Abstract

The invention relates to agriculture and can be used when sowing cultivated crops such as corn, sunflower, beet, vegetable and melon. The aim of the invention is to reduce weeding costs. This is achieved by cutting the groove to a wet layer of soil, but not less than the sowing depth up to two protective zones. Seeds are placed in the middle to the bottom of the groove with compaction and covered with a layer of dry, loose soil removed from the surface to the required depth of sowing 3 silt

Description

The invention relates to agriculture, in particular, to the cultivation of the drinking cult / p such kchk ukrue9 sunflower beet vegetable and melon

The purpose of the invention is to reduce the cost of nl weeding.

Fig. 1 shows two options for cutting the sowing grooves to the depth of the moist soil layer in Fig. 2 — a method for laying and embedding seeds in Fig. 3 — a method of post-sowing cultivation.

The method is carried out as follows.

Before sowing, when crafting guide slits or simultaneously with sowing, grooves are cut in the wake of future rows. Two options are possible. The depth of the groove is equal to the sowing depth (variant I, Fig. 1) if the seeds fall into the wet soil layer, i.e. layer b is less than the sowing depth hni hb hn The wet layer is the soil layer that is optimal for

sprouting moisture If the wet soil layer is located below the depth of sowing, the groove is made to the depth of the upper boundary of the wet layer L e te b hn (option II fi (1) Vorotdka rectangular or trapezoidal shape with a flat bottom width of at least two protective zones To the bottom in the middle of the grooves are laid the seeds with compaction ensuring good contact of the seeds with wet soil. Simultaneously with the sowing, the groove is filled with dry loose soil taken from the surface of the floor (Fig. 2). The height of the backfill layer should correspond to the depth of . Eva In the first embodiment, the furrow is filled completely (embodiment 2), and in the second - not completely (variant II of Figure 2) only at the sowing depth

In view of the fact that the seeds fall into the wet soil, they quickly germinate. In the bedded a (fig. 3), the soil is dry, therefore weeds do not germinate in it And those weeds that began to germinate with moisture

layer, trimmed when cutting the grooves. Therefore, the cultivated plant springs up on a clean background, and after the shoots of weeds emerged from the bottom of the furrow, b fall asleep during cultivation (fig. 3) and they die.

Example. Conducted with pre-seed irrigation at a rate of 600 m / ha. After drying, the upper layer of soil 3-4 cm thick makes gaps and simultaneously cut three grooves 4-5 cm deep. The width of the groove is equal to the width of two protective zones, see. The grooves are cut with PPR-5.6 fixtures (cutting them to width 12). cm). The roller of the soil from the grooves is brought to one side. Watermelon sowing is carried out in the middle of the groove to the bottom of the HRC-BM. The opener is not spring loaded, therefore the seeds are placed on the bottom of the groove to a depth of 1.5 cm. The roller of the section compacts the sowing zone and ensures good contact of the seeds with the soil. Mounted on the back of each seed section is a zagort, scrubbing the surface of the upper dry layer of soil 2-3 cm thick and filling it with a groove. In front of the door, there is a support wheel of the cultivator section. This ensures good crumbling of the soil in the cleaned strip and a clear keeping of the depth of the stroke of the locker. Therefore, the soil is fed into the grooves. If necessary, increased loosening of the soil instead of a zagorucha put weeding rotor. He actively crushes the soil and covers it with a groove. After filling the groove, the depth of the seed is 5–6 cm. The soil is tucked away from the side of the groove free of the roller (from a 20 cm wide strip).

On the sixth - seventh day after gtosse, amid shoots of watermelons appear on the background clean of weeds. Field germination is higher than 70%. Weeding in the initial period is excluded. Cultivations are carried out without breaking the grooves. Here is the dry soil

the width of the grooves must be at least two protective zones (one protective zone on each side of the row).

The advantages of the proposed seeding

the following.

The method always ensures sowing of seeds in a moist soil layer, while maintaining the optimum sowing depth. The seeds are covered with a dry, loose layer of soil,

excluding evaporation of moisture, ensuring its preservation in the soil directly in the zone of the row. When cutting the grooves, the surface of the soil under the surface is aligned with the crop, which stabilizes

sowing depth. At the same time, weed shoots are grown by this time. The seedlings of the cultivated plant are obtained without post-sowing irrigation (in the irrigated zone), which is very important: a soil crust does not form and weeds are not provoked. In the dry soil above the seeds, weeds do not germinate. Therefore, the seedlings of the cultivated plant appear on a background free from weeds. Manual weeding is excluded in the initial vegetation stage without the use of herbicides.
