Northern cultivation management

The cultivation and management techniques of fingered citron are introduced as follows: (1) Keep a good planting nest. In winter, according to the space of 60 square meters, dig three bergamot nests with depth and width of 1 m on the ground. Within 70 cm of the lower layer, apply 50 kg of human excrement or soil miscellaneous fertilizer, or 3-5 kg of Bika compound fertilizer and mix with the soil to make it fully decomposed. The upper layer is 30 cm covered with plain soil in the garden or soil in the forest, so as to raise a fat nest for the final planting of melon seedlings in the next year.

(2) Accelerating germination and raising seedlings.

(1) There are three simple methods to accelerate the germination of fingered citron in north China: one is to accelerate the germination of fingered citron in sweet potato kiln, and the temperature in1February is between 8 ~10℃, which is suitable for heat preservation and germination of fingered citron. The second is to accelerate germination and seedling raising in vegetable greenhouse. In winter, the temperature in vegetable greenhouse is between15 ~ 30℃, which is the best temperature for fingered citron seedling. Before and after the severe cold in the middle and late January, the seed melons were moved into the shed to accelerate germination, and when the germs grew fibrous roots, they were planted and raised in the shed. Planting fingered citron in the shed will be directly planted in 10, and the seedlings will be put on the shelves, which will blossom and bear fruit in the early stage, and the shed will be uncovered in the spring of next year, and the melons will be available in the market in late May to early June. The third is to accelerate germination and raise seedlings in a heated room. Choose a small room with normal heating and use nutrition pots, flower pots or wooden boxes to raise seedlings. Indoor temperature shall be kept between 15 and 25℃. (2) Intensive embryo breeding. When the embryonic base grows well and begins to take root and sprout. Gently pull the suture line of the seed melon, stir the embryo with a sterile pick, gently take it out, and plant it in a small nutrient bowl or prepared nutrient soil to raise seedlings. (3) Cutting seedlings with cluster buds. A fingered citron can grow many clusters of buds, ranging from two or three seedlings to six or seven seedlings. These clumps of buds can grow to about 10 cm in April and May. (3) Set up scaffolding. (1) Set up a 2.5m ~ 3.0m flat frame or arch corridor shed. (2) Chaenomeles intercropped in orchards can be built with trees and nets according to the characteristics of various tree crowns such as grapes and apples. (3) Family courtyard, according to the natural situation of courtyard walls and wood and bamboo, is connected with each other to form a frame. (4) The melon frame on the roof can only be built with a low frame of 1 meter high. No matter what scaffolding, only one or two main vines of bergamot are left under the scaffolding to promote the growth of the vines of future generations and increase the yield. (4) Strengthen the management of water and fertilizer. In early spring, fingered citron seedlings planted in the plain soil of melon nest should be watered around the roots every day to keep the ground moist. Don't rely on melon to fertilize and water urine during seedling stage to prevent seedlings from burning. When the main vine grows to about 1 m, a small amount of human excrement, urine, soil miscellaneous fertilizer or chemical fertilizer is applied in the open-loop ditch 30 cm away from the melon seedlings to promote the seedlings. In the dog days, every 10 day, water will be flooded under the ground, and human excrement and urine and compound fertilizer will be applied with the water, so as to attack stems and promote vines. In hot weather, pay attention to spraying water on leaves, which will not only cool down but also increase leaf fertilizer. After beginning of autumn, spraying Yemianbao every 10 day. (five) timely harvesting and storage of melons. Picking melons that grow for 15 days in the early stage should be timely. Picking melons should be handled with care. After winter, they should be placed indoors at about 5℃ to avoid freezing injury. As long as it is properly stored, the melons picked in September and October can be stored for seven or eight months.
