Orange is a common fruit, almost everyone has eaten it, and orange tree is also more common in life. Orange tree is an evergreen small tree, evergreen all the year round, the branches and leaves are neat and dense, looking very beautiful from afar. In spring, fragrant flowers bloom all over the trees, and in autumn, yellow fruits are covered with branches, which makes people salivate. But want orange tree to be able to be fruitful, breeding is very important, the following small series for you to introduce the cultivation methods and precautions of orange tree.
Orange tree cultivation method of orange tree (basic knowledge): the best growing soil: orange tree likes sunshine, suitable for growing in fertile, loose, slightly acidic, well drained sandy soil.
Growth humidity requirements: like warm environment with a certain humidity, basin soil should be kept moist, but the basin can not be ponded. When the weather is hot from summer to early autumn, in addition to watering the basin, it should also spray water on the site around the basin to keep it moist.
The best growth temperature: orange trees like warm, shade resistant, sensitive to temperature than light. The most suitable growth temperature is 26 ℃ and 23-34 ℃.
The best growth light: orange is a fruit with strong shade tolerance, but good sunshine is still needed for high quality and high yield. Generally, areas with 1200-2200 hours of sunshine can grow normally.
Orange tree cultivation orange tree attention: fertilizer: Orange like fertilizer, usually should be more thin fertilizer. The plant was fertilized with liquid fertilizer once before germination, and then every 7-10 days after that, liquid fertilizer with nitrogen fertilizer as the main component was applied once every 7-10 days to promote the growth of branches and leaves and spring shoots. After each picking, fertilizer should be applied in time to make the branches mature earlier. During the growth of oranges, some cake fertilizer can be sprinkled on the basin surface, so that every time watering, there are some fertilizers infiltrating into the soil to enhance the fertility. After autumn, the fertilization was reduced to avoid excessive nutrition of plants, promote the development of autumn shoots, and compete with fruits for nutrients, resulting in fruit drop.
Key points of watering: different fruit trees have different requirements for pH value of water, which is generally 6.5-7, which can be corrected by ferrous sulfate. The difference between water temperature and soil temperature should not exceed 5 ℃. Watering in the growing season should be conducted before 10:00 a.m. or after 4:00 p.m. Water should be poured once a day on sunny days in summer. If the soil is dry, it should be watered once a day. In spring and autumn, water should be poured once a day. In early spring and late autumn, it should be watered every 2-5 days according to the soil moisture. In winter, water should be controlled.
Pruning tips: (1) orange tree is a kind of fruit that needs pruning. If the orange tree is not pruned, it will rarely grow strong next year, and the yield will not be high. The pruning of orange trees is usually done once in winter after the fruits are harvested. (2) In the future, when an orange sprouts, it will grow a lot of new branches. You can also cut off the branches that are too small, too thick, or too dense. At the same time, you can also cut off some diseased branches. This is especially beneficial to the production of oranges. More flowers and more fruits will be produced in the coming year.
Pot soil replacement: due to the lack of potted soil and limited nutrient supply, the potted oranges will be weakened year by year due to the lack of soil fertility for many years. In order to keep the oranges blooming and fruiting every year, they must be replaced. The optimum time for pot soil replacement was half a month before the orange sprouted. Before replacement, prepare a basin that is like the one larger than the original one. Take the orange out of the basin and do not crush the mud. Cut off 1-2 cm thick topsoil along the mud mass, cut off the dead and rotten roots, and cut off the 1 cm thick soil at the bottom of the mud ball, and take out the tile embedded in the bottom of the basin. The drainage hole of the new basin should be placed with tiles. First, a layer of 2-3 cm thick drainage layer should be paved, and then a layer of 4-5 cm-thick nutrient rich culture soil mixed with a small amount of calcium superphosphate. Then put the orange mud ball into the basin, fill it with culture soil to the mouth of the basin, slightly compact the basin soil, pour enough water for root setting, place it in a ventilated and semi shady place, and put it back to the original place after a week for daily management.
Breeding points: seed propagation, grafting propagation, cutting propagation
(1) Seed propagation: first prepare the excellent orange seeds, and then turn over the ground, so that the oranges grow out and then slowly cultivate them.
(2) Grafting propagation: we can first raise some orange seedlings, and then cut off the branches of some excellent orange varieties, and then carry out grafting, so that we can plant excellent orange varieties.
(3) Cutting planting: some suitable for cutting branches into the soil, and then add some rooting elements, so that the orange tree is very easy to grow.
Pest control: it can be sprayed with Carbendazim and other sterilization and disease prevention drugs; for insect pests, it is necessary to spray corresponding insecticides, for example, red spider and rust spider can be sprayed with 50% mite agent EC, that is to say, death; 5% imidacloprid EC can be used for 2000-3000 times of spraying; scale insects can be sprayed with 1000 times of 40.7% lesborne; aphids can be sprayed with 50% Pirimicarb 1500 times Etc.
Orange tree culture orange tree experience: orange tree is relatively easy to survive tree species, but want to bear more and larger fruit, you need later management and maintenance. Orange trees like a humid environment. After planting, they should keep the garden moist. This is one of the most important links in orange tree management. Pruning is particularly important if you want young trees to bear fruit early and harvest well. Understand the management method of orange tree, friends, please see if your orange tree has the right management? If not, correct it quickly and wait for the golden orange harvest.
