Rice harvesting technology
Rice harvesting is very important. The harvest will have a direct impact on the appearance, quality, taste and yield of rice. It also affects the number of striated grains and the rate of rice yield. Therefore, timely harvesting is very important and cannot be harvested too early. And can't be harvested too late. Harvesting affects maturity too early, reduces 1000-grain weight, and the quality is not high, resulting in more glutinous grains, more green rice, lower yield, lower rice yield, poor quality; too late harvest, easy loss of grain loss, frost damage, The stalks are folded down, the live stalks cannot be matured, the rice husks are thick, the rice is darkened, dull, and the rice quality is lowered. A suitable harvest period is generally carried out about 45 days after rice heading . It is necessary to make progress in accordance with the locality, the time and the situation, and harvest in time to achieve a bumper harvest. Â Specifically, the timely harvesting period of rice is determined by the fact that 97-98% of the rice ears turn yellow, and 2-3 grains of yellow in the base of the ear are light green, which is a timely harvest period. To sort out the harvesting order, first harvest the early-maturing varieties, harvest the mid-maturing varieties, and collect the late-maturing varieties. High-quality rice varieties can be harvested when 90% of the grain is yellow in each ear . In the harvest, we must improve the quality, adhere to the standards, and cut the middle and the right, which is conducive to the fall of the land. Â Artificial harvesting should be bundled with small bundles. The rice bales are coded in the field and turned once every 5-7 days to prevent cockroaches. It is better to use cross-shaped scorpion to prevent rain and snow from being wet, and to prevent freezing and cracks. In the harvest, it is necessary to cut and pick, and collect finely, and the particles are not lost. It is also necessary to cut the low cuts and cut the edges and fall to the ground, which is conducive to autumn and land preparation, preparing for rice production next year, and laying the foundation for the harvest of rice harvest next year to create conditions.
