What management work needs to be done before planting mangoes in the field?
1. Marking out Marking out and digging holes: The orchard is first plowed twice and harrowed twice, with deep turning and ripening to a depth of 30cm. For orchards on hillsides, planting is done along the contour. First, from top to bottom, establish a vertical baseline, and according to the baseline and the plant spacing, mark out the planting points for two contour planting rows at the middle and foot of the hillside to the left and right. Then, using two points to form a line, mark out the planting points for the other contour planting rows. For flatland orchards, use the main road and branch roads as baselines and mark points according to the specified plant and row spacing, with each planting row parallel or perpendicular to the roads. The planting hole size is 80×70×60cm, and holes should be dug 2-3 months before planting.

When it bloomed, cluster after cluster, like little bells hanging on the plants, so beautiful! So do you know how to grow such a beautiful lily of the valley? Let the editor teach everyone to learn together!</p><p></p><p><strong>How to grow lily of the valley</strong></p><p>1. For open-field cultivation of lily of the valley, it is best to choose deep-plowed, fertile planting ground. When planting lily of the valley, cover with soil to more than 5 cm, and water thoroughly after planting. Field-planted lily of the valley needs to be divided and replanted once every 3-4 years.</p><p>2. During the growing period, lily of the valley should be kept with loose, moist soil at all times, and apply a fully fermented topdressing once each in early spring and late autumn.</p><p>3. After lily of the valley sprouts in spring, apply topdressing once every 15 days. Pay attention to watering during drought, and stop fertilizing after the flower stems emerge.</p><p>4. After the lily of the valley flowers fade, promptly cut off the flower stalks, then apply topdressing 1-2 more times.</p><p></p><p>5. In late autumn, after the aboveground parts wither, cover with leaf mold and cow manure to protect the rhizomes and their dormant buds for overwintering in the open field.</p><p>6. For potted lily of the valley, plant rhizomes that have been cold-treated, maintain the temperature at around 18-20°C throughout the cultivation period, pay attention to fertilizer and water management, and keep the soil moist. After about one month, the lily of the valley can bloom.</p><p>7. After lily of the valley blooms, it is best to cut off the stems and branches early so that nutrients are concentrated and supplied to the rhizomes. For potted lily of the valley, choose plump and large rhizome buds, plant 4-5 buds per pot, and repot once a year.</p><p></p><p><strong>Benefits of keeping lily of the valley at home</strong></p><p>1. Lily of the valley has a sterilizing effect. Similar to plants such as roses, lemons, and carnations, its rich fragrance and the oils it releases can kill bacteria and have a protective effect on the people at home.</p><p>2. It acts like an air purifier. As everyone knows, flowers and plants, besides beautifying the home, can also purify the air. Lily of the valley is no exception. Although it is not as powerful as some plants at absorbing toxins, it should not be underestimated. It can absorb carbon dioxide, increase negative ions, and its fragrance can also make the air fresh and healthy.</p><p>3. Relax the mood. Fresh flowers can improve a person's physical condition, relax the mind, and delight the spirit.</p><p></p><p><strong>Precautions for growing lily of the valley and its medicinal value</strong></p><p>1. Precautions: Greenhouse cultivation is prone to pest and disease damage. The commonly seen ones are fungal diseases such as stem rot, anthracnose, and leaf spot. Normally, copper-based fungicides should be used regularly for prevention and control, and collecting seeds from diseased plants for propagation is strictly prohibited. Once diseased plants are found, they must be immediately destroyed and removed to prevent spread. If brown spot disease occurs, spray with 75% chlorothalonil wettable powder at 700 times dilution. Lily of the valley cannot be grown together with lilac or narcissus. If placed together with lilac, it will cause the lilac to wilt; if placed together with narcissus, both the narcissus and lily of the valley will wither.</p><p>2. Medicinal value: Lily of the valley has the effect of promoting blood circulation and dispelling wind, and is mainly used for heart failure, edema, strain injuries, abnormal uterine bleeding, leukorrhea, and traumatic injuries.</p><p></p><p><strong>Propagation and cultivation of lily of the valley</strong></p><p>1. Propagation</p><p>Lily of the valley is usually propagated mainly by division, and can also be propagated by seed. The best time for division propagation is in spring and autumn. On the rhizomes of lily of the valley there are young buds of different sizes. Cut off each terminal bud together with a piece of rhizome and plant it. Seed propagation can be carried out in autumn, and sowing the seeds from fully ripe berries is enough.</p><p>2. Soil planting</p><p>Site selection. Choose shady hillsides, woodland with relatively thick humus, or grassland. Cut strips along contour lines or across the hill, with a strip width of 1.5 m, a spacing between strips of 2 m, and a row-to-hole spacing of 50x20 cm. Dig holes, break up the soil, firm it, and shape it into a steamed-bun shape.</p><p>Planting. Deep-plowed, fertile soil is best. It needs to be moved to another site and replanted every 3 to 4 years, or rotated with other flowers. The planting spacing between plants and rows is 25 to 30 cm, with 2 to 3 buds per clump, covering with soil 5 to 6 cm deep, and watering thoroughly after planting.</p><p>3. Potting</p><p>In November, choose plump and large rhizome buds, store them at 3°C to 5°C for 14 to 21 days, then take them out and plant them in pots, with 4 to 5 buds per pot.</p><p></p><p>So growing lily of the valley actually requires attention to so many things! Although lily of the valley is toxic, as long as we pay attention in daily life, keeping it at home still has certain benefits. We should not ignore its value just because of its toxicity!</p>

Apricot trees can also be transplanted in spring, but they must not be transplanted when the ground is frozen, as this will affect the growth of the apricot tree. The transplanting time also varies with the size of the apricot tree.
