Soilless cultivation and cultivation techniques of pea seedlings
First, soilless cultivation 5. Timely listed pea seedlings in the dark conditions of heat preservation and moisturizing, after 12 to 15 days, the seedling height can reach 15 to 18 cm. At this time, the shades should be gradually removed and the seedlings should continue to grow for 2 to 3 days under natural light. When the shoots are changed from yellow to greenish green, the waxy leaves are slightly waxy, and the stems are nearly square, they can be listed on the whole plate; they can also be quickly removed from the stem base of the sprouts and put into fresh-keeping bags for sale. Its output is generally 2 to 3 times the seeding rate. Second, nurturing technology Pea seedlings are rich in vitamins and phosphorus, calcium, iron and other substances. They can be fried and made soups. They are delicious and nutritious and are popular vegetables for consumers. Now introduce its cultivation method as follows: 5. Temperature, humidity, water and fertilizer management: The daytime temperature is controlled at 22～25°C before germination, 12～15°C at night, and the humidity is kept at 80%～90%. When the seedlings are two leaves and one Nepalese, 0.3% urea solution is used for watering. Water once every 7-8 days. 6. Timely harvesting when the seedling height 6 ~ 7 cm, with 6 leaves, seedling age about 30 days when the harvest can be listed.

Pea sprouts are sprouted vegetables, alias "Asparagus", which is pollution-free green food. Its delicate texture, clean scent, rich nutrition is a high-grade quality fresh vegetables. The use of soilless cultivation of pea seedlings, as long as the appropriate temperature, humidity, can be produced all year round, with less investment, quick results, and high benefits, welcomed by the majority of the people. The cultivation techniques are as follows.
1. Select the best kind of seedlings should be used to select high yield, fast growth, seedling thick, good quality pea species, such as white peas, Japanese Xiaoying, hemp, green peas and Taiwan peas. In order to ensure a higher germination rate, it is best to use fresh seeds that were produced or stored for one year, and care should be taken to remove such seeds as broken, insect bites, deformities, pods, etc. to prevent the occurrence of rotten seed and mildew during production. .
2. Immersion seed germination Before sowing, the selected seeds are placed in 55°C hot water and continuously immersed for about 15 minutes. When the water temperature drops to about 25°C, 500 times the fertilizer of Nong Pozan 1 is added and soaking is continued. ~ 6 hours; remove, wrap with a damp cloth, place germination at 20~25°C; when there is about 70% of the grain, you can sow.
3.Put the plastic seedling plate for cultivation or the iron plate welded with tinplate (the specifications are 60, 25, and 5 cm in length, width, and height, respectively) for the cultivation, and use 3%~5% bleaching powder or lime water first. Disinfect and rinse with clean water. Place two layers of clean white tissue or non-woven fabric in the pan so that it absorbs water evenly and maintains the temperature. Spread the seeds evenly in the pan, about 1500 grams per square meter (take dry seeds as the standard 0. Spray a warm water of 20°C after sowing, put the pan on the nursery stand.
4. Scientifically manage the upper shelves and cover them with black plastic film (it is also possible to use darkroom production) to encourage sprouts to grow in the dark. Every 6 to 8 hours, the film is sprayed with warm water of 20°C once to fully wet the mat without flowing. In combination with water spray, add 600-times Quexin Liquid Fertilizer and Nongbaozan No. 1 and other organic fertilizers at intervals of 3 to 5 times to ensure that the seedlings grow vigorously and increase the yield and quality. When water is sprayed, the seeds that do not germinate should be eliminated and mildew should be avoided. During cultivation, indoor air humidity should be maintained at about 85%, and the temperature should be 15~20°C (preferably 18~20°C. Slow growth below 12°C, and over 25°C cause leggy) to facilitate the normal growth and development of bud seedlings.
1. Selection of suitable varieties of Taiwanese dishes, Taiwan No. 3 peas, thick and fresh stems and leaves, is an ideal choice.
2. During the production period, the production cycle with the nutrition plate is short, generally 25 to 30 days can be harvested. In the middle and late October to late March of the following year, the off-season production of vegetables is better.
3. The specifications of the seedling tray are 60 cm in length and 40 cm in width, and 2 cm of fine sand is placed in the pan for watering before sowing.
4. Soak germination and seeding soaking in warm water at 50°C for 24 hours, and then wrap it in a warm place with a clean damp cloth, keep the temperature at 20～25°C, and sow the seeds evenly after sowing in the seedling tray and place the dish in the greenhouse Buds on the frame.
