In recent years, although breakthroughs have been made in the field of biodegradable mulch, due to various reasons, its industrialization and promotion and application have been slow.

First, the mechanical strength is generally insufficient, and large-scale operation is difficult, which is one of the important reasons that limit the wide application of biodegradable mulches. The physical and chemical properties of the biodegradable mulch material itself determine its poor tensile strength, which makes it impossible to carry out mechanized mulching operations in agricultural areas dominated by mechanical operations. Therefore, by perfecting and improving the formula of the mulch film, increasing the tensile strength of the mulch film, and meeting the requirements of agricultural machinery operations, conditions can be created for the large-scale application of biodegradable mulch film.

Second, the rupture time and degradation controllability of the biodegradable mulch film are poor, and the function of increasing temperature and maintaining moisture is poor, and it is difficult to meet the growth needs of different climatic conditions and crops. Some of the existing biodegradable mulch products are broken and degraded prematurely, and the covering time is far below the safety period of crop mulching. It is difficult to guarantee the performance of its main functions such as increasing temperature, keeping moisture and inhibiting weeds, thus causing obstacles to the promotion of mulch.

Third, compared with ordinary PE mulch, high cost is an important limiting factor for the large-scale promotion and application of biodegradable mulch. Biodegradable mulch is inferior to PE mulch in terms of water retention and heat preservation, and various factors such as raw material cost, processing cost and production scale make the price of biodegradable mulch much higher than that of ordinary PE mulch.
