Embodiment Construction

[0008] 1. The cultivation method for improving the low-light resistance of facility cucumbers is realized by spraying exogenous GSH technology on the leaves. The preparation method, preparation time, treatment method, time interval and other conditions of exogenous GSH should be fully considered.

[0009] The GSH used in this patent is produced by Sinopharm Chemical Reagent Co., Ltd. When preparing the concentration of exogenous GSH, weigh it with a balance of one ten-thousandth, and add double distilled water to make it 100mmol L -1 stock solution, and then diluted to 1 mmol·L -1 , 2mmol·L -1 , 5mmol·L -1 , 10mmol·L -1 , 20mmol·L -1 , all concentrations of solutions are prepared and used immediately (the mother liquor can be stored at 4 ℃, and the storage time is limited to no crystal formation. When crystals appear in the solution, it must be reconfigured); in order to ensure the stability of the treatment concentration, every 3- Exogenous GSH was sprayed once every 5 ...

Abstract

The invention is a cultivation method for improving low-light tolerance of facility cucumbers, which is characterized in that: the different types of cucumbers are given artificial low-light conditions to grow, and the method is realized by spraying GSH (reduced glutathione) on the leaves. By spraying different concentrations of exogenous substance GSH on the foliage, the optimal GSH concentration is selected to obtain cucumber plants with strong low light resistance, physiological and biochemical indicators, and good growth vigor. The optimal concentration selected is: 5mmol L‑ 1; The cucumber material used is a facility-specific variety provided by the Institute of Facility Horticulture, Shanghai Academy of Agricultural Sciences. The cultivation form used is field plastic multi-span greenhouse cultivation. The problem of weak resistance to low light and weak growth vigor of facility cucumbers is effectively solved by spraying the exogenous substance GSH on the leaves.

Description

technical field [0001] The invention relates to a cultivation technique for improving low-light resistance of cucumbers, in particular to a cultivation technique for improving low-light resistance of cucumbers by spraying exogenous substance GSH on leaves. Background technique [0002] In recent years, facility vegetables have developed rapidly, and successive years of production have led to the aging of facility light-transmitting covering materials and the accumulation of dust, which reduces the light transmittance of facilities and seriously affects the quality and yield of vegetables and the sustainable development of facility production. At the same time, in different growth stages of plants, the leaves often shade each other due to close planting, or it is overcast and rainy in a certain growth stage, which causes the light intensity of the plants to weaken in a certain period, thereby affecting the formation of some organs and resulting in reduced yield. [0003] Glut...
