Fertilization is one of the important management measures for fast-growing and high-yield rubber trees. Proper fertilization should be based on the needs of the rubber tree itself, soil properties, and fertilizer characteristics. To understand the characteristics and requirements of rubber trees, use the NPK fertilizer production process to target ingredients, and produce compound fertilizers suitable for the growth of rubber trees, in order to obtain the maximum economic benefits.
Characteristics of rubber tree growth
Rubber tree is a perennial tropical rainforest tree species of Euphorbiaceae, which can absorb nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and trace elements from the soil. If any of these elements is not enough to supply the growth and production demand of rubber trees, it will obviously affect the growth of rubber trees and the yield and quality of rubber.
Consequences of insufficient fertilizer supply for rubber trees
1. If the nitrogen supply is insufficient, the rubber leaves will be thin and small, the leaves will turn green, the branches and poles will be thin and short, the number of canopy will be small, the canopy distance will be short, the crown will be small, the recovery speed of regeneration skin will be slowed down obviously, and the front of the leaves will turn yellow.
2. When the supply of potassium is insufficient, the rubber leaves turn green and yellow.
3. When the supply of phosphorus is insufficient, the growth of rubber trees will be obviously inhibited, the activity of cambium will be blocked, and the growth of stem circumference will slow down.
Fertilizer supply for rubber trees
The fertilizer of rubber tree should contain not only three elements of nitrogen, phosphorus and potassium, but also many nutrients such as calcium, magnesium, sulfur and iron, as well as a large number of organic matter. These substances will form humus under the action of microorganisms, which can reduce nutrient loss and improve soil fertility. Therefore, through the fertilizer granulator machine to combine a variety of nutrients, it can meet the needs of rubber trees.
The results showed that the biomass and growth of rubber tree increased significantly, the plant height and chlorophyll content of rubber tree increased significantly, and the effect was better than that of single fertilizer. According to the combination of different raw materials, double roller fertilizer granulator, disc granulator, organic fertilizer granulator and other equipment are selected to process rubber tree fertilizer.
