Special fertilizer for water grass for rice-fish complex planting and breeding

Abstract

The invention discloses special fertilizer for water grass for rice-fish complex planting and breeding. The special fertilizer is prepared from the following raw material components in parts by weight: 20 to 30 parts of potassium sulfate type slow release fertilizer, 8 to 24 parts of humic acid, 18 to 25 parts of ammonium sulfate, 15 to 20 parts of calcium magnesium phosphate fertilizer, 4 to 8 parts of diaminoferric xanthohumate, 6 to 12 parts of attapulgite, and 6 to 10 parts of composite root growth promoting agent. According to the special fertilizer for the water grass for rice-fish complex planting and breeding provided by the invention, growth characteristics and fertilizer requirement laws of the water grass for rice-fish complex planting and breeding are combined, so that accuratenutrition is provided for the water grass, the water grass can quickly grow roots and grow continuously and are promoted to grow new roots and grow new buds, the water grass is developed in root systems and robust in stems, a soil holding force of the water grass is improved, the root amount is increased, the root taking vitality of the water grass is improved, the resistance of the water grass can be also improved, and the requirements of a rice-fish industry on the water grass are met.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to an environment-friendly, slow-release and enhanced shrimp and crab breeding pond water and weed fertilizer. Background technique [0002] Rice-fishing compound planting and breeding is to comprehensively plant and raise rice, fish, shrimp, crab, etc. through corresponding technologies. On the premise of stable rice production, it can greatly increase the economic benefits of rice fields and farmers' income, improve the ecological environment of rice fields, and have the functions of stabilizing grain and promoting economic growth. A new model for the development of modern ecological circular agriculture with multiple functions such as fishing, efficiency enhancement, quality improvement, and ecology. Planting aquatic plants has become one of the most important technical measures to carry out rice-fish aquaculture. If the aquatic plants are good, the fish in rice fields will...

Problems solved by technology

[0003] Quicklime clear ponds are generally used before aquatic plants are planted, but the alkalinity of the ponds is too high, causing the aquatic plants to turn yellow after planting in winter and spring, the leaves fall off, and the surface attachments on the stalks increase; Slow, if the fertilizer supply is unreasonable, it will often lead to weak growth of aquatic plants. Although the method of direct application of urea by rice field farmers can promote the growth rate of aquatic plants, it will cause damage to the shrimp and crabs in the rice fields.

Secondly, some rice-fishing compound cultivation uses a very small amount of compound fertilizer to promote the growth of aquatic plants. This type of fertilizer often cannot fully meet the growth characteristics of aquatic plants and cannot meet the law of their fertilizer needs, resulting in slow growth, rapid aging, and even rot of aquatic plants. , cannot guarantee the health and stability of the aquatic plant ecological community throughout the breeding cycle, thus affecting the normal growth and development of shrimp and crabs

Furthermore, due to its own shortcomings and improper use of fertilizers for aquatic plants, the utilization rate is low and water pollution is becoming more and more serious.

Moreover, during the cultivation, the aquatic plants are damaged by the activities of the river crabs, causing the stems and leaves to be strained and broken, resulting in plant injury and affecting the normal growth of aquatic plants.
