Latest Key Technical Points for Fertilizer and Water Management of Orange Trees
The orange is a fruit belonging to the Citrus genus, and it has a relatively large planting area in our country. When planting orange trees, fertilizer and water management is very important for the yield and quality of the oranges. Fertilizer and water management is a key measure to meet the nutritional and water needs of oranges, so how should fertilizer and water management be carried out when planting orange trees? Below, the editor brings you the fertilizer and water management of orange trees, let's take a look!
1. Water management
When planting orange trees, water management is very important. In some places, the rainfall may be relatively high, but if it is evenly distributed with alternating dry and wet conditions, then it will not play a very good role in the growth of orange trees. This is because orange trees have a certain demand for water whether during the shoot emergence stage or the flowering and fruiting stage. Sufficient water must be maintained to allow the orange trees to flower and bear fruit normally. However, water should not be excessive either. If there is too much water and water accumulates in the soil, then the roots will rot due to lack of oxygen.
Therefore, we must strengthen water management and do a good job of drainage and irrigation for orange trees according to their water requirements. In spring, try to keep the soil moist. This is because spring is the period when orange trees sprout and bloom, and at this time there must be sufficient water to ensure the growth and development of the spring shoots and flower organs of the orange trees. At the same time, it can also effectively reduce the physiological fruit drop of orange trees after flowering. In the orange orchard, drainage ditches should be well opened to avoid continuous rainy days that lead to waterlogging of the roots and root rot.
2. Fertilization management
During the young tree stage of orange trees, it is the main stage for cultivating the tree canopy of orange trees. At this time, in order to achieve the goals of rapid growth, early fruiting, and high yield of orange trees. According to the growth characteristics of young trees, such as fast growth speed, not large growth amount, limited root distribution, and poor fertilizer tolerance, etc. The fertilization principle is to apply more frequently in small amounts. Apply fertilizer about two times in total before and after the spring shoots, mainly using manure water and urea, to promote rooting of the orange trees.
Then after entering the fruiting stage, spring fertilizer is generally applied about two times. The first application should be made about half a month before the spring buds sprout, to ensure vigorous growth of the spring shoots. Then the second fertilization should be carried out in March. It is mainly to supplement the nutrients consumed by flowering after the flowers fade, promote the spring shoots to turn green as early as possible, and ensure the normal development of young fruit. However, attention should be paid to the application of nitrogen fertilizer. Insufficient nitrogen fertilizer can easily lead to fruit drop of orange trees, but it should not be too much either. Too much can easily cause a large number of late spring shoots and summer shoots to sprout, which is instead detrimental to their growth.
The above is a brief introduction to the key points of fertilizer and water management for orange trees. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
