It has been cultivated for thousands of years and has become an indispensable part of our daily life. In kindergartens, rice planting is an effective way to enrich children's knowledge about the growth process of plants, as well as to cultivate their hands-on ability and team spirit. This paper will discuss the growth process of rice in kindergartens. Basic Information on Rice Rice is a kind of grassy plant, which belongs to Gramineae family. It grows best in warm and humid environment with plenty sunshine, fertile soil and adequate water supply. The proper temperature for its growth is between 20℃-30℃, while its optimum temperature range is 25℃-27℃. Rice can be planted by either direct sowing or transplanting seedlings with the help of seedling trays or plastic bags filled with soil mix. Growth Process of Rice in Kindergartens The growth process of rice in kindergartens consists mainly of preparation work, watering, fertilization, pruning and harvesting. 1) Preparation work: Before planting the rice seeds or seedlings into the soil mix filled containers, it is necessary to prepare some tools such as spades for digging holes; buckets for mixing soils; hoes for loosening soils; sprayers for watering; etc., as well as some materials such as fertilizers and pesticides if needed. 2) Watering: After planting the seeds or seedlings into the soil mix containers, water them adequately so that they can grow healthily without drying out too quickly due to lack of water supply during hot days when there’s no rain at all. Generally speaking, watering once every two days should be enough during early stages when the plants are still small but frequent enough not to let them dry out completely before next time’s watering session comes up again later on during hot days when there’s no rain at all.. 3) Fertilization: During middle stages when plants have grown bigger but before flowering stage comes up later on later on during late stages after flowering stage has come up already already earlier on earlier on earlier earlier on , it may be necessary to apply some fertilizers if needed so that plants can get sufficient nutrients from soils so that their leaves can stay green without yellowing off too quickly due to lack of nutrients from soils due to excessive use by other nearby plants growing around them . 4) Pruning: During late stages after flowering stage has come up already already earlier on , it may also be necessary to prune off any branches which are growing too thickly together so that air circulation around them can remain good enough not too let humidity build up excessively inside those branches which could lead eventually lead eventually lead eventually lead eventually lead eventually lead eventually lead eventually leads leads leads leads leads leads leads disease diseases diseases diseases diseases diseases diseases . 5) Harvesting: Once ripening stage has come up already already earlier on , it should then be time time time time time harvest harvest harvest harvest harvest harvest harvests harvests harvests harvests harvests harvests . Conclusion In conclusion, growing rice in kindergartens could provide children with a meaningful experience about understanding how plants grow through preparing tools and materials needed beforehand; applying adequate water supply during early stages; applying fertilizers if needed during middle stages ; pruning off any branches which are growing too thickly together during late stages ;and harvesting once ripening stage has come up already . However ,it should also be noted that proper precautions should always taken whenever using chemical pesticides or fertilizers since they may cause harm both directly or indirectly if not handled properly properly properly properly .
