooting and watering in the event of drought. Fourth, dwarf treatment Summer seedling growth is strong, generally in late July to early August, when the seedling height is 1.5m or so, apply the top of the plant with PP333 or 300-500 times liquid to make the top of the plant to form a “疙瘩â€. If end buds want to germinate before the end of September, they can be applied once more. This must be controlled by dwarfing, otherwise it will affect the yield and quality of spring pods after entering the pit. If you want to buy seedlings and plant them in the pit, you must guide them to dwarfing at the nursery site. 5. When Tanaka excavates the cellar "cold dew", he digs a pit of 1m deep in the ground in the ground. The length and width may be determined according to the number of fragrant pot seedlings. The general cellar length is 10m and width is 3m. The cellar is 20 to 30 meters long and 5 to 7 meters wide. We make soil of the north, south, and the north three meters high in the pit on the pit and make a pattern of the north high and the south low, and use a bamboo pole to make a skeleton and cover a plastic film and a haystack. 6. When planting "frost" into "early winter" in the cellar, Tanaka's citron leaves are plucked out of the planting pit and planted in a cellar. Generally, about one year old seedlings are planted at about 150 plants per m2, and about two years old are planted at about 100 plants. . In the middle of the cellar, a 30-cm wide walkway should be left. If it is a large cellar, such as 20m7m, two walkways should be left. When planting should pay attention to the variety of citron, green gladiolus body is generally smooth, early buds; red citron plant body is rough, sprout late, should be planted separately. After planting a large water plant, be sure to fill it with plenty of water, cover it with plastic film and grasshopper, and properly ventilate and reduce humidity. VII. Management in the Pit 1. Temperature: Within 10 days after planting, the temperature in the shed is maintained at 15-20°C during the day and 14°C at night, and the temperature is gradually increased afterwards. In order to promote the sprouting of axillary buds, the temperature in the pits is generally controlled at 29 to 30°C during the day and 12 to 14°C at night. After the beginning of the “spring†period, the temperature exceeds 30°C at noon, and the air can be properly ventilated, and the temperature can be reduced to 26°C to close the vent. The nighttime temperature is generally not lower than 10°C. From "frost" to "early spring", there is usually no need to let off the wind. 2. Water and Fertilizer: Citron is planted in soil in pots, and it mainly depends on its own stored nutrients for growth. Generally, no fertilizer is needed. When entering the cellar, the water is poured once and it is generally not necessary to water afterwards. After the beginning of the “Spring†season, the soil moisture will be seen. If it is dry, it can be poured with water. The relative humidity of the air in the cellar is generally kept at 80% to 90%. If it is dry, it can be stored in the afternoon at the east. Spray water with 0.2% potassium dihydrogen phosphate, urea liquid for foliar dressing. VIII. Picking axillary buds Before and after the “Establishment of Springâ€, the shoots can be harvested when they reach 20cm or more. When harvesting, the top buds can be plucked from the base and bundled with corn ear bundles into small bundles. Each bundle is about 100g. Standing in the water (depth of 2～3cm) is soaked for about 10h (hours) to prevent wilting and is listed on the second day. Nine, the temperature of the seedlings after the “Clear Brightness†has been raised, and the buds have been listed on the open ground. Afterwards, the axillary buds in the pit will no longer be collected. The seedlings can pass through the wind and the seedlings can be cultivated. When the open ground temperature reaches around 15° C., it can be used before and after “Gui Yuâ€. Planted outside the pit. About 1/3 of the total root volume was cut during transplanting, the main trunk was cut to about 0.5m, and the spacing between rows was 60cm15 to 20cm. After transplanting, irrigation was performed to strengthen the management. The general survival rate was about 95%.
