Design of natural rubber precision ditch fertilization machine

Abstract

Abstract. According to the natural rubber deep fertilization ditch depth of 10~30cm between the width of 30~40cm between the requirements,we developed a fine ditch fertilizing machine. This paper introduces its structure and principle in detail. The machine uses a hoof-shaped furrow structure and centrifugal fertilizer structure. The machine is simple and easy to maintain. After testing, the machine can open the groove width of 20cm deep 35cm width.The machine fertilizer uniformity up to 90%.The machine productivity reached 1.3 hm 2 / h. The machine which meets the requirements of rubber tree fertilization has stable performance. At the same time, the machine can be the human's workload.

Towards Precision Fertilization: Multi-Strategy Grey Wolf Optimizer Based Model Evaluation and Yield Estimation

“…The ecosystem formed by "crop-soil-fertilizer" seems to continue indefinitely, but in each cycle, there is more or less natural loss, which needs to be replenished and controlled by human factors to continue the cycle [1][2][3][4][5][6]. Since its introduction in the 1980s, precision fertilization has been a significant constraint on balancing the contradiction between land resources, ecology, and population growth and a key technology for maintaining sustainable development [7][8][9][10][11]. Precision fertilization is based on soil testing, and field application trials and a comprehensive grasp of crop fertilization patterns, soil supply properties, and fertilizer effects are the primary means to ensure scientific fertilizer with yield increase, improve product quality, and food security while reducing environmental pollution and soil friendliness [12][13][14].…”

“…The growth of output depends on inputs, and crops need "food" to satisfy their growth. Plants need chemical elements, water, and carbon dioxide to synthesize organic matter under photosynthesis in sunlight, and fertilizers are essential "food" for crops [9][10][11][12][13][14][15]. The roots of crop growth are in the soil, and 60-70% of plant nutrients are absorbed from the soil [16][17][18][19][20][21][22].…”
