Introduction

Biodegradable mulches have been used in agriculture and horticulture around the world for many years: They can improve crop production by Long-term conditions that help increase yields and improve crop quality, such as: ---Suppress the growth of weeds; ---Significantly reduce the consumption of water and other resources; ---Control soil temperature; ---Reduce the leaching of mineral elements and other fertilizers; ---Reduce soil compaction; ---Protect crops from soil: Biodegradable mulch is designed so that it does not need to be recycled from the soil after its intended use period: Therefore, farmers no longer need to Biodegradable mulch film is recovered from the field after the crop is harvested for disposal or recycling: Farmers simply turn it over along with plant residues to blend into the soil: This document sets out the standard specifications required for biodegradable mulches used in agriculture and horticulture: It is suitable for describing the materials used in the manufacture of mulch The characteristics of plastic materials and mulch films themselves, such as biodegradation, adverse effects on terrestrial organisms and composition control: Plastic agricultural and gardening mulch with soil bio Degradable materials biodegradability, ecotoxicity and Requirements and test methods for ingredient control

1 Scope

This document applies to biodegradable plastic materials used in the production of mulches or prepared for use as agricultural and horticultural mulches: This document specifies test methods and evaluation criteria by discussing the following characteristics: a) Ingredient control; b) biodegradable; c) Negative effects on terrestrial organisms: Note: This document is used to evaluate other soil-degradable plastic products that are not eligible for mulch film, such as drip irrigation tapes, hanging vine ropes, clips and nursery bowls:
