The article presents an analysis of prospects of development of mobile crushers for utilization ofrice straw using the method of assessing engineering and technical significance of inventions. The method consists of study of retrospective patent fund for previous 10-15 years which allows to make forecast of possible ways of technology development for the next 10-15 years. Based on obtained data of a patent, there was designed the graph of change in level of prospects of combine harvesters and mobile crushers by years of research. The presented results of forecast data showed that development of mobile crushers is a promising trend.

“…В послевоенные годы, когда рисоводство в стране бурно развивалось, именно такое зерно имели сорта 'Дубовский 129', 'Краснодарский 424' и 'Кубань 3', которые возделывались в СССР на большой площади более 50 лет. Они определили требования к комбайнам, очистительным машинам и перерабатывающим рис заводам, где оборудование было ориентировано именно на такой размер зерна (Zelensky, Zelenskaya, 2022). Сорта с более мелким зерном, даже высокоурожайные, до сих пор с трудом «приживаются» в российском производстве.…”

“…Если в европейских странах, США, Австралии погодные условия позволяют выращивать сорта риса, которые созревают через 140-150 дней после залива, то в России -не более 125 дней. Сорта с длительным вегетационным периодом здесь в отдельные годы не созревают из-за раннего похолодания осенью (Zelensky, Zelenskaya, 2022).…”

The main global trends in the breeding of rice cultivars and hybrids are higher plant productivity, adaptability to cultivation conditions, quality of products, and resistance to environmental stressors, including diseases.Efforts of leading breeding centers in the Philippines and China to further increase the rice yield are associated with a change in the plant morphotype: shorter plants with erectoid leaves and large panicles with a high number of grains.The International Rice Research Institute (IRRI) has developed rice cultivars that under favorable conditions in the tropical zone produce a grain yield of up to 10–11 t/ha, with Kecon = 0.5. A heterotic hybrid of rice was obtained in China with a yield of 13.9 t/ha; it has a new plant morphotype (New Plant Type) and a growing season of 163 days. The hybrid is classified as “super rice”.Modern breeding programs are aimed at producing cultivars of “Green Super Rice” using pedigree methods and backcrossing for introgression of target genes through DNA markers, QTL mapping, pyramiding, and recurrent selection.Russian breeders have traditionally produced rice cultivars adapted to local conditions, with a growing season of no more than 125 days. In the 1980s, a program was launched to develop a high-yielding rice cultivar with erectoid leaves for condensed planting. As a result of multiple stepwise hybridization and targeted selection, new source material with target traits of “super rice” was released. Cv. ‘Polyus-5’ with a new plant morphotype was obtained on its basis. This cultivar was included in the State Register and from 2023 approved for commercial production. During the field trials, ‘Polyus-5’ yielded a maximum of 1380 g/m2 over 120 days of the growing season, under the conditions of condensed sowing and increased mineral nutrition.

Patent analysis of design features of non-cereal crop choppers

The paper provides an overview of patent developments - mounted and trailed mobile choppers-straw spreaders. Their analysis is carried out and the shortcomings in the process of chopping and field distribution of the non-cereal part of rice crop are indicated. A design of PIRS-2-2 mobile trailed rice straw chopper is proposed, which is to eliminate the disadvantages inherent in the choppers designed for chopping cereal straw. The use of this machine will ensure the required quality of rice straw chopping and uniform distribution of check plots to a given width.
