从学校的实际出发,结合生产劳动,进行农业科学试验,是全面实现培养目标和支援农业生产的一项有效措施。几年来,学校的米丘林科学研究小组,开展了水稻、棉花、红薯、芝麻、蔬菜、果树的试验活动,和耕牛、鸡鸭的饲养繁殖活动。例如在棉花试验中,除进行了土棉和岱子15号嫁接、木槿花与棉花有性杂交改良品种外,还着重研究了棉桃脱落问题。以往我校栽种的棉花连年夏至到小署季节大量脱桃。据观察,不是虫害。脱桃的原因是什么呢?经过大家初步分析,认为可能是到夏至、小满季 Starting from the actual conditions of the school, combining production labor and carrying out agricultural scientific experiments is an effective measure to fully realize the training objectives and support agricultural production. In the past few years, the school’s Michurin Research Group has conducted experiments on rice, cotton, sweet potatoes, sesame seeds, vegetables, fruit trees, and breeding and breeding of cattle, chickens and ducks. For example, in the cotton experiment, in addition to the 15th grafting of ramie and medlar, and the improved hybridization of hibiscus and cotton, the problem of boll shedding was also studied. In the past, cotton planted in our school had been largely defoliated during the summer solstice to the Xiaothai season. It has been observed that it is not pests. What is the reason for the loss of peaches? After preliminary analysis, it is thought that it may be the summer solstice and the small seasons.
