The latest course on planting techniques and methods of Japonica Rice

Japonica rice is actually a variety of rice, is a very common staple food, it has been planted for more than 6000 years. It is cultivated all over our country, and the shape of japonica rice is relatively short and round, so it is used to make porridge in many places. Now the planting area of japonica rice is very extensive, and there is a trend of expansion. So how to grow japonica rice? The following editor brings you the planting technology of japonica rice, let's have a look!

1. Selecting land and soaking seeds

The growth ability of japonica rice is relatively strong, but it is still necessary to choose soil with sufficient fertility and strong drainage and irrigation capacity, which is the same as that of ordinary rice planting soil. Then carry on the soil preparation work, turn it deeply, apply sufficient base fertilizer to improve the soil fertility. Then select the seeds with strong germinating power, fullness and strong disease resistance to ensure the planting benefit. And we have to soak and disinfect the seeds before planting. According to the main control objects, the corresponding agents were used to eliminate the germs in the seeds, prevent the infection of diseases and insect pests, and improve the survival rate of japonica rice.

2. Cultivation and management

When planting, we should plan different management priorities according to the growth stage of japonica rice. In the early stage of planting, attention should be paid to promoting the early emergence of seeds, strengthening management after emergence, and doing a good job of transplanting and planting. In the middle stage, the stem of japonica rice plant should be the focus of management to promote the growth of strong panicle and large panicle. In the later stage, roots and leaves were mainly used to improve the growth ability of roots, enhance the photosynthesis of leaves and increase the accumulation of photosynthetic matter. Promote the flowering and fruiting of japonica rice, strengthen the growth ability of japonica rice, increase the yield and expand the planting benefit.

3. Fertilization management

We should apply sufficient base fertilizer before planting, the base fertilizer is mainly rotten farm manure, and the dosage should be controlled according to the planting area. Then the amount of fertilizer should be adjusted reasonably according to the growth period of japonica rice. For example, nitrogen fertilizer is the main fertilizer at tillering stage, and then grain fertilizer is applied after heading to meet the nutrition needed for rice growth. When applying fertilizer, we should pay attention to the flexible adjustment according to the growth of japonica rice, weather and so on. It is appropriate to apply more when the leaves of japonica rice are dull, weak and the weather is good, otherwise it can be applied less or not.

4. Water management

The root absorption capacity of rice after planting is relatively poor, and the evaporation of water will be accelerated when the temperature is high and the wind volume is high. Therefore, we have to keep the field water level at about 4 cm after transplanting. After the rice entered the green stage, indirect watering was the main method. When rice tillers are produced, the fields are shelved to control the growth of tillers and improve soil permeability. Promote the sturdiness of stems and improve the lodging resistance of rice. Water should not be too much, when there is too much water, we should pay attention to do a good job of drainage, avoid retting roots, reduce the respiration of rice, resulting in insufficient yield.

The above is a brief introduction of japonica rice planting technology. In fact, the planting technology of japonica rice is similar to that of rice, and it is mainly necessary to pay attention to field management and enhance the growth capacity of rice in order to expand planting benefits. That's all for today's introduction. This article is for reference only. I hope it can help you all.
