摘要
以草帘为对照,研究了4种无纺布的保温效果及对辣椒生长和发育的影响。结果表明,500 g/m2的无纺布的保温效果最好,150(加膜)、200、250 g/m2的无纺布的保温效果也都优于草帘;覆盖500 g/m2的无纺布的辣椒生长速度最快、开花结果早、前期产量也最高,覆盖150(加膜)、200、250 g/m2的无纺布的辣椒生长发育和前期产量也都优于草帘。综合考虑保温效果、生产成本及操作方便,可以用200、250 g/m2的无纺布替代草帘,进行大棚冬春反季节辣椒生产。
Taking the grass curtain as the check covering material,the effects of four kinds of non-woven fabric on maintaining temperature and the growth of pepper were studied..The results showed that the non-woven fabric of 500 g/m2 had the best effect in maintaining temperature,the non-woven fabric of 150 g/m2(with film),200 g/m2 and 250 g/m2 had better effect than the grass curtain in maintaining temperature.The pepper covered by the non-woven fabric of 500 g/m2 had the fastest growth rate and higher yield at earlier stage,and its flowering and fruiting time went ahead too.The pepper covered by the non-woven fabric of 150 g/m2(with film),200 g/m2 and 250 g/m2 had better growth and development as well as higher early-yield than that covered by the grass curtain.Comprehensively considering maintaining temperature,production cost and conveniency of operation,the non-woven fabric of 200 g/m2 or 250 g/m2 can be used to replace the grass curtain in winter-spring anti-season pepper production under plastic greenhouse.
