How to do a good job in fertilizer and water management for orange trees? Detailed explanation of the technical points
The orange is a fruit belonging to the genus Citrus, and it has a relatively large planting area in China. When planting orange trees, for the sake of the oranges' yield and quality, fertilizer and water management is very important. Fertilizer and water management are the key measures for meeting 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 for 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 periods, then it cannot 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-flushing period or the flowering and fruiting period. Sufficient water must be maintained to allow orange trees to flower and bear fruit normally. However, water should not be excessive either. If there is too much water and waterlogging occurs in the soil, then the roots will rot due to lack of oxygen.
Therefore, we must strengthen water management and do a good job in 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 opened properly to avoid continuous rainy days causing waterlogging that damages the roots and leads to 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, fertilization should be based on the growth characteristics of young trees, such as fast growth speed, small growth amount, limited root distribution, and poor fertilizer tolerance. The fertilization principle is to apply more frequently but in small amounts. Apply fertilizer about twice in total before and after the spring shoots, mainly using manure water and urea, to promote root development of the orange trees.
Then after entering the fruiting stage, spring fertilizer is generally applied about twice. The first application should be made about half a month before the spring buds sprout, to ensure robust growth of the spring shoots. Then the second fertilization is 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 in orange trees, but it should not be excessive 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!
