Description

FIELD: agriculture. SUBSTANCE: invention relates to methods for growing high protein feed mixtures of various species composition.

The predominant area of its use is irrigated agriculture.

The aim of the invention is to increase yield and quality.

The goal is achieved by the fact that after harvesting the cereal-sainfoin mixtures, corn, Sudanese grass or their mixtures are planted in the stubble at a rate of the last 0.3 and 3.5 million / ha.

Sainfoin was sown on August 18, 1989 with a sowing rate of 5.6 million seeds per hectare. Mass seedlings of sainfoin appeared 12 Sep. Sowings of winter rye Harbkovsk 55, triticale Odessa fodder, winter wheat Dneprovsk 846 were carried out directly in sainfoin 18 September at a rate of 3.5 million seeds per hectare of grain sowing.

Full shoots of winter crops are marked on September 22 In early spring, nitrogen-fertilizing of 1.5 c / ha of ammonium nitrate was carried out on thawed frozen soil. The resumption of vegetation in 1990 was noted on February 24, with an average long-term date of March 21. The winter tube went out on March 24, the beginning of wheat rye and the triticale started on April 23-27. The beginning of winter wheat ears and mass budding is a single sainfoin flowering - 15 ma.

Pure sainfoin crops during harvesting in the second decade of ma provided in the first mowing 342 kg / ha of green mass, the content of digestible protein per 1 unit - 176 g, which is 1.56 times higher than the zootechnical norm. When using pure sainfoin inoculations for green food, protein is consumed in pairs, while sugars are lacking in such food, and therefore the zootechnical norm for the sugar-protein ratio is not maintained and is 0.3 (Table 1).

According to the data in Table 1, the highest yield of green mass (406 kg / ha) was obtained by sowing winter triticale in sainfoin. The share of sainfoin is 49 kg / ha. Balance

1 unit digestible protein was 118 g, sugar-protein ratio -11.

When sowing winter wheat in sainfoin, the total yield of green mass was 368 kg / ha, but the weight of sainfoin in it was the highest and amounted to 121 kg / ha. The content of digestible protein per 1 unit increased to 147 ha, the sugar-protein ratio was 1.5.

After harvesting pure sainfoin and its mixtures with winter crops,

2c / ha of ammonium nitrate, carried out vegetative irrigation at a rate of 600 m / ha and without preliminary preparation with the SZS-2,1 rural village, corn was planted (Krasnodar 400),

Sudanese grass (Chernomorsk) and a mixture of corn with Sudanese grass. Sowing was carried out directly in the stubble. The seeding rate of corn is 0.3 million, Sudan grass 3, 5 million / ha.

On the crops, 4 vegetative irrigation irrigation rates of 2400 m3 / ha were carried out.

The accumulation of green mass was most intense in June. The increase in green mass as of July 11 for corn amounted to 1783, Sudan grass - 1757 g / m2. When sown in stubble (sainfoin + winter wheat), the yield accumulation in corn was 1700, Sudan grass

5 - 1640 g / m7.

In the third decade of June, the highest biomass accumulation (3300-3600 g / m2) was recorded on Sudan grass crops at a height of 175-190 cm.

0 The harvest of Sudanese grass in the second mowing was less intense and, as of 18 September, amounted to 1300-1400 g / m2 with a height of grass of 135-140 cm.

5 Slow corn growth has contributed to weed crops, especially nightshade. Weeds delayed sainfoin growth, and its share in the crop was insignificant - 4–11 c / ha.

0 Therefore, the feed unit of the green mass of corn sown in sainfoin and sainfoin + cereals is unbalanced in digestible protein (Table 2).

Highest productivity

5 (400-427 kg / ha of green mass) provided crops for Sudanese grass.

The sainfoin aftermath in this crop was 38–55 kg / ha. The participation of sainfoin in green feed provided a balance

0 feed units for digestible protein. The green mass of the Sudan mowing grass was notable for its low nitrate content - 47-48 mg per kilogram of feed.

5 The total water consumption of the slant crops was 3100-3200 m / ha. water consumption coefficient - 75-79 m / t. The total productivity of fodder irrigated hectare when grown in the first crop of sainfoin (summer sowing season) and sainfoin with sowing winter crops and seed corn, Sudan grass and a mixture of corn and Sudan grass amounted to 573-782 cent green mass, 107-149 cent feed units and 12.0 - 20.9 c / ha of digestible protein. The highest yield of green mass (768–784 kg / ha) was achieved by sowing in combination with sainfoin with sowing of winter wheat and sainfoin with sowing of triticale + cutting by seedlings of Sudanese grass mixed with corn (Table 3).

Intermediate sainfoin sowing in combination with yielding sowing of Sudanese grass provided the highest yield of digestible protein - 20.9 c / ha.

Thus, the research data of the fodder crop department of the Ukrainian Scientific Research Institute of Irrigated Agriculture for 1989-1990 indicate the possibility of obtaining high-quality fodder balanced for digestible protein, sugars and other nutrients, sainfoin with sowing of winter crops and slaughter in winter stubble sainfoin of Sudanese grass or its mixture with corn.

The invention solves the problem of increasing the yield and quality of feed mixtures to create a solid fodder base and raising livestock.

an integral part of forage crop cultivation technology, which makes it possible to obtain up to 166 ked units on irrigation
