水稻生育期内的供水状况如何,对水稻生长发育影响极大。不同地区或同一地区的不同水稻种类,或同一品种的不同生育期对水分的需求,也都不尽一样。我省气候温和,降水充沛,大多地区均适宜水稻生长发育,但是,春旱、夏旱常有发生,严重威胁水稻的正常发育。研究在我省自然条件下水稻需水状况,对于制定正确的灌溉制度,为水利工程规划设计提供资料都有重要意义。一、试验田基本情况与处理试验于1980年6～10月在贵阳市中曹人民公社中院生产队进行,采用筒测法,大测筒长、宽、高的规格为80×40×100厘米,
The status of water supply during rice growth period has a great impact on rice growth and development. Different regions or regions of different types of rice, or the same species of different growth periods of water demand, are not the same. In our province, the climate is mild with abundant rainfall, and most areas are suitable for rice growth and development. However, spring drought and summer drought occur frequently, which seriously threaten the normal development of rice. Studying water requirement of rice under natural conditions in our province is of great significance to formulating correct irrigation system and providing data for water conservancy project planning and design. First, the basic experimental field conditions and treatment test in 1980 June to October in Caoyang People’s commune, Guiyang City Intermediate People’s Hospital team, the use of drum method, large measuring tube length, width and height of the specifications for 80 × 40 × 100 cm ,
