近几年来,随着水稻机械化程度在逐年提高,机插面积也相应扩大,但由于插秧机的性能和育秧技术等方面的问题,使机插秧带来不同程度的缺棵,直接影响到机插水稻的产量。因此,把1977—1982年进行机插缺棵补偿试验的资料,加以整理,提供使用各种插秧机允许缺棵的范围,为人工补棵和试制或改进插秧机作业性能作参考。试验在无锡东亭和吴县越溪机械化试点进行。以中秆早、原丰早、昆农选16三个品种,分别采用尼龙、露地和工厂百秧。选用江苏高邮、太仓小苗带土手扶插秧机,苏州产洗根大苗的通用插秧机,日本乘坐式PL620-90型及上海仿日制造的工厂秧小苗配套的插秧机,分别在双季早稻、早三熟、晚三熟及单季稻上进行机插。在机插田内人为的缺1—5棵,均设三次重复,以未缺棵的作
In recent years, with the degree of mechanization of rice increasing year by year, machine insertion area also expanded correspondingly, but due to the performance of rice transplanter and seedling technology and other aspects of the machine transplanting bring varying degrees of lack of direct impact on the machine inserted Rice production. Therefore, the 1977-1982 machine insert missing tree compensation test information to be collated to provide the use of a variety of transplanter to allow the lack of range for artificial make-up and trial or improve the operation of transplanter for reference. Test in Wuxi Dongting and Wu County Yuexi mechanized pilot. Early in the stalk, the early abundance of early Kunming farmers selected 16 three varieties, respectively, nylon, open field and plant 100 seedlings. The selection of Jiangsu Gaoyou, Taicang seedlings with soil hand-held transplanter, pickling seedlings produced in Suzhou universal transplanter, Japan ride type PL620-90 and imitation of Shanghai plant seedlings supporting transplanter seedlings, respectively, in early rice double crop early Three cooked, late three cooked and single-season rice machine plug. In the machine inserted in the field of man-made 1-5, are set three times to repeat, to not miss the tree
