Description

Fertilization method to promote the cultivation of fibrous roots of rubber trees

technical field

The invention relates to a fertilization method, more particularly, to a fertilization method for promoting the cultivation of fibrous roots of rubber trees.

Background technique

Fertilization is an important measure for the fast growth and high yield of rubber trees. At present, fertilization is still mainly done by hand, which has high labor intensity, low efficiency and high cost. There are four main methods of fertilization.

One is to manually dig a circular ditch along the contour at the drip line of the rubber tree crown, and then artificially spread the fertilizer and then cover it with soil; the other is to dig a fertilization bed or pit between two trees along the digital connection direction, and then fertilize and cover Pressing green material, the above two methods are all done manually, with low efficiency, high cost, and high strength; the third is to use a single plow to ditch in the rubber tree industry, but the ditch depth is not enough, and the second ditch needs to be repeated after fertilization and coverage , destroying the cultivation of fibrous roots many times, which is not conducive to the absorption of nutrients by the rubber tree; the fourth is to use the excavator to dig deep trenches, then cover the fertilizer and press the green. Considering the factors of the weight and flexibility of the excavator, the second operation still relies on manual labor. The efficiency and cost indicators of fertilization, green pressing and backfill operations are still not obvious enough.

Contents of the invention

The present invention overcomes at least one defect described in the above-mentioned prior art, and provides a fertilization method for promoting the cultivation of fibrous roots of rubber trees. The fertilization method conforms to the growth law of rubber trees and is beneficial to the growth and development of fibrous roots of rubber trees.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the fertilization method that promotes rubber tree fibrous root cultivation is characterized in that, comprises the following steps:

S1: Ditching operation: Ditch the rubber tree between the rows, and the ditching position is 250cm~350cm away from the root of the tree;

S2: After step S1 is completed, fertilization operation is carried out, the scope of fertilization operation is radiated from the bottom of the ditch to the edge of the ditch body, and the thickness of fertilization is gradually reduced from the bottom of the ditch to the edge of the ditch body;

S3: After the step S2 is completed, the soil covering operation is carried out, and the surface of the ditch body is covered with soil after the fertilization operation, and the thickness of the soil covering is 8cm~11cm;

S4: After step S3 is completed, topdressing operation is carried out. The topdressing operation is carried out 3 to 4 months after the soil covering operation is completed. The scope of topdressing operation is radiated from the lowest point of the ditch body after the soil covering operation to the edge of the ditch body after the soil covering operation. Topdressing The thickness decreases from the lowest point of the ditch body to the edge of the ditch body;

S5: After step S4 is completed, perform soil covering operation: perform soil covering operation on the ditch body after the topdressing operation, and the thickness of the covering soil is 8cm-10cm.

This fertilization method includes four parts. Firstly, the ditching operation is carried out at a position 250cm~350cm away from the tree root. After the ditching operation is completed, the fertilization operation is carried out at the ditching position. The fertilization operation range is from the bottom of the ditch to the edge of the ditch body. The fertilized surface covers the surface of the ditch body, and the thickness of the fertilization gradually decreases from the bottom of the ditch to the edge of the ditch body, which can effectively reduce the volatilization of fertilizers. After the fertilization operation is completed, the soil covering operation is carried out. The soil covering operation completely covers the fertilizer spread on the ditch body, reduces the volatilization of fertilizer, and increases the utilization rate of fertilizer. 3 to 4 months after the fertilization and soil-covering operations are completed, the top-dressing operation is carried out. The operation method of the top-dressing operation is the same as that of the fertilization operation.

In one embodiment, the width of the groove body is 45 cm to 55 cm, and the value of the groove body depth is 40 cm to 50 cm.

The width of the ditch is designed to be 45cm~55cm, and the depth of the ditch is designed to be 40cm~50cm. This design can ensure that the ditch has sufficient volume, and at the same time, the depth of the ditch is designed to be 40cm~50cm to meet The requirements for the depth of the ditch after repeated topdressing and soil covering. When the width of the ditch remains unchanged and the depth of the ditch is 40 cm, the volatilization of fertilizer is relatively large due to the shallow depth, but it takes less time for the rubber plantation to fully absorb and utilize the fertilizer; when the width of the ditch remains unchanged, When the depth of the ditch was 50 cm, the volatilization of fertilizer was less due to the deeper depth, but it took longer for the rubber plantation to fully absorb and utilize the fertilizer.

Preferably, the groove width is 48cm-50cm, and the groove depth is 44cm-47cm. .

When the width of the ditch is 48cm-50cm and the depth is 44cm-47cm, on the premise of ensuring that the ditch has sufficient volume, it can also reduce the time it takes for the rubber plantation to absorb and utilize fertilizers as much as possible.

In one embodiment, the fertilization operation is carried out once a year, and the topdressing process is carried out 2-3 times a year.

The fertilization operation is carried out once a year, and then the ditch created by the fertilization operation is used for multiple topdressing and soil covering operations, avoiding the trouble of re-ditching every time topdressing, simplifying the complexity of the process, and facilitating the implementation of the process.

Compared with the prior art, the present invention can meet the requirements for fertilizers in the growth process of rubber forests, effectively promote the growth of rubber tree roots and growth through fertilization and topdressing, effectively improve the operation efficiency of fertilization and topdressing, and reduce operating costs and time.

Example 1:

The present invention provides the fertilization method that promotes rubber tree fibrous root cultivation, comprises the following steps

S1: Ditching operation: Ditching between 1 row of rubber trees, the location of the ditching is 250cm~350cm away from the root of the tree;

S2: After step S1 is completed, fertilization operation is carried out, the scope of fertilization operation is radiated from the ditch bottom 2 to the edge of the ditch body, and the fertilization thickness is gradually reduced from the ditch bottom 2 to the edge of the ditch body;

S3: After the step S2 is completed, the soil covering operation is carried out, and the surface 3 of the ditch body after the fertilization operation is covered with soil, and the thickness of the soil covering is 8cm-11cm;

S4: After step S3 is completed, topdressing operation is carried out. The topdressing operation is carried out 3 to 4 months after the soil covering operation is completed. The scope of topdressing operation is radiated from the lowest point of the ditch body after the soil covering operation to the edge of the ditch body after the soil covering operation. Topdressing The thickness decreases from the lowest point of the ditch body to the edge of the ditch body;

S5: After step S4 is completed, perform soil covering operation: perform soil covering operation on the ditch body after the topdressing operation, and the thickness of the covering soil is 8cm-10cm.

The fertilization method includes ditching operation, fertilization operation, soil covering operation, and topdressing operation. After the ditching operation is completed, the fertilization operation, soil covering operation, and topdressing operation are all carried out in the opened ditch, reducing and simplifying unnecessary processes. Improve process efficiency.

As shown in Figures 1 and 2, the ditching operation is performed at a position 250 cm to 350 cm away from the root of the rubber tree 1, preferably at a position 310 cm away from the root. After the ditching operation is completed, the fertilization operation is carried out at the ditching position, and the fertilization operation range is radiated from the lowest point of the ditch body to the edge of the ditch body.

As shown in FIG. 3 , the fertilized fertilizer surface 4 covers the surface of the ditch body, and the fertilization thickness gradually decreases from the ditch bottom 2 to the edge of the ditch body, which can effectively reduce the volatilization of fertilizers. After the fertilization operation is completed, the soil covering operation is carried out. The soil covering operation completely covers the fertilizer sprinkled on the ditch body, reduces the volatilization of the fertilizer, and increases the utilization rate of the fertilizer.

3 to 4 months after the fertilization and soil covering operations are completed, the topdressing operation is carried out. The operation method of the topdressing operation is the same as that of the fertilization operation. After the topdressing operation is completed, the soil covering operation is carried out again to prevent the fertilizer from volatilizing.

The topdressing operation is carried out two to three times a year to meet the growth needs of the rubber tree and promote the growth of the roots of the rubber tree.

In the covering operation, the thickness of the covering soil is about 8cm~10cm. The covering soil prevents the volatilization of fertilizers, promotes the absorption of fertilizers by rubber trees, and is beneficial to the growth of roots and hairs of rubber trees.

The width of the ditch is designed to be 45cm~55cm, and the depth of the ditch is designed to be 40cm~50cm, which can ensure that the ditch has enough volume to meet the volume requirements of fertilization, multiple topdressing, and soil covering.

On the premise that the volume of the ditch body is sufficient, the depth of the ditch body is too deep or too shallow, which is not conducive to the absorption of fertilizers. At the same time, if the width of the ditch is too wide, the root development of the rubber tree will be damaged, and if the width of the ditch is too narrow, it will not be conducive to the absorption of fertilizers by the rubber tree. The width of the ditch is 48cm~50cm, and the depth of the ditch is 44cm~47cm, which can ensure the development of rubber tree roots and the absorption of fertilizers by rubber trees when the ditch has sufficient volume.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here.
