What are the latest fertilization methods for mulberry trees?
Mulberry is a relatively common fruit in our country, and its planting area is also quite large. When we plant mulberry trees, their management work is very important. This includes various basic management tasks such as pruning, watering, and fertilizing. Among them, when we fertilize mulberry, there are several different fertilization forms. So what exactly are they? Below, the editor will give you a brief introduction. Let's take a look together!
1. Root characteristics of mulberry trees
When fertilizing mulberry trees, we should pay attention to allowing the fertilizer to reach the soil layer where the mulberry tree roots are most widely distributed, so as to promote root absorption of the fertilizer. The root part of the mulberry tree is affected by factors such as tree age, planting density, planted variety, and soil type. Therefore, the fertilization range should be determined according to these factors. For example, if it is a short-trunk densely planted mulberry orchard, then the mulberry tree roots are generally distributed in the 40cm soil layer, and deep application is not needed. The fertilization forms are divided into the following three types.
2. Fertilization forms
1. Hole application method
The first fertilization form for mulberry trees is hole application. When applying by holes, first dig the fertilization holes at a position about 30cm from the trunk between the rows of mulberry trees, and then fertilize. The fertilizers are mainly chemical fertilizers and accompanying farmyard manure. These fertilizers are not large in volume, so the depth of the fertilization holes should be kept at about 20cm, and the length and width should be controlled at about 32cm. If it is a relatively large-volume fertilizer such as stable manure or composted manure, then the fertilization holes can be appropriately enlarged. Young mulberry trees should not be fertilized too much, so the fertilization holes can be smaller and shallower. After fertilization, cover with soil in time to improve fertilizer efficiency.
2. Trench application method
Trench application is to dig a fertilization trench between the rows of mulberry trees, usually suitable for large densely planted mulberry orchards. If the planting is relatively dense, then digging a trench directly in the middle of the rows for fertilization is sufficient. If the planting is relatively sparse, then a trench should also be dug on one side about 30cm from the trunk. The depth and width of the fertilization trench should also be controlled according to the type and amount of fertilizer applied. It is usually kept at about 25cm. When digging the trench, be careful to avoid damaging the roots as much as possible, so as not to affect the normal growth of mulberry. The trench application method is suitable for applying large-volume farmyard manure, and attention should also be paid to covering with soil after fertilization.
3. Broadcast application method
Broadcast application of mulberry is to directly and evenly scatter the fertilizer over the mulberry planting soil. Then, through work such as intertillage and loosening the soil, the fertilizer is turned into the soil. The suitable time for broadcast application should generally be in winter and summer, combined with application during winter plowing and summer pruning. The fertilizers that can be used include large-volume organic fertilizer, as well as substances that neutralize soil acidity and alkalinity, and so on. It is suitable for use in short-trunk densely planted mulberry orchards.
The above is a brief introduction to the fertilization forms and root characteristics of mulberry trees. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
