Embodiment Construction

[0006] 1. The cultivation method to improve the low light resistance of greenhouse cucumbers is realized by spraying exogenous GSH technology on the leaves. Conditions such as the preparation method, preparation time, treatment method and time interval of exogenous GSH should be fully considered.

[0007] 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 one-ten-thousandth balance and add double distilled water to make 100mmol ·L -1 , Then dilute to 1 mmol·L -1 , 2mmol·L -1 , 5mmol·L -1 , 10mmol·L -1 , 20mmol·L -1 , All concentration solutions are ready for use (the mother liquor can be stored at 4 ℃, the storage time is limited to not forming crystals, 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 days. By spraying different concentrations of exogenous G...

Abstract

The invention discloses a cultivation method for improving low-light resistance of cucumbers under protected cultivation. The cultivation method is characterized in that different kinds of cucumbers are grown under an artificial low-light growth condition that is realized through a method of spraying GSH (reduced glutathione) on leaf surfaces of the cucumbers. An exogenous substance GSH with different concentrations is sprayed to the leaf surfaces and the optimal GSH concentration of 5 mmol.L<-1> is selected to obtain cucumber plants with strong low-light resistance, good physiological and biochemical indexes and good growth; the used cucumber materials are special varieties under protected cultivation provided by the Protected Horticulture Institute of Shanghai Academy of Agricultural Sciences. The cultivation method adopts a field plastic and multi-span greenhouse cultivation form. By means of spraying the exogenous substance GSH on the leaf surfaces, the problem that cucumbers under protected cultivation are relatively low in low-light resistance and weak in growth is effectively solved.

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 cloudy and rainy in a certain growth stage, which causes the light intensity of plants to weaken in a certain period, thereby affecting the formation of some organs and resulting in reduced yield; glutathione is a Mo...
