Effect of humic acid compound fertilizers on Potato Growth Status/Yield and Quality

July 15, 2022

In order to clarify the types of humic acid compound fertilizers suitable for potato production, random block experiments were conducted through 8 kinds of humic acid-type compound fertilizers and conventional compound fertilizers to study the effects of different types of humic acid-type compound fertilizers on potato growth and yield. impact on quality. The results showed that, compared with the common compound fertilizer treatment, the humic acid compound fertilizer could promote the growth of the aerial parts of potatoes during the starch accumulation period. Among them, the Ⅵ humic acid compound fertilizer treatment had the highest potato plant height of 109 cm, and the type II humic acid compound fertilizer had the highest plant height. The aboveground treatment increased by 58.29; the yield increase rate of some humic acid compound fertilizer treatments reached 11.24 to 11.96, among which, the Ⅷ humic acid compound fertilizer treatment had the highest yield, which was 26000kg·hm-2, and the yield increased by 11.96; the humic acid compound fertilizer treatment could effectively promote the nutrition of potato. Accumulation and improvement of some potato quality indicators; almost all of the 8 kinds of humic acid compound fertilizers can promote the partial productivity of potato nitrogen, phosphorus and potassium fertilizers, and the increases are 11.24-11.96, 8.85-11.96, 8.85 respectively.

As one of the important components of organic matter, humic acid has good physiological activity and functions such as absorption, complexation and exchange. Enhance the anti-stress performance has a good role in promoting [1-8]. The long-term application of chemical fertilizers in some areas has caused problems such as soil degradation, decreased soil microbial activity, decreased organic matter content, low fertilizer utilization efficiency, and decreased crop quality [10-11]. soil physical and chemical properties, soil fertility status, promote the growth and development of potatoes, improve the quality of potato tubers.

By analyzing the following questions:

1. Effects of different fertilization treatments on the growth of potato plants

2. Effects of different fertilization treatments on potato yield

3. Effects of different fertilization treatments on nutrient absorption of potato tubers

4. Effects of different fertilization treatments on the nutritional quality of potato tubers

5 Fertilizer partial productivity of different fertilization treatments

Conclusions: humic acid compound fertilizer (Amino Humic Shiny Ball) treatment can significantly increase potato yield, can better promote the accumulation of phosphorus and potassium elements in potato expansion stage, phosphorus element in mature stage, and promote the absorption of nutrient elements, which is consistent with Sui Changling et al. The results of the research on the acid fertilizer on dragon fruit were roughly the same; some humic acid compound fertilizer treatments significantly increased the crude protein and reducing sugar content of potato, the crude protein content increased by 10.53, and the reducing sugar increased by 37.50 ~ 43.75, which is consistent with Zhou Chao et al. 14] The research results on the application of humic acid fertilizer to watermelon in greenhouses are roughly the same. Therefore, humic acid compound fertilizer treatment can effectively promote potato nutrient accumulation and improve some potato quality indicators.

Compared with the common compound fertilizer treatment, the humic acid compound fertilizer can almost all promote the partial productivity of potato nitrogen, phosphorus and potassium fertilizers, and the increases are 11.24-11.96, 8.85-11.96, 8.85-11.97 respectively.
