Cultivation is at the forefront of rice. Cultivation is the basis for rice production in rice breeding. Depending on the water status of the rice fields, they are divided into water-bearing fields and dry fields. Depending on the water fraction of the field, it can be divided into water fields with water and dry fields with drought. According to the method used to clean the field, it can be divided into aqueous fields, such as aqueous fields, which may vary according to the temperature protection facilities in the field, but may also be divided into thin membranes to protect the warm breeding, greenhouses, etc., and small and medium seedlings, according to the method used to remove the field and the age of the seedlings。
In breeding, there are different characteristics depending on the method of breeding. There are also differences in the standard requirements for growth in breeding, and a number of common metrics still exist, depending on the criteria for breeding: in their breeding, there are broad foliage, growth and proper age; in their common measure, there are also strong photolytic and resistant。
The combination of seed processing, seeding and field management is included in rice breeding, each of which focuses on the extent of its treatment and is important for the cultivation and growth of the crop。
(1) before seed sprouts, the seed is first treated to poison its surface and to eliminate the fungus on the seed. The treatment of seeds includes the drying of seeds, selection, disinfection and inflammation。
(2) driving seeds can contribute to some extent to their growth and is important for their development and rational growth. Drumbs are effective in preventing seed decay and promoting seed growth. The seeding methods vary from greenhouse to hotbed to paddy drums. In the process of seeding, seeding is carried out in accordance with the characteristics and requirements of the seed, in the form of high-temperature, broken chests, drying and so forth。
(3) in the cultivation of rice, there is a correlation between sowing during the sowing period and the three who are of age. Good timing of seeding and effective breeding are important for the high productivity of seedlings and their harvest. During seeding, the main consideration is that the minimum temperature of seedlings is 12° c and 10° c, so that they are seeded in accordance with their temperature during the pre-sowning period and are followed by appropriate measures。
In the field, proper fertilization and irrigation are required. It is important to prevent the generation of rot and to promote seedling growth. The breeding process for seedlings is based on a rational method of fertilization of seedlings through fertilisation from their infancy, nursery, leaf and growth periods, thus contributing to their growth。
2. Reasonable planting
Rational planting of seedlings can lead to a high yield of seedlings by increasing their ears, particles and weight. Rational tightness can promote photocosynthesis and increase photoenergy utilization. Skin varieties, pre-literate varieties and poorly managed fields rely mainly on high-yielding cultivation for their growth purposes。
3. Management of rice fields
The management of paddy fields is divided into field management during the return period, field management during the long-duration period and field management during the long-duration period. During the anti-chromosomal period, mainly focused on nutritional organs, care is taken to fill the gaps and ensure full seedling; and comprehensive treatment of the disease is provided. During the elongation period, it is an important period for ensuring the growth of the elegance, paying attention to the fertilization and promotion of the elegance; rational irrigation; and integrated pest management. Nutritional growth is largely at a standstill during the spiking season, with attention to the breeding of roots, the preservation of ears and the increase in weight。
