合宜密植程度问题近年来受到各方面的重视,许多科学研究机关和农村人民公社都广泛地进行了密度试验,加深了对密植问题的认识。但是到目前为止,这些密植试验资料试整理、分析后发表出来的还不多,因此彼此交流很不够,在确定各种作物的合宜密植程度的原则方面,在建立合理密植的理论方面,仍然感到资料不足,观点分歧。如何进一步把这些资料加以系统分析,从感性认识提高到理性认识,看来是目前很值得做的一项工作。最近读了杨立炯等同志根据80个密植试验所著《水稻合宜密植的生物学基础及共应用原
In recent years, the issue of appropriate density has received much attention from all quarters. Many scientific research institutions and rural people’s communes have conducted extensive density tests and deepened their understanding of the issue of planting close to each other. However, up to now, these close-planting test data have been tried out and analyzed and published in small quantities. Therefore, it is not enough to communicate with each other. In determining the appropriate planting density of various crops, the theory of close planting still feels Insufficient information, different opinions. How to further systematically analyze these data and improve the perceptual knowledge to rational knowledge seems to be a work that is worth doing at present. Recently read Yang Lijiong and other comrades based on 80 close planting test by the "rice biological basis of close planting and co-application of the original
