| Abstract: | The results are as follows： Yield and net income of lotus roots planted in zhu-yu-xing-zasha-ni-rou field were increased by 2145 - 17520 kg and 8330 - 69330 yuan respectively, after adding K2O from 75kg to 225kg per hectare. Yield and net income of lotus roots planted in zhu-yu-xing-shani-rou field were increased by 2940 - 17280 kg and 11510 yuan - 68370 yuan respectively, and an- tiviral ability of lotus roots was enhanced, and quality was improved, after adding K2O from 75kg to 225kg per hectare, however, yield and starch content were significantly decreased after adding K2O more than 225kg per hectare. In a word, yield and income of lotus roots are increased most, and quality is improved most after adding K2O 225kg per hectare, therefore, this way should be popularized for increasing benefit and farmers＇ income. |
