Аннотация В статье приведены теоретические обоснования введения в культуру привитого посадочного материала ореха грецкого. На данном этапе распространение этой культуры в производстве ограничивается отсутствием технологии выращивания привитого посадочного материала. В связи с этим появляется необходимость во введении этой технологии в производство. В статье обосновано и подкреплено расчетами использование в качестве маточных деревьев для выращивания подвоя ореха черного – насаждений, располагающихся в парковых зонах городских поселений.

Abstract The article presents theoretical grounds for introducing the grafted walnut seed material into the culture. At this stage, the spread of this crop in production is limited by the lack of technology for growing grafted planting material. In this connection, there is a need to introduce this technology into production. The article substantiates and is supported by calculations using as a fallopian tree for the cultivation of the walnut root of black - plantations located in the park zones of urban settlements. Keywords: Walnut, Walnut, Juglans nigra, the mother trees.   Introduction At the present stage of development of Walnut for southern agricultural zone of Russia, there are significant problems associated with laying of industrial plantations of walnut. Chief among them is a lack of quality planting material grafted this culture [1]. Trees grown from seedlings practically do not inherit the signs of the original maternal forms, and the culture of grafted walnut has not yet become traditional for domestic walnut breeding [2]. In addition, the existing plantations, because of the decline in their productive age, have ceased to provide guaranteed production of nuts. To bookmark the new walnut plantations of walnut intensive type [3] Often have to purchase expensive planting material abroad. In this case, as a rule, the peculiarities of the behavior of varieties offered by foreign nurseries in local conditions are not taken into account. The most optimal option for the renewal of walnut plantations in the southern zones of the Russian Federation is to provide local production of seedlings. When creating the production of walnut seedlings, there may also be a problem with the production of a slab material. One of the most promising rootstocks for Walnut walnut is black walnut [4]. Considering the fact that for today walnut walnut does not have clonal (vegetatively propagated) rootstocks, and the germinating nuts of walnuts are the same as those of black walnut. On the other hand, the walnut black as a rootstock has a number of advantages over the walnut seedlings. First, the stock is drier, hotter, and, more importantly, frost-resistant. Secondly, it is believed that trees grafted on a black nut before enter into a period of full fruiting. It is known that abroad, especially in northern walnut zones, gardeners prefer to use black walnut seedlings as a rootstock. The uterine-seed garden of this walnut assumes occupying large areas under it. As a consequence, it is not the rational use of agricultural areas. Instead, it is planned to plant seedlings as urban plantings, on alleys, in squares, etc. [5]. Such a solution will yield fruits of black walnut suitable for growing the rootstock when creating walnut seedlings. Research goal Determine the number of grafted planting materials for laying of industrial plantations of walnut in Russia these areas to bring this number up to the best able to meet the needs of Russians in the nuts. Determine the number of black walnut trees uterine necessary to ensure the nursery growers of walnut seedlings. Calculate the area of nut plantations of black masterbatches, which can be saved using the trees in urban plantings. The results of research To determine the area under walnut necessary for the development of the industry Walnut, should calculate the need for Russian citizens in the nuts. As of January 1, 2018 Russia's population is over 146 million people [6]. In the leading countries nut producers rate of walnut consumption per person per year is about 7.0 kg. If the calculations to apply the norms of consumption in our country, the annual demand of Russian citizens in walnuts would be: 146,880,432 people * 7 kg = 1,028,163 tons. Modern industrial plantations of walnut can produce crops within 1.4 tons of nuts per hectare. [7] Therefore, to meet the needs of the population each year should have square productive plants within: 1028 163.0 t ÷ 1,4 t /ha = 734.4 thousand ha We find the quantitative need for the grafted planting. To find this supply area based on the standard landing scheme 8x6 m [8, P. 18-30]: 10000 (m2 / ha) ÷ 48 (m2 / wood) = 208 trees / ha. However, plantations need timely update. The life span of the gardens, which can give optimal high yield, is 25 years [9, 86 p.]. After this period of time, they should be mired to bookmark new. For timely replenishment of plants that have lost their productivity, it is necessary to make a preliminary calculation of the volume of the fallopian plantations. We define as necessary seedlings required for laying plantings on areas that can satisfy demand in Russia Nuts: 734.4 thousand hectares * 208 seedlings / ha = 152 755 thousand seedlings. Then divide this amount for the period of operation of plants: 152,755 thousand seedlings ÷ 25 years = 6110 thousand seedlings. This number is both an indicator of the productivity of nurseries that produce seedlings grafted walnut. Modern technology seedling production, winter by grafting, allows to obtain 50% of the produced seedlings. Therefore, to meet the annual needs of nurseries gardeners should be performed: Taking into account that the seed germination of black walnut is within 75%, we find the number of seedlings that must be obtained for the production of the required material: . Walnut plantations are mainly grown in the southern regions of our country where the level of involvement of the territory, and so more than environmentally friendly standards. Often plowed land exceeds 80% [6]. If industrial plantations of walnut nuts can be successfully placed in the form of productive gardens themselves or as windbreak forest belts, it is unlikely that plantations of uterine-seed gardens will be placed by nursery farms. It should be noted, is also somewhat limiting factor for the production of graft nut culture. Our suggestion is that you can use as a rootstock seedlings of black walnut, which is to be consumed almost did not spread, but is highly decorative and is used in landscape construction of the forest-park and park areas of urban and rural settlements. If uterine walnut black plantations are placed in settlements, they will perform the function of upgrading the territory, and the nuts obtained from these trees can be used by nursery farms to lay out seedling seedlings for the subsequent production of seedlings of the grafted nut. This will allow integrating urban areas into agricultural production without harm to either party. Since ecological purity produced nuts for the production of seedlings it is not a limiting factor, that this proposal is very important in terms of how gardeners, nurserymen, and urban settlements. After all, did not take root grafting can then be used for growing trees directly walnut and black on a contractual basis transferred to urban greening, which supply the seed. If you plan to obtain the fruits of the black walnut in urban plantings must be borne in mind that factors such as exhaust gases, including carbon monoxide, dust, prevent photosynthesis and limit the productivity of the tree. Thus, the experimentally found in the area of Simferopol that of mature trees of black walnut in the city can make the average in the range of 600 nuts per year. Based on these data, calculate uterine trees need to obtain the necessary amount of ferrous nuts: In order to calculate the area under the given quantity uterine trees, trees must be given quantity divided by the maximum possible with the standard scheme landing. Conclusions:

1. Given that the production volume of a walnut in the Crimea, and Russia is not great, do not be afraid of the threat of overproduction. Also, it will promote the development of local production, aimed at import substitution policy.
2. To meet the needs of the Russian population in the nuts, you must have common areas within the gardens 4 thousand. Ha and produce at least 6.11 million annually seedlings.
3. Using urban planting black walnut, as the queen cells to seed cultivation can significantly optimize the use of the territory. Consequently we can avoid the waste of 130. 5 hectares of agricultural land.
