Embodiment 1

[0013] Dissolve and then dilute 5 times with wood vinegar and chitosan in the ratio of 3:100 (w / w), pour in the planting holes of cucumbers, pour 200ml in each hole, then transplant, routine management, follow-up investigation of the growth of cucumbers, Changes in yield and quality. Table 1 shows that the growth of cucumbers watered with chitosan solution is significantly better than that of the control, and the yield and quality have been significantly improved.

Abstract

The invention discloses a natural compound-based soil conditioner, which belongs to the technical field of chemical pesticides. The natural compound-based soil conditioner comprises the following components in percentage by mass: 97 to 99 percent of wood vinegar or bamboo vinegar and 1 to 3 percent of chitosan. The invention is a chitonsan saline and alkaline soil conditioning liquid which can reduce the pH value of saline and alkaline soil, increase crop yield and improve the quality.

Description

technical field [0001] The invention relates to a product in the technical field of chemical pesticides, in particular to a soil conditioner based on natural compounds. Background technique [0002] Chitosan (CTS), molecular formula (C6H11NO4)n, is a high molecular weight cationic polysaccharide, and it is an amino polysaccharide obtained by removing part of the acetylide group from chitin. Chitin, also known as chitin and chitin, is widely found in the shells of various arthropods such as shrimp, crabs and insects. It is also an important component of lower animals such as fungi and algae, and is also a common component of fungal cell walls. Components, related to the initiation and maintenance of fungal cells and the formation of compartments, are of particular importance for the growth and realization of fungal functions. The annual production of chitin in nature is about 10 billion tons. Among all natural polymers, the reserves occupy the second place, second only to ce...
