Planting bergamot, with less investment, quick effect, short cycle and high profit, is a very choice for developing characteristic agriculture to get rich. Bergamot can be divided into potted plants and ground plants. Potted plants can be planted1000 ~1400 pots per mu, and porcelain pots, earthen pots and plastic pots can be selected. For ground planting, 400 ~ 600 plants can be planted per mu. Potted bergamot needs to be watered every day in summer, and it should be concentrated in the greenhouse during the winter. As a result, more than three bergamot bonsai can be used. Planting bergamot in the ground is simple and convenient to manage, without watering and fertilizer, and the fruit is large and the yield is high. The dwarf bergamot bonsai can be cultivated by layering method. To plant bergamot, you should choose a place with convenient transportation, strong light and moderate air circulation. Fingered citron is a plant that likes warm and light, and10 ~ 31℃ is the most suitable growth temperature. If it is below 0℃, it needs to be wintered in a greenhouse, and 4 1℃ can grow normally. Loose, fertile sandy soil with good air permeability and water permeability should be selected; Appropriate moisture is needed, too much will lead to mildew roots, too little will lead to defoliation. Potted soil should be "dry and watered, wet and not watered"; Planting bergamot in the ground can do a good job of drainage. Bergamot is almost disease-free, and pest control is simple, just "drug the insects". The bergamot can bloom 3 ~ 4 times a year, and the fruit maturity usually takes 3 ~ 4 months. The maximum yield is 23 kg per plant, and the maximum weight per plant is 26.5 kg. Taking an acre of land as an example, the cost of each plant is 3 yuan, and seedlings are introduced 1000 plants. In the first year, 750 kilograms of fresh fruit and more than 400 potted plants are produced per acre, with a revenue of more than 30,000 yuan and a profit of more than 25,000 yuan. After artificial breeding, grafting and transplanting, the profit can be multiplied. The highest net profit per mu can reach 10 million yuan. Cultivation techniques Jinhua fingered citron is propagated asexually, and the main methods include cutting, grafting, high pressure and tissue culture. Because fingered citron is parthenocarpous and has no seeds in the fruit, it is impossible to propagate fingered citron through sexual propagation under natural conditions. First, seedling cultivation 1, seedling transplanting and seedling cultivation should use sandy loam, and the field with higher fertility is better. After intertillage and weeding, apply 5 ~ 10 kg of calcium superphosphate or calcium magnesium phosphate fertilizer or compound fertilizer10 kg per mu as base fertilizer. Fertilization may not be required in the whole seedling cultivation stage after applying sufficient base fertilizer. Seedlings should be cultivated and planted at a distance of 20x20cm. After transplanting, they should be watered once, and they can survive after 0 ~ 7 days. Transplanting should not be carried out in high temperature season or winter. 2. The fingered citron seedlings for the purpose of shaping bonsai production should begin to be reshaped during the seedling cultivation period. Generally, when the new shoots of the seedlings grow to15 ~ 20cm, a strong new branch is selected as the main stem, and after the new shoots are pulled out from the branch, 4 ~ 6 new shoots growing in different directions can be selected as the first-level branches for preparation. When the new shoots grow to about 20 cm, 3 ~ are finally selected. After a year of field cultivation, the shaped plants can be basically cultivated. 3, according to the actual production and the physiological characteristics of bergamot, the pot is usually arranged in August ~10 or March ~ May of the following year. The method of potting is the same as other plants. Fine sand can be used as potting soil, and peat, perlite and vermiculite can also be used as media for cultivation if conditions permit. Second, the management of potted bergamot (1) water management: bergamot is afraid of waterlogging and is not tolerant of drought. When supplying water at ordinary times, it should be based on the degree of dryness and wetness of the basin soil, so as to achieve "no watering, but pouring thoroughly". The high temperature and dry season from July to August is in the growth period of bergamot fruit and the germination period of autumn shoots, so the water supply should be guaranteed, usually once in the morning and evening, to ensure the safe overwintering and flower bud differentiation of bergamot. (2) Fertilizer management: the bergamot is mainly farmyard manure, and the common fertilizers are decomposed manure, human excrement and urine, cake manure and compound fertilizer. With potassium dihydrogen phosphate, etc. In March, the fermented human excrement and urine was mixed with thin fat water and poured every 7 ~15 days. (3) Flower thinning and fruit thinning: Jinhua bergamot mainly focuses on the yield of spring flowers and summer flowers, so as to maintain high quality and stable yield and adjust the growth and development of bergamot. Flowers should be thinned and fruit thinning should be carried out according to the age and tree vigor. Plants with older trees or weak trees are prone to bear fruit in spring flowers. Because of the high quality of spring fruits, more spring flowers and fruits can be kept, and at the same time, Xia Guo of summer flowers should be thinned for good nutritional growth of plants. For plants with young trees or vigorous growth, although there are many spring flowers, the original fruit setting rate is low. In order to feed the waste of nutrients, we should pay more attention to thinning spring flowers and leave more summer flowers in Xia Guo to ensure the yield. (4) Pruning: The pruning of bergamot is mainly in spring, summer and autumn. In spring, combine with the shed, and carry out moderate pruning, mainly to cut off the long branches, branches in the wrong direction, diseased branches and dead branches. Pruning is carried out at the end of June, and summer pruning is the main part of the whole year's bonsai shaping, which can be pruned according to the specific requirements of bonsai, generally requiring the plant branches to be evenly distributed. Autumn shoots pruned in mid-August in autumn are the fruiting branches of the next year, so we should prevent them from growing in vain and promote thickening and aging to facilitate flower bud differentiation. Third, pest control There is generally no disease in the growth process of bergamot. The pests of bergamot mainly include red spider, leaf miner (painting insect), butterfly with jade belt and gray moth, etc., as well as scale insects and aphids. Red spiders can occur all year round, so we should always check the back of plant leaves and kill them with acaricides when there are 2 ~ 4 red spiders in each leaf. Leaver moth mainly occurs on the tender leaves of autumn shoots. Because its early body is small and it dives into the leaves, it hurts mesophyll, so prevention should be given priority to. 3 ~ 5 days after summer pruning, the chemical control was applied, every 5 ~ 7 days 1 time, 3 ~ 4 times in a row, and stopped after the new tip leaves were keratinized. Fourth, the management of local cultivation of bergamot takes picking fruits and grafting small bonsai of bergamot as the main production purpose, and it can be cultivated in the way of local cultivation. Ground-planted bergamot has developed root system, rapid plant growth, large fruit bearing capacity and high yield. And the management is relatively extensive, especially the management of fertilizer and water is relatively easy, and it is not easy to hurt roots and seedlings. The management of ground planted bergamot is basically similar to that of potted plants, but special attention should be paid to the following aspects. 1, fertilizer supply The fertilizer supply for fingered citron cultivation is mainly based on applying sufficient base fertilizer. Every year, in September ~10, 500 ~1000 kg per mu can be applied, mainly in furrow. At ordinary times, depending on the plant growth, moderate topdressing. 2. Depending on the climate and soil water content, the water supply area can be planted with bergamot. Generally, the soil can be wet without irrigation all year round. In rainy season, ditch and drain in time to prevent water accumulation in the field. 3. The fingered citron planted on the ground for more than 4 years has entered a prosperous period. Because of its large tree body, well-developed root system and sufficient supply of organic and inorganic nutrients, more flowers and fruits can be reserved appropriately, and generally the fruit per plant should be controlled at10 ~15 kg to ensure stable production and high quality. 4. To prevent fingered citron from growing in vain, which will easily lead to the phenomenon that only long branches do not blossom and bear fruit. The supply of fertilizer and water should be controlled, and the growth of nutrition should be properly inhibited to prevent the branches from growing in vain. It can be used to control the excessive growth of branches and the division of flower buds.
