摘要/Abstract

摘要： 农田防护林是甘肃河西走廊绿洲农田生态系统的重要组成部分，对维持农业生产和生态平衡具有重要作用.本文对防护林保护下的玉米灌浆期光合生理生态特性及产量变化进行了研究.结果表明：防护林东西相等距离处，东面玉米所截获的光合有效辐射量（PAR）始终高于西面；西面20 m以内玉米受林带（防护林高度为10 m）遮光较为严重，其净光合速率（P_n）较低；林带东面15 m范围内的玉米P_n高于西面.总体上，防护林造成的玉米减产发生在林带东面10 m及西面15～20 m范围内，其他位置的玉米产量不受影响或增产.

Abstract: Farmland shelterbelt is a main component of oasis agro-ecosystem in the Hexi corridor of Gansu Province, which plays an important role in maintaining local agricultural production and ecological balance. This paper studied the photosynthetic characteristics of maize at its grain-filling stage and the grain yield of maize under the protection of the shelterbelt. The results showed that at the same distances east and west of the shelterbelt, maize plants at the east side always intercepted more photosynthetic active radiation (PAR) than those at the west side. Within 20 m from the west side of the shelterbelt, the net photosynthetic rate (Pn) of maize plants was lower because of the serious shading by trees; and within 15 m from the west side, the Pn was lower than that from the east side. The grain yield of maize was decreased within 10 m from the east and 15〖KG-*2〗-〖KG-*7〗20 m from the west side, but increased or not affected in other locations.

Key words: sloping farmland, hedgerow, soil infiltration, common empirical model, purple soil area.
