Research on High Yield Cultivation Techniques of Mechanical Transplanting Rice with Total Straw Returning in Huaibei Area
摘要
Abstract
In order to study the key technology for high-yielding cultivation of mechanical transplanting rice under the condition of to-tal straw returning, some special experiments were conducted from 2011 to 2014, so that we can have a comparative study on the ef-fects of different cultivation measures on yield and its structure of mechanical transplanting rice. The results showed that, Lianjing 7, Ningjing 4 and Lianjing 11 were better than others according to the performance of comprehensive trait, and they were easy to achieve high and stable yield. The yield of mechanical transplanting rice was decreased with the delay of sowing date, but when we used Chaimihe and Yuanda material for rice seedling, the yield would increased by 4.32%and 3.55%respectively, and the real output was the highest as 22.5 kg/667 m2 N. The yield reached its maximum as mechanical-transplanting plant spacing was 11.7 cm and 13.0 cm, the yield and nitrogen rate was parabola relationship. The yield was increased by 8.7% under the condition of total straw return-ing, water-saving irrigation mode of alternate drying-wetting. Applying silicon fertilizer, Aizhuangfeng and Bihu, the real outputs would exceed 10.5 t/hm2. Therefore, under the condition of total straw returning in Huaibei area, high-yielding variety should be se-lected by mechanical transplanting method, early sowing date at suitable time and close planting. In addition, with increasing nitrogen fertilizer reasonably and implementing water-saving irrigation, and matching seedling raising materials and using of silicon fertilizer and Aizhuangfeng, all these would contribute to realize a large area of high yield by mechanical transplanting method.关键词
