When will the rice be harvested? What kind of tools are better for harvesting rice?

Moderate harvesting is beneficial to improving rice quality and reducing production losses. If harvested too early, the grouting will be incomplete, and the production volume will be reduced by more than 20%. Moreover, the millet grains are not round, with high chalkiness, and the rice quality is poor; if harvested too late, the rice will be overripe, which will easily cause grain damage, and the thresher will not work properly. The rice is easy to break, there are many broken rice, and the quality is reduced. Rice is generally harvested when 90%-95% of the grains are yellow and ripe, that is, 95% of the rice indicates that the rice variety has color, and only a few light green grains at the bottom of the ear are not completely chlorotic. The rice harvesting stage should also be determined based on local natural conditions.

Grouting begins 3-5 days after the rice is in full bloom. After grouting, the internal structure of the grain is milky white. With the continuous accumulation of cassava starch, the dry matter weight continues to increase. In the early stage of milk ripening, the biomass increases rapidly. In the middle and late stages, physical labor increases rapidly. In the later stage, the biomass is larger and smaller. The rice grains gradually harden and turn white, and the back turns green. This continues for 7-10 days. The content of the grains is thick and sticky, without milky matter. The grains in the middle of the ears have a hard feeling when pinched by hand. The biomass is reduced, and physical labor is required to achieve maximum results. The green color on the back of the millet grains gradually disappears, and the rice husk turns slightly yellow, which lasts for 7-9 days.

Generally, before harvesting, farmers will randomly pull out a few rice grains from the ears and bite the rice grains with their teeth. First, you can feel the strength of the rice when you bite it. Second, you can see how the rice is inside after biting off the rice. The rice is relatively hard, and it can be judged that it has basically been harvested according to the standard if it is not powdery or pulpy when chewed. In addition, the rice husks are basically yellow, and now it is time to harvest the rice. When harvesting rice, you should also pay close attention to weather changes.

Observe the color of the rice plants. When the color of most of the rice plants in the field changes from green to yellow, it is the first distinguishing point. Observe the color of the ears, they all change from green to yellow, starting from the middle, and slowly the entire ears will turn yellow. Observe rice grains. First, look at their color. The grains are yellow. Second, feel their strength. Hard ones are perfect. Third, look at their uniformity. Rice harvesting does not need to be too early or too late. If it is too early, the rice grains will not be round yet, and the moisture content will be too high, resulting in too much green rice, resulting in poor quality, low production volume, and low selling prices.
