稻田多熟制是浙江省实现粮食高产稳产的主要而有效的途径,探讨多熟制条件下实现作物高产稳产的用肥技术对指导农业生产有重要意义.但是,以往的作工多为一季作物或一个地点的研究方式,缺乏研究的系统性和代表性.种植制同所处地区的地理自然环境和社会经济条件有非常密切的关系,因此必须对不同种植方式进行多次循环和多个地点的系统定位研究.鉴此,我们在浙江省四大农区中选取有代表性的11个地点,进行了三个轮作周期的定位观察研究.现将主要研究结果报道如下.一、材料与方法1.试验地点和供试土壤
The multi-cropping system in paddy field is the main and effective way to achieve high and stable grain yield in Zhejiang Province. It is of great significance to discuss the use of fertilizing technology to achieve high and stable crop yield under multi-cropping system in order to guide agricultural production. However, Or a place of study, the lack of systematic and representative research.Planting system with the geographical geographical environment and socio-economic conditions are very close relationship, it is necessary to different planting methods for multiple cycles and multiple locations Of the system positioning research .Therefore, we selected four representative areas in Zhejiang Province, 11 locations, conducted a three-wheeled cycle positioning observation study.The main results are reported as follows.Materials and methods 1. Test site and test soil
