Scientific development for the cooling temperature of the concentrated dairy product with sugar and malt extract

УДК 637.345

A two-stage cooling method of the concentrated dairy product with sugar and malt extract is calculated in the article. The given method is based on the principle that cooling rate must outpace lactose crystallization rate. As a result of a pilot check it was found that two-stage cooling method can improve the quality of a finished product compared to a conventional one due to reducing an average size of lactose crystals.

Method of Determining Priority Investment Sectors for Milk Processing Enterprises

УДК 658.152

Russian economy recovery from a deep systemic crisis is possible only by means of production investment expansion. However, receiving sufficient investment does not guarantee its effective use by the company. The present situation is the following: on the one hand an enterprise is in a dire need for investment, and on the other hand many of them are unable to ensure its effective use because of no or insufficient investment management elaboration. The article gives the algorithm of investment decision-making concerning the selection of priority investment sectors under limited investment resources. Priority sectors for real investment are identified on the basis of analysis of efficiency of production and financial resource use by the Vologda region milk processing enterprises.

The impact of variability of the type of Siberian cedar by seed scale apophysis on the seed peel firmness

УДК 630*161:575.21:581.48

The seed peel firmness of Siberian cedar morphological forms (by seed scale apophysis) has been studies. The existence of differences on the seed peel firmness indicators between the forms is theoretically based by the nutcracker’s activity. The results of the experiments prove the given assumption. It is shown that nuts from the cones with plain apophysis type require the relatively less maximum power and tension, but more time on their cracking. To use the seeds of the given morphological trees’ forms is prospective for the production of cedar kernel. It is offered to select the types with plain seed peel apophysis type for the selection on the market qualities of the cedar nut.

Influence of thinning out and nitrogen fertilizers on photosynthesis and growth of spruce in birch forests of myrtillus type

УДК 630*232.322.4 (045)

The effect of different nitrogen doses and cutting on the rate of physiological and growth processes has been studied in birch forests of blueberry type in taiga zone. It has been established that nitrogen has got little effect on the vitality and growth of spruce in mature birch forests because of the light lack. In thinned stands the nitrogen increases the rate of photosynthesis twofold, activates processes associated with the accumulation and subsequent outflow of carbon metabolites from the needles. The result of this nitrogen action is the intensification of growth processes. The most favorable conditions for the growth of the spruce undergrowth in birch forests of blueberry type in taiga zone are formed at a cutting intensity of 50% and nitrogen introduction of 180 kg / ha due to primary nutrient. Further thinning of forest stands and introduction of increased amounts of nitrogen have no significant impact on the life and growth of young spruce and only leads to more expensive works.

Formation of steadily productive annual mixed sowings based on optimization of mineral nutrition

УДК 633.352.1+633.162+633.13:631.81(470.331)

Complex researches have been conducted in the Tver region on sod medium podzolic sandy loam well-cultivated soil. We have studied implementation of crop yield programmable levels by means of vetch-barley-oats mixtures different in composition. The advantage of their cultivation on grain-and-hay has been revealed, when the program both at the background of 2.5 thous. feed unit /ha and 5.0 thous. feed unit /ha on all variants of mixed crops was exceeded. Program has been carried out only at the programming level on 2.5 thous. feed unit / ha when growing mixtures for grain. The vetch-barley-oats mixtures have the biggest response to mineral fertilizers when programming. The mixtures had a ratio: at cultivation on grain-and-hay 20 % : 40 % : 60 % (on the background 2.5 thous. feed unit /ha) and 40 % : 60 % : 20 % (on the background 5.0 thous. feed unit /ha), for grain 40 % : 40 % : 40 % (on both backgrounds). Foliar application by microbiological fertilizer Baikal EM1 in the tillering phase of Poaceae components has increased the percentage of program implementation, regardless on a kind of received production, as well as it has increased collecting of digestible protein and output of exchange energy. The positive effect from the calculated doses of mineral fertilizers and spraying by Baikal EM1 has been achieved by improving the indicators of photosynthetic activity (leaf area, photosynthetic potential of seeding, net photosynthetic productivity, efficiency of photosynthetic active radiation) and the direction of the productional process on yield.
