“…These results indicate that CFOF raised soil fertility and physicochemical properties and that organic fertilizer could contain several active substances, such as humic acid, amino acid, and microbes, among others, which could promote the formation of soil aggregates, making soil more relaxed and breathable, and strengthening the ability to conserve fertilizer and water to a certain degree. These results are similar to those of previous studies [41][42][43]. Soil microbe content, which is often used as an indicator to evaluate soil quality, plays an important role in the soil ecosystem, not only by assuming the responsibility of decomposer but also by promoting nutrient absorption by roots.…”

Chemical fertilizer has been excessively used for high yield of citrus around the world, especially in China; meanwhile, it deteriorates the citrus orchard soil environment. To resolve the conflict, the use of organic fertilizer provides a promising solution. However, the data about organic fertilizer used in citrus orchard is rarely available. Here, four treatments including CK (no fertilizer), CF (chemical fertilizer), OF + CF (chemical fertilizer reduction combined with organic fertilizer; application of N, P2O5, K2O fertilizer and organic fertilizer is 0.564, 0.236, 0.336 and 10 kg/plant), and BF + CF (chemical fertilizer reduction combined with bioorganic fertilizer; application of N, P2O5, K2O fertilizer and bioorganic fertilizer is 0.508, 0.320, 0.310 and 10 kg/plant) were performed in a ‘Ponkan’ (Citrus reticulata Blanco) orchard to evaluate the effect of organic fertilizer on citrus yield, growth, soil properties etc. when nutrients of fertilizer of each treatment were equal except CK. The data obtained in 2019 and 2020 showed that both OF + CF and BF + CF were beneficial to improve soil fertility (soil physicochemical and microbe properties) and citrus growth physiology (growth, nutrient and photosynthesis), alleviate NO3−-N leaching, and promote yields. Comprehensive evaluation indicated that BF + CF was more effective than OF + CF. Together, organic fertilizer has the potential to substitute partial chemical fertilizer with improvement in soil properties, growth physiology, and yield of citrus.

“…The total amount of crop straw in China is vast [1,2] , but resource waste and environmental pollution caused by unreasonable utilization of straw are relatively severe [3,4] . Numerous studies have shown that straw mulching is the best way of orchard soil management in arid areas [5][6][7][8] , with water storage and moisture conservation [9][10][11] , improving soil organic matter content [12][13][14] , suppressing weeds [15,16] , reducing soil erosion [17][18][19] and secondary salinization [20][21][22] , etc., thus improving fruit yield and quality [23,24] . However, the technology has not been widely used due to high labor costs and the orchard fire risk caused by straw.…”

Aiming to lack the function of soil covering in the developed orchard straw mulching machine (OSM), a kind of bilateral counter-throwing soil-covering device was developed to eliminate the orchard fire risk caused by the straw layer. The soil-covering device was suspended at the rear of the OSM. Its core component was a pair of throwing wheels installed on both sides of a frame. Hydraulic motors drove the throwing wheels to take soil on-site and cover the straw layer. The adjustment range of the space between the throwing wheels on both sides was 1.4-2.1 m. Based on the analysis of soil-covering quantity, soil-covering width, thickness uniformity of soil layer, and power consumption, the key parameters such as the radius, the number of the vane, and the minimum rotation speed of the throwing wheels were determined. It was proved that the thickness uniformity of the soil layer by bilateral counter-throwing was better than by unilateral, and bottom throwing was better than top throwing. The blade of the soil cutter consisted of a straight blade and a curved blade, and the sliding-cutting angle was 14°-40°. The field test results showed the soil-covering device had good performance with a width of 1.4-2.2 m, a thickness of the soil-covering layer (TSL) of 23.2-40.7 mm, a standard deviation (SD) of 1.4-2.9 mm, width uniformity of 100%, and leakage rate of zero. The established model, between the thickness of soil-covering layer and trenching depth, throwing angle, and rotation speed of the throwing wheels, has a determination coefficient of 0.9757 and can be used to guide the operating parameters. The soil cutter reduced the power consumption and impact load of the throwing wheels by 64.77% and 60.88%, respectively. This work provides a type of new equipment for the mechanization technology of straw mulching in arid and semi-arid orchards.

Rice straw is a source of organic matter (OM) that improves soil fertility. After rice straw is returned to the soil, increased microbial enzyme activity decomposes organic residues, affecting soil carbon. To evaluate the effects of continuous rice straw return on soil labile organic carbon (LOC) fraction and β-glucosidase (BG) activity in paddy soil, an experiment was conducted with four treatments; Chemical fertilizer treatment (NPK), Chemical fertilizer + rice straw treatment (NPKR), Green manure treatment (GM) and Green manure + rice straw treatment (GMR). Hot water extractable carbon (HWEC) content, permanganate oxidizable carbon (POXC) content, and BG activity were analyzed. HWEC content was 42% higher than in NPKR than in NPK. It was 8% higher in GMR than in GM, but there was no significant difference. In addition, POXC content was 17% higher in NPKR than in NPK. It was 11% higher than in GMR than in GM, but there was no significant difference. BG activity was 36% higher in NPKR than NPK, and 55% higher in GMR than GM. As a result, in paddy soil that are low in OM due to the predominant use of chemical fertilizers, rice straw return is likely to increase OM supply and LOC content in the soil and contribute to carbon cycling.
