Bitter vegetable, also known as amaranth, is a perennial wild vegetable that people like to eat. It not only has high nutritional value, but also has medical functions such as heat removal and detoxification. Bitter vegetables have strong adaptability and can grow in the fields and roadsides. If it is artificially cultivated in a plastic greenhouse, the yield per mu can reach more than 1,000 kg in 40-50 days in the morning in the open field. Its cultivation techniques are as follows:

1. Sowing time The sowing adaptation period of bitter vegetables grown in greenhouses is from late July to mid August. Too late, the seedlings are small, the cold and drought resistance is low, and the yield is reduced. As the bitter vegetable seeds have no dormant period, they can be sown for production in the year of harvest. For the first planting, wild bitter cabbage seeds can be collected.

2. The sowing method is beneficial to the growth of bitter vegetables. It is necessary to choose loose and fertile plots for seeding, deep ploughing before sowing, combined with 3000 kg of organic fertilizer per acre of land preparation, and then make hoe according to the area of the shed. Rice, 7 centimeters of small grooves on the crotch surface, 12 centimeters of groove distance. Drain the bottom water, soak the seeds in the trench after water infiltration, and cover the trench with fine soil. Cover the surface with a plastic film for insulation, and cover the film with grasshoppers to prevent the high temperature from affecting the germination. Generally, the seeding amount per square meter is 3 grams.

3. Field management can emerge within 7-8 days after sowing. The root system of the seedlings that have just been unearthed is weak. It is necessary to keep the soil moist by spraying water to prevent drought seedlings from loosening the soil in time after 2-3 days of watering. Water evaporation can promote root growth. Weeds are the main factor affecting the normal growth of seedlings, so they must be removed at any time. After the beginning of autumn, the weather is cool and bitter vegetables grow more vigorously. In order to promote its strong root system and accumulate more nutrients, it is necessary to combine irrigation with water to chase thin manure once, 1000 kg per mu.

4. Second year management

Shed: In order to prevent the bitter vegetables and the morning market from being damaged by freezing, it is generally necessary to cover the film in March, mid and March. After the soil thaws, weed off the dead leaves and weeds on the ground. When the 5 cm soil reaches 4--5 ° C, the bitter cabbage will start to sprout and turn green.

Fertilizer water: If there is little snow in winter and soil moisture is not good, you should irrigate water 3 to 5 days after returning to green, which should be able to soak through 15 cm of soil layer. If the amount of water is too large, it will reduce ground temperature and affect growth. , Irrigation water 1 to 2 times before harvest can meet the needs. Bitter vegetables are mainly leaf-eating and require more nitrogen. In order to obtain high yield, a foliar topdressing is required in the 2--3 leaf stage, and a 0.5% urea solution is sprayed.

Humidity: Bitter vegetables like cold climate conditions, the temperature in the shed is too high to grow, so when the shed temperature reaches 25 , timely ventilation and cooling to ensure that the temperature is around 20 . When the leaves grow above 4 cm, they can be harvested and marketed
