"Grain" covers a wide range, including rice, wheat, millet, soybean, etc. and other grains, mainly plant seeds and fruits, which are the traditional staple food of many Asian people. Different grains have different methods of planting.Today, we mainly talk about rice planting skills.
1. Soaking seeds
Rice has a relatively strong growth ability, but it is still necessary to choose ten soils with sufficient fertility and strong irrigation and drainage capabilities, which can be the same as ordinary rice planting ten soils. Then carry out soil preparation work, plough it deeply, and apply sufficient base fertilizer to improve soil fertility. Then choose seeds with strong germination power, plumpness and strong disease resistance to ensure planting benefits, and we also need to soak and disinfect the seeds before planting, and use corresponding chemicals according to the main control objects to eliminate the germs in the seeds. , to prevent infection of diseases and insect pests, improve the survival rate of japonica rice.
2. Cultivation 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 early seedling of seeds, strengthening management after emergence, and doing a good job in transplanting and planting. In the mid-term, the management of the stalk of the japonica rice plant should be the focus to promote the growth of strong ears and large ears. In the later stage, the roots and leaves are mainly used to improve the growth ability of the roots, enhance the photosynthesis of the leaves, and increase the accumulation of photosynthetic substances. Promote the flowering and fruiting of japonica rice, strengthen the growth ability of japonica rice, increase yield, and expand planting benefits.
3. Fertilization management
Before planting, we should apply enough base fertilizer. The base fertilizer is mainly decomposed farmyard manure, and the amount should be controlled according to the planting area. Then, the amount of fertilizer should be adjusted reasonably according to the growth period of the japonica rice. For example, when fertilizing in the tillering stage, hydrogen fertilizer is mainly used, and then grain fertilizer is applied after heading to meet the nutrients required for rice growth. When fertilizing, pay attention to adjust flexibly according to the growth of the rice and the weather. When the leaves of the rice are dull and drooping, when the weather is better, apply more, otherwise, apply less or not.
4. Moisture 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 air volume is large. Therefore, we should keep the water level in the field at about 4 cm after transplanting. After the rice enters the greening period, we mainly use indirect watering. It can promote the sturdy stems and improve the lodging resistance of rice. The water should not be too much. When there is too much water, attention should be paid to drainage work to avoid root retting and reduce the respiration of rice, resulting in insufficient yield.
