Method for floating seedling breeding in sorghum paddy field

Abstract

The invention discloses a method for floating seedling breeding in a sorghum paddy field. The method comprises the following steps of (1) selecting seedling breeding fields, (2) selecting seedling breeding trays and base materials, (3) treating seeds and the seedling breeding trays, (4) building seedling ponds, (5) preparing nutrient solution, (6) loading base material into trays and seeding; (7)covering films or sunshade nets; (8) seedling management, and (9) suitable age transplanting. According to the method for floating seedling breeding, the seeding ponds are easy to built, the investment is small, the use of plastic film is greatly reduced, surplus fertilizer can be used for planting rice, water leakage is not prone to occurring, damage from livestock is not prone to occurring, andmany restrictive factors of the large area application of floating seedling breeding in production are broken. Compared with an existing conventional broadcast sowing technology, the method has the advantages of saving seedbeds, comprehensive nutrition, regular seedling emergence, robust growth, shortening the age of seedlings, simple management, convenient transplanting, lowering costs, and reducing susceptibility.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a method for raising sorghum seedlings by floating in paddy fields. Background technique [0002] Conventional sowing seedling raising technology has the advantages of large water demand during transplanting and is easy to be killed, and the greening period is long. In sorghum planting areas, seedlings are susceptible to diseases at the seedling stage, and the soil requirements for growing strong seedlings are also high. Sandy loam and vegetable fields are better. Often affected by these factors, conventional sowing seedlings in sorghum planting areas often cause weak seedlings, anthracnose and head black disease at the seedling stage, resulting in severe production reduction. [0003] Existing floating seedling raising technology is divided into big shed and small shed floating seedling raising. The effect of greenhouses is good, but the cost is too high to l...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to: in view of the above-mentioned prior art, the effect of the greenhouse is good, but the cost is too high to limit its large-scale application. The small arch shed has a large labor input for floating seedling cultivation and building ponds, and the price of thick plastic films is high, and it is easy to be damaged by livestock to cause water leakage, etc. Insufficient, provide a kind of method of sorghum paddy field floating seedling raising
