不同措施对碱化土壤培肥及水稻植株养分吸收的影响
The influence of different fertilizering measures on soil fertility and nutrient uptaking of rice plant in alkaline soil
摘要
Abstract
In order to find out the influence of NPK nutrient uptakeing of rice plant in salinity-alkalinity stress condition, different fertilizing measures were studied on the Qianjin farm in Ningxia. The results showed that soil pH value and total salt content reduced at different degree regardless of cultivated land or wasteland after harvest. Soil alkali-hydro nitrogen content after harvest increased by 67.2% and 24.5% respectively, rapidly-available phosphorus reduced by 3.6% and 52.3% , and rapidly-available potassium content reduced by 5.2% and 15.8% . In different fertilizing measures, rice stems, leaf total nitrogen content showed a rising trend first, and then a declining one, while total phosphorus was all in a declining trend. The total potassium content showed first rising gently and then declining.关键词
