Application of Soil Nutrient Quick Measuring Instrument in Determination of Chestnut Fertilization

Nitrogen fertilization often causes excessive fertilization during the chestnut planting process. This can easily lead to excessive vegetative growth, leading to imbalances in vegetative growth and reproductive growth, reducing fertilizer use efficiency, and adversely affecting the ecological environment. After the soil nutrient tester measures the nutrient content in the soil, it is of great importance to improve the scientific fertilization level of the chestnut, to improve the cultivation benefit of the chestnut and to protect the ecological environment. In view of this, we conducted a study on the relationship between the production and legume branches of chestnut and soil nutrients, and provided a theoretical basis for scientific fertilization of chestnut.

According to the determination of soil nutrient fastness meter, the direct effect of available phosphorus on strain production is 0.8120. The principle is that phosphorus is a raw material of phospholipids, RNA and deoxyribonucleic acids, and it is also an important participant in photosynthetic phosphorylation and oxidative phosphorylation. The formation of chestnut female flowers, fruit color, sugar content, flavor, etc. have a significant impact. Its indirect effects of nitrogen hydrolysis by organic matter are negative, and the indirect effect of nitrogen through hydrolysis is 0.5129, indicating that nitrogen will affect the effect of phosphorus on a yield. The effect of available phosphorus on the production of chestnuts by available potassium is 0.5711, indicating that the use of potassium is beneficial to increase the effect of phosphorus on yield. After the positive and negative offset, the contribution of available phosphorus to the strain production is 0.8676. Therefore, it is very beneficial to select the mountain cultivation chestnut with high content of available phosphorus for the growth of the results.

The direct effect of hydrolyzable nitrogen on strain production was 0.6266, but its indirect effects on strains through available phosphorus and available potassium were as high as 0.6647 and 0.6293, respectively, and the correlation coefficient was as high as 0.6646, indicating that nitrogen is also the main factor that constitutes the output of chestnut. The principle is that nitrogen is the main component of amino acids, proteins, and nucleic acids and plays an important role in flower bud differentiation. However, the pathway mainly uses phosphorus and potassium to affect the yield. Therefore, nitrogen fertilizer application efficiency is measured by a soil nutrient measurement instrument. The increase depends on the corresponding increase in the level of phosphorus and potassium in the soil. This requires us to comprehensively consider the appropriate proportion and amount of nitrogen, phosphorus and potassium nutrients in chestnut fertilization in order to maximize the economic benefits of fertilization.
