东北雨养区黑色地膜和种植密度对玉米田间地温和产量的影响

摘要/Abstract

摘要：

在不同颜色地膜覆盖和种植密度条件下地温和作物产量将发生改变，为了研究其变化规律，2016年在沈阳农业大学水利学院试验场开展了玉米覆膜种植田间试验，设置了3种种植方式（裸地、透明地膜和黑色地膜覆盖）和3个种植密度（60000、75000和90000株·hm^-2）的田间试验，对玉米田间地温和产量进行了对比研究。结果表明：不同处理下田间0～25 cm深度平均地温的日变化呈现正态分布规律，总体上，透明地膜地温高于黑色地膜和裸地，低密度处理地温高于高密度处理；裸地种植条件下，玉米产量随密度的提高先增加后减小，覆膜处理下产量随着种植密度的增加而增加；黑膜处理下的玉米产量高于透明地膜和裸地，黑膜覆盖处理、密度为90000株·h^-2的组合产量达到最大，为14264.6 kg·hm^-2；产量与抽穗期的地温相关性最大，且表现为负相关关系。本文研究结果对提高东北雨养区玉米产量具有指导意义。

Abstract: Maize yield and soil temperature will be changed in different color film mulchings and plant densities. In recent years, maize yield is increasing mainly due to using of plastic mulching and high tolerant maize hybrids. However, the understanding of effects of plastic mulching and plant density on soil temperature and maize yield still need improvement. This study aimed to evaluate the effects of plastic film mulching and plant density on maize yield and soil temperature. The field experiment was conducted in main plots under three types of mulching (nonmulching, black plastic film mulching and transparent plastic film mulching), which were divided into three subplots with different plant densities (60000, 75000 and 90000 plants·hm^-2) at Shenyang Agricultural University, Shen-yang, Northeast China, during maize growing season of 2016. The daily variation of 0-25 cm depth average temperature of different treatments all showed a normal distribution trend. Average temperature of 0-25 cm soil depth was higher under transparent film treatments than under black film and nonmulching treatments, and increased with the decrease of plant density. Combination of black film mulching and the density of 9000 plants·hm^-2 reached a maximum yield of 14264.6 kg·hm^-2. The soil temperature in heading stage had negative influence on maize yield. These results can help smallholders to choose reasonable agricultural techniques to improve maize yield in rainfed area of Northeast China.
