Description

n - by 20% and rye - by 15-30%.

The proposed formulation can treat plants, seeds, or soil into which seeds are planted.

Example 1. The test is carried out in several Mitscherlnha vessels with loamy soil, into which 1 g of nitrogen is introduced. In the form of ammonium nitrate, 1.2 g of phosphoric anhydride in the form of secondary calcium phosphate, 0.8 g of KzO in vde K2SO4, 0, 5 g MgO as MgSOi. TNGO.

In each tank, 20 grains of wheat 1 are sown every day; they are poured with distilled water in an amount of 50% of the maximum water capacity.

On the day of the appearance of vegetative plants, the latter are treated with 7 ml of an aqueous solution of the proposed agent.

The height of the plants at the time of full ripening under greenhouse conditions relative to the control experiment (without treatment with the preparation) is shown in Table. one.

A p II V e h a and e. The limiting difference is 5%.

Example 2. In order to determine the effectiveness of the proposed formulation, field wheat is treated in field conditions.

To do this, they use 10 m.

250 kg of wheat are planted per hectare of land, in which, along with phosphorus-potassium fertilizer, nitrogen is introduced in the amount of 140 / cg per 1 hectare.

EXAMPLE E. The limiting difference is 5%.

 100% - 105 cm. 100% -35.1 c ha.

By the time of full maturity, the height of plants, the yield and the degree of lodging are determined.

The degree of fumbling is assessed by a 9-point system: 1 - vertical field; 9 - full lodging.

The results of the determinations are presented in table. 2

table 2

Example 3. To determine efficacy in the field, barley is treated with an aqueous solution of the proposed agent.

As a test material, they use 10 m squares.

130 kg / ha of sowing is planted in the soil. Probability of error is 0.05;

Note. 0.01; 0.0001.

Example 4. To determine the effectiveness of the proposed agent with respect to the summer variety of rye, treatment with the composition of 2,3-dichloroisobutyric acid (3 kg1 hectare) + + (2-chloroethyl) -trimethylammonium chloride Note: From the measure in the stage From the tab. 4 shows that the proposed tool gives a reduction in the length of the stem with

material with the preliminary introduction of phosphorus-potassium and nitrogen fertilizers into it.

By the time of ripening, the length of the stem (100% - 90.7 cm) and yield (100% -43.7 1 {/ y) are determined.

The results are presented in table. 3

(I KAlea) are carried out according to example 1. In each tank (there are only three), 25 units of culture are sown.

The resulting results are presented in Table. four.

Table 4, the formation of the third sheet; its simultaneous thickening and without a decrease in yield.
