Disclosed herein are multimodal polyethylene compositions, processes for making the same, and pipes made from the same. The multimodal polyethylene composition includes a first component and a second component. The composition according to embodiments disclosed herein has a density from 0.940 g / cm3 to 0.955 g / cm3; a melt index (I2) of at least 0.30 g / 10 min; and a Tp MW of greater than 145,000 g / mol at an elution temperature range of 90.0°C to 95.0°C. Pipes made from the composition can have a desirable balance of properties, including slow growth crack and hydrostatic pressure properties.

The utility model relates to the field of garden engineering, in particular to a sapling supporting frame for garden engineering, which comprises a bottom frame, height adjusting components are hinged on two sides of the bottom frame, spraying range adjusting components are arranged on the other two sides of the bottom frame, and fixing mechanisms are arranged at four corners of the bottom frame. The twisting piece is rotated to enable the arc-shaped supporting frame to ascend and descend, the size of the tree seedlings can be adjusted according to the growth condition of the tree seedlings, and therefore the use cost is reduced; by arranging the spraying range adjusting assembly, the spraying area can be adjusted according to the growth condition of the saplings, so that when the saplings grow and become high, the top area can be sprayed with water, the water in the top area cannot be reduced, and slow growth cannot be caused.

The invention belongs to the technical field of fungus culture and cultivation, and particularly relates to a wild Pleurotus ostreatus strain, a domestication and cultivation method and application of the wild Pleurotus ostreatus strain. The wild pleurotus ostreatus ZGCL25-8-11-11 is a high-temperature-resistant strain, the fruiting temperature ranges from 20 DEG C to 28 DEG C, sporocarp growing under the high-temperature condition is black gray, the sporocarp is subordinate, the single-bag yield of one flush of pleurotus ostreatus is at least 452 g, and the biological conversion rate is at least 85%. And the pleurotus ostreatus strain is dense in hypha and high in growth speed, so that the strain culture time in the cultivation material is shortened, the strain culture cost is reduced, and the defects that the existing pleurotus ostreatus strain is poor in high-temperature adaptability, low in growth speed and low in crude protein content are overcome.

This invention discloses a method for enhancing the drought resistance of bryophytes, relating to the field of environmental engineering technology. The method provided by this invention enables artificially cultivated bryophyte crusting materials, whose drought resistance needs to be enhanced, to passively receive induced VOCs to form a stress imprint, self-adjusting their physiological state to enhance drought resistance. This process consumes low material and energy costs, resulting in better plant performance under subsequent stress. It avoids the drawbacks of active methods, such as slow growth and high mortality rates after inoculation, thus exhibiting a greater survival advantage, higher propagation success rate, and greater stability. This method is effective not only during drought but also during rehydration. Furthermore, the method provided by this invention is simple and easy to implement.

The application discloses a sputtering growth method for sandwich deposition of AlN film, characterized in that a layer of AlN film A is first grown on a substrate by using a homoepitaxial target material with a slow growth speed, and then a layer of AlN film B is grown by using a heteroepitaxial target material with a fast growth speed, and the process is repeated to obtain the sandwich deposition of AlN film. The sandwich deposition of AlN film obtained by using the method has a smooth surface and a fast growth speed, and can be well compatible with a mass production and low cost preparation process. Meanwhile, the sandwich deposition of AlN film obtained by using the method is beneficial to release of recrystallization stress in subsequent high-temperature annealing, and can realize an AlN crystal film with low stress.

The invention discloses a method and a device for promoting early growth, rapid germination and robust growth of crops in a crop rotation area, belongs to the technical field of agricultural planting, and aims to achieve the purpose, the technical scheme adopted by the invention is as follows: the method for promoting early growth, rapid germination and robust growth of crops in the crop rotation area comprises the following steps: step 1, ridging and digging a foundation pit; the method comprises the following steps: ploughing a crop rotation paddy field, digging drainage channels, ridging, digging planting foundation pits at equal intervals, and airing for 10-15 days; 2, improvement treatment is conducted, specifically, hardened soil at the bottom of the foundation pit dug in the step 1 is smashed and scattered through a transplanting hole improvement device, solid or liquid fertilizer is synchronously applied, so that the soil in the foundation pit is loosened, and proper transplanting holes are obtained after the fertilizer, the matrix and the soil are evenly mixed; in order to solve the problems, the invention provides the method and the device for promoting early growth and rapid germination / robust growth of the crops in the crop rotation area, and the method and the device are used for solving the technical problems that the crops grow slowly and the yield is reduced easily due to soil hardening in the crop rotation area.
