我省水稻的生产自然环境,是低纬高原。水稻生育中期,恰当雨季,气温不高,因而生育期较长;但在其生育前后期内,正当干季首尾,日照充足,可利用的积温不少。解放以来,由于水利条件的改善,新品种不断育成推广,施肥增加,水稻产量逐步有所提高。但中部原有高产区单产长期不稳,最高单产还停滞在一千三百斤左右,而北部及高寒山区,水稻单产更是低而不稳。
The production of rice in our province’s natural environment is the low latitude plateau. Mid-term rice growth, the right rainy season, the temperature is not high, so a longer period of growth; but before and after its birth, just during the dry season, adequate sunshine, accumulated useful temperature. Since the liberation, due to the improvement of water conservancy conditions, new breeds have been continuously popularized and popularized, fertilization increased, and the output of rice gradually increased. However, in the central part of the country, the yield of the high-yielding areas in the central region was long-term unstable with the maximum yield stagnating at about 1,300 kilograms. In the northern and alpine regions, the yield of rice was even lower and unstable.
