Bitter vegetables cultivated in greenhouses, also known as basic vegetables, are perennial wild vegetables that people like to eat. They not only have high nutritional value, but also have medical functions such as clearing away heat and toxic materials. Sowthistle has strong adaptability and can grow in fields and roadsides. If the plastic greenhouse is cultivated artificially, it will be listed 40-50 days earlier than the open field, and the yield per mu can reach more than 1000 kg. Its cultivation techniques are as follows:
1, and the sowing adaptation period of sowthistle cultivated in greenhouse is from late July to mid-August. Too late, the seedlings are small, the cold and drought resistance are low, and the yield is reduced. Because sowthistle seeds have no dormancy period, they can be sown and produced in the year of seed collection. Wild sowthistle seeds can be collected for the first planting.
2. Sowing methods In order to be beneficial to the growth of bitter vegetables, loose and fertile plots should be selected for sowing, and deep ploughing should be carried out before sowing. Combined with soil preparation, 3000 kilograms of organic fertilizer was applied to each mu of land, and then the border was made according to the shed area. Generally, the width of the border is 1 m, and there are seven 8 cm deep ditches on the border, with the ditch spacing of 12 cm. Pour bottom water, sow seeds in the ditch after seepage, and cover the ditch with fine soil. Cover the frame with plastic film to keep warm, and cover the film with grass stalks to prevent sunlight and high temperature from affecting germination. Generally, the sowing amount per square meter is 3 grams.
3. Seedling can emerge 7-8 days after sowing. The newly unearthed seedlings have thin roots, so water should be sprayed to keep the soil moist to prevent dry seedlings from dying. After watering for 2-3 days, the soil can be loosened in time, which can not only inhibit soil moisture evaporation, but also promote root growth. Weeds are the main factors affecting the normal growth of seedlings, and should be pulled out at any time. After beginning of autumn, the weather was cool and bitter vegetables grew vigorously. In order to promote their strong roots and accumulate more nutrients, it is necessary to catch up with dilute manure with irrigation, with an area of 1 1,000 kg per mu.
4. Management in the second year
Buckling shed: In order to make bitter vegetables go on the market as soon as possible and not suffer from freezing injury, it is generally necessary to build a shed in early and middle March. After the soil is thawed, carry away the dead leaves and weeds on the ground. When the local 5 cm soil reaches 4-5 degrees Celsius, bitter vegetables begin to sprout and turn green.
Fertilizer water: If there is little snow in winter and the soil moisture is not good, water should be poured once every 3-5 days after turning green, subject to the fact that 15 cm soil layer can be soaked. Too much water, the ground temperature decreases and the growth is affected. In the future, according to the soil conditions, water should be poured twice before harvesting to meet the needs. Bitter vegetables mainly eat leaves and need more nitrogen. In order to obtain high yield, foliar topdressing and spraying 0.5% urea solution are needed at 2-3 leaf stage.
Humidity: Bitter vegetables like cold climate conditions, and the high temperature in the shed is not conducive to growth, so when the temperature in the shed reaches 25 degrees Celsius, it should be ventilated in time to ensure that the temperature is around 20 degrees Celsius. When the leaves grow to more than 4 cm, they can be harvested and marketed.
Erya Cao Shi XIII and Tea Bitter Vegetables. Sonchus oleraceus is a perennial herb of Compositae.
