Before sowing germination spring sowing, the seeds should be treated, that is, soaked in warm water 50 °C ~ 60 °C for 30 minutes, then soaked with water for 20 to 24 hours, washed at about 25 °C under the temperature of germination, germination to keep moist, Rinse the seeds once a day with fresh water, and sow until the seeds break the white spots. For every 667 square meters, the amount of 6-10 kg is used.
The planted water spinach is suitable for soils rich in humus and moisture, strong branching, rapid growth, high planting density, high harvesting frequency, high yield and fertilizer resistance. Therefore, you should choose to grow sunny, fertile, watery fields.
Site preparation Planting in Lunan region of Shandong Province is generally conducted by means of live broadcasting, and sowing or sowing can also be used. Before sowing, plunge the soil, and apply 2500 to 3,000 kg of organic fertilizer per mu or 1500 to 2000 kg of human waste, 60 to 100 kg of plant ash, and mix thoroughly with the soil. Seeding is generally planted in dense rows with a spacing of 33 cm and soiled after sowing.
Fertilizer watering water spinach has a great demand for fertilizer and water, and in addition to applying base fertilizer, it also has to top-dress. When the seedlings grow to 5-7 cm, they should be fertilized and watered to promote seedlings. Afterwards, they should always be watered to keep the soil moist. Every time after picking, they must chase 1~2 times of fertilizer, topdressing with nitrogen fertilizer such as urea and ammonium sulfate. Cultivate weeds in time during growth.
Diseases and insect pests of the diseased pests are mainly white rust, cabbage caterpillar, and larvae of Spodoptera litura. The control of white rust can be controlled with 1:1:200 Bordeaux mixture or 0.2 Baume degree lime sulfur, or 65% zein zinc wettable powder 500 times, and sprayed once every 10 days to control the disease progression. . The control of cabbage caterpillar and Spodoptera litura larvae can be controlled by 20% speed killing and killing 8000 times of diced oil.
Timely harvested water spinach can be harvested at a plant height of 20-35 cm if it is harvested at one time. If it is harvested multiple times, seedlings can be planted at a plant height of 12 to 15 centimeters.
