Netting House Application as a Facility for Rice (Oryza sativa L) Breeding Activities in Rice Fields
AbstrakPaddy is an annual plant that can adapt to waterlogged land. Rice is a self-pollinating plant (autogamy) which is a grammar group with a stem composed of several segments, fibrous roots, the presence of a tongue and leaf ear, and a collection of rice flowers (spikelets) called panicles. Cross-pollination can be done in several ways, namely artificial and natural pollination. Natural pollination is done with the help of wind, birds, and insects. The success of producing superior non-hybrid (Inbrid) rice by cross-pollination is complicated because rice is a self-pollinating plant. Artificial cross-pollination with the help of human hands will make it easier to produce new types of superior inbred rice. At the beginning of the establishment of the Seed Technology Study Program from 2009-2020, Seed Technology students carried out rice plant breeding practices in greenhouses. The available greenhouses are composed of glass walls and glass roofs. This can increase the temperature in the room. The optimum temperature for rice plant growth is 23°C-25°C. Meanwhile, the temperature in the greenhouse >30°C has an unfavorable impact on rice plants. The lack of success during the practice, namely the temperature in the greenhouse, is very high, reaching >30°C, thus increasing the transpiration rate in rice plants. As a result, rice plants experience stress due to a lack of water. This research aims to make a net house with a plastic roof (netting house) in the rice fields so that rice plants can grow optimally supported by temperature and rainfall. The netting house function can also protect rice plants from pests like rats, leafhoppers, bugs, and other pests. The benefits of this research are as a means for practicum and research activities for students, Education Laboratory Institutions (PLP), and lecturers to produce new varieties of rice.
