Facility efficient ecological safety lotus root and loach planting and breeding method

Abstract

The invention discloses a facility efficient ecological safety lotus root and loach planting and breeding method. The facility efficient ecological safety lotus root and loach planting and breeding method includes selecting earth which meets pond requirements; 2), digging pond ditches, in other words forming foundation culture ponds, tamping pond bottoms and pond walls, forming water inlets and drainage ports in opposite corners of two ends of each foundation culture pond, and forming the annular ditches in the peripheries of the ponds; 3), laying non-woven surfaces, in other words, laying non-woven fabrics at the pond bottoms, covering the four walls of each pond with the corresponding non-woven fabrics, covering the ponds with slit, applying sufficient base fertilizers, constructing greenhouses on the peripheries of the ponds and increasing the temperatures of the insides of the greenhouses; 4), cultivating lotus roots; 5), planting the lotus roots in fields in due time; 6), releasing loaches, in other words, feeding water into the ponds until the depths of the water in the ponds range from 30cm to 40cm and completely constructing the culture ponds. The pond requirements on the earth include sufficient sunlight and water sources, warmth, ventilation, convenience in drainage, irrigation and transportation and zero toxic and harmful substance emission, and soil on the earth is preferably clay with rich humus. The depth of each ditch ranges from 60cm to 80cm, and the width of each ditch ranges from 20cm to 30cm. The depth of the silt which covers each pond ranges from 25cm to 40cm. The planting density of the lotus roots is proper so that the plant row spacing of early-maturing varieties is 1.0X2.5 meters, and the sowing quantity is 150 kilograms per mu. Each kilogram of loaches which are released into the ponds includes 200-300 loaches.

Description

technical field [0001] The invention relates to a high-efficiency and ecologically safe cultivation method of protected lotus root-loach, which belongs to the field of cultivation. Background technique [0002] With the improvement of people's living standards and the development of international trade, the demand of the vegetable market has undergone tremendous changes. In order to meet the needs of the new situation, my country's vegetable industry has rapidly developed from a "production type" to a safe and high-quality "convenience type". Since vegetable production is a high-tech and technology-intensive industry, which has the competitive advantage of participating in world free trade, vegetable cultivation in my country has sprung up in the past ten years and has become the preferred project for export agriculture. The export market has expanded from the traditional Japan, South Korea and Hong Kong, Macao and Taiwan to many countries in East Asia, South Asia, Europe an...

Problems solved by technology

However, due to the poor information of growers, especially the failure to apply new varieties and technologies in time, the production methods are backward, and the quality and production skills of farmers cannot meet the requirements of the development of facility vegetable production.

With the progress of society, the intensification of market competition, and the advent of the era of commodity economy with extremely rich agricultural and sideline products, people have higher requirements for the taste, flavor, internal quality, food safety, and pesticide residues of food. , only high quality can stimulate consumers' desire to buy. The products produced by the original simple production equipment and extensive management mode can no longer meet the requirements of consumers. Quality is especially important for vegetable exports.
