Description

The invention relates to agriculture and can be used for growing henna using the hydroponic method.

A nutrient solution containing mineral salts is used for soilless cultivation of plants.

 However, studies have shown that the best solution for henna is a solution with a reduced dose of nitrogen, phosphorus, potassium, which is ensured by a decrease in the concentrations of the corresponding salts.

The closest in technical essence and the achieved result is

hydroponic spike solution

However, the productivity of henna grown using this solution is relatively low.

The purpose of the invention is to increase the productivity of henna.

This aim is achieved in that the nutrient solution for hydroponic You are a capacity- henna comprising potassium nitrate, ammonium nitrate, ammonium sulfate, potassium sulfate, phosphoric acid, ferrous sulphate, boric acid, manganese sulfate, sernokis- luyu copper, zinc sulfate, cobalt nitrate , potassium iodide, additionally contains dimethyl sulfoxide in the following ratio of components, mg / l:

The order of the components corresponds to the written order.

All components are introduced into the flask, topped up with water to 1 l. The solution is filtered through a cotton-gauze filter.

Under conditions of open hydroponics, henna is cultivated as an annual culture by seedling. In springtime, the seedlings grown in the greenhouse are transported in spring to open gravel-filled areas. The nutrient solution is supplied with an automatically operating food unit, feeding it in the spring 1-2 times, in the summer 2-3 times and in the autumn 1 time a day. The control are simultaneous planting, for which they use a known nutrient solution.

Example 2-8. Preparing the nutrient solution of example 1. The ingredients are used in the amounts shown in Table 1.

Indicators of henna productivity and the effect of the composition of the nutrient solution on henna productivity are shown in Table 2,

As follows from the experimental data, the use of dimethyl sulfoxide in the amount of 10-100 mg / l (examples 1-5) in the proposed solution contributes to the rapid growth of henna, increase in productivity. An increase in the concentration of DMSO above the specified limit (Example 6) adversely affects the sheet productivity and dye yield, since high concentrations result in the appearance of leaf necrosis. A decrease in the DMSO concentration below the specified limit (Example 7) does not have a positive effect performance indicators. In addition, a further reduction in the number of components is impractical because it does not affect the achievement of the goal (Example 8).
