Omnicorn is a very popular species. It is mainly located in southern china. Oxylene is rich in many nutrients and can improve blood circulation. There is also a certain area of citrus cultivation in china. The management of citrus cultivation is very important. When's the umbilical? What do you have to pay attention to when you water? Let's find out。
I. Choosing an orange seedling
For high-quality umbilical trees, the varieties are required to be pure, the branches on the ground are solid and full, and the leaves are green and bright. The seedlings are above 35 cm and have three branches. Roots are well developed, with principals of 15 cm or more, with more roots and fewer broken roots. There are no quarantine pests or other pests. Omnicorn seedlings can be grown or purchased nearby. The planting of seedlings should be done with as little damage as possible to the roots and should be done immediately after the seeding. As far as possible, seedlings are free of viruses, containers or large seedlings。
Ii. Oxygen transplant time
The timing of an orange transplant should be determined by its growth characteristics and local climatic conditions. In general, it can grow after the bud matures until the next bud is collected。
The planting time of the seedlings in the field is usually divided into spring and autumn. The spring broadcasts were generally conducted between the end of february and march. During this period, spring sprouts became greener, temperatures increased and rainfall increased, making it easy to survive and subtract from water-fed autumn plantings. Autumn seeding usually occurs from the end of september to october after the autumn season. Temperatures remain high and soil temperatures are adequate. As long as the soil is hydrated, the roots of seedlings will heal faster after sowing and new roots can grow again. This will contribute to the normal sampling of spring branches in the following year。
2. Timing of planting of false seedlings: these are generally not seasonally limited and can be grown at any time. However, during the summer and autumn dry season, low rainfall and inadequate water supply can affect survival rates. The best time for planting is therefore from mid-may to mid-june, when spring sprouts mature。
Iii. Density of seeding of umbilical oranges
Omnicorns are usually planted in flat ground, layered soil, high fertility and well-managed areas. This is due to the fact that, in good environmental conditions, individual growth and individual plant development are more favourable. The space between plants can be 3 m x 4 m, with approximately 55 plants per acre. In mountainous areas, plains and dry areas with low rainfall, an appropriate distance of 2. 5 m x 4 m and an area of approximately 66 plants per acre could be used。
Iv. Oxylene cultivation methods
1. The method of seedlings in daejeon: before planting an umbilical orange, remove the thin membrane, repair the roots and buds, smooth cut the cuts and cut the dead branch, the sick branch and the buds fall into the ungrowing branch. At the time of planting, the roots should be covered with thin yellow mud. Slurry concentrations must be tested by hand. It's appropriate to see no fingerprints on your hands. The appropriate amount of cattle excreta added to the mud and a small amount of fertilizer to promote rooting. At the time of planting, two people had to plant the seedlings in a hole in order to ensure a smoothing of the roots, which would allow the new group, which naturally extended the roots, to stretch slowly, and then fill the soil evenly and pour enough water. Then cover a thin layer of soil to help keep it wet。
Ii. Methodology of enforcement power: a pit is dug at the place where the seedling is grown before the planting of the citrus. The plastic sheeting is removed, the seedlings of the cups are placed in the centre of the pit, filled with nutrient soil around the plate, and pressure is light. It then crushes the earth into a dish about 1 metre in diameter and pours water into it. The height of the floor better be exposed to the ground. Finally, the planks cover straw in order to prevent weed growth and keep the soil loose and wet。
The importance of irrigated umbilical oranges. When do you need them? What are the effects of watering
I. Methodology for definition of owners in the orange watch
At the time of the growth of the umbilical orange, when natural precipitation does not reach its growth and results, water must be poured. The right irrigation time does not wait until the fruit shrinks in the umbilical form, when the blades bend, but rather to complete the water before the umbilical oranges are affected by the shortage, and to establish a period of irrigation in the citrus orchards. When the fruit ceases to grow, it means that it takes some time for the fruit to swell. Or take soil layers of 5-20 cm, border or sandy, and hold it tight. It's just a bump. If it was a clay, it could be squeezed into a pile, but it would split and split. It's time for water。
Ii. Watering time for belly button oranges
High-temperature dry season: during the summer and autumn dry season, particularly in july and august, high temperatures and high evaporation levels. During this period, large quantities of water are required when the oatmeal fruit expands rapidly and grows in the autumn. Water scarcity inhibits growth, affects the development of fruit and even results in the loss of large quantities of fruit. The high temperature and drying period from july to august is therefore an important period for the water of the umbilical oranges。
The flowering period and the physiological outcome period: the temperature is as high as 30°c or higher during the flowering period and the physiological fallout period, or when the hot, dry air is found, it is easy to cause large amounts of flowers and fruit to fall and must be watered immediately or sprayed from the tree crown. The effects are significant for the preservation of flowers and, in particular, for the prevention of abnormal blooms and fallouts。
3 the later stages of harvesting the fruits: since the umbilical oranges contain a large amount of water, the trees, after harvesting the fruits, have been able to absorb a large amount of water, and the water deficit in the debalancing pristine state, combined with the dry climate, can easily cause many leaves to fall. The fast-recovering tree has reduced its growth and fallows, and water has been combined with base fattening to promote luminous efficiency and absorption of the leaves, increase nutrient accumulation and help restore the growth of trees and increase the fragmentation of buds。
4. The early stages of the cold tide, usually from december to january, are often damaged by low temperatures, resulting in the emergence of the citrus frost, resulting in the freezing of many fruits and affecting the quality of fruit. Therefore, water should be poured in a timely manner before the tide, which is very effective in reducing the frost damage。
These are the presentations on some of the cultivation of umbilical oranges and the concerns to be taken into account in watering them, in the hope that they will be of help and benefit。
