我县毛沟公社拱桥大队,位于武陵山区,四面环山,562亩水田中有近300亩分布在海拔430米的狭窄山沟里,另有200多亩散落在海拔500—600米的山腰,旱土640亩,夹杂在岩石中间。由于自然条件不好,解放前只种一季中稻,单产200—300斤。解放后推广双季稻,单产提高到1,000斤左右。1972年起,进行稻稻麦三熟栽培试验,1976年150亩三熟田,平均亩产小麦473斤,早稻842斤,晚稻687斤,三熟合计亩产2,002斤。他们的栽培措施是:一、选用适合山区的夏种这里日照短,气温低,沟深水凉,雾重多湿,病虫发生次数多。小麦赤霉病和水稻稻瘟病是两大毁灭性病害。针对这一情况,他们从品比试验中选用耐寒抗病,适应性强的“苏克菲”
Ward commune arch bridge brigade, located in Wuling Mountain, surrounded by mountains, 562 acres of paddy fields in nearly 300 acres distributed in a narrow ravine 430 meters above sea level, and another 200 acres scattered in the 500-600 meters above sea level mountainside, drought 640 acres of soil, mixed in the middle of the rock. Due to poor natural conditions, only a quarter of the rice before liberation, yield 200-300 pounds. After the liberation of promoting double cropping rice, yield increased to about 1,000 pounds. Since 1972, rice and rice cultivation practices three trials, 1976 150 acres of three fields, an average of 473 kg of wheat per mu, 842 kg of early rice, late rice 687 pounds, three acres of total yield 2,002 pounds. Their cultivation measures are: First, the selection of summer species suitable for mountain here short sunshine, low temperature, deep ditch water cool, heavy fog and wet, pests and more times. Wheat scab and rice blast are two devastating diseases. In response to this situation, they selected from the analogy test cold-resistant disease, adaptable “Supaye”
