What is the difference between duck rice and ordinary rice?
Duck rice is the short name for a planting model of organic rice, in which ducklings 20 days old are released into rice paddies about 15 days after transplanting, and the ducks and the rice grow together and complement each other. So what is the difference between duck rice grown this way and ordinary rice? Friends who do not know can take a look together.
1. The difference between duck rice and ordinary rice
The fertilizer for duck rice comes from duck droppings, and the work of pest control and weeding is all done by the ducks, so there is no pesticide residue. The ducks moving around in the field promote the rice's absorption of nutrients from the soil, with one harvest a year, one crop of rice and one batch of ducks a year.
The fertilizer for ordinary rice mainly comes from chemical fertilizers, and pest control and weeding rely on pesticides and herbicides, so there will be a little chemical residue, the rice cannot fully absorb the nutrients in the soil, and there are two or three harvests a year.
2. Variety classification of rice
According to China's national standards, rice grain is divided by its growth period, grain shape and grain quality into five categories: early indica rice grain, late indica rice grain, japonica rice grain, indica glutinous rice grain and japonica glutinous rice grain.
Indica rice grains are slender and long, shaped like a long oval or slender form, with low grain strength and poor pressure resistance. During processing they easily produce broken grains, and the milling yield is relatively low. The cooked rice expands more and is less sticky. Japonica rice grains are short and broad, relatively thick, shaped like an oval or egg shape, with high grain strength and good pressure resistance. During processing they do not easily produce broken grains, and the milling yield is relatively high. The cooked rice expands less and is more sticky.
According to differences in grain quality and harvest season, indica rice and japonica rice can also be divided into two categories: early rice grain and late rice grain. For the same type of rice grain, under normal circumstances, early rice grain has a larger white belly and fewer vitreous grains, and its quality is inferior to that of late rice grain. Early rice grain is loose in quality and poor in pressure resistance, easily produces broken grains during processing, and has a relatively low milling yield. Late rice grain, however, is firm in quality and good in pressure resistance, produces fewer broken grains during processing, and has a relatively high milling yield. As for the eating quality of the cooked rice, early rice grain is inferior to late rice grain. If comparing the quality of early and late rice grain, the quality of late indica rice grain is still superior to that of early indica rice grain.
Glutinous rice grains are milky white, opaque or semi-transparent, and very sticky. By grain shape they can be divided into indica glutinous rice grain (the grains are generally oval or slender) and japonica glutinous rice grain (the grains are generally oval).
