How to Grow Japonica Rice: Latest Technical Method Tutorial
Japonica rice is actually a variety of rice and a very common staple food, with a cultivation history of more than 6000 years. It is grown throughout our country, and the grains of japonica rice are relatively short and round, and in many places it is used to make porridge. At present, the planting area of japonica rice is very extensive, and there is still a trend of expansion. So how should japonica rice be grown? Below, the editor brings you the cultivation techniques for japonica rice. Let's take a look!
1. Land selection and seed soaking
Japonica rice has relatively strong growth ability, but it is still necessary to choose soil with sufficient fertility and strong drainage and irrigation capacity, the same as ordinary rice planting soil. Then carry out land preparation work on the soil, plow it deeply, and apply sufficient base fertilizer to improve soil fertility. Then choose seeds with strong germination ability, plumpness and fullness, and strong disease resistance to ensure planting benefits. And before planting, we also need to soak and disinfect the seeds. According to the main target of prevention and control, use the corresponding chemicals to eliminate pathogens inside the seeds, prevent infection by pests and diseases, and improve the survival rate of japonica rice.
2. Cultivation management
When planting, we should plan different management priorities according to the growth stages of japonica rice. In the early stage of planting, attention should be paid to promoting early seedling emergence of the seeds, strengthening management after emergence, and doing a good job in transplanting and field establishment. In the middle stage, the management focus should be on the stems of the japonica rice plants, promoting the growth of strong panicles and large panicles. In the later stage, the focus should be on roots and leaves, improving root growth ability, enhancing leaf photosynthesis, and increasing the accumulation of photosynthetic substances. Promote flowering and seed setting of japonica rice, strengthen the growth ability of japonica rice, increase yield, and expand planting benefits.
3. Fertilization management
Before planting, we should apply sufficient base fertilizer. The base fertilizer should mainly be decomposed farmyard manure, and the amount should be controlled according to the planting area. Then the amount of fertilizer should also be reasonably adjusted according to the growth period of japonica rice. For example, when fertilizing at the tillering stage, nitrogen fertilizer should be the main type, and after heading, grain fertilizer should be applied to meet the nutrients needed for rice growth. When fertilizing, attention should be paid to flexible adjustment according to the growth condition of japonica rice, weather, and so on. When the leaves of japonica rice are dull and lusterless, drooping and weak, and the weather is good, apply appropriately more; otherwise, apply less or not at all.
4. Water management
After field establishment, the root absorption capacity of rice is relatively poor, and when the temperature is high and the wind is strong, water evaporation will be accelerated. Therefore, after transplanting rice seedlings, we should keep the field water level at about 4 cm. After the rice enters the green-turning stage, indirect watering should be the main method. When the rice begins tillering, leave the field without standing water to control tillering growth and improve soil permeability. Promote thick and strong stems and improve the lodging resistance of rice. Water should also not be too much. When there is too much water, attention should be paid to drainage work to avoid root drowning, reduce rice respiration, and cause insufficient yield.
The above is a brief introduction to japonica rice cultivation techniques. The cultivation techniques of japonica rice are actually similar to those of rice. The main thing is also to pay attention to field management and enhance the growth ability of rice so as to expand planting benefits. That is all for today's introduction.
