Abstract

Abstract:

【Objective】Soil fertility is essential to crop growth and yield. The arable land per capita in China is low, and approximately 21.95% of the arable land has serious barriers for crop production. To ensure food security, it is necessary to exploit cultivated land reserves, along with the efforts to increase the productivity of arable land. Therefore, it is important to cultivate crops that can tolerate low-fertility in marginal lands, to avoid land competition with other main crops and meet increasing food demand. To better use marginal land for sorghum production, a field experiment was conducted in Yuci, Shanxi Province in 2019, to study the variation in low-fertility tolerance ability of different sorghum cultivars. This study aimed to identify the sorghum cultivars with strong tolerance to low-fertility and the index to evaluate low-fertility tolerance, and the results would provide evidence for sorghum selection in marginal land cultivation.【Method】In this study, a field experiment including 23 sorghum cultivars was conducted with contrasting soil fertility treatments, including high soil fertility (control) treatment and low soil fertility treatment (stress). A total of 15 parameters including yield and yield components, dry matter accumulation of shoot and nutrient uptake were investigated. The low-fertility index of each parameter was calculated. Principal component analysis (PCA) and cluster analysis were used to evaluate low-fertility tolerance and identify low-fertility tolerant cultivar. Low-fertility index and comprehensive evaluation value were used, combined with regression analysis and correlation analysis, to identify the optimal indicators for low-fertility tolerance.【Result】The results showed that the yield, grain number per spike, harvest index, dry matter accumulation at harvest and after heading, leaf area index (LAI), panicle length and width of sorghum were decreased by the low-fertility stress, compared with those in high-fertility plots. The decreasing rate was as follows: dry matter accumulation after heading>yield>grain number per spike>dry matter accumulation of shoot>LAI>panicle width>harvest index. The accumulation of N, P, K in both grains and shoot above ground was also decreased. The N accumulation was the most sensitive to low-fertility stress. The 15 parameters were categorized into five comprehensive indexes (the cumulative contribution rate was 89.28%) by principal component analysis, and the comprehensive evaluation value (D) of the low-fertility tolerance was calculated. According to the D value and the cluster analysis, the 23 sorghum cultivars were divided into four tolerance levels. Six, seven, seven and three cultivars were classified as stronger (0.633≤D≤0.755), strong (0.467≤D≤0.592), weak (0.310≤D≤0.421) and weaker (0.166≤D≤0.246) tolerance to low fertility, respectively. The cultivars Jiniang 2, Liaoza 19, Jinza 18, Jinza 22, Jinfeng 301 and Jinza 28 had the highest D value. Stepwise regression analysis was used to establish the optimal regression equation to evaluate the sorghum low-fertility tolerance. The yield, dry matter accumulation of shoot, N accumulation above ground, grain P accumulation, grain K accumulation and panicle width were selected, which had significant effects on the tolerance to low-fertility stress. The low-fertility index of yield, dry matter accumulation of shoot, N accumulation in shoot above ground, P accumulation in shoot above ground, grain N accumulation and grain P accumulation were significantly correlated with D value. The correlation coefficients were 0.845, 0.836, 0.766, 0.778, 0.761 and 0.757, respectively. 【Conclusion】There were large variation in low-fertility tolerance of the 23 sorghum cultivars. The cultivars of Jiniang 2, Liaoza 19, Jinza 18, Jinza 22, Jinfeng 301 and Jinza 28 were significantly tolerant to low-fertility land. The low-fertility index of grain yield, dry matter accumulation of shoot, N accumulation above ground and grain P accumulation were recommended in rapid screening of low-fertility tolerant sorghum cultivars.
