我所地处宁绍平原水网稻区,地下水位较高,土质粘重,属于青紫泥土壤。在这样的土粘肥缺、杂草较多的三熟制地区,稻田种麦究竟采取什么播种方式为好,这是个争论较久的问题。从1966年冬起,绍兴东湖农场开始进行这方面的研究,以后我所继续开展这一工作。根据10年研究结果表明,在本地条件下,以等行距穴播方式最好,条播第二,撒播较差。如1967—1978年,经过10年累加50次重复对比试验,等行距穴播比撤播平均增产14.1%,等行距穴播增产的有45次,增产幅度为0.6—57.6%,平产的一次,减产的4次,减产幅度为0.9—13.2%,经统计分析,等行距穴播比撒播增产极显著。等行
I am located in Ningshao plain water network rice area, high groundwater level, soil sticky, belonging to the soil purple soil. It is a matter of debate over what kind of sowing is the best way to sow rice in paddy soils, where there is a lack of clay and more weeds. From the winter of 1966, the research on this area began at Donghu Farm in Shaoxing. After that, I continued to carry out this work. According to 10 years of research results show that under local conditions, the best way to broadcast at the same distance, broadcast second, poor broadcasting. For example, from 1967 to 1978, after 50 years of repeated comparison tests for 10 years, the average distance between planting and sowing increased by 14.1% and the planting distance increased by 45-5 times with a yield increase of 0.6-57.6% Of the 4 times, the rate of decrease of 0.9-13.2%, by statistical analysis, such as row spacing broadcast sowing than significant increase.
