Abstract

Usage: in agriculture in feed production. SUMMARY OF THE INVENTION: white clover and corn are sown in alternating strips on silage. Melilot seeds are sown when the soil is heated to a depth of 5-7 cm to 6-8 ° C in a random manner in odd bands with a consumption rate of 7-8 million germinating seeds. Corn is sown at. heating the soil to a sowing depth of up to 12 15 ° C between 40-45 cm and a consumption rate of 0.19-0.24 million germinating seeds. Harvesting is carried out across the strips at the beginning of the yielding of clover and corn leaves. 1 s.p. crystals, 1 tab.

Description

The invention relates to the field of agriculture, in particular to crop production, and can be used to grow a maturing silage in fodder production.

The aim of the invention is to enrich the green mass of corn protein with clover and to achieve earlier mowing ripeness to free the field under the winter.

This goal is achieved by the fact that on one field at different times, due to the biology of crops, white clover is sown in maize, and white clover is sown in a row method on odd strips with a width that is a multiple of the width of the sowing unit when the soil is heated at a depth of 5-7 cm to 6-8 ° C with a sowing rate of 7-8 million germinating seeds per hectare, and maize is sown late in the unplanted strips broadly with 40-45 cm between rows with an increased sowing rate of 0.19- 0.24 million germinating grains per hectare with steady heating of the seed th

the soil layer is up to 12–15 ° С, and during harvesting, both crops are mowed across the stripes with the grass header at the beginning of leaf yielding simultaneously.

Example. Pre-select the field in which next winter will be placed winter. Then, as the previous crop is harvested, crop loosening is carried out, mineral fertilizers are applied in the required dose, deep loosening (plowing) is carried out, and as weeds and cultivations grow, cultivation and snapping occur. In winter, snow retention is carried out. In the spring, the soil is loosened with leveling pulleys with loops of the entire area and a line is hung up for straightness of sowing. Then, when the soil of the seed layer is heated to 6–8 cm, the odd bands are sown with a white clover with a seeding rate of 7–8 million germinating seeds per hectare. Sowing is carried out by an aggregate consisting of two sows, where an odd sowing (from left to right) sows a clover, and the second goes idle (without filling seeds

sweet clover). Thus, a through-batch sowing is obtained. The width of the strips will be equal to twice the capture of the sowing unit (4.2-7.2 m), taking into account the working capture of the cultivating cultivator. The depth of seeding of the clover seeds is set by 2-3 cm when sowing with a grain-grass seedling. do not roll crops. Subsequently, when the seed soil layer (8-10 cm) is warmed up to 12-15 ° С, the cultivator loosens even non-sown strips to the seed depth of 5-7 cm and the early-ripening hybrid maize is sown immediately with a sowing rate of 0, 19-0.24 million units of germinating seeds per hectare with a spacing of 40–45 cm between rows. Then, after sowing for 2-3 days, harrowing is carried out with light harrows and, when germination occurs, cultivating is cultivated if necessary. A month before the expected start of harvesting (August), chemical treatments of crops are stopped. At an earlier time they are carried out only in exceptional cases (with severe damage to aphid crops, with severe overgrowth of crops by weeds in the early stages of plant development, To harvest silage the masses begin when the leaves of sweet clover or corn wilt, and at that time corn also thickens when the crops are thickened due to the limited moisture reserves in the soil.

The data shown in the table show that corn sown between 40-45 cm between crops with a sowing rate of 0.19-0.24 million germinating seeds per hectare provided 20.5-22.7% more collection of green mass, dry matter, feed units, digestible protein and feed-protein units in comparison with the control - pure corn sown with an interval of 70 cm and a sowing rate of 0.06-0.07 million / ha. White clover exceeded the control (pure corn) by 1.44 c / ha for the collection of digestible protein. Strip-free coverless sowing of sweet clover and corn reduced the silage yield by 40 c / ha Compared with the control (376 c / ha), However, it provided 1.29 c / ha or

24.5% greater digestible protein harvest than control corn with an inter-space of 70 cm (5.26 c / ha). The yield of fodder protein units advantage

also retained for the strip cultivation of white sweet clover (sown by the seed method) with corn (sown with narrowed spaces between 40-45 cm) and an increased sowing rate of 0.19-0.24 million.

germinating grains per 1 ha. The main advantage of strip sowing is that the green mass for silage contains 41.1% more digestible protein in one feed unit than in the control variant - corn sown with 70 cm between rows and a sowing rate of 0.07 million. / ha. In the control variant, only 73 g of digestible protein per one feed unit.

The conditionally net income from the developed method is 30 rubles per hectare. The main thing is that it saves concentrated feed while balancing rations for digestible protein. In addition, the proposed method allows timely harvesting of the silage, which makes it possible to increase the yield of winter wheat by 2-4 kg / ha,
