How to Improve Compacted Soil in Orchards? A Full Analysis of the Latest Methods
Orchards can basically be found in various parts of our country, and for many people, fruit is an indispensable food every day. Therefore, our country's fruit market is currently quite good. And when we grow fruit, the soil is very important. Many fruit growers find during planting that orchard soil often becomes compacted, so what should be done about orchard soil compaction? Below, the editor will give everyone a brief introduction. Let's take a look together!
1. Dig trenches between rows and deep plow
If you want to break up soil compaction, then digging trenches and deep plowing the soil is certainly indispensable. The growth of many fruit tree root systems can be said to be all-around, so if you do not dig between rows, it will cause relatively great harm to the fruit tree roots. Deep digging between rows can reduce damage to the roots. When deep plowing, be careful not to injure the main roots, although it will cause some damage to the absorbing roots. But it will not cause a major impact on the growth of the fruit trees. If a thick root is accidentally cut, then the wound should be smoothed to promote the growth of new roots.
2. Apply organic fertilizer in autumn
When fertilizing, pay attention to the application of chemical fertilizers. Wait until chemical fertilizers must be applied before applying them, and increase the application amount of organic fertilizer. Although chemical fertilizer is a key fertilizer for ensuring fruit tree yield. But if applied excessively, it can very easily cause soil compaction, and fruit trees are also prone to fertilizer damage. Therefore, after the fruit trees are harvested in autumn, apply sufficient decomposed farmyard manure in combination with digging trenches between rows and deep plowing. This improves the soil, breaks up compaction, and enhances the growth capacity of the fruit trees. Moreover, after the fruit is harvested, the roots of basically many fruit trees are in a period of vigorous growth, and fertilizing at this time can provide sufficient nutrition for the root system.
3. Growing grass in the orchard
Growing grass in the orchard mainly uses the roots of weeds to fix them in the topsoil of the soil. However, note that when growing grass, the root system of the weeds must not be too long, to prevent them from competing with the fruit trees for growth nutrients. This can provide good protection for the soil, improve soil structure, and increase the soil's water- and fertilizer-retention capacity. Pay attention to the variety of weeds, generally mainly legumes. The main roots of leguminous weeds are generally not very deep. Their growth capacity is also relatively strong, making them a relatively good weed variety for improving soil structure. However, also pay attention to their growth; do not let them grow too tall, otherwise it will cause a relatively great impact on the growth of the fruit on the lower part of the fruit trees.
4. Water reasonably
When watering, pay attention to choosing a good watering method. Do not use flood irrigation in the orchard; flood irrigation is the most likely to cause soil compaction. Because the impact force of the large amount of water will squeeze the air in the soil, resulting in insufficient oxygen in the soil. In addition, it will also hinder the rise of ground temperature, especially in spring, when the impact will be even greater. Moreover, flood irrigation will also destroy the granular structure in the soil, and once the granular structure is destroyed, it will naturally lead to soil compaction. So when watering, pay attention to mainly using small-drop drip irrigation to protect the soil.
