Four steps in rice planting
Rice cultivation is an agricultural technique with a long history that provides food for billions of people around the world. From the selection of seeds to the ripe harvesting, it is the crystallization of technology and experience. Through a detailed analysis of the four key links in the rice planting process, let us explore the mystery of this green field.
First of all, the journey of growing rice begins with "selection and processing". As the first step in the beginning of life, seeds are especially important for the cultivation of rice. Farmers should choose suitable rice varieties according to local weather conditions, such as heat-tolerant, disease-resistant and high-yielding varieties in the tropics, and cold-tolerant and early-maturing varieties in temperate or northern regions. Different soil conditions also have a certain relationship with the selection of different crops, for example, sandy loam soil is suitable for varieties with large fertilizer demand and long growth cycle, while under soil conditions, paddy fields with strong waterlogging tolerance root system should be preferentially cultivated. In addition, the trend of demand for high-quality rice, specialty rice and high-quality rice will also have a certain impact on rice production strategies.
Before sowing, the seeds are subjected to a series of pretreatments to make them viable. Drying seeds is an important job, which can not only reduce the water content, but also increase the vitality of the seeds, and at the same time kill some bacteria that adhere to them. The next step is soaking, and the right amount of water can make the seeds take root and germinate better. In addition, sterilization treatment, such as lime water, chemicals, etc., should be carried out to sterilize germs and germs to ensure the healthy growth of seedlings.
The second step is "ploughing and preparation", which is to provide the right conditions for rice to grow. After winter, farmers will use mouldboard ploughing to relieve the hardness of the soil, improve the aeration of the land, thereby promoting the microbial activity and degradation of organic matter in the soil, and providing sufficient nutrients for the growth and utilization of rice. Then the land is leveled to ensure the balance of water distribution, which provides convenience for future machine seedling planting and manual seedling transplanting. During this period, farmhouse fertilizer and compound fertilizer are the main ones to ensure the continuous nutrition during the whole growth period.
In the third stage of "sowing", seedling transplantation has been adopted in most places. The treated seeds are sown into a special seedling bed, carefully cared for, so that the seedlings grow to about 20-30 cm, at this time the seedlings have a strong root system, which is conducive to rapid adaptation and rooting to the new environment after transplanting. In some areas, due to geographical and climatic reasons, the "direct seeding" model is adopted, that is, the seeds are sown in the field to make them take root in situ, but this model puts forward higher requirements for cultivation technology.
The third is the key to "transplanting and management". The cultivated rice seedlings are planted into the rice field according to a certain specification, so that each seedling receives sufficient light, water and nutrients. After transplanting, fine field management was carried out, that is, timely and moderate watering should be carried out to ensure that the rice is "not dry and not dry"; In order to meet the needs of nutrients at each growth stage, fertilizers should be applied appropriately; Weeds should be removed frequently to prevent them from competing for nutrients and space; In order to ensure the normal growth of rice, the prevention and control of pests and diseases should be carried out in a timely manner. In autumn, the rice heading is flowering and filling, the rice is ripe, and the rice ears are drooping, which is a good time for harvest.
The above four links constitute a basic process of rice production, but in the actual operation process, it is also necessary to adjust according to the actual situation, according to the actual situation, according to the actual situation, and apply modern agricultural science and technology methods, only in this way can the yield of rice be stable, ensure food safety, and let the gift of this land continue to be maintained.
