Fertilizer application method for promoting cultivation of fibrous roots of rubber trees

Abstract

The invention relates to a fertilizer application method, particularly to a fertilizer application method for promoting the cultivation of the fibrous roots of rubber trees. The fertilizer applicationmethod comprises: S1, ditching, wherein ditches are dug between rubber tree rows; S2, after completing the ditching, carrying out fertilizer application, wherein the fertilizer application is performed from the ditch bottom to the ditch edge, and the fertilizer application thickness is gradually decreased from the ditch bottom to the ditch edge; S3, after completing the step S2, covering with soil, wherein the ditch surface is covered with soil after the fertilizer application; S4, after completing the step S3, carrying out top dressing, wherein the top dressing is performed at 3-4 months after the soil covering is completed, the top dressing is performed from the lowest point of the ditch to the ditch edge after the soil covering operation, and the top dressing thickness is gradually decreased from the lowest point of the ditch to the ditch edge; and S5, after completing the step S4, covering with soil, wherein the ditch is covered with soil after the top dressing. According to the present invention, the fertilizer application mode meets the rubber tree growth law, and the growth and development of the fibrous root of the rubber tree can be easily achieved.

Description

technical field [0001] 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 [0002] 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. [0003] 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 ditc...

[0003] 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 compaction and backfill operations are still not obvious enough
