چکیده

В процессе селекционно-семеноводческой работы с семенными растениями необходимо проводить ряд мероприятий (осмотр, подвязка растений, выбраковка не типичных и ослабленных изоляция). Особенно при создании «чистого» линейного материала (стерильных фертильных). Нужно внимательно подходить к этому вопросу. Чаще выбраковку. При традиционной схеме посадки 70 см неудобно выполнять данные мероприятия, так как в момент цветения растения достигают более 100 см. Происходит частичное смыкание рядов. уборки семян ряды смыкаются, для получения «чистых» линий такое допустимо. Цель исследований – разработка технологического приема подборе схемы размножении селекционном оригинальном семеноводстве моркови столовой. Исследования проводили 2019–2021 годах. Опыты закладывали условиях пленочной теплицы на территории селекционного центра агрофирмы «Поиск» (Раменский район Московской области). Корнеплоды высаживали вручную по схемам шагом 20 см: (контроль), 96 + см, 112 Подбор схем целью оптимизации работ уходу за растениями, проведения сортопрочисток. Площадь учетной делянки 14,7 м2, двукратная повторность. Объект исследования: семенные столовой (690 690 П). Густота стояния растений зависимости от опыта изменялась практически 2 раза: 4,5 до 7,1 8,6 шт/м2. привел удобству работы, но небольшому росту продуктивности незначительной потере урожайности Схема отличалась также убылью данным признакам. По посевным качествам семена во всех вариантах были идентичными (82–91,3% всхожесть). In the process of seed breeding work with plants, it is necessary to carry out a number measures (inspection, garter culling non-typical and weakened isolation). Especially when creating «pure» linear material (sterile fertile). We need approach this issue carefully. Culling should be carried more often. With traditional planting scheme cm, inconvenient these measures, since at time flowering plants reach than cm. There partial closure rows. At harvesting, rows close, not allowed obtain «clean» lines. The purpose research develop technological technique in selection for propagation original production table carrots. studies were conducted 2019–2021. experiments laid film greenhouse on territory center agrofirm «Poisk» (Ramensky district Moscow region). Root crops planted manually according schemes step cm: cm (control), was order optimize care carrying variety cleaning. area accounting plot 14.7 m2, double repetition. object research: carrot lines dining room B P). density standing depending experiment, changed almost times: from 4.5 7.1 8.6 pcs /m2. carrots led ease operation, but slight increase productivity loss yield under scheme. also distinguished by decrease signs. terms sowing qualities, seeds all variants identical (82–91.3% germination).

The Economics of Planting Rights in Wine Production

Almost half of the world’s vineyards are in the EU and the EU produces around 60% of the world’s wine. The EU is also the world’s most regulated wine market. In 2007, the European Union decided on a major reform of its wine policy, the so-called Common Market Organization (CMO) for wine. A crucial element was the abolishment of a system of planting rights to regulate planting of vineyards in th...
