2.Put subsequently and intertill respectively once in seedling, seedling stage, tillering phase, note timely uprooting weed.Irrigation quantity is 750m
3/ 667m
2, early stage, each irrigation quantity was 20m
3, the later stage is 25m at every turn
3, each promptly and accurately record irrigation quantity.
(1) impact of different amount of nitrogens on drip irrigation rice tillering
The rice stem tiller of the different amount of nitrogens of table 1 is counted investigation result table (ten thousand strains/hm
2)
* data from the mean value of 2012 annual field tests, between different letter representations processing, difference reaches 0.05 conspicuous level.
Table 1 can find out, in tri-leaf period (May 12), the result of investigation shows that the basic seedling amount of each processing is substantially similar, respectively processes difference not remarkable.Show with the investigation result of fringe phase beginning (June 22) in tillering phase (May 23): with the rising of amount of nitrogen, tiller and be the trend increasing, and significant difference between each processing.The investigation result of full heading time (July 16) shows fertilizer treatment (N
300and N
400) stem tiller base this is similar, process higher than other, and have significant difference with other processing; Significant difference between other three processing, with the rising of amount of nitrogen, tillers and is the trend increasing.
(2) impact of different amount of nitrogens on drip irrigation Yield And Yield Components
The impact of the different amount of nitrogens of table 2 on drip irrigation paddy rice yield and its components
* data from the mean value of 2012 annual field tests, between different letter representations processing, difference reaches 0.05 conspicuous level
As can be seen from Table 2, applied nitrogen can significantly improve output within the specific limits, and it is mainly reflected in number of productive ear, grain number per spike, the real grain number executing nitrogen processing and can significantly improve drip irrigation paddy rice.Between different amount of nitrogens are processed, with the rising of amount of nitrogen, the trend that number of productive ear, grain number per spike, real grain number all become to rise; But in the time that nitrogenous fertilizer sowing amount is excessive, N
400every data decrease; N
300process every data be significantly higher than other processing.
Based on the above results, can find out, when phosphorus potash fertilizer drops into (monoammonium phosphate 210kg/hm when consistent
2, potassium sulfate 120kg/hm
2), best nitrogenous fertilizer input amount is 310kg/hm
2, i.e., when paddy rice under-film drip irrigation cultivation, the optimum proportion of nitrogen phosphorus potassium is 3.1:2.1:1.2.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
