闽西北山区是我省主要产粮区,由于地形复杂,气候差异大,有相当部分的地区其光热资源属于两季不足,一季有余,种植双季稻,往往受到秋寒的威胁而使晚稻减产,种植单季稻则又不能充分利用土地和光热资源;有些望天田由于秋旱也只能种植一季。为了充分利用光热和土地资源。在不适宜种植双季稻的地区,发展稻杂两熟,走水旱轮作的道路。我们在1979～1980年改制研究的基础上,于1984～1985年继续开展了本项试验,为山区产业结构调整,实行农牧结合,培肥地力,提高产量,提供科学依据。
The mountainous area in northwestern Fujian is the main grain-producing area in our province. Due to the complex terrain and large climatic differences, a considerable part of its light and heat resources are deficient in two seasons, with more than one season. Double-cropping rice is often threatened by autumn fall, Cut production, planting single-season rice is not able to make full use of land and light and heat resources; some Tiantian Tian due to autumn drought can only grow a season. In order to make full use of solar heat and land resources. In areas unsuitable for planting double cropping rice, it is necessary to develop a two-crop hybrid rice and take the road to dry rotation. Based on the restructuring study from 1979 to 1980, we conducted this experiment from 1984 to 1985 to provide a scientific basis for the adjustment of the industrial structure in mountainous areas, implementing the combination of agriculture and animal husbandry, fertilizing the land, and increasing the output.
