玉米种子的载体带播种法初探

A PRELIMINARY STUDY ON METHOD OF SOWING IN CARRYING-AGENT-BELT IN MAIZE

本法即将玉米种子固定在载体带上和以小型设施送带到田间沟内覆土填埋。近年研究表明，载体带的不同入土放置形式，对玉米影响很大。在此基础上，本研究调查了载体带的四种入土放置形式（仰式、腹式侧式和自由式）对玉米出苗、性状、叶向和产量的影响，结果认为仰式较理想，在不影响出苗情况下，不但节约种子，减免间、定苗，而且通过调整种子胚向、固定种子似可调整植株叶向，达到玉米的“定向栽培”，从而加大密度，提高光能利用率，增加产量。

This method included laying seeds of maize on Carrying-Agent-Belt )CAB) and putting CAb into drill furrow with minor machine. The studies of it inthe last few years indicated that the laving ways of CAB had a great efforts onmaize. Based on it this study investigated the efforts of four laying ways of CAB (face upward, face downward. face side and random) on emergence ofseedlings, character, leaf -direction and field in maize. The results indicated that the laying way of face upward was satisfied. It could not only decrease seed quantity, eliminate discarding plant without influencing emergence of seedlings but also regulate leaf-direction through regulating embtyo-direction and fix seeds. It resulted in directional cultivation, thus increasing utilized coefficient of light energy and yield.
