The latest course of Rice planting techniques and methods

Rice is an indispensable staple food for southerners every day, and it has a very extensive planting area in the south of our country. Almost every household in rural areas has planted it, and with the continuous growth of population in our country, the demand for rice is also increasing. There are still many new growers to join, but their planting techniques are not very mature. The following editor brings you the rice planting technology, let's have a look!

1. Seed treatment

Excellent rice seeds should be selected before planting, and purebred full seeds that can adapt well should be selected according to local weather changes and soil conditions. Then soak the seeds for disinfection and pay attention not to hurt the seeds during disinfection. Disinfectants such as strong chloroform can be used to disinfect the seeds effectively without causing harm to the seeds. Soak the seeds and then wrap them with wet net yarn to accelerate germination, control the temperature at about 31 degrees, pay attention to turning the heap when the temperature increases, and lower the temperature to about 25 degrees when most of the seeds are white. During budding, we should pay attention to the change of temperature, control the temperature within a suitable range, and sow and raise seedlings in time after being cool and dry.

2. Seedling raising and transplanting

The common method of raising rice seedlings in rural areas of our country is to raise rice seedlings on the seedling tray, prepare the nutritious soil in the seedling plate, apply sufficient base fertilizer, the base fertilizer is mainly farm manure, combined with appropriate amount of compound fertilizer, mix it with the soil evenly. Sow seeds timely when the temperature is above 7 degrees, cover fine soil after sowing, increase soil temperature, and ensure that seeds can germinate normally and all kinds of nutrients needed for germination. After emergence, it is necessary to do a good job in seedling management, high-quality rice seedlings is the key to ensure the successful cultivation of rice, when the seedlings grow to about 8 cm, they can begin to transplant seedlings.

3. Water and fertilizer management

Rice has a great demand for water, and it is necessary to ensure a certain water level in the rice field during the whole growth period of rice. And according to the growth of rice and soil water content appropriate watering, such as in the young heading stage and heading flowering stage is a large amount of water demand, these two periods to ensure that there is sufficient water, timely watering. The fertilization of rice is also very important. The tillering stage is the first period when rice needs a large amount of fertilizer, so the first topdressing should be carried out. Adequate nutrition can promote the growth of rice seedlings, ensure the plumpness of rice panicle, increase the yield, and then fertilize properly according to the soil and rice growth in the middle and later stage.

4. Field management

Generally, there is the phenomenon of empty planting after transplanting, so we also need to do a good job of checking seedlings after transplanting. If there are holes, we should make up high-quality rice seedlings in time to ensure the planting density and the number of basic rice seedlings. And the field sealing agent can be sprayed properly before and after transplanting to inhibit the germination of weed seeds in the rice field. Weeding should also be done after transplanting to prevent weeds from grabbing the growth and nutrition of rice seedlings. Weeding should also be done at the same time to do a good job in pest control, rice pests are relatively serious, common leaf miners, can be properly sprayed insecticides for control, pay attention to the dosage to prevent harm to rice.

The above is a brief introduction of rice planting technology, in fact, China's rice planting technology has been very mature. However, there will still be some planting failures, mainly due to improper management, so I hope everyone should do a good job in field management when planting to ensure the normal growth of rice and avoid some unnecessary losses. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
