“三高”保高产:莲藕系多年生地下茎水生高等经济植物,具有喜大肥、高积温的生长特性。一高——“高肥力”。土层浅,土壤粪肥含量就高,藕池不漏水,也就不漏肥,大量施入的粪肥能够充分满足莲藕的生长。二高——“高积温”。莲藕栽培初期,气温低,浅水栽培水温易提高,促进莲藕早发芽生长;中期气温较高,加高水位,藕根水温比较适宜;后期气温逐步降低,水位也逐步降低,便于接受阳光,减少水温下降的幅度,延长莲藕的生长。三 “Three high ” Paul high yield: Lotus root perennial perennial aquatic higher economic plants, with hi fat, high temperature growth characteristics. A high - “high fertility ”. Soil shallow, soil manure content is high, lotus pond watertight, it does not leak fat, a large number of manure applied to fully meet the growth of the lotus root. Second High - “High Accumulated Temperature ”. In the early stage of cultivation, the temperature of the lotus root is low, the water temperature of the shallow water cultivation is easy to increase, which promotes the early germination and growth of the lotus root. In the middle period, the air temperature is higher and the water level is higher, and the root water temperature is more suitable. Decline, to extend the growth of lotus root. three
