“…In addition, irrigation level has an important influence on the variations of evapotranspiration, especially in a greenhouse [11]. Several studies indicated that ET c under a high irrigation amount is typically greater than that under a low irrigation amount [28,[58][59][60]. The results of the present study showed that the seasonal total ET c values in both years under the W3 treatment were 11.4% and 31.1% higher than under the W2 and W1 treatments, respectively.…”

“…This result could be attributed to the differences in soil water content between the soil body and root cell, resulting in a water potential gradient. A higher soil water potential gradient can effectively promote water migration in the soil-plant-atmosphere [28].…”

“…Although there have been some dynamic dual K c models, these models rarely consider the effect of the plant temperature constraint on T r , which could result in an inaccurate estimation of ET c . In addition, irrigation level is also an important factor in estimating evapotranspiration; several studies showed that ET c has an increasing trend with the increase in irrigation amount [11,28,29]. However, applying the dual K c model to quantify ET c and its component of greenhouse tomatoes under different irrigation conditions is still limited.…”

Accurate quantification of evapotranspiration (ETc) and its components are critical for enhancing water use efficiency and implementing precision irrigation. A two-year experiment was conducted for greenhouse-grown tomatoes under mulched drip irrigation with three irrigation treatments during 2020–2021 in Northeast China. Three different irrigation treatments were applied by setting upper and lower soil moisture irrigation thresholds (i.e., W1, 65%θFC–75%θFC, W2, 75%θFC–85%θFC, W3, 85%θFC–95%θFC, respectively, where θFC is field capacity). In this study, a modified dual crop coefficient (Kc) model was proposed to simulate daily ETc, plant transpiration (Tr) and soil evaporation (Es). The simulations of the model were validated against observed data from the sap flow system combined with the soil water balance method. The controlling factors on the variations of evapotranspiration and its components were also identified by using the path analysis method. Results showed that the modified dual Kc model can accurately simulate daily ETc, Es, and Tr for the greenhouse tomato under different irrigation conditions, with the coefficients of determination ranging from 0.88 to 0.98 and the index of agreement higher than 0.90. The seasonal cumulative ETc of tomato for W1–W3 were 138.5–194.4 mm, of which 9.5–15.8% was consumed by Es. Path analysis showed that the net radiation (Rn) was the dominant factor controlling the variations of Tr and ETc during the growing seasons. The canopy coverage degree (Kcc) was the dominant controlling factor of Es, while the temperature (Ta) was the primary limiting factor affecting Es. This study can provide reference information for developing proper irrigation management in a greenhouse-grown tomato in the north cold climate regions.

“…Biodegradable plastics were introduced to the market in the 1980s and the biodegradable materials used at that time belonged to the so-called first-generation and could be used in less demanding applications, e.g., in the packaging industry. Modern biodegradable polymers (3rd generation) are materials that are used not only in the packaging industry but also in other industries [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

“…In modern agriculture, single or two-layer mulch films made of bio-based and biodegradable polymers are more and more often used as an alternative to those produced from non-renewable sources (crude oil) [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. There is a significant progress on the use and implementation of experimental materials that have a huge degradation potential (with appropriate composting conditions) and are produced from bio-based raw materials [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ].…”

Comparison of Physical and Thermal Properties of Mulching Films Made of Different Polymeric Materials

The development of polymer materials causes their huge expansion into various areas of everyday life, as well as plant and animal production. Their chemical resistance, good physical properties, and ease of processing result in an increasing use of this group of materials. Outdoor plant production both in open plantations and greenhouses requires various types of materials supporting the vegetation process as well as protecting against pests and weeds. A large group here are various types of materials used for covers of field crops, the main role of which is to prevent uncontrolled and excessive growth of weeds and thus reduce the use of herbicides as plant protection products. Cover films also have other important functions, such as reducing direct water evaporation, better moisture retention around the root system, increasing soil temperature (faster vegetation), etc. However, as always, the problem of introducing new material into agriculture production and the difficulty of its disposal arises. In recent times, farmers’ interest in various forms of mulch to protect crops and increase yields has grown significantly. In the publication, the authors attempted to analyze selected commercial properties, but also mulch produced on a laboratory scale, based on biodegradable and petroleum-derived materials.
