高要县活道公社严村大队,地处山区,地势較高。全大队山地面积8,200亩,其中成林的5,000亩,植被較好。双季水稻田面积945亩。絕大部分稻田分布于山坑谷底,田块狹小,土质为紅壤母质发育而成。由于受山阴影响,阳光不足,日照一般为6~9小时。气溫較低,早春暖得迟,冬季冷得早。加之地下水位高,常有地下冷泉水、鉄銹水涌出,土壤酸性大(PH值5~6),肥力低,造成过去低产落后田面积大。据調查,1957年平均亩产576斤。在1,100亩稻田中,有200亩年产300~400斤;400~500斤
Gaoyao County live Road commune Yancun brigade, is located in the mountains, higher ground. The entire group of 8,200 acres of mountainous area, of which 5,000 acres of forest, vegetation is better. Double season paddy field area 945 mus. The vast majority of paddy fields are distributed at the bottom of mountain pit, and the plots are small and the soil is developed from the parent material of red soil. Due to shan-yin, sunshine, sunlight is generally 6 to 9 hours. The temperature is low, early spring is warm, winter is cold early. In addition to the high groundwater level, there are often underground cold spring water, 鉄 rust water pouring, soil acidity (PH value of 5 to 6), low fertility, resulting in the past low yield lagging fields area. According to the survey, the average yield of 5757 kg in 1957. In 1,100 acres of rice fields, 200 acres with an annual output of 300 to 400 pounds; 400 to 500 pounds
