A method for raising seedlings by floating in sorghum paddy fields

Abstract

The invention discloses a method for floating seedling raising in sorghum paddy fields, which comprises the following steps: (1) selecting a seedling raising field; (2) selecting seedling raising trays and substrates; (3) treating seeds and seedling raising trays; (4) building seedling raising ponds; 5) Preparation of nutrient solution; (6) Substrate packing and sowing; (7) Covering film or sunshade net; (8) Management at seedling stage; (9) Transplanting at the right age. The floating seedling raising method of the present invention is easy to create seedling ponds, requires little investment, and greatly reduces the use of plastic films. The remaining fertilizer can be used for planting rice, and it is not easy to leak water or be damaged by livestock, which breaks the large-scale production of floating seedling raising. There are many limiting factors in the application. Compared with the existing conventional sowing technology, it has the advantages of saving seedbeds, comprehensive nutrition, neat emergence, robust growth, shortened seedling age, simple management, convenient transplanting, reduced costs, and reduced disease 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
