Seedling raising time of wheat stubble
The seedling raising time of indica rice is from the end of April to the middle of May, from north to south, from along the Huai to Jianghuai between the successive stops, the machine transplanting time of wheat stubble indica rice is about half a month before the wheat harvest, because the seedling raising time of wheat stubble rice machine transplanting is 18~22 days, early seedling, around mid-May.
Japonica rice is more intolerant to low temperature, and the winter fallow field can not raise seedlings too early, too early to encounter low temperature to form a yield decline, the seedling raising time of japonica rice is May 10th ~ 20th, from north to south successively expanded. The seedling raising time of wheat stubble japonica rice is half a month before the wheat harvest.
Seed soaking
Nowadays, there are more and more large-scale planting, and now the obvious diseases such as seedling blast and bad seedling disease in the rice seedling stage cannot be treated with pesticides at that time, so it is recommended that large planters must be soaked in pesticides and then mixed with pesticides. You can choose prochloraz and cyanostrobin 2000~2500 times for soaking seeds for 10~15 hours, and then stop raising seedlings with water and then stop germination.
It is recommended to promote the germination of seedlings in water twice, try not to promote germination once, spread out the seeds to dry when the germination is broken at the time of the chest, and then stop the seed dressing, such as Obairy, Shileshi, Gaoqiao, Eagle Primary Medicine, if there are more birds and finches in other places, you can also add a little bird repellent, such as a good winter and so on. After seed dressing, the second germination is stopped, because the first germination is not conducive to the emergence of all buds, and the effect of the seed coating agent is reduced. After the second germination is about 24 hours after soaking, take it out and spread it out to dry, and then you can harvest it in the field.
Precautions for sowing
The seedling field must be leveled to avoid rotten seedlings; It is recommended that you cover a layer of sterile grass after harvesting, and then cover it with film, do not indirectly cover the film on the rice seeds, in case some of the temperature is too high to roast the newly germinated rice seedlings.
Focus on seedling leaf blast, blight, cotton rot, rice in the 3-leaf stage must pay attention to the prevention and control of seedling leaf blast, you can choose Han Daoai, Ami Miao harvest, Na Enemy stability and other agents. Shallow water and wet management of rice is conducive to the prevention of rice cotton rot, once the cotton rot occurs, you can choose dixone, quintonitrobenzene and other spray control, you can add some high-quality foliar fertilizer by the way, and drain the water in the morning.
Grass damage should also be noted, rice seedlings are relatively weak, the safety requirements of the agent are relatively high, and in previous years, there was more rain, so it can be presented at the same time, it is recommended that you choose a regular agent from a big brand and a large manufacturer.
