fcis-32182	Zhang, Long; Hou, Zhesheng	Design and Testing of a Soil Inversion and Mulching Machine	2025	5	.pdf	application/pdf	3155	119	47	Soil turning quality: Measure the depth of rotary tillage at 30 points (qualified for 10-20cm), screen the broken soil rate of 1m ² tillage layer (proportion of particle size ≤10mm); Film quality: Measure the flatness, damage rate, longitudinal tensile rate, and centerline deviation of the 30m daylighting surface; Quality of covering soil: Measure the width (8-12cm qualified), thickness (2-3cm qualified), and degree of soil leakage at the edge of the membrane; Homework efficiency: Measure 3 sets of 0.2hm ² homework time and calculate the average productivity. A large amount of water is lost due to evaporation and leakage, and long-term use can damage the soil structure, leading to soil compaction, decreased air permeability, and affecting the development of vegetable roots[3].	cache/fcis-32182.pdf	txt/fcis-32182.txt
