“…This practice can enhance the effective utilization of soil water by inhibiting soil evaporation, strengthening water conservation and harvesting, and decreasing the wastage of heat loss from the soil to the atmosphere Zhou et al, 2009). At present, the plastic mulched system has been widely used in the oasis irrigation regions of northwestern China because of the enhanced efficiency in water harvesting and improvements in grain yield and resource use efficiency of maize (Chai et al, 2014;Yin et al, 2020b). However, in recent years, the precocity of maize with plastic mulch is remarkably common, and some researchers believed that this phenomenon is premature aging rather than early maturation, and it is a precursor to reduced yield (Bu et al, 2013;Yin et al, 2020b).…”

The reason for this precocity is that transparent plastic mulching often causes extreme high soil temperature in the root zone of maize at the reproductive growth period, leading to senescence of roots and leaves for maize and weakening the stability of yield performance (Bu et al, 2013).…”

“…Therefore, it is important to develop a system on no tillage with plastic re-mulching to maintain maize productivity through the optimization of soil hydrothermal properties. We propose a promising and valuable system in which plastic secondary recycling is used for maize production, which is based on existing findings on the regulatory mechanisms for soil hydrothermal effect (Yin et al, 2016(Yin et al, , 2020b. The central hypothesis of this promising and valuable system can decrease the change of air-soil temperature amplitude and coordinate water demand contradiction to maintain high maize productivity while reducing the input of plastic in arid regions.…”

Plastic is a valuable mulching measure for increasing crop productivity in arid environments; however, little is known about the main mechanism by which this valuable technology actuates spatial–temporal changes in soil hydrothermal effect. So a 3-year field experiment was conducted to optimize soil hydrothermal effect of maize field with three plastic mulched management treatments: (1) no tillage with plastic re-mulching (NM), (2) reduced tillage with plastic mulching (RM), and (3) conventional tillage with annual new plastic mulching (CM). The results showed that NM treatment increased soil water content by 6.6–8.4% from maize sowing to seedling stage, than did CM, and it created a good soil moisture environment for sowing of maize. Also, NM had greater soil water content by 4.8–5.6% from maize silking to early-filling stage than had CM, and it made up for the abundant demand of soil moisture for the vigorous growth of maize filling stage. The NM treatment increased water consumption (WC) before maize big-flare stage, decreased WC from big-flare to early-filling stage, and increased WC after early-filling stage. So NM treatment effectively coordinated water demand contradiction of maize at entire growing season. NM decreased soil accumulated temperature (SAT) by 7.0–13.0% at maize sowing to early-filling stage than did CM, but NM had little influence on the SAT during filling stage. In particular, the treatment on NM had smaller absolute values of air–soil temperature differences than RM and CM treatments during maize filling stage, indicating that NM treatment maintains the relative stability of soil temperature for ensuring grain filling of maize. The NM treatment allowed the maize to grow in a suitable hydrothermal status and still maintained high yield. In addition, NM treatment obtained higher net income and rate of return by 6.4–11.0% and 44.1–54.5%, respectively, than did CM, because NM treatment mainly decreased the input costs for plastic and machine operations. Therefore, the NM treatment can be recommended as a promising technique to overcome simultaneous heat stress and water shortage in arid environments.

“…Therefore, an intercrop design may be chosen to increase soil cover during the whole cropping period. An increased soil cover by intercropping further minimizes soil erosion, evaporation and allows for allelopathic effects between plants [3,25]. Intercropping can also be a measure to reduce total crop failure [5,26].…”

Poppy (Papaver somniferum L.) Intercropping with Spring Barley and with White Clover: Benefits and Competitive Effects

et al. 2021

Poppy seed production is susceptible to abiotic and biotic stress and weed infestation, which introduces the risk of total crop failure. For the purpose of risk minimization, poppy was grown in additive intercropping systems with early and late sown white clover and spring barley sown at three different densities in a three year field trial to assess their roles in poppy cropping while adding ecological benefits to the crop rotation. Poppy yielded between 798.7 and 1293.1 kg ha−1, with no significant yield effects of intercropping with white clover, compared to poppy sole-cropping. Dry matter, height, leaf area index and C/N ratio of the poppy plants were not significantly impacted by the clover intercrop either, independent on its sowing date. Higher poppy yields (695.6–918.8 kg ha−1) and LERs (1.11–1.84) in the poppy–barley intercrop were achieved in 2018 and 2020 compared to 2019 (≤361.5 kg ha−1, LER ≤ 0.99), mainly due to differences in seeding dates, precipitation and nutrient availability. Therefore, previous seeding of poppy limits competition when intercropped with barley while white clover and poppy can be sown at the same time. The effect of barley seeding densities on the intercrop performance was small as was the influence of intercropping on weed cover, number and biomass. The weed regulating effect needs to be further examined, however, we conclude that intercropping of poppy is a promising strategy for its cultivation, in terms of minimizing the risk of total yield losses when precisely managed.

“…Intercropping is a kind of traditional Chinese agriculture with a long history, can not only improve the index of multiple cropping of arable land (Yang et al, 2013), increase grain production and farmers' income , but also effectively alleviate the problems of low fertilizer use efficiency and negative environmental effect (Foley et al, 2011;Gebru, 2015;Yin et al, 2020). A large number of studies have shown that due to the complementary and mutually beneficial effects of crop species, intercropping between gramineous crops and leguminous crops can increase the utilization of nutrient resources and affect the biological characteristics of rhizosphere soil (Li et al, 2014).…”

The solubilization and mineralization of phosphorus by phosphate-solubilizing bacteria (PSB) is one of the most important bacterial physiological characteristics in the soil biogeochemical cycle. Through the isolation and screening of microorganisms in the rhizosphere soil of intercropped soybean in Ya’an, Renshou and Chongzhou, 9 PSBs with high phosphorus solubilizing ability were identified. It mainly belongs to Bacillus and Pseudomonas. The phosphate solubility of Bacillus aryabhattai B8W22 is as high as 388.62 µg·mL-1. The physiological and biochemical characteristics of each strain showed that it can secrete organic acids such as formic acid, acetic acid lactic acid and pyruvic acid. In addition, all strains can produce indole acetic acid and siderophores that promote plant growth. Seed germination experiments also showed that the phosphorus solubilizing bacteria isolated in this research have a certain ability to promote plant growth.IMPRTANCEBacillus aryabhattai from rhizosphere soil of intercropped soybean has high phosphate-solubilizing ability, could produce indole acetic acid and siderophores that promote plant growth, and are of great significance in reducing the application of chemical phosphate fertilizers and promoting sustainable agricultural development.
