Effects of Soil Conditioner on Chemical Properties of Saline Alkali Soil and Rice Growth in Northern Shaanxi Provcine
[Objective] The effects of different amount of soil conditioner on soil chemical properties and rice growth in saline alkali soil were studied in order to provide reference for saline alkali soil improvement and rice planting in Northern Shaanxi Province.[Methods] Taking rice in saline alkali soil of Dingbian County in Northern Shaanxi Province as the research object
the field experiment was carried out with different soil conditioner application rates (1 000
1 500
2 000 kg/hm2).[Results] ① With the increase of soil conditioner dosage
the pH value and total water soluble salt content of 0-40 cm soil in each treatment were decreased significantly
and the reduction range of each treatment was 0.89%~5.02% and 6.78%~13.56%
respectively. ② After adding soil conditioner
the content of soil organic matter increased significantly
while there was no significant change in the content of total nitrogen
available phosphorus and available potassium. ③ When the amount of soil conditioner was 1 500 kg/hm2 and 2 000 kg/hm2
the tiller number and plant height of rice were significantly increased. ④ When the application amount of soil conditioner was 1 000~2 000 kg/hm2
the rice yield was increased by 5.49%~24.77% compared with control group.[Conclusion] Considering the yield and benefit of rice
the suitable rate of soil conditioner is 1 500 kg/hm2 for rice planting.
