Abstract

The invention relates to agriculture and can be used in the cultivation of agricultural crops such as mulberry. The aim of the invention is to reduce the labor costs of weeding, saving irrigation, water and improving the conditions for the development of plants and the mechanized treatment of crops during irrigation. First, grooves are cut into the field, which are covered with a waterproof film, then two layers of soil are stuck in them — the lower fertile and the upper without seed plants, and the seeds of cultivated plants are sown last. For irrigation, a groove is cut into the side of the seed row, within the isolated part, 1 tab., 1 sludge. (L

The invention relates to agriculture, in particular to the cultivation of various crop crops, and can be used in the mechanized sowing of mulberry.

The purpose of the invention is to reduce labor costs for weeding, save irrigation water and improve the conditions for the development of plants and mechanized treatment of crops during irrigation.

The drawing shows the groove with sprouted seeds

The method of sowing agricultural crops is carried out using known devices (a bucket trencher, a film stacker, a soil picker) or a device that performs trenching, laying of the film, crushing the soil in two layers and sowing with the irrigation groove squeezing. The method is characterized by the following operations.

They dig a groove (the groove profile can be triangular or rectangular) into which the film 1 is laid and covered with two layers 2 and 3 of the soil. Bottom layer 2 is fertile

The table shows the results of a comparative experimental verification of mulberry sowings: by a known method with filling seeds in the soil, dug out when cutting the grooves. The thickness (depth) and width of the soil through soil or rotted soil layer 2 must have corresponding residues and, in terms of size, offer a root systemic method.

For example, for mulberry, a sufficient depth of layer 2 of the soil is 25 cm, and a strip width of 40 cm “on the fertile bottom layer 2 of the soil, lay the top layer 3 of the soil without weed seeds about

The top layer 3 of the soil serves to delay the germination of seeds of first plants placed in the fertile layer 2 o After that, the seeds of cultivated plants, such as mulberry, are sown in the top layer 3. -70 mm.

In springtime, the ambient temperature when sowing mulberries is insufficient for heating the soil layer 3 of a given thickness. When sowing in May-June, the ambient temperature is considerable, therefore, at late sowing periods, soil layer 3 should be increased to 120 mm to inhibit weeds (see table) about

The table shows the results of a comparative experimental verification of mulberry crops: according to a known method, with soil being plowed into the groove with soil or rotted plant remains and according to the proposed method.

The known sowing method was adopted as a control. In the control sowing, mulberry seeds were sown in an open groove; they were sewn with a layer of soil (option I) or rotted cotton plant debris (option II).

Mulberry seeds were planted in the same field using the proposed method.

Polyethylene film tapes were laid into the furrows opened at a depth of 25 cm, the edges of which were fixed on the floor with earth rollers. Then, layer 2 of the soil extracted from the furrow 18–20 cm high was poured onto the film, and another layer of sterile soil 3 . without seed and weed plants. Sterile soil can be prepared by thermal or electrical treatment, for example, with a flame cultivator or an electric sterilizer. In the experiment, the soil extracted from the arable layer, which was not subjected to thermal or electrical treatment, was used as a sterile soil. After zeshka furrow soil in layer 3. sown seeds 4 mulberries and cut irrigation grooves 5

The irrigation groove 5 may be made on the edge or in the center of the top layer 3 of the soil, but within the laid film 1. Film 1 when irrigating as a tray holds water in

irrigation water. The width of the band with is chosen depending on the moisture consumption of the agricultural crop, with d, and with d.

The d strip when watered is not wet. Therefore, it is possible to pass through the wheels of tilled units for fertilizer application and control of agricultural pest damage.

Seeds 4 mulberries are buried in layer 3 of the soil to a depth of 3-5 mm. Za0

those on the irrigation groove 5 supply water for 2 months. for continuous soil moistening. Such a prolonged supply of water to the groove 5 is determined by the peculiarities of the development of mulberry, the seedlings of which appear 12-1-4 days after sowing. After the emergence of mulberry seedlings for 2 months, only the root system develops, while the outer part of the plant remains practically unchanged. When cessation of moisture on the surface forms a soil crust and tender sprouts die, therefore continuous moisture creates conditions for the mulberry to live. But enhanced hydration with existing methods of crop improvement creates favorable conditions for weed growth. According to the proposed method of sowing seeds and agricultural crops, the upper sterile soil layer 3 prevents the germination of weeds. In this regard, labor costs for weeding, cultivation and other activities are reduced.

Claims (1)

30 claims The method of sowing seeds, including cutting furrows, laying the seeds and filling them with soil, is different in that in order to reduce the labor costs of weeding, save irrigation water and improve the conditions for the development of plants and mechanized processing of crops during irrigation, walls and the bottom of the furrow is covered with a water-impermeable film, then two fir trees of the soil are poured into the furrow, the lower one is a fertile and upper soil free of seeds, while the seeds of cultivated plants are laid in the upper layer and the irrigation groove is made.
