The adjusting assembly is used for adjusting the water spraying rotation angle. According to the water spraying device, the motor drives the rotating rod to rotate, the rotating rod drives the sliding block to rotate, the sliding block drives the connecting block to swing, the connecting block drives the water pipe to swing, the effect of driving the water pipe to swing is achieved, and therefore the water spraying coverage range is widened.

The application discloses a cadmium tolerance related protein IbCSase of sweet potato and an encoding gene and application thereof, and belongs to the technical field of biotechnology, and particularly relates to the cadmium tolerance related protein IbCSase of sweet potato and the encoding gene and application thereof. The protein IbCSase is any one of the following: A1) a protein with an amino acid sequence as shown in SEQ ID No. 1; A2) a protein with more than 80% identity with the protein shown in A1) and the same function, which is obtained by substitution, deletion and / or addition of amino acid residues of the protein of A1); and A3) a fusion protein obtained by connecting a protein tag to the N terminal or / and C terminal of A1) or A2). By introducing the IbCSase encoding gene into wild type sweet potato, the tolerance of the plant to heavy metal cadmium can be improved, the IbCSase encoding gene can be applied to sweet potato breeding, and has wide application space and market prospect in the agricultural field.

The invention discloses a transcription factor gene IbMYB11 for regulating and controlling synthesis of sweet potato chlorogenic acid and application of the transcription factor gene IbMYB11, and belongs to the field of plant genetic engineering. Aiming at weak links of sweet potato chlorogenic acid synthesis regulation and control, the transcription factor IbMYB11 gene related to sweet potato chlorogenic acid synthesis regulation and control is cloned for the first time. The IbMYB11 belongs to an S7 subfamily, is positioned in a cell nucleus and has transcriptional activation activity, and accumulation of chlorogenic acid can be remarkably promoted by overexpressing the IbMYB11 gene in sweet potatoes. The sweet potato MYB transcription factor gene IbMYB11 provided by the invention can be used as an excellent gene resource, is widely applied to the field of plant genetic breeding, and has important significance for improving metabolism accumulation of chlorogenic acid substances of plants, especially for cultivating plant varieties with high chlorogenic acid content.

The invention discloses a deep processing and simple experiential preparation method of whole ficus tikoua bur fruits, which takes ficus tikoua bur fruits as raw materials, adopts a whole-course low-temperature additive-free pure physical process, synchronously prepares natural essential oil, water-soluble polysaccharide and dietary fiber, and realizes whole-fruit recycling and waste-free utilization. The method is mild in process and high in safety, completely retains aroma and active ingredients, is matched with a simple experience type processing flow, does not need professional equipment, is suitable for rural verbal travel, on-site manual experience and under-forest economic scenes, and can complete on-site extraction and manufacture of verbal and creative incense products within 2 hours. The method solves the problems that the ficus tikoua bur is low in resource utilization rate, high in deep processing difficulty and insufficient in experiential application, has double values of industrial production and travel experience, is complete in protection range and high in infringement threshold, and is suitable for large-scale popularization and patent authorization operation.

The application provides a integrated groove frame for shallow direction cultivation of Dioscorea alata L., and belongs to the technical field of yam planting. The device comprises a rectangular groove, a U-shaped groove and a vine traction pipe. The U-shaped groove is arranged in the rectangular groove and has a strip shape for guiding the directional growth of Dioscorea alata L. The vine traction pipe is arranged at the top of the rectangular groove and has an arc shape arranged at the top end and the end of the rectangular groove. The vine traction pipe is used for directional traction of the vines of Dioscorea alata L. The depth of the rectangular groove ranges from 25 cm to 30 cm. The groove frame has a depth ranging from 25 cm to 30 cm, which reduces the dependence of planting on the thickness of the soil layer. The vine traction pipe forms a continuous vine climbing path. After the vines of Dioscorea alata L. grow, the vines are guided to climb on the vine traction pipe, so that the vine leaves are uniformly distributed and mutual shading is avoided. The efficiency of vine photosynthesis is optimized, and the vines are prevented from lodging. When harvesting, the U-shaped groove is directly taken out, large-area soil turning is avoided, the damage to tubers and the destruction of soil structure are reduced, and the integrity of harvesting is improved.
