Description

(54) METHOD FOR STIMULATING GROWTH OF CUCUMBER PLANTS IN WATER CULTURE

bud formation phases, 2-6 mg of glugamic acid per liter of solution are added to the pigment solution, and the leaves are sprayed with an aqueous solution of the same acid and a calculation of 1.5-5 mg per plant at one time. The dose of acid for spraying and root feeding increases as plants grow. The acid concentration for foliar feeding is determined empirically, on the basis of the need to add the right amount of the substance and to prevent the solution from the leaves from dropping. C) planting is performed 4-6 times a week, root dressing is carried out together with the nutrient solution change (once a month -). In case of light exposure with glutamic acid, only lower, shaded leaves can be sprayed. Formation

the treatment of plants according to the proposed method prevents the lower leaves from drying out and the buds falling off during the transition from intense illumination to darkening,

for example, with prolonged cloudiness. The treatment of plants is finished in the phase of fruit ripening. To prepare a solution of glutamic acid should be at least once a week. On the I m square

cultivated plants during the growing season need about 500 mg of glutamic acid.,

Example. Verification method was carried out in the vegetative experience

in the aquatic culture of cucumber Hybrid-15O with a constant illumination of the middle and upper Russ leaves 3 thousand. lx (the stems were arranged horizontally). The data presented in table I.

Glutamic acid treatment table for cucumber productivity. Grown under illumination of 3 thousand lux

The data. I show that treatment of plant glutamic acid in low light significantly affects all the morphogenetic parameters of a plant, increasing, first of all, the proportion of roots in the total biological mass of the plant. Limiting the growth of leaves and especially of the stems with glutamic acid led to an acceleration of development and increased fruit production, in particular, the yield of fruits from plants increased by 24 grams or 38.7%. Fruits from srtcs plants were larger than the controls by 15.5%, had the best taste, had the best presentation. In the experiment, the plants began

to bear fruit 17 days earlier compared with the plants of the control variant .-, V ..-

Thus, glutamic acid to a certain extent can compensate for the lack of light, while using it for processing

roots and leaves increase the yield by 38.7%, improve its quality, accelerate fruiting for 17 days.

Pp m i e r 2. Plants were grown before harvest at half the dose of nitrogen by treating them with a solution of macronutrients and the proposed method.

A comparison of the proposed method with the known ones was carried out in pch: product chamber 5 .8 re with hybrid-150 cucumbers in 5 liter vessels under the same conditions of illumination intensity (3 thousand pc), photoperiod (13 h), temperature (2426 ° C) and root nutrition (nutritious mixture of hepyrigel). In addition to the above conditions, common to all the experiments in this series, the results of column No. 4 of Table 2 were obtained from spraying the plants with comparative data on the results and results of treatment of cucumbers with Rputamic acid obtained from the use of well-known methods at the beginning of blooming, phosphorus and potassium in the form of salts, included in Gelrigel diluted 4 times the nutrient mixture. However, neither the acceleration of fruit bearing nor the increase in yield compared with the control was obtained in the known methods (Table 2), Table 2

Claims (3)

Claim A method of stimulating the growth of cucumber plants in an aquatic culture, including top dressing plants, with the exception that, in order to increase yield and accelerate fruiting, plants under illumination 2.5-5 thousand liters top dressing is carried out from the formation phase 3S buds and until the fruit ripens by spraying the leaves with an aqueous solution of glutamic acid at the rate of 1.5-5 mg 'per plant at a time and additionally simultaneously treat the root system 40 subject plants with glutamic acid in an amount of 2 -6 mg per ligre of solution.
