Paddy Eco-characteristics and High Yield Technology in Enshi Mountain Areas

Owing to the effect of topography, morphology and climate, the paddy ecosystem of Enshi mountain areas has significant mountainous characteristics. The climate of paddy fields shows a law of obvious vertical distribution. Whats more, the paddy ecosystem is complex in soil type, excessive in pests and diseases (especially, blast is distributed widely and its harm is serious), frequent in low temperature damage, low in intensive degree and difficult in tillage management. According to these characters, some technical measures were advanced to gain high yield and stable production of rice in Enshi mountain areas. First, the producer should choose varieties with anti- disease (mainly blast), hardy (cool late and autumn winds) and high-yield and do rational distribution with them. Second, we should take a series of steps to suit the needs of local conditions, including dry raising and thin planting, thrown dry rice nursery, semiarid cropping, rational rotation, scientific control of fertilizer and water and so on. Third, farmers should control diseases and insects comprehensively.
