Floating-tray seedling raising method for autumn Enteromorpha prolifra

Abstract

The invention belongs to the technical field of Enteromorpha prolifra planting and particularly relates to a floating-tray seedling raising method for autumn Enteromorpha prolifra. The method comprises the steps of substrate preparation, sowing, after-sowing management and field planting. Compared with the prior art, the method disclosed by the invention has the following advantages that a substrate has relatively high fertilizer and water retention capacity and is good in permeability, and the rapid germination of seeds is facilitated due to the matched action of the substrate and a sowing method; through controlling seedling raising conditions and methods, the time for seedling raising can be shortened by 4 to 6 days, the rate of seedling emergence and the rate of sound seedlings are increased, the disease resistance is enhanced, and the consumption of pesticides is lowered; and the injury to young seedlings is reduced during field planting, the survival rate is high after field planting, and the management method is simple, so that the method is applicable to popularization.

Description

technical field [0001] The invention belongs to the technical field of dry moss planting, and in particular relates to a method for raising seedlings on a floating tray with dry moss in autumn. Background technique [0002] Dry moss likes cool, cool and sunny climatic conditions. It can be planted in spring and autumn, but there are obvious differences in yield and quality. When planting in autumn, with sufficient sunshine and appropriate amount of rain, the relative quality is relatively high and the quality is good. Due to the high temperature and large evaporation, the dry moss seeds are small, the top soil capacity is weak, and the seedling emergence is slow. It is necessary to keep the border moist to facilitate the emergence of the seedlings. The soil humidity and other environmental conditions need to be strictly controlled before and after emergence. The operation is relatively It is cumbersome, but the emergence rate is low, and the survival rate after the seedling ...

Problems solved by technology

[0002] Mosses like cool and sunny climates, and can be planted in spring and autumn, but there are obvious differences in yield and quality. Planting in autumn, with sufficient sunshine and moderate rainfall, has relatively high quality and good quality. When sowing, Due to the high temperature and large evaporation, and the dry seeds of the moss are small, the ability to top the soil is weak, and the emergence is slow. It is necessary to keep the furrow surface moist to facilitate the emergence. Before and after emergence, the soil humidity and other environmental conditions need to be strictly controlled. The operation is relatively It is cumbersome, but the emergence rate is low, and the survival rate is low after the seedlings are established. Therefore, further research on the cultivation of strong seedlings of dried moss is needed
