How to cultivate spinach seedlings? How to deal with spinach seeds before sowing? Also ask the netizens who know to help introduce the treatment methods of spinach seeds before sowing and the cultivation methods of spinach seedlings, which are listed in detail below for netizens' reference. Spinach seed treatment before sowing: spinach seed soaking: spinach seed because the epidermis is attached to a layer of gum, so the conventional sowing is slow and irregular, so spinach seeds need to be soaked before sowing. The original solution of hydrogen peroxide was mixed with water at the ratio of 1:4 and fully stirred to prepare an aqueous solution of hydrogen peroxide of 20% and 25%. Put the prepared aqueous solution of hydrogen peroxide in a container and pour it into the seeds while stirring with wooden sticks so that the seeds can absorb water evenly. If the temperature is lower than 20 degrees Celsius, the seed soaking time needs 100 minutes to 120 minutes; when the temperature is above 20 degrees Celsius and below 30 degrees Celsius, the seed soaking time is 60 minutes to 90 minutes; when the temperature is above 30 degrees Celsius, the seed soaking time is 30 minutes to 50 minutes. Spinach seed soaking points for attention: 1. Before soaking the seeds with hydrogen peroxide solution, the self-retained or purchased vegetable seeds should be dried in the sun for 4-6 hours on a sunny day, and the sundries and unfull seeds should be removed. 2. The seeds that have been soaked and germinated should be sterilized with chlorothalonil water solution. 3. The seeds should be sowed in time after soaking, accelerating germination and sterilization. Germination of spinach seeds: remove the seeds from the aqueous solution of hydrogen peroxide, then rinse with clean water for 3-4 times (filter water while rinsing), filter the water and cover it with a wet cloth to accelerate germination. Cultivation of spinach seedlings: after spinach sowing, the seedlings were fastened in the greenhouse, and the seedlings were usually planted in two waters, and then watered 10 days after emergence. After the two true leaves of spinach were unfolded, the leaf number, leaf weight and leaf area increased rapidly, and the soil was moist before 3-4 leaves. 25kg ammonium bicarbonate per mu was applied, and the seedlings that were too dense were hoed once, and water was properly controlled. Pay attention to heat preservation before and after "Lesser Snow" in November, and release air and dehumidification at noon. In order to appear on the market ahead of time, a small arch shed can be set up during the overwintering period. spinach begins to turn green after late January and should be released gradually. The suitable greenhouse temperature is no more than 25 ℃. When the temperature is high, the spinach plant is thin and weak, the leaves curl, the quality decreases and the yield decreases. And pay attention to watering the green water, apply 25 kilograms of ammonium bicarbonate with the water, and then irrigate once every 7-10 days, and fertilize again.
