丽水地区位于浙江西南山区,山区冷浸田面积大,分布广,总计有40余万亩,占全地区稻田面积的三分之一。由于冷浸田水热条件差,水肥气热不协调,土壤肥力低,水稻生长不良,亩产一般只有四、五百斤,低的只有一、二百斤。为此,地区科委于1975年组织起全区性的冷浸田改良研究协作组,进行了长期多点的试验。经过六年的研究,加深了对冷浸田成因及其本质的认识;总结出一套改良技术措施,在实际改良中取得了显著的改良和增产效果。本文就是介绍我区在山区冷浸田改良研究中所取得的一点经验和体会。
The Lishui area is located in the mountainous area of southwest Zhejiang Province. The cold paddy fields in the mountainous areas are large in area and widely distributed with a total area of more than 40 million mu, accounting for one third of the paddy area in the entire region. Due to poor water and heat conditions in the cold-dip fields, there is a lack of harmony between water and fertilizer, low soil fertility and poor rice growth. Generally only four or five hundred jins per mu are produced, and only one or two jin is low. To this end, the regional science and Technology Commission in 1975 organized a regional co-Cold Improvement Research Group, conducted a long-term multi-point test. After six years of research, we have deepened our understanding of the causes and the nature of cold dip fields. We have summarized a set of improved technical measures and made significant improvements and increased yields in the actual improvement. This article is to introduce our district in the improvement of cold paddy fields in the study gained some experience and experience.
