When we grow peas, we know it's earth-planted, so what's it like to grow pea seedlings without soil?
I. Cultivation facilities。
All used and idle houses, such as warehouses, closed balconyes, plastic sheds, etc., can be used for planting. Stereoculture of pea seedlings requires the installation of an iron slab. It's possible to grow in four seasons. The plastic plate used to plant peas is typically selected for black saplings with specifications of 60 cm, 24-25 cm wide and 3-5 cm high. Peas seedlings are colder, grow at 18-28°c and are about 80% wet, requiring weak light。
Ii. Cultivation techniques
1. Selection. There are many varieties that can be used to produce pea seedlings such as peas, peas, leather peas and purple peas. The variety of peas varies in nature and in growth, and it has been shown that peas and peas are the best growing fast and resistant with thick skins and small seed grains. At the same time, seeds of high purity, high gestation rates and not more than one year's shelf life should be selected for production。
Treatment. Seed impregnation is preceded by manual screening to remove moths, rots, deformities and other impurities, so as not to cause direct contamination during growth, such as decomposition, sprouts and poor growth. Then two to three times with hot water at 20-30°c。
3. Leaching. Insulated seeds can be used directly in cold water, 12-20 hours in spring and summer and autumn, 20-24 hours in winter and typically 2-3 times the weight of dry beans. Soaked to the seeds, the wrinkles disappear and the roots can be seen through the skin。
Seeding. The immersed beans will be gently rubbed with their hands from the slime attached to the skin, and the excess water will be immersed, and then evenly spread in the saplings (the plastic plate will be disinfected with potassium permanganate first and the newspaper or toilet paper will be used as the base). Each dish weighs about 500 grams and ends up flat-handed。
Management. Plated 6 to 10 plates of good beans, each with an empty disk of newspapers to keep it wet. Water sprayed every 10-12 hours (water sprayed with no water in the seedlings). In conjunction with water spraying, the top-down and back-up positions of the saplings are replaced and, when the sprouts grow as long as 2-3 cm, they should be placed on the ground or moved to the shelf for management。
Once the seedlings are released, the light in the production room is adjusted. Lights should not be too strong, so that peas seed cellulose is not formed too early to affect quality, but not too weak to grow too thin. Temperatures are controlled at around 22°c, with two to three water sprays per day, less sprayed during cloudy snow or lower indoor temperatures, and more sprayed at high temperature or humidity hours。
Collection。
When peas are grown up to about 15 centimetres, are grown in a coherent manner, and leaves are yellow, leaf-resulting or fully fat, they are harvested in due course. It may be marketed as a whole or sold with a sharp knife from 5-6 cm in the base。
