Table1_Understanding Ecological Agricultural Technology Adoption in China Using an Integrated Technology Acceptance Model—Theory of Planned Behavior Model.pdf
With the development of the economy and society, environmental pollution and resource waste problems are emerging, especially in agricultural production, and the adoption of ecological agricultural technologies is a prerequisite to alleviate ecological pressure. Based on the Technology Acceptance Model—Theory of Planned Behavior (TAM-TPB) and using research data from Hubei, Hunan, and Anhui provinces, this paper empirically analyzes the factors influencing farmers’ intention to adopt rice and shrimp crop technologies using the PLS-SEM method. The configuration path of high technology intention was further investigated by the fsQCA method. The results showed that: 1) farmers’ intention to adopt rice-shrimp crop technology was mainly positively influenced by behavioral attitude, subjective norm, perceived behavioral control, behavioral attitude; 2) Perceived usefulness and perceived ease of use had a direct effect on farmers’ intention to adopt and an indirect effect with behavioral attitude as a mediating variable, while perceived ease of use had a positive effect and perceived usefulness did not. In doing so, four configuration paths of high technology acceptance intention were obtained. Given this, this paper makes relevant suggestions, suggesting that the relevant departments focus on the comprehensive benefits of rice-shrimp crop technology; agricultural technology departments provide technical assistance to farmers, and village committees organize regular inter-farmer exchanges.</p

Determination of optimum irrigation strategies and effect of drip irrigation system on growth and water use efficiency of pear jujube in Loess Hilly region of northern Shaanxi
The aim of this study is to explore suitable drip irrigation system on the water saving and high yield of pear-jujube from 2009 to 2012 years in the mountain of northern Shaanxi. The treatments consisted of combinations of 5 drip irrigation systems (DP). The irrigation quota of DP-1, DP-2 and DP-3 treatment was 100 m3 hm-2, 135 m3 hm-2 and 180 m3 hm-2, respectively, irrigated 4 times. The irrigation quota of DP-4 and DP-5 treatment was 135 m3 hm-2 and irrigated 3 and 2times, respectively; and with no irrigation as the control (C). Results indicated that bearing branch length of jujube, fruit set and yield of different drip irrigation system are significantly better than C (P3 hm-2. And they are increased by 47.7% and 13.2% compared with C, respectively. In addition, the water consumption of different irrigation treatment increases along with the increasing of irrigation amount. And the DP-3 treatment is the highest in different years. The water use efficiency of pear-jujube of low irrigation quota is better than the high irrigation quota. Water use efficiency of 135 m3 hm-2 and irrigated 2 times treatment is the best, which is 1.92 m3 hm-2. Considering the lack of high annual precipitation, we conclude that DP-5 treatment was the best drip irrigation system in the mountain of northern Shaanxi.</div

Effects of Feldspathic Sandstone Addition on Microbial Biomass, Soil Enzyme Activity, and Bacterial Community Structure of Sandy Soil
Desertification is a serious environmental problem worldwide. In this study, a long-term field experiment was conducted to investigate the effects of feldspathic sandstone on remediation of sandy soil. The results indicated that feldspathic sandstone addition increased the soil moisture, available N, P, K content, organic matter content, and cation exchange capacity of the sandy soil. The microbial biomass carbon increased 130.12%, 135.45%, and 120.34% in the compound soil with the feldspathic sandstone and sand mass ratio of 1:1, 1:2, 1:5, respectively, and the microbial biomass nitrogen increased 102.38%, 107.45%, and 81.69%, respectively. Meanwhile, soil urease, catalase and surface activity were significantly enhanced (p Acidobacteriota was more abundant in sandy soil while Proteobacteria and Firmicutes were more abundant in compound soil. Proteobacteria and Firmicutes are involved in nutrient cycling and plant residues degradation, respectively. Their enrichment is beneficial for soil quality improvement. Redundancy analysis indicated that available N, K, organic matter and soil moisture content are key factors that involved in the assembly of bacterial community. Overall, adding feldspathic sandstone into sandy soil improved soil physiochemical properties, enhanced soil microbial activity and optimized the bacterial community, which would ultimately improve the quality and ecological function of the sandy soil.</p
