| Abstract: |
| The effects of soil conditioner (0, 300, 600 kg·hm-2) on soil salt content and pH value, as well as the growth, yield and quality of Kirin watermelon ‘Meidu’were measured through field experiments in Yinchuan, Ningxia in 2022. The goal was to provide a theoretical basis and technical support for improving saline\|alkaline soils and achieving high\|yield, high\|efficiency production of Kirin watermelon. Results showed that soil salt content and pH value decreased with the increase of application rate of soil conditioner. Compared with no soil conditioner application (CK), the soil salinity in 0~20 cm of the treatments with conditioner application rate of 300 kg·hm-2 and 600 kg·hm-2 decreased by 23.20% and 27.99%, respectively, and soil pH decreased by 1.87% and 3.62%, respectively. Soil conditioner treatments increased soil nitrate nitrogen, ammonium nitrogen, available phosphorus contents and watermelon main vine length, stem thickness, leaf area, leaf SPAD value and photosynthesis at different extent, and the 600 kg·hm-2 treatment had a better promotion effect. Compared with CK, the fruit yield of Kirin watermelon increased by 6.72% and 10.97% with 300 kg·hm-2 and 600 kg·hm-2 of soil conditioner, respectively. The peel hardness and fruit diametar and vertical diameter of watermelon increased with the application of soil conditioner, and the differences between the 600 kg·hm-2 and CK treatments were significant (P<0.05). Meanwhile, the application of 600 kg·hm-2 significantly increased soluble solids and lycopene content of watermelon hearts, which were 5.66% and 3.54% higher than that of the CK treatment, respectively. In conclusion, the soil conditioner significantly reduced the salt content and pH value of saline\|alkali soil, increased the soil nutrient contents, and simultaneously promoted the growth of Kirin watermelon, improving both its yield and quality. The recommended application rate of soil conditioner was 600 kg·hm-2 in the experiment. |
