商品育秧基质与营养土不同配比对水稻秧苗素质及产量的影响

The Effect of Different Proportions Application between Nursery Substrate and Nutritive Soil on Seedling Quality and Yield

水稻基质育秧技术是水稻机械育插秧技术的重要组成部分,是破解取土难的有效途径。本研究通过采用商品育秧基质与营养土不同配比田间试验,考察不同配比培育的水稻秧苗各项素质及最终产量,以期筛选出适宜大面积生产推广应用的节本配比。试验表明:采取2/3基质、1/3菜园土的处理为最佳配比。该配比在提高秧苗盘根效果、利于机插作业的基础上,机插秧大田可节约育秧成本14~16元/667 m^2。

The technique of rice nursery substrate was an important part for the mechanization of rice planting and seedling,and it was an efficient way to save the problem of getting soil,the test investigated the seedling quality and yield of different proportions application between nursery substrate and nutritive soil,in order to find the best proportion and suitable for large-area popularization and application.The result indicated that the best proportion between substrate and vegetable garden soil were 2：1.This proportion can enhance the effect on roots of seedling,and benefited the mechanically transplanting,it could economize the cost of seedling with 14~16 yuan/667 m^2.
