Particles special for fertilization and feeding integrated rice field shrimp culturing and preparation method and application method thereof

Abstract

The invention relates to particles special for fertilization and feeding integrated rice field shrimp culturing and a preparation method and application method thereof, and belongs to the technical field of rice field planting, culturing, fertilization and feeding integration. The particles are prepared by mixing 50-500 parts of crop waste, 5-30 parts of nitrogen fertilizer, 10-100 parts of tea meal, 10-100 parts of bone meal and 5-50 parts of river pond mud. The particles special for fertilization and feeding integrated rice field shrimp culturing and the preparation method and application method thereof not only completely replace rice fertilization and shrimp feeding of rice field shrimp culturing, but also promote rice field soil improvement and water nutrient enrichment and environment disinfection and trash fish elimination, and thus labor and material saving, quality improvement and efficiency improvement of the planting and culturing mode of rice field shrimp culturing are achieved.

Description

technical field [0001] The invention belongs to the technical field of rice field planting, breeding, fertilization, and feeding integration, and specifically relates to a special granule for rice field shrimp farming integrated with fertilizer feeding, and a preparation method and an application method thereof. Background technique [0002] In recent years, the rice field shrimp farming model has grown rapidly in the southern rice planting area, which not only realizes the efficient use of resources, but also brings considerable economic benefits to farmers. According to statistics, the co-planting model of shrimp and rice can generally produce more than 600 kilograms of rice per mu, 100-150 kilograms of crayfish, and a net income of more than 3,000 yuan, which is more than three times the net income of simple rice cultivation. Studies have shown that lobsters can reduce planting costs while eliminating weeds. Lobster feces can provide some nutrition for rice, thereby reduc...

AI Technical Summary

Problems solved by technology

Due to the low income of rice planting, there have been fewer and fewer farmers planting rice in recent years, and the income of crayfish is considerable. Therefore, most farmers tend to raise shrimp and rice together. Some farmers even turn rice fields into lobster pits. Paddy field ecological environment has produced many negative impacts

Because the benefits of raising crayfish are much higher than planting rice, the phenomenon of farmers gradually re-cultivating crayfish and neglecting rice, and even changing the structure of rice fields, turning rice fields into shrimp pits, resulting in a reduction in rice planting area year by year

In addition, in order to ensure the yield and quality of crayfish, the rice yield in the shrimp paddy field was significantly reduced
