Lin Shifu, who lives in Shanghe Village, said that he recently went to the field to see the growth of rice, and found that many rice grains appeared empty. This can be anxious to Master Lin, how to do rice shells? Hui Nongwang Xiaolin to share the prevention and control measures of rice shells, I hope to help everyone!
Master Lin said: "The rice in the fields is mostly awkward, not mature, and the rice in Shibuya is still very much. There is not much grain in the rice."
When I saw that my rice fields were not green, Lin’s heart was not a taste. In previous years, at this time, rice should be ripening. What is this rice in this year?
In fact, the rice of Master Lin’s family is an empty valley phenomenon. The empty grain valley refers to the rice or millet with insufficient grain. Under normal climate and cultivation conditions, the average grain rate of rice is 10%-20%. . However, if the control is not good, the shell rate will be as high as 40%, which will greatly reduce the yield of rice in the current year and affect the rice harvest.
Because the local high temperature heat damage phenomenon is more serious than in previous years, the high temperature weather in the rice heading and flowering period has seriously affected the rice pollination, which led to the empty shell of rice.
Control measures for rice empty glutinous rice:
First of all, in the flowering stage from the booting to the heading and flowering stage, if there is high temperature or low temperature, the defensive measures should be taken in time to reduce the damage and increase the seed setting rate. When high temperature or low temperature occurs, spraying phosphorus and potassium fertilizer, and spraying 3% superphosphate solution or 0.2% potassium dihydrogen phosphate solution on the root can enhance the ability of rice to resist high and low temperature, thereby improving the seed setting rate of rice.
Secondly, pay attention to the prevention and control of rice pests and diseases, such as rice leaf roller, rice planthopper, rice sheath blight, etc., must remove the rice fields and surrounding pests and diseases, try not to let the pest source into the rice fields, early detection and early prevention and treatment, medication It should be determined according to the weather conditions. It is best to choose sunny weather. When the plants are dry, the application effect is best.
Finally, the field should be kept moist, and the fertilization should be kept up. For the late rice, the urea and potassium fertilizer-based ear grain fertilizer should be applied in a timely manner to enhance the high temperature resistance, promote growth, and meet the harvest!
What needs to be noticed is that in the field investigation, for the harvested fields with a seed setting rate lower than 10%, the empty rice ears should be cut off immediately, and the field water management and pest control should be strengthened to promote the regeneration and germination. Get a certain harvest.
I think this will be the beginning of the action, and Xiaolin also wishes his family's rice to be harvested! I hope that everyone will grow healthy rice and achieve high yield of rice!
