中文摘要	为满足干旱半干旱地区少耕免耕间歇施水播种的要求，设计了2BSSF-3型浅松间歇施水播种机，并对田间试验进行了分析。结果表明：每次施水的平均灌水量为197．6g时，水沿沟流动量少；每次施水的平均灌水量为387g时，水沿沟流动量较大，且相邻水湿润区相接现象较严重，但种子下部水入渗深度明显增加。在两种灌水量条件下的试验结果为：设计点播距离300mm，机组速度0．59m／s时，平均点播距297．4mm，合格率94．7％；平均每次点播粒数1．89，合格率97．2％，重播指数1．82％，漏播指数2．19％。机组速度0．98m／s时，平均点播距311．2mm，合格率92．1％；平均每次点播粒数1．33，合格率95．9％，重播指数1．51％，漏播指数2．67％。种子离水湿润中心距离的平均值都小于设计值20mm，合格率96％；种水同位率99．7％。各项指标均满足农艺和设计要求。
英文摘要	In order to meet the demand of watering sowing intermittently in stubble field without tillage or in field with surface tillage in add and semi-add regions, the 2BSSF-3 type surface tillage and irrigating machine was designed. The field test results were analyzed. The results show that when the average irrigating water is 197.6 g every time, the flowing amount of water along ditches is very little. The flowing amount of water along ditches is relatively greater when the average irrigating is 387 g every time, and the border of wet section had joined, but the deepness of water seeping under seeds increased obviously. The test results under two different conditions of water-irrigation amount show that when the irrigating-sowing machine working at the speed of 0.59 m/s, and the designed distance between seeds is 297.4 mm, the average distance between seeds is 297.4 mm, the eligible rate is 94.7%; the average number of seeds every time is 1.89, the eligible rate is 97.2%, the re-sowing index is 1.82%, and the no-sowing index is 2.19%. When the irrigating-sowing machine working at the speed of 0.98 m/s, and the average distance between seeds is 311.2 mm, the eligible rate is 92.1%; the average number of seeds every time is 1.33, the eligible rate is 95.9%, the re-sowing index is 1.51%, and the no-sowing index is 2.67%. The sowing deepness can meet the demand of design; the average distance ! between seeds and the center of wet soil is all less than the designed number 20 mm, the eligible rate is 96%,and the apposition rate of water and seed is 99.7%. Every index can meet the demand of agronomy and design.
