According to the weather forecast, the weather during the planting of early rice in Ningxiang County this year was dominated by rainy weather. In order to ensure good seed soaking and breeding for early rice, the following technical opinions were specifically proposed:
1. Choose cold-resistant, high-yield and high-quality varieties, with Lingliangyou 268, Zhuliangyou 02, Luliangyou 996, Zhongza 39, Zhongjiazao 17 and Xiangzaoxian 45 as the main species.
2. Use mulch to cover floppy disk and raise seedlings. If conditions are met, take greenhouse planting and planting seedlings to prevent broadcast of dumb valleys and live broadcasts to prevent rotten rot due to low temperature.
3, grasp the sowing time. According to the meteorological conditions, the county warmed its head and sow cold heads on March 25 this year.
4. Appropriately increase the amount of seeds and the number of plates. According to the weather conditions this year, it is appropriate to use 10-12 pounds of conventional rice, 5-6 pounds of hybrid rice, and 90-100 holes of 308 holes of sorghum.
5. Strictly sterilize the seed and use germination to sow the habit of non-precipitating sowing. Before sowing, it is necessary to carry out strict drying, seed washing and seed disinfection in order to enhance seedling seedling resistance and prevent bastard disease. In particular, mid-to-late season 39 requires disinfection with prochloraz, so as to prevent bacon disease.

It has a significant role in improving the quality of seedlings, promoting the delivery, strengthening the resistance of seedlings, and preventing the damage caused by blight. The use of strong agents should be the choice of regular brands, do not want to be cheap, use some of the disinfectant content can not meet the normal standards of poor quality products. The use of the process should be strictly in accordance with the instructions for use, throwing clay per acre with a bag of strong agent and can fill the disk hole 2 / 3 of fine soil or thin mud mix well and then into the tray hole, thin mud tightly sowed. Be careful not to use the soil mixed with strong agent as cover soil.
7. Strengthen management in Putian. Seedling stage, high temperature and high humidity promote Qi Miao, 1 leaf 1 heart temperature suitable for moisturizing strong seedlings, prevent appetite, pay attention to prevent the occurrence of cotton rot, blight; 2 leaves 1 heart venturing seedlings, increase fertilizer promotion, cultivation Strong and strong; 3 leaves and 1 heart period to implement the day to open the night cover, can be suitable to apply manure water or urea to prevent defertilization, and should pay attention to choose the good weather timely cast seeding, remove all the film before transplanting 3-5 days, Increase its stress resistance.
