低温水灌溉对花生植株生长动态的影响

摘要

In peanut production, irrigation with low temperature well water usually caused yield reduction.To solve this problem, we take the condition of rainproof shed and cement pool planting to study the effects of irrigation with low temperature water on plant growth of peanut.The results showed that the irrigation with low temperature water significantly reduced the peanut plant height, the main-stem and lateral stalk pitch, the total and effective branching, delayed the days of sprout leaves and reduced the number of young leaves.With the temperature of irrigation water decreased, the influence on the growth of seedlings got more significant.%本研究针对花生生产中采用低温井水灌溉常造成减产的实际问题，在防雨棚水泥池栽控水条件下，以鲁花11号花生品种为材料，系统研究了低温水灌溉对花生植株生长的影响。结果表明，低温水灌溉可显著降低花生株高，减少主侧茎茎节数、总分枝数和有效分枝数，延长新生叶片出叶时间、降低新生叶片数量。随灌溉水温的降低，对植株生长的影响越明显。
