The invention belongs to the technical field of facility horticulture postharvest treatment, and particularly relates to a tomato postharvest quality regulation and control light supplementing system based on white light-metabolism key enzyme coupling activation and an application method thereof, and the tomato postharvest quality regulation and control light supplementing system comprises an enzyme activity targeting white light module, an enzyme activity feedback module and a fruit bearing regulation and control module. According to the postharvest tomato quality regulation and control light supplementing system based on white light-metabolic key enzyme coupling activation, a white light spectrum segmentation-key enzyme activity dynamic matching coupling mechanism is innovatively designed by combining the regulation and control rule of white light on the activity of key enzymes such as carotenoid synthetase and phenylpropane metabolic enzyme of tomato fruits; through an adjustable broad-spectrum white light source and an enzyme activity feedback module, directional accumulation of beneficial metabolites such as carotenoids and flavonoid compounds and efficient degradation of alkaloids are realized.

To provide a rain hood device capable of effectively performing rain shielding in tomato cultivation.SOLUTION: A rain hood device has an umbrella member 7 connected to an upper end part 6 of one or a plurality of support rods 5. The central portion of a lower surface part 11 of the umbrella member 7 is connected to upper end parts 6 of the support rods 5 erected on a planter 2. Fixing shaft parts 36 that detachably attach a portion 19 on an upper edge side of a rain hood sheet 17 having translucent property are provided in a protruded manner slightly inside the outer peripheral edge 16 for a lower peripheral edge portion 15 of the umbrella member 7. The rain hood sheet 17 is attached so as to surround an inside portion inside a lower peripheral edge 21 of the umbrella member 7 in a circumferential direction, and the portion 19 of the upper edge side is detachably fixed to a shaft part 36 by an engaging tool 55. Rainwater flown down on an upper surface part 9 of the umbrella member 7 flows down on an outer surface 26 of the rain hood sheet 17.SELECTED DRAWING: Figure 1

This invention provides an application of catalase and its encoding gene in improving the salt stress resistance of cucumber, belonging to the field of plant genetic engineering technology. In this invention, the gene CmoCAT2 from pumpkin is selected. An overexpression vector is constructed, and a pumpkin rootstock overexpressing the CmoCAT2 gene is created using Agrobacterium-mediated transformation. Using cucumber as the scion, it is verified that the mRNA of this gene can be transported long distances from the rootstock to the scion and can be translated locally within the scion, thus improving the salt stress resistance of cucumber. This method can cultivate salt-tolerant cucumber plants, adapting to the needs of cucurbit cultivation in saline-alkali land and saline-alkali soils in protected cultivation facilities.

The utility model relates to the technical field of ecological environment, in particular to a landscaping wall which comprises a U-shaped wall plate and a planting assembly, and the planting assembly comprises a cultivation structure, a transverse moving frame, a driving piece, two moving rods, two protection structures and a guiding piece. A driving piece on a transverse moving frame is controlled to drive two moving rods to drive two protection frames to get close to each other through guiding of a guiding piece, a buffering pad is used for buffering the impact force of the protection frames in the approaching process, then the two protection frames are buckled to cover a cultivation structure in a U-shaped wall plate, vegetation in the cultivation structure is protected through protection nets on the protection frames, and the cultivation structure is protected. And the protective net is provided with a plurality of through holes, so that ventilation of vegetation is facilitated, and the problems that according to an existing landscaping wall, due to the fact that a U-shaped wall plate is not provided with a protective structure, planted green plants are damaged in the intense thunderstorm weather, and then the attractiveness of the landscaping wall is affected are solved.
