Early rice cold-proof technology

This year's spring sowing period appears to be "cold and cold". Therefore, during spring sowing, we must pay close attention to changes in the weather, make reasonable arrangements for the sowing period and the sowing period so as to ensure that we will cultivate the strong and strong when we do not mistakenly farm and lay the foundation for the early rice harvest. Introduce the cold rice seedling technology of early rice: 1. Reasonable species layout and timely planting. Get ready to prepare for the seed early. During the sowing period, the factors such as the growth period of the varieties, the collocations, the climate characteristics, the way of raising the rice seedlings, the late rice sowing and transplanting period (or Other postproduction) and other factors should be fully considered. At the same time, carefully compare the spring and spring conditions of the year-round and the previous year, and arrange the broadcast period. 2. We will promote new technologies for raising eel, such as dry nursery, dry seeding, and throwing seedlings. When using this technology, it should be noted that: First, choose fertile vegetable garden soil or dry land to be used as a dry nursery area; second, control the seeding rate, seedling age, and basic seedlings in the field; and third, do three throws when planting seedlings; The fourth is to spray paclobutrazol on a full scale, and to promote the use of special agents for breeding such as Zhuangzhi. 3. Dip sowing timely. According to the weather forecast, timely soaking and germination, after breaking the chest to seize the fine sowing. Doing "see the perennial period of sowing, look at the time of the sowing time," grabbed the "cold-tail warmer" weather, and soared the crop. 4. Thin tube seedlings. Do a good job of preparing for the "cold winter" defense. The first is to fully promote thin film seedlings; the second is to increase the use of plant ash, fire soil and other hot fertilizers; the third is a leaf-wrapped period of paclobutrazol, two leaves of the center of the spray spraying plant power 2003 and other leaf fertilizer, a leaf core In case of low temperature during the cold period of the two-leaf enveloping period, drought and eel throwing are liable to occur with blight, and it is necessary to emphasize spraying with pesticides such as enemy cough pine. Fourth, when the temperature is low, it should be sunny and avoid sudden film removal. Uncover the film, do not apply urea and other fast-acting fertilizers blindly. Do not suddenly cut off water to prevent physiological dehydration. 5. Check seedlings supplemented broadcast. After the cold damage, immediately check the seedlings into the field, especially in the two leaves before and after the package period, the impact of cold damage rotten species, should be promptly reseeding. 6. Prevention of pests and diseases in Putian. We must focus on the prevention and control of diseases such as cotton rot, blight, bacterial wilt, and seedling mites. Seed disinfection should be done before sowing, and medicine should be transplanted into the fields. 7. Grab and grab the pipe. Early in the field, the field waits until the earthworms, with fertilizer with medicine inserted into the field. Improve the quality of transplanting, achieve the appropriate age, shallow insertion, seedling reduction, deep application, strict specifications, timely application of herbicides after plugging. Pay attention to early warning of premature hair. We strive for low birth rates, increase the percentage of spikes, and build a high-yield shelf.
