Rice requires high yields and plant management is key. For rice to grow well, fertilization is indispensable. Fertilization is a stressful method. It cannot blindly apply fertilizers, scientifically arrange fertilization time and fertilization types, and promote the efficient absorption of rice, thus ensuring the nutritional needs of rice at all stages of its growth. Therefore, it is very important to master the fertilization technology of rice. Now the characteristics of fertilization and related fertilization techniques for rice in various periods are briefly described as follows: The rice growth period is divided into: seedling stage, tillering stage, jointing stage, booting stage, heading stage, anthesis stage, filling stage and maturity stage. During the growth of rice, 17 nutrients such as carbon, hydrogen, oxygen, silicon, nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, boron, copper, molybdenum, and chlorine are needed. The difference between supply and demand is different at different times. The major nutrient elements are nitrogen, phosphorus, and potassium. How to supplement fertilizers in each growing period? In general, every 500 kilograms of rice produced will require 8-16 kilograms of pure nitrogen from the soil, 4-7.5 kilograms of phosphorus (phosphorus pentoxide), and 9-19 kilograms of potassium (potassium oxide). Absorption of elements is distributed in every growing period of rice. The following are the absorption patterns of three nutrient elements of nitrogen, phosphorus and potassium in rice: The absorption of nitrogen by rice is transplanted into the booting stage, which accounts for about 10% of the total amount; The tiller - booting period, about 80% of the total; Booting - mature period, about 20% of the total. It can be seen from the above that the two peak periods of nitrogen requirement for rice are as follows: the tillering stage and the booting stage. In these two growth and development stages, we must pay attention to nitrogen supplementation! The absorption pattern of phosphorus for rice is divergent--the booting stage, accounting for about 50% of the total; Booting - mature period, about 50% of the total. From the above, it can be seen that the two peak periods of phosphorus requirement for rice are: tillering jointing and heading, and the appropriate amount of phosphorus supplementation is to ensure the balanced nutrition of rice. The absorption pattern of potassium for rice is turning green - it takes about 5% of the total amount during the tillering period; Childbirth - young panicle differentiation period, accounting for about 35% of the total; Spike differentiation - flowering period, accounting for about 60% of the total. From the above, it can be seen that the two peak periods of potassium requirement for rice are the period of differentiation and flowering of young panicles. After the heading date, the absorption of nitrogen, phosphorus, and potassium in rice gradually weakened. The nutrients needed during the grain filling period were mostly stored in the early stage of heading. Therefore, when fertilizing, we must master the normal fertilization time and control the amount of fertilizer. Complementing the nutrients needed for rice at various stages is the key to ensuring the growth of rice seedlings. The timely addition of nutrients will not only promote the early growth and growth of rice, but also increase the yield of rice. Our natural sweetener is extracting from natural plant.
