The analysis of soil nutrient content by soil fertiliser detector combined with the small amount of accumulated dry matter in the cotton seedling stage results in less absolute demand for nutrients. The absorption of nitrogen in the seedling stage accounts for only about 5% of the total amount absorbed during the whole growth period. However, the response of cotton to fertilizer is sensitive. The level of soil fertility, how much fertilization at the seedling stage has a great impact on the growth and development of cotton seedlings. Appropriate fertilization, especially the application of available nitrogen and phosphate fertilizers, has a good effect on the promotion of root development and seedling growth, can increase the resistance of cotton seedlings to adverse environments, and promote the growth of true leaves and early bud emergence. Nitrogen deficiency at the seedling stage inhibited vegetative growth and delayed bud emergence.
Phosphorus is a component of important compounds in cotton, which can enhance the synthesis and operation of carbohydrates, and can promote the metabolism of nitrogen, promote the synthesis of fat, and improve the resistance and adaptability of cotton to the external environment. Phosphorus is an important component of nucleic acids, phospholipids, protoplasm and nuclear proteins. Phosphorus plays an important role in the metabolism of cotton carbohydrates. Increasing the phosphorus content can increase the absorption of nitrogen by cotton plants, and the nitrogen in cotton plants also increases significantly. The lack of phosphorus in cotton plants seriously affects the number of bolls, yield, and quality. Therefore, superphosphate and monoammonium phosphate are also the fertilizer formulations and important fertilizer components of this bed soil conditioner.
Cotton is a high-potassium crop and cotton seedlings require a large amount of potassium. There are dozens of enzymes in cotton that require potassium ions as activators. Therefore, potassium can promote a variety of metabolic reactions and is beneficial to the growth and development of cotton. Potassium can promote the photosynthesis of cotton, promote glucose metabolism, promote protein synthesis, and have a good effect on nitrogen metabolism. Potassium can promote the economical use of cotton, cotton absorbs more potassium, the root system is developed, and the ability to resist drought is enhanced. Moreover, potassium can enhance the resistance of cotton, disease resistance, promote the normal development of cotton tissue and mechanical organization, so that the cotton stem is tough and not easy lodging, cotton seedlings are strong.
Based on the above data analysis of available nitrogen, available phosphorus, available potassium, and active acid (pH), since the mixed fertilizers used in the treatment 1 and treatment 2 soil samples are more, the indicators in the soil are better than the treatments 3 and 4 The soil samples were high in soil and the soil fertility in cotton seedbeds was significantly improved. The application of fungicides and growth regulators had no significant effect on the content of various components in the soil.
Through the determination of soil fertiliser detectors, bed soil conditioner 1 and bed soil conditioner 2 can promote the growth and development of cotton seedlings, which is conducive to healthy growth and development of cotton seedlings. In addition, the content of potassium in each soil sample, especially the content of available potassium, is relatively low, and the acidity of the soil is also high, which has an adverse effect on the growth of cotton. It is necessary to increase the amount of potash fertilizer and add an appropriate amount of acid in bed soil conditioners. Alkali regulators provide the best results for soil physicochemical properties.
The history of planting cotton in China is very long. During the cotton growing period in the south of China's cotton region, it is during the Spring Festival with low temperatures, rain, and sunshine. This has led to problems such as low germination rate and reduced seedlings rate. This has seriously affected the yield and quality of cotton. The physical and chemical properties of soil in cotton seedlings have a certain influence on the growth and development of cotton seedlings. For the soil characteristics of cotton seedlings, reasonable fertilization is an important measure to improve the seedbed and develop cotton production. According to soil type, nutrient abundance and nutrient condition of cotton seedlings and fertilizer effect function, optimizing the application of nitrogen, phosphorus, potassium and trace element fertilizers is the basic guarantee for improving the quality of cotton seedlings. This test measures the available nitrogen, available phosphorus, available potassium, and active acid (pH) in the soil after application of different bed soil conditioners to the cotton seedbed in order to determine the abundance of its nutrient elements and to prepare the bed soil conditioner. Formulations provide an important reference. For the determination of soil nutrients in cotton fields, soil fertiliser detectors can be used for detection and analysis to provide basis for fertilization.
