Soilless cultivation is a kind of new technology of the arable farming to grow up in recent decades.Crop is not cultivation in soil
In, but the aqueous solution (nutrient solution) being planted in dissolved with minerals is inner；Or in certain cultivation matrix, crop is carried out with nutrient solution
Cultivation.As long as having certain cultivating device and having certain management measure, crop energy normal growth, and obtain high yield.Due to
Without using natural soil, and with nutrient solution pouring come cultivated crop, therefore referred to as soilless cultivation.
Nutrient solution is the successful key factor of soilless cultivation, what China's still large area use at present was developed decades ago
Hoagland, garden formula, the world Shan Qideng nutrient solution prescription, but cucumber is in actual production, frequently suffers from various lifes
Object and abiotic stress, abiotic stress mainly include salt stress, temperature stress, drought stress and heavy metal stress etc., seriously
Its normal growth and development is restricted, its yield and quality is influenced.And these common nutrient solutions cannot fully meet existing nothing at present
The needs of soil cultivation production, therefore, on the basis of kind, technology, mode improvement, by substrate culture cucumber supplementary functions
Type nutrient solution is particularly important to its resistance is improved, while having huge meaning on cucumber production.
GABA is otherwise known as γ-aminobutyric acid, is naturally occurring a kind of nonprotein amino acid or one in organism
The important intracellular signal molecule of kind, studies have shown that under normal circumstances, the GABA content in plant tissue is lower, about 0.03-2.00
μm ol/g FW, under a series of environment-stress, GABA can be raw to respond Stress on Plant by accumulating rapidly in plant
Inhibit caused by long development and injury, including hypoxemia, high temperature, arid and salt stress etc., but under adverse circumstance GABA synthesis meeting
It is suppressed, accumulation is limited, meets very much the growth demand of plant slowly.
