Wheat indica rice cultivation management considerations

Wheat indica rice breeding time

Japonica rice breeding time is from the end of April to the middle of May, from north to south, from the Huaihe to the Jianghuai one after another between the stop, wheat indica rice transplant machine master time before the wheat harvest about half a month, due to the rice seedling transplanting time Also 18 to 22 days, early childbirth, around mid-May.

Indica rice is more resistant to low temperature, winter can not be used to educate too early in the field, and it is easy to encounter low temperature to form a production drop earlier. Indica rice breeding time is May 10 to 20, from north to south. The cultivation of wheat indica rice time before the wheat harvest.

Seed soaking

Today, more and more large-scale planting, seedling rice seedlings, bastard disease and other manifestations of rice seedlings at the time can not be treated with pharmaceuticals, so suggest that large planters must be re-seeded in the premise of pesticide seed dressing. Proteolytic soaking can be selected from 2000 to 2500 times of prochloraz, cyanocastrobin, soaking for 10 to 15 hours, and then stopping the water breeding, and then stop germination.

Aquatic seedlings are recommended to germinate twice, so as not to germinate as much as possible. Once germinate until the chest breaks, the seeds are spread out to dry, and then the seed dressing is stopped. For instance, Albany, Shilokaku, Gao Qiao, Yingchu et al. If there are more birds in the field, you can add a bit of bird repellent, such as winter and so on. Seed germination and then stop the secondary germination, because a germination is not conducive to the Qi teeth, and reduce the role of seed coating agent. The second time the germination is about 24 hours after soaking it out and spreading it out to dry it.

Sowing precautions

It is important to level the paddy field to avoid rot. When it is sunny, it is easy to show the condition of low-temperature roasted seedlings. It is recommended that you cover up a layer of sterile grass after harvesting, and then cover it with a film. Do not indirectly indirect the film. Cover rice seeds to prevent excessive heat and damage to freshly sprouted rice seedlings.

Focus on seedling leafhopper, blight, cotton rot, rice must pay attention to the prevention and treatment of seedling leafhopper in the three leaf stage, you can choose Handao love, Ami Miao income, get the enemy stable and other agents. Shallow water and wet rice management is beneficial to prevent cotton rot. Once cotton rot is attacked, it can be controlled by sprays such as enemy pine and pentachloronitrobenzene. It can be used along with some high-quality foliar fertilizers to remove water in the morning.

Weeds should also pay attention to the fact that rice seedlings are relatively weak and have higher requirements for the safety of pharmaceuticals. In addition, the rains in previous years are more likely to be present at the same time. It is recommended that you choose the right-hand chemical for big brands and large manufacturers.
