本省近几年来大、小麦(以及裸麦)苗期发生黄苗、矮苗,轻则植株生长不良,不能抽穗或穗而不实;重则苗期陆续枯死,影响春粮的平衡高产。根据三年来调查、观察,主要由于冬旱春冷的气候影响,麦类黄苗、矮苗的发生发展也蔓延扩大;发生的征状、类别和致病因素也较为繁多、复杂,成为当前春粮生产上迫切需要从速解决的问题之一。因此必须发动群众,开展调查研究,探明黄苗、矮苗发生发展的规律,查明产生黄苗的原因,通过科学实验,提供防治的有效措施。现将我们近二年来开展调查研究和总结群众防治经验的初步情况报导于下,以供参考。
The province in recent years, large, wheat (as well as rye) seedling occurs yellow seedlings, short seedlings, ranging from poor plant growth, can not be heading or ear and false; heavy seedling died one after another, affecting the balance of spring grain yield. According to the survey and observation over the past three years, the occurrence and development of wheat yellow seedlings and short seedlings also spread and expanded mainly due to the winter and spring cold weather; the symptoms, categories and risk factors of the wheat are also more numerous and complicated, becoming the current spring One of the urgent problems that need to be solved urgently in food production. Therefore, it is necessary to mobilize the masses to carry out investigation and study to find out the law of development of yellow seedlings and young seedlings, find out the reasons for the emergence of yellow seedlings, and provide effective measures for prevention and treatment through scientific experiments. Now we have carried out the investigation and research in the past two years and summed up the preliminary situation of the people’s prevention and control experience reported below for reference.
