Prepare cultivation soil and flowerpots before cutting orange pots. Oranges are common fruits and need to be preserved in the field. The large volume of potted plants leads to the relative reduction of root nutrient area, which is easy to make underground and aboveground parts malnourished, thus affecting the normal growth and development of potted citrus. Therefore, in order to make potted plants cut alive and bear fruit, not only the cultivation management technology is strict, but also the cultivation soil needs to be scientifically prepared. Prepare the culture soil one month before potted plants. It can only be used after decomposition. According to the growth characteristics of oranges. The cultivated soil should be loose, fertile, with high humus content, lasting fertilizer effect and easy drainage. The ideal formula of culture soil is that humus soil, horse manure, garden soil, coarse sand or slag are mixed in the ratio of 2: 1:2: 1. And use human excrement to seal the rape and decompose it into a boat for later use. When planting for the first time, you can choose a smaller pottery pot with a diameter of 30 cm and a depth of 25 cm. When flowering, it can be changed to a caliber of 35 cm; A large earthen basin with a depth of 30 cm.
2. Time and method of potted plants
The suitable time for potted oranges is the same as that for field planting. Before potted citrus, the seedlings should be dug out and aired for 1-2 days to make the roots dehydrated and soft, which is convenient for pruning and planting; Before planting, put the flowerpot into the pool to absorb enough water; When planting, first lay tiles on the drainage holes at the bottom of the basin to prevent soil leakage; Then spread pebbles or waste brown rope with a thickness of 2-5 cm to facilitate drainage. Before planting, the orange seedlings should be pruned to balance the above-ground and underground parts; Beautiful and generous appearance; But also convenient for cultivation management. First, cut off the dead leaves and excessively long roots, disinfect the roots with 1% copper sulfate solution for 5- 10 minutes, then place the seedlings in the center of the basin, and compact them by hand while filling them until they are 3-5 cm away from the upper edge of the basin. After potted, the pot surface can be matched with Taihu stone, quartz stone, bamboo shoots and citrus plants, which not only increases the beauty of potted oranges, but also makes the pot surface full of green and full of vitality, and can also play the role of moisturizing and heat preservation.
water
Potted plants must be watered in time to maintain the normal water demand of snake gall because of their small capacity, little soil and limited water holding capacity. Water once after cutting, and water once every 3-4 days after pulling the soil wet to keep the potted soil moist. If the amount of water. The soil is too wet. It is easy to make the branches and leaves white and long, too wet or stagnant for a long time will rot the roots. Especially in summer and autumn, we should control the humidity of the basin soil, do not dry it, and do not water it. When it is dry in summer, boil water in the morning or at night, and don't water it as long as it is not too dry in autumn. Too wet buds flourish in autumn and will not bloom in spring.
Step 4 apply fertilizer
The nutrients in the basin are limited, and only timely topdressing can ensure the normal growth and development of citrus. After soaking fermented sesame, peanut and bean cake, topdressing can be started from the following spring. Mix water when applying, and apply water 1-2 times a week during the growth period; Water can be poured once a day before and during flowering; After the flowers wither, they should be cultivated and lightly fertilized or sprayed on the leaves, and no topdressing is needed during winter dormancy.
5. Drainage in summer
Oranges should avoid long-term rain, excessive humidity and hot summer. If they encounter long-term hot and humid weather, their leaves will be burnt and their roots will rot. In hot summer, potted oranges can be moved under the seedling shed for shade, or buried in the soil for heatstroke prevention and cooling, and good drainage and ventilation can be maintained. When there is no rain, water should be sprayed on the branches and leaves every day to increase the air humidity, so as to ensure the water supply during the flower bud differentiation period of citrus. Pay attention to drainage in rainy season, and pour down the flowerpot in rainy day to prevent water from accumulating in the flowerpot. Spraying 10- 15 days after flowering 150 times bordeaux solution or 800-l000 times Tobezin solution to prevent and control diseases at that time. Orange root is sweet and vulnerable to ants or grubs. It can be killed by replacing water with 1000 times dichlorvos solution.
6. Pruning and wintering
In order to improve the ventilation and light transmission conditions of citrus and concentrate nutrition, it should also be trimmed after falling leaves in autumn and winter. Cut off too dense branches such as parallel mouth, cross mouth, introversion and insect-proof mouth to keep the plant in a beautiful shape. Late autumn and early winter. Pot-cut oranges can be buried in the soil, with branches exposed outside the ground soil and the top protected by grass or soil. Others put the flowerpots directly into the cellar for the winter, remove the plastic film in the spring of the next year, go out of the kiln as usual, and put them in a ventilated and sunny place to strengthen the management of fertilizer and water; Let it bloom naturally. Others are placed in greenhouses or plastic greenhouses to promote early flowering according to holiday needs. In order to make potted oranges more beautiful, concise and elegant in decorative modeling; When the flowers are about to bloom, you can put painted pottery and porcelain pots outside the original pottery pots; Put it on a delicate basin frame or table in a spacious and bright hall or purlin.
