红者下翻藤能增产,不仅在试验研究邮门已经肯定了,而且在我省红苕主要产区,如郧县、长阳、求风及枣阳等县已在大面积上推广应用,增产效果显著。据1965年在郧阳、郧西、均县及光化等县16个生产队的调查,19块(12.18亩)红苕,不翻藤的平均由产3366.7斤,此翻藤的每亩多收594.2斤,增产21.4%增产幅度为1.7—72%。 为什么红苕不翻藤能够增产呢?这是因为: 第一,红苕翻藤不可避免地要拉断一些藤叶。据调查,红苕翻一次藤,每亩要损坏藤叶30—50斤。同时,翻藤后,藤叶翻转正叠,不仪容易造成叶子发黄,落叶、死藤增加,而且翻转的藤叶需要几天才能复原,这都影响和降低了藤叶制造养分的能力。不翻藤的,藤叶既没有损伤,也未翻转,保证了藤叶的正常生长和光合作用的进行,因此,红苕不翻藤比翻藤增产。 Under the red turnovers to increase production, not only in the post-mortem study has been affirmed, but also in the main producing areas such as Yunxian, such as Yun County, Changyang, seeking wind and Zaoyang counties have been popularized in a large area to promote production Significant. According to a survey conducted by 16 production teams in Yunyang, Yunxi, Juxian and Guanghua counties in 1965, 19 (12.18 mu) red crabs were found, with an average yield of 3366.7 jin 594.2 pounds, an increase of 21.4% increase of 1.7-72%. Why is it not to turn red razor to increase production? This is because: First, turning red rattan will inevitably pull off some of the leaves. According to the survey, red croquet over a vine, vine damage to 30-50 pounds per mu. At the same time, after the vine was turned over, the vine leaves turned upside down. Not easy to cause yellow leaves, deciduous leaves and dead leaves, and the tilted vine leaves took several days to recover. All this affected and reduced the ability of making vine leaves. Not to turn the vine, the vine leaves neither damage nor flip, to ensure the normal growth of vine leaves and photosynthesis, therefore, red cinnamon does not turn over rattan vines yield.
