Abstract
The invention provides the long-acting mulch film of the special resistance to oxidation of a kind of sugarcane, be made up of following raw material: polyethylene raw material polyethylene LLDPE? 7042:95-99%, oxidation inhibitor: 0.1-2%, UV light absorber: 0.01-1%, hindered amine as light stabilizer: 0.05-5% and whiteruss or vegetables oil 0.01-0.05%; Owing to adding anti-oxidant, the auxiliary agent such as uvioresistant and hindered amine as light stabilizer in mulch film blown film raw material, effectively can reduce the generation of free radical in mulch film, suppress the too fast oxidative degradation of mulch film, the oxidation resistent susceptibility of the mulch film of production is primarily of the common Coordinated Play of antioxidant, uvioresistant and hindered amine as light stabilizer.In mulch film production building-up process, Heating temperature lower than 180 DEG C, should prevent antioxidant component pyrolytic decomposition, and the thickness of mulch film ensures that Sugarcane Seedlings mulch film can be emerged by rupture of membranes smoothly.
Description
Technical field
The present invention relates to plastic material and water-saving agricultural technology field, especially a kind of resistance to oxidation, the long-acting mulch film of the special resistance to oxidation of radiation-resistant sugarcane.
Background technology
Along with Global warming, the increase of extreme freakish weather frequency, Sugarcane planting area seasonal drought becomes normality, and within 2009 to 2012, the rainfall of Yunnan Sugarcane Area anniversary is than 2000 young 30%-50%.Yunnan Province's sugarcane district drought resisting has become the work of annual.Mulch film is the drought resisting means of agricultural production of a kind of water conservation insulation, and sugarcane district of current sugarcane plastic-film mulching cultivation Yunnan Province pushes open comprehensively, serves obvious the effect of increasing income.But due to the crop (ripening stage 300-400 days) that sugarcane is a kind of growth cycle length, water consumption consumption is fertile, when arid continues aggravation, needs anniversary drought-resistant water-preserving, just can guarantee that sugarcane stable yields is increased production.Therefore need a kind of mulch film that can cover for a long time on producing, and coordinate rational film-mulching technique, reduce the effect that soil water evaporation plays anniversary drought-resistant water-preserving, guarantee that sugarcane is given stable high yields irrespective of drought or water logging.
The long-lived film sold in the market, by adding long-lived master batch in blown film process, improves the wearing quality of film, but is monopolized by developed country due to technology, and market value is higher.Long-lived film is mainly used in the canopy film of facility cultivation, such as remunerative crops such as anti-season fruit, vegetables, flowers.Because cost is high, the general economic crops growing cycle is short, and the long-lived mulch film for covered ground is not very general.Sugarcane is as a kind of crop of growth cycle length, and a kind of long-acting type mulch film that can meet the sugarcane production cycle plays obvious effect to sugarcane combating drought and raising yields.
Summary of the invention
The invention provides the long-acting mulch film of the special resistance to oxidation of a kind of sugarcane, owing to adding anti-oxidant, the auxiliary agent such as uvioresistant and hindered amine as light stabilizer in mulch film blown film raw material, effectively can reduce the generation of free radical in mulch film, suppress the too fast oxidative degradation of mulch film, the oxidation resistent susceptibility of the mulch film of production is primarily of the common Coordinated Play of antioxidant, uvioresistant and hindered amine as light stabilizer.In mulch film production building-up process, Heating temperature lower than 180 DEG C, should prevent antioxidant component pyrolytic decomposition; The thickness of mulch film ensures that Sugarcane Seedlings mulch film can be emerged by rupture of membranes smoothly.
