Water-soluble humic acid fertilizer and preparation method

Abstract

The invention discloses water-soluble humic acid fertilizer and a preparation method. The water-soluble humic acid fertilizer is composed of 20-30% of bio-active humic acid, 10-15% of magnesium nitrate, 7-11% of citric acid, 8-12.5% of sodium tetraborate, 8-13% of urea, 2-8% of water-soluble monoammonium phosphate, 4-9% of potassium sulphate, 2-7% of zinc sulphate monohydrate, 1-6% of ferrous sulfate, 1-6% of thiamethoxam and 10.5-15% of hymexazol. The water-soluble humic acid fertilizer integrates the humic acid, major, medium and trace elements and pesticide, therefore, the utilization rate of lemons to the trace elements is improved, the etiolation phenomenon due to the fact that the lemons are lack of the necessary medium and trace elements is effectively improved, and meanwhile the etiolation phenomenon caused by pest and disease damage such as planococcodes robustus, thrips, root rot and damping off can be effectively controlled. According to the water-soluble humic acid fertilizer, the fast-acting property and the durability are integrated, the fertilizer application amount and the application times are decreased, soil hardening is reduced, the control effect is improved, the labor cost is lowered, the toxic effects of the pesticide on natural enemies and pollution of the pesticide to water are reduced, and the economical and biological benefits are significant.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation and utilization, and in particular relates to a water-soluble humic acid fertilizer and a preparation method. Background technique [0002] Lemon is an important species of citrus in the family Rutaceae. It is native to southwest China, southwestern Myanmar and the eastern part of the southern foot of the Himalayas. In the world's citrus planting industry, lemon occupies the third place. At present, there are more than 60 species in the world. countries grow lemons. However, lemon yellowing occurs frequently in lemon growing areas in my country. Lemon yellowing will affect its photosynthesis, resulting in reduced yield and quality of lemons, and premature senescence of the tree. In addition, the harm of Huanglongbing, root rot, gum flow, thrips and mealybug is also one of the main factors leading to the yellowing and dwarfing of lemons. Root rot and mealybugs mainly damage the ro...

Problems solved by technology

[0004] In order to solve the problems of low soil organic matter content, soil compaction, and imbalance of trace elements such as calcium, magnesium, potassium, and zinc in the soil, resulting in frequent occurrence of thrips, mealybugs, and root rot, the invention provides a water-soluble humic plant Use acid fertilizer to correct lemon yellowing, to solve the problem of lemon plants suffering from diseases and insects due to the lack of necessary trace elements, and finally increase lemon yield and improve fruit quality
