Rice seedling cultivating technique for mechanical transplanting

Abstract

The invention belongs to the field of crop cultivating, and particularly discloses a rice seedling cultivating technique for mechanical transplanting. The rice seedling cultivating technique comprises the following steps of selecting seeds; preparing seedling cultivating soil; putting the seedling cultivating soil into a seedling tray to 80 percent of the capacity; uniformly distributing seeds to the seedling tray according to an amount of 62.5 mg-71.4mg per tray; covering the seedling cultivating soil onto the seeds, and maintaining the thickness to 0.4mm-1mm; horizontally placing the seedling tray in a rice field, wetting the seedling cultivating soil, draining water, and covering a thin film, wherein the thin film comprises a film layer I and a film layer II, the film layer I is directly coated on the seedling tray, and the distance between the upper surface of the film layer II and the upper surface of the seedling cultivating soil is 18mm-25cm; maintaining the wetting of the seedling cultivating soil in the seedling tray; when the seedling grows to 5cm, spraying a plant root and stem growth promoter once; preventing and curing the insects and the diseases one day before transplanting. The rice seedling cultivating technique has the advantages that by adopting the method, the germination time and the seedling emergence time can be shortened; the thickness of the seedling soil layer is uniform and consistent, the four corners of a rice block are vertical and square and are not lack of edges and corners, the seedlings are regular and uniform, the roots are intertwined, and the loosening is avoided after lifting.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a rice seedling raising technology suitable for mechanized transplanting. Background technique [0002] Mechanized rice transplanting is an efficient and simple cultivation method. In recent years, the technology of rice mechanized rice transplanting has been widely popularized, and seedling raising technology is one of the key technologies of machine transplanting. [0003] The traditional technology is to place the seedling tray on dry land or concrete ground to grow seedlings with tap water or prepared fertilizer and water. Although it is easy to operate, the germination and emergence time of seedlings is long, the root system of seedlings is underdeveloped, and there are missing corners and edges of seedlings. Scattered shortcomings. Contents of the invention [0004] The purpose of the present invention is to provide a kind of rice seedling raising technology suitable for...
