早稻长秧龄旱育高产栽培技术研究

THE RESEARCH ON THE CULTIVATION TECHNIQUES TO DRILY RAISE SEEDLINGS DURING THE LONG TIME OF SEEDLINGS GROWTH AND GET HIGH YIELD OF EARLY SEASON RICE

本文研究了旱育方式试验，处理间增产幅度，长秧龄旱育高产栽培具有特性。1、秧苗早发，2、生育进程表现为缓，快，缓，3、宽行窄株，适当密植，4、早发早控争粒多。主要栽培技术：1、稀播长秧旱育方法，2、大田移栽管理技术。本项研究不仅具有低耗栽培的优势。

This thesis is on the experiment on the dry raising method of rice seedlings and on the scttling of the amount of interval increase in prdduction. One of them has come up to an extremely notable standard and the other a notable standard.The cultivation characteristics are: 1. The rice seedlings sprout early. 2. The growing process is firstly slow, then fast and at Last slow. 3. The row spacing is wide and the individual spacing is narrow. The close planting is rational. 4. The sprouting and developing and controlled growlng is early. The grains are many.The main cultivation techniques are: 1. the methods of sparse sowing and dry raising of rice seedlings during the long time of their growth; 2. the management techniques of the transplanting of rice seedlings in the fields.This research has not only the superiority of low consumption but also the importance in the cultivation.
