摘要
对豫西旱农区两种轮作方式下旱地的耕作保墒技术进行了3年研究。着重讨论了二年三熟制下晒旱地深耕、深耕加秸秆覆盖以及深耕配施有机肥的蓄水保墒效果;一年二熟制下中耕效果与土壤质地和土壤含水量的关系以及中耕的适宜范围、多次中耕对保墒的迭加作用等问题,为完善旱农区的耕作保墒技术提供了科学依据。
The moisture conservation techniques for
rainfed land tillages werestudied under two kinds of rotational patterns in the rainfed
agricultural region in thewest part of Henan Province for three years. This paper puts more
stress on the discus-sion about the effects of water storage and moisture comservation by
sunning rainfedlands with subsoiling,subsoiling with stubble mulching and subsoiling matched
with or-ganic fertilizer added in the case of three crop two years'system,and relations of
hoeingeffects upon soil texture and soil water contents as vvell as the problems of
suitablerange of hoeing and overlapping effects of more hoeings upon moisture conservation
inthe case of two crops a year system thereby to provide the scientific bases for the
im-provement of moisture conservation techniques by tillages.
