大约在五年前由日本东北大学(仙台)农学部试验而成的深水栽培,正被日本稻农所采用,同时还形成了二小流派的演变。 1.运用普通小苗带土插秧机插秧,然后待大田苗数达有效穗数的70%左右时进行满水灌为株高的1/4,直至出穗前4—5天才进行浅水、干干湿湿的管理。 2.运用营养孔穴育苗插秧机插秧三天后就进行灌满水至最上全展叶的叶耳处,淹至幼穗分化期止,然后再浅水管理,深层施穗肥。
Deep-water cultivation, experimentally conducted by the Faculty of Agriculture of Tohoku University (Sendai, Japan) about five years ago, is being adopted by Japanese rice farmers and at the same time has led to the evolution of two smaller genres. 1. The use of ordinary seedlings with soil transplanter transplanting, and then until the number of field sprouts seedlings about 70% of the effective spike when full of irrigation for the plant height of 1/4, 4-5 days before the earliest to shallow water, dry Wet management. 2. The use of nutrition hole seedling transplanter Transplanting three days after filling the water to the top of all leaves of the ear, flooded until the panicle differentiation period, and then shallow water management, deep panicle fertilization.
