“…It obtained the official pesticide registration certificate in 2011 and became an advanced and applicable technology promoted by the Ministry of Agriculture in 2014 [27]. This technology is mainly used for soil disinfection treatment in indoor greenhouses, and the working conditions require airtight, high temperature, and water, which can effectively reduce the occurrence of soil diseases and pests [23,28]. A large number of studies have shown that Calcium Cyanamide can neutralize acidic substances in soil, and with the increase in the amount of Calcium Cyanamide, the pH value increases more significantly [29,30].…”

“…It can inhibit the occurrence of root-knot nematodes [18][19][20]. The temperature in the shed can reach more than 70℃, and the temperature at 15 cm of the ground under the film can still get more than 40℃ [21][22][23], and it is rarely applied on the open field. Studies have shown that the pesticide action of calcium cyanamide is mainly through its decomposition process to produce cyanamide substances, which can effectively inhibit and kill underground pests such as root-knot nematodes, pathogens, and weeds [24][25][26].…”

The cultivation of chili peppers in Zhanjiang City, Guangdong Province, China, has long suffered from root-knot nematode, which has caused significant economic losses. Commonly used chemical nematicides are highly toxic to humans and animals, and they can remain in the soil, damaging soil health and affecting the cultivation of subsequent crops. There is a need to find a green and safe alternative. Therefore, the present field experiment was conducted based on laboratory studies to evaluate the effect of treatment of open field with lime nitrogen followed by different fertilizers on the control of root-knot nematode in chili and its growth. The highest preventive effect against root-knot nematode was found to be 53.37% after applying lime nitrogen treatment in the open field, and the highest preventive effect was 80.42% when combined with fertilizers. Compared with the control, the maximum increase in soil temperature was 8℃, and the pH value of the soil was increased from 5.83 to 7.52, effectively improving soil acidification and structure and increasing soil fertility. The present results show that this technology can meet the expectations when applied on the open floor, but it needs to be combined with other measures. It can be carried out in combination with the summer fallow period.
