“…Some studies have observed that organic mulching has a significant positive effect on both fruit yield and quality. Ye et al [58] showed that mulching significantly increased the yield and quality of Camellia oleifera, which was consistent with previous results for apple trees [59], peach trees [57], jujube trees [60], and pistachio trees [56]. The present study suggests that all mulch treatments were associated with an increasing trend in nut yield and quality compared with the nonmulching treatment.…”

Worldwide, a huge amount of solid fermented waste is produced every year during mushroom production. The rational utilization of spent mushroom substrate (SMS) is conducive to environmental protection and the sustainable development of agriculture. The aims of this work were to analyze the effects of the SMS mulching thickness on the soil environment, weed suppression, leaf nutrients, and nut traits in a hazelnut plantation and provide a theoretical basis for the scientific and reasonable utilization of SMS. An SMS mulching experiment with four mulching thickness treatments (MT1: 5 cm, MT2: 10 cm, MT3: 15 cm, and CK: 0 cm) was conducted in a semi-arid area of North China in 2019. The soil properties, weed control efficiency, leaf nutrient content, and nut yield and quality characteristics of these treatments were all measured and analyzed. The results showed that (1) the average soil temperatures of MT2 and MT3 at different soil depths were 0.73–1.78 °C and 1.18–2.50 °C lower than when no mulch was used in warm weather and 0.67–1.05 °C and 0.99–1.56 °C higher than when no mulch was used in cold weather. The average soil moisture content of MT1, MT2, and MT3 at different soil depths was 6.27–8.13%, 10.66–17.23%, and 7.26–12.81% higher than that of CK, respectively. There were no significant differences in the soil bulk density or porosity among the four treatments. The average soil nutrient contents (soil organic matter and available N, P, and K) of MT1, MT2, and MT3 were 7.05–15.23%, 14.90–38.93%, and 17.42–40.11% higher than those of CK, respectively. Soil enzymatic activities of these treatments followed the order MT3 ≈ MT2 > MT1 > CK. (2) MT2 and MT3 both had high levels of weed control efficiency: 55.66–92.93% and 70.43–97.90%, respectively. (3) The leaf N, P, K, and SPAD increased significantly under MT2 and MT3 by about 10% compared with the CK. (4) MT2 effectively increased the nut size, nut and kernel mass, and crude fat content of the nut (CFC). In general, the short-term field experiment clearly showed that SMS is a superior mulching material for improving the soil environment and plant growth, and 10 cm thickness is suitable for mulching practice.

“…The results showed that both straw mulching and jujube branch mulching could well enhance soil water storage capacity (Fig. 5), reduce water consumption amount during the whole growth period (Table 2), and improve the soil moisture environment in the rain-fed jujube orchard, which was consistent with previous research results (Pan et al, 2018;Wang et al, 2018). In this study, straw mulching was better than jujube branch mulching in improving the soil moisture environment in rain-fed jujube orchard.…”

“…In addition, there is little irrigation in the loess hilly region, and most of the crop growth depends on natural precipitation (Qin et al, 2014;Gao et al, 2020). Water shortage severely restricts the development of agriculture and forestry in the loess hilly region (Jin et al, 2018). How to reasonably and efficiently utilize the limited natural precipitation in the loess hilly region has become the focus and main trend.…”

BackgroundWater shortage is the main bottleneck restricting the healthy and sustainable development of rain-fed jujube orchards in the loess hilly region of China. Given the functions of mulching on soil moisture conservation, evaporation reduction, and water use efficiency improvement, maize straw mulching (SM) and pruned jujube branch mulching (BM) were applied to rain-fed jujube orchards in this study. Soil moisture dynamics, soil water storage, water consumption, and soil moisture attenuation after typical rainfall under SM, BM, and clean tillage (CT) were systematically studied. Results(1) The 0-60 cm soil layer was the seasonal fluctuation layer of soil moisture under SM, BM, and CT in both the normal precipitation year and the dry year. The 0-60, 60-160, and 160-280 cm soil layers under CT all obtained the lowest soil moisture content in the three experimental years. The soil moisture content of each soil layer under SM and BM was higher than that under CT, and SM showed the most obvious effect of increasing soil moisture. (2) SM and BM showed significant soil water storage effect in all the jujube growth stages in both the normal precipitation year and the dry year, and SM had a better water storage effect than BM. (3) SM and BM reduced the water consumption amount in each jujube growth stage. SM reduced water consumption amount by 94.3, 60.8, and 121.3 mm compared with CT in the whole growth period of jujube in 2014, 2015, and 2016, respectively. The water consumption amount of BM decreased by 34.8 mm and 31.0 mm respectively compared with that of CT in the whole growth period in 2014 and 2015. (4) CT had the maximum soil moisture loss rate under continuous drought after rainfall. The soil moisture loss rate of CT was above 37.3% on the eleventh day after the typical rainfall in 2014, 2015, and 2016. With the extension of drought, the soil moisture loss rate under SM increased slowly, while it increased rapidly under CT. ConclusionThis study suggests that straw mulching is the best mulching measure for rain-fed jujube orchards, and the pruned jujube branches can also be used for in-situ mulching, which can also obtain a certain moisture conservation effect.

“…The adverse impacts of water deficit on fruit yield can be alleviated by changing the canopy architecture and removing the outer 30% of all major branches via pruning; severe summer pruning (SSP) is especially effective [ 8 , 30 ]. When the canopy is pruned, the leaf area is decreased, which reduces the water demand of the tree and ultimately enhances the tree water status [ 8 ].…”

Water scarcity is one of the greatest concerns for agronomy worldwide. In recent years, many water resources have been depleted due to multiple factors, especially mismanagement. Water resource shortages lead to cropland expansion, which likely influences climate change and affects global agriculture, especially horticultural crops. Fruit yield is the final aim in commercial orchards; however, drought can slow tree growth and/or decrease fruit yield and quality. It is therefore necessary to find approaches to solve this problem. The main objective of this review is to discuss the most recent horticultural, biochemical, and molecular strategies adopted to improve the response of temperate fruit crops to water stress. We also address the viability of cultivating fruit trees in dry areas and provide precise protection methods for planting fruit trees in arid lands. We review the main factors involved in planting fruit trees in dry areas, including plant material selection, regulated deficit irrigation (DI) strategies, rainwater harvesting (RWH), and anti-water stress materials. We also provide a detailed analysis of the molecular strategies developed to combat drought, such as Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) through gene overexpression or gene silencing. Finally, we look at the molecular mechanisms associated with the contribution of the microbiome to improving plant responses to drought.
