Description

Technical Field

[0001] The invention relates to the technical field of liquid fertilizers, in particular to an organic mixed liquid fertilizer for promoting rapid growth of coconuts, and a preparation method and application thereof. Background Art

[0002] Coconut has high economic value, and all parts of the plant have uses. Unripe endosperm ("pulp") can be eaten as tropical fruit; coconut water is a delicious refreshing drink; mature coconut meat contains 70% fat, which can be used to extract oil, and can also be processed into various candies and cakes; coconut shells can be made into various utensils and handicrafts, and can also be made into activated carbon; coconut fiber can be made into brushes, carpets, cables, etc.; the trunk can be used as building materials; the leaves can be used to cover roofs or weave; the roots can be used as medicine; in addition to drinking, coconut water is a good promoter for tissue culture because it contains growth substances. In addition, the coconut tree has a beautiful shape and is an excellent tree species for greening and beautifying the environment in tropical areas.

[0003] Coconut is a perennial tropical woody crop. Its growth period can be roughly divided into the young stage, the initial flowering and initial fruiting stage, the full flowering and full fruiting stage, and the aging stage. Plants in different growth stages require different nutritional conditions. The young stage of coconut is divided into the coconut budding stage, the early stage of coconut seedling transplantation, and the late stage of coconut seedling transplantation. The main nutrition of coconut in the early stage of seedling transplantation is provided by coconut, and exogenous nutrition is also required. When the coconut seedlings are transplanted to the field, the coconut nutrition is almost exhausted, and external nutrition is required to grow normally. From the budding of coconut to the coconut seedling stage, the growth and development of its root system is very important, especially in the middle and late stages of young coconut trees when the coconut is almost exhausted. During the breeding of coconut seedlings, some fruits have stagnant root growth and development, slow growth, and rot caused by pests and diseases. These problems cause the coconut seedlings to rapidly weaken their ability to absorb nutrients from the outside world and coconut, which causes the coconut seedlings to lack nutrients and reduce their ability to resist diseases, directly or indirectly leading to the appearance of physiological chlorosis of coconut seedlings, withering of the core of coconut seedlings, and even dead seedlings. Coconuts also need a lot of nutrients from flowering to fruit development. Only by supplying the required nutrients can the coconut yield be guaranteed. Therefore, coconuts need to be fertilized with suitable liquid fertilizers to promote growth.

[0004] The coconut liquid fertilizer in the prior art cannot meet the various nutrient requirements of coconut and does not significantly improve the growth of coconut.

[0005] Based on this, the present invention is proposed. Summary of the invention

[0052] (4) The present invention uses old coconut leaves and stems as raw materials to extract active substances, and the active substances are crude wood vinegar; the crude wood vinegar obtained by extraction can promote the development of coconut root system and provide organic nutrients required for coconut growth. In addition, because it contains many phenolic substances, it can kill bacteria, disinfect and avoid pests, and has disinfection and insect repellent effects.

[0053] (5) Carbendazim is added to the liquid fertilizer of the present invention, which has bactericidal and insect-proof effects and protects the root system of young coconut trees from being attacked by pests.

[0054] (6) A certain amount of boric acid and sea salt are added to the liquid fertilizer of the present invention because coconut growth requires more Na, Cl, and B elements than other crops. A certain proportion of boric acid and sea salt are added to the formula to supplement the Na, Cl, and B nutrients required for the growth of young coconut trees.

[0055] (7) Peptide amino acid fertilizer is added to the liquid fertilizer of the present invention to supplement amino acid nutrition, promote rapid growth of coconut and improve coconut fruit quality.

[0056] (8) The preparation process of the fertilizer of the present invention is simple, and waste resources are fully utilized to turn waste into treasure, and the cost is low and the production efficiency is high, and a good growth environment and conditions are provided for coconut. The organic waste is rationally utilized, and the processing waste of the factory is disposed, and technical support is provided for the improvement of the rural ecological environment, and good economic benefits, social benefits and ecological benefits are achieved.
