| Abstract:The mulch paper was prepared by adding a small amount of softwood chemical pulp and chemical additives into self-made mechanical bamboo pulp， and it was applied in actual crop growth. The results showed that when the beating degree of mechanical bamboo pulp was 40 °SR， the mass ratio of mechanical bamboo pulp to softwood pulp was 80∶20， the dry tensile strength of 100 g/m2 mulch paper was 1.52 kN/m， and the tearing degree was 650 mN when 10% PVA fiber， 1.5% starch and 1.5% CNF were added into the pulp. On this basis， adding 1.0% PAE and 0.15% AKD， the wet tensile strength， Cobb value and water contact angle of the paper were 0.74 kN/m， 27.7 g/m2 and 112.95°， respectively. The paper produced according to this formula could promote the growth of pepper seedlings and sweet potato vines， and had good weed control effect and good degradability. |
