ABSTRACT

This study investigated the effects of two different chemical products applied to the soil to on some mechanical properties of greenhouse cover materials produced by CO-EX techology with HALS UV and NIQ UV additives over a period of 12 months. The effects of chemical treatments on the covering materials were investigated in fourteen low tunnels under natural weathering conditions during their useful life. Also, the effects of sulphur products on the pH and electrical conductivity (EC) of the soil were investigated. Initial impact resistance of HALS UV and NIQ UV added PE films were determined as 685.0 and 811.7 g, respectively. Impact resistances of HALS UV and NIQ UV added PE films in bentonite sulphur applications decreased by 48.1% and 33.8%, whereas in elemental sulphur applications decreased by 62.0% and 51.6% after 12 months, respectively. Soil pH was reduced by all sulphur treatments in compared to the initial value.

摘要

本研究在 12 个月内调查了两种不同的化学产品应用于土壤对 CO-EX 技术使用 HALS UV 和 NIQ UV 添加剂生产的温室覆盖材料的某些机械性能的影响。在其使用寿命期间，在自然风化条件下，在 14 个低隧道中研究了化学处理对覆盖材料的影响。此外，还研究了硫产物对土壤 pH 值和电导率 (EC) 的影响。HALS UV 和 NIQ UV 添加的 PE 薄膜的初始抗冲击性分别确定为 685.0 和 811.7 g。HALS UV 和 NIQ UV 添加 PE 薄膜在膨润土硫应用中的抗冲击性在 12 个月后分别下降了 48.1% 和 33.8%，而在元素硫应用中分别下降了 62.0% 和 51.6%。
