摘要：

为了解滴灌模式对玉米生长的影响，以甜玉米（正甜68）为试验材料，采用大田试验研究不覆膜充分滴灌（T1）、膜下充分滴灌（T2）和膜下控墒滴灌（T3）3种模式对甜玉米生物量及分配、产量和水分利用效率的影响。结果表明：（1）不同滴灌模式对甜玉米生物量没有显著影响。T3处理甜玉米茎-植株和叶-植株异速生长指数均小于T1和T2处理；而T1处理根-植株异速生长指数小于T2和T3处理；（2）T2和T3处理甜玉米营养器官-生殖器官异速生长指数为1，呈等速生长关系，而T1处理营养器官-生殖器官异速生长指数小于1，呈异速生长关系；（3）T1处理甜玉米地下部分-地上部分异速生长指数小于T2和T3处理。这表明不同滴灌模式能改变甜玉米异速生长轨迹，覆膜滴灌可能促进甜玉米茎、叶、地上部分和生殖器官的生物量分配。与T1处理相比，在甜玉米产量差异不显著的前提下，T2和T3处理分别节水26%和44%，灌溉水利用效率分别提高0.65和1.43 kg·m^-3。可见，膜下控墒滴灌（土壤相对含水量下限为70%，上限为90%）是适用于元谋干热河谷甜玉米种植的高效节水灌溉模式。

Abstract:

To investigate the effects of irrigation modes on biomass,biomass allocation,corn yield and water use efficiency of sweet corn,a field experiment including full drip irrigation without plastic film (T1),full drip irrigation under plastic film (T2) and drip irrigation with limited soil moisture under plastic film (T3) was conducted. The results show that irrigation modes had no significant effects on the biomass of sweet corn,but affected the allometric scaling relationships between different organs. The scaling exponents of stem mass vs total plant mass and leaf mass vs total plant mass for T3 were lower than those for T2 and T1. The scaling exponents of root mass vs total plant mass for T1 were lower than those for T2 and T3. The vegetative organ were isometric with the reproductive organ for T2 and T3,indicating that the growth rate of reproductive organs was proportional to the growth rate of vegetative organs. The scaling exponents of vegetative organ vs. reproductive organ for T1 was lower than 1,indicating that the growth rate of reproductive organs scaled allometrically with the growth rate of vegetative organs. The scaling exponents of underground vs. aboveground biomass for T1 were lower than for T2 and T3. Drip irrigation under plastic film increased the allocation biomass toward stem,leaf, aboveground and reproductive organ compared to the other treatments. Under the equivalent production,T2 and T3 saved water by 26% and 44%,and improved water use efficiency by 0.65 and 1.43 kg·m^-3 compared to T1,respectively. Drip irrigation with limited soil moisture under plastic film (the lower limit of relative soil water content is 70%, the upper limit is 90%) is a water-saving and efficient irrigation mode of sweet corn in Yuanmou dry hot valley.

Key words: irrigation pattern, dry hot valley, biomass allocation, water use efficiency
