Mostly "two open to one cool", that is, two parts of boiling water to a cold water(cell trays), the water consumption is 4 to 5 times the seed. Pre-soak for 2 to 4 hours before soaking, then soak at a constant temperature for 5 to 30 minutes, and then cool off with cold water immediately after removal. When soaking seeds of melons (such as seedless watermelon, loofah, bitter gourd, etc.), the seed shell is thick and hard, and it is not easy to germinate(seed starter trays). When the soil surface is dry and whitish, it is poured in one time.
(wholesale square miniature succulent pots)The seed is pressed into the plug by artificial pressure(gallon nursery pots), and the depth is 2 to 2.5 times the diameter of the seed, and then covered with a matrix or vermiculite. Therefore, in the early spring and winter seedlings, in order to ensure the emergence rate and survival rate, a small arch shed can be built after the sowing, so that the seedbed is in the environment of the shed(wholesale greenhouse pots), and the temperature in the shed is 25~30 degrees, the relative humidity of the air is preferably 85% to 90%.
The seeds need to be treated before soaking so as to improve the germination rate and uniformity of the seed(gallon plant pot). After about 10 days of sowing, the seedlings are released. 3 to 6 days after emergence, pay attention to ventilation and temperature, and keep 20 to 25 degrees in the shed during the day. When the bed is dry and white, properly water in the evening(greenhouse supplies pots). According to the conditions of the seedlings, the weather and the humidity of the bed soil, it can be controlled in the evening or on a cloudy day.
(wholesale square miniature succulent pots)In addition, if there is a need for top dressing, the seedlings can be sprayed with 0.3% potassium dihydrogen phosphate and 0.2% urea aqueous solution(plug trays). There are mainly early rickets, blight, late blight, gray mold, blight, etc., and 1 or 2 kinds of pesticides such as mancozeb, carbendazim, metalaxyl, and agricultural streptomycin can be used(plastic grow pots). Rotation control; locusts can be controlled with lesbian, once and for all, and mites can be controlled with Uranus and Kruth.
After the sowing, it is required to have appropriate high temperature and high humidity(black plastic plant pots). When 60 to 70% of the seeds are emerged, the shed surface shade net should be removed and the small arch shed side film should be picked up. The main reason for the growth of seedlings is that the light is insufficient, and the second is that the temperature is too high(3.94inch plastic nursery pots). Usually, the number of watering should be reduced as much as possible to avoid the humidity of the seedbed.
The method of reducing the temperature(propagation tray), moisture or relative humidity of the environment and regulating the plant height is as follows: mechanical methods such as the dialing method, the vibration method and the increasing air flow method can all inhibit the growth of the plant. 1 to 2 days before planting, you should pay attention to the weather changes at any time(4.33inch plastic plant pots). If the humidity of the seedbed is too large after using the medicine, it is mainly used in warm water soaking and chemical dressing.(wholesale square miniature succulent pots)
It should generally be diluted with ash or fine soil(square nursery pots). In addition, it is also related to the excessive humidity of the seedbed and the excessive nitrogen fertilizer. In addition to increasing ventilation and enhancing light intensity, it should be noted that the seeding density should not be too large. It is necessary to increase the application of phosphorus and potassium fertilizer, control the night temperature, and timely seedling and planting(flat plastic tray). If chemical treatment is required, chlorophyll can be used for inhibition.
