Talking about the experience of cultivating Toona sinensis sprouts

Toona sinensis sprouts are green in color, tender and delicious, rich in aroma, rich in nutrition, and have the laudatory name of plant protein, which are deeply welcomed by consumers.

1. The suitable temperature for seed germination of Toona sinensis in production sites and facilities is 20 ℃-23 ℃, which stops growing above 35 ℃ and grows slowly below 12 ℃. It is suitable to be produced in greenhouse or other idle houses in spring and autumn, and in greenhouse and basement and other idle houses in winter. Using the way of three-dimensional substrate seedling plate cultivation, the cultivation rack can be made of angle iron, steel bar, bamboo and other materials, 1.6-2 meters high, divided into 4-5 layers, each layer spacing 40-50 cm. It is best to use a flat bottom perforated plastic seedling plate with a length of 60 cm, a width of 24 cm and a height of 4-5 cm. In addition, tools such as hoses, sprinklers, seed-soaking pools or plastic pots need to be prepared. Second, the improved varieties should be selected with strong fragrance, crisp and juicy, less fiber. At present, the ones with good quality are red oil Toona sinensis, red Toona sinensis and so on. The service life can be prolonged when stored in gunny bags or cloth bags and stored in ventilated, dry, dark and low temperature conditions. The fresh seeds are bright red and the seed coat is dull and fragrant. Sprouts should use seeds with a germination rate of 90%, a thousand-grain weight of more than 10 grams, and about 50 grams of seeds per plate. Third, cultivation techniques 1. Soaking seeds to accelerate sprouting. Remove impurities and shrunken seeds, rub off the wings, soak the seeds in warm water of 55 ℃, and keep stirring until the water temperature drops to about 30 ℃. After soaking for 12 hours, remove, rinse and drain the surface water of the seeds, put them in a constant temperature of 23 ℃ to accelerate germination, wrap them in a bean bag with a thickness of 5-6 cm, wash them with warm water 1-2 times a day, and sow seeds when the buds grow to 1-2 mm. two。 Sow seeds. Rinse the seedling plate or container in advance, spread a layer of paper at the bottom, and then spread a layer of 2.5 cm thick wet perlite (plus 50% water). Spread the budding seeds evenly on the substrate, about 50 grams per plate, and increase the amount of seeds if the germination rate is low. After sowing, cover 1.5 cm thick perlite, spray water immediately after covering. Can also plate bottom cushion two layers of cotton cloth direct sowing, but to stack about 5 days, wait for the bud to grow to 0.5-1 cm and then put on the cultivation rack. 3. Administration and Management. About 5 days after sowing, the bud protrudes from the substrate, and the water should be sprayed timely to keep the air relative humidity at about 80%. It can be watered with a soft hose sprinkler or sprayed with a spray can, evenly and appropriately, with no impact on the shoots and no stagnant water on the plate as the standard. The temperature should be controlled at 20 ℃-23 ℃ to block the sun and adjust the position of the seedling plate every 1-2 days to facilitate uniform growth. When the bud is 2-3 cm long, it should be ventilated every day. Harvest can be harvested about 18 days after sowing under suitable conditions of temperature and humidity. Qualified product standard: Hypocotyl is more than 10 cm long, cotyledons fully unfold, no new leaves, fresh and clean, no rotten roots and diseases, rich aroma. Pull up the roots and clean them and pack them on the market.
