Description

The invention relates to agriculture, in particular to the cultivation of maize under conditions of insufficient and unstable moisture.

The purpose of the invention is to improve the conditions of growth and development of plants, as well as increase the yield by maximizing the use of summer precipitation in conditions of insufficient and unstable moisture.

Fig. 1 shows a sectional profile of a section after passage of a gun to form ridges; Fig. 2 - the same, after the passage of the seed sowing tool in the ridges; fig. 3 - the same, after the passage for inter-row cultivation.

The method is carried out with the help of three tools, the first of which is intended for the formation of soil crests, the laying of crop residues between the crests and the application of fertilizers and chemical chemicals to the crests; the second implement is intended for sowing seeds into the crests of agricultural crops; the third tool is designed for inter-row processing of crops with simultaneous application of crop residues from the inter-row spaces to the ridges.

During the passage, the first implement carries out the formation of soil crests 1 at a given distance from one another, free from crop residues 2, laying of crop residues 2 in the intervals between the crests 1, as well as adding to the crests 1 of chemical chemicals (herbicides) 3 and fertilizers 4 .

During the passage, the second implement sows seeds 5 into the ridge and, if necessary, fertilizes and herbicides.

In prem passage, the third implement implements inter-row cultivation of crops after the emergence of shoots 6 and simultaneously with cultivation, application of crop residues 2 on the ridges 1

Example. The method was tested in field conditions on an area of 20 ha. The area of one case is 1 ha, the repetition of the experiment is 2 times. In the autumn, the predecessor was cleaned with crop residues spreading across the field.

Then they were removed from the narrow bands of the soil, the formation of soil ridges free of crop residues on these bands, and the straw was placed between the ridges according to a known method.

In the spring, corn seeds were sown in the ridges. Crop residues from between the rows, in the casting from a known method, were applied after the appearance of full sprouts during the first interrow cultivation of maize.

To kill weeds in the 3-4 leaf phase, the field was treated with herbicides. In the phase of 8-10 leaves, a second inter-cultivation with corn hilling was held

Corn was harvested in the phase of full ripeness of the grain.

The yield of corn grain by a known method averaged 44.9 centners per hectare, and according to the proposed method, 51.4 centners per hectare.

Preservation of vegetable mulch between corn spacing and on the ridges before harvesting contributes to a better supply of moisture to plants, especially in the critical period of their development,

The use of the ridges allows you to start planting corn earlier and, consequently, start harvesting it, thus creating conditions for the timely and high-quality preparation of the soil for sowing of winter grains.

The formation of ridges without embedding plant residues in their body improves the dynamics of the emergence of seedlings, increasing the field germination of seeds.

On the ridge without plant residues, the soil warms up faster, the seeds of agricultural crops, in particular maize, do not grow moldy and are not damaged much.

pests and diseases, there is no weakening of plants. As a result, crops of optimum thickness are obtained, no increase in the seeding rate is required, and seed material is saved.

It has a fuller effect on weeds and herbicides due to good heating of the soil, it is not bound by plant residues, due to which weed growth is more inhibited, crops

in rows get cleaner. Nitrogen binding by plant residues does not occur, therefore plants are better supplied with them.

The method can be applied in the cultivation of high-stemmed wide-row row crops in areas of the country with insufficient and unstable moisture, in areas with the manifestation of water and wind erosion, as a means of combating

deflation and destruction of soil by thawed and storm waters.
