残膜对棉花生长发育及产量的影响
Effects of Remnant Plastic Film in Soil on Growth and Yield of Cotton
摘要
Abstract
A series of tests consisting of micro－ plot, pot－ simulation and check－ up in situ has been conducted to assess impacts of residual plastic film in soil on cotton germination and growth. It has been discovered that quantities of remnant plastic film in soil was negatively related to rate of cotton germination and quantities of harvest plants (r=－ 0.737, r = － 0.740), respectively, showing that reductions of by 9.9％ — 19.1％ , 7.3％ — 16.5％ for rate of young seedling and harvest plants than that in soil without polluted remnant plastic film. The remnant plastic film resulted in reductions of cotton bolls by 0.8— 1.0 per 100, and of yield of cotton by 7.3％ — 21.6％ , respectively. It was also found that the angle of remnant plastic film against the polluted soil surface exhibited different degrees of risk to growth and development of cotton with an order of 180° > 30 ° > 60 ° > 90° .关键词
