Hou Xiying Village, Dezheng Town, Wei County, Hebei Province promoted the planting pattern of “Spinach-Brassica oleracea†three-year-old leeks, spinach, cabbage shed cultivation, and welsh onions. The advantage of this planting mode is that it is not only beneficial to land fertilization and deep plowing, but also makes full use of the light and heat resources, increases the multiple cropping index, avoids double cropping, and reduces pest and disease damage. This kind of mouthwash arrangement, spinach is listed on New Year's Day and Spring Festival, cabbage is listed on May Day, and green onions are listed on the Mid-Autumn Festival and National Day. All of them are high season prices for vegetables, and the economic benefits are significant. This model generally produces 1500 to 1700 kilograms per kilogram of spinach, with prices ranging from 3 to 3.5 yuan per kilogram, 1800 to 2,000 kilograms per kilogram of cabbage, 1.5 to 1.6 yuan per kilogram, 3800 to 4000 kilograms per hectare, and 1.2 to 1.5 yuan per kilogram. The annual output value of mu is more than 10,000 yuan. This planting model has been promoted in Wei County, more than 100,000 acres, welcomed by vegetable farmers. The outlines of the mouthwash arrangement and planting techniques of this model are as follows:
spinach
In late August, after the crop is harvested, Mushi quality organic fertilizer 5000 kg, nitrogen, phosphorus and potassium (potassium sulfate) three-element compound fertilizer 70 to 80 kg, with appropriate amount of zinc, boron, iron and other trace element fertilizer, fine tillage. After the site preparation, press the 2.5 to 3 m area to make a flat rake. The middle one is used for easy watering. Leave 50cm space between the belt and the belt to prepare for inserting the arch frame and buried plastic film. Sowing time is late September. The large-leaved spinach was used as an excellent variety, drilled at a spacing of 12 cm, watered in time after sowing, and 2 to 3 leaves of seedlings emerged after emergence, with a spacing of 2 to 3 cm. In November, the skeleton of the arch was inserted and covered with a plastic film. Vents were left at both ends of the arch and were opened for ventilation during the day and closed at night. When spinach grows to 4 to 5 leaves, urea is applied once to 25 kg per mu. Later, depending on soil moisture, timely watering, small water to be poured, flood irrigation is prohibited, so that excessive humidity caused by the shed. Clean the dust on the shed film in time to facilitate light transmission and increase the temperature inside the shed. The major diseases of arch shed spinach are downy mildew and viral diseases. The market was harvested from late November to next January.
Cabbage
In mid-December, seedlings were planted with early-maturing, disease-resistant and high-yield varieties, such as Primula and 8398.
After the spinach is harvested, the arch shed is not removed and the sheds are cleaned in time to bring out the shed. Mushi diammonium phosphate 40 ~ 50 kg, shallow ploughing, Fuping back preparation. In mid-February, the planting colonies were planted with a spacing of 40 cm and a spacing of 25-30 cm. After planting watered in time, after depending on soil moisture watering. During the rosette period, urea is applied once to 25 to 30 kg per mu. The main diseases and pests of cabbage include aphids, cabbage caterpillars, beet armyworm and black rot, etc., and the spraying of pesticides should be promptly controlled. Harvest from late April to early May.
Onion
In the last ten days of last year, seedlings were exposed in the open field, and high-yield varieties of Zhangqiu green onions were selected.
After the cabbage was harvested in mid-May, the shed's skeleton and film were removed, the field's rotten vegetables were cleaned, and green onions were planted. Mushi organic fertilizer 5000 kilograms, high-potassium three-element compound fertilizer 70 to 80 kilograms, with the appropriate amount of zinc, iron, boron and other fertilizers, deep plowing, planting trenches, row spacing 60 to 70 cm, spacing 4 to 5 cm. Before the planting, the onion seedlings should be selected and graded in a timely manner. The onion seedlings of the same level should be planted together to prevent seedlings from sprouting. Watering in time after planting, and then timely watering according to soil moisture. Three or four times of cultivating soil in the process of growing onion shall be carried out to ensure lodging resistance and light blue porcelain. Welsh onions are high-potassium vegetables. During the growth process, potassium sulfate fertilizer should be applied 1 to 2 times, and Mushi 20 to 25 kg. The combination of pest control and pesticide spraying 0.3% potassium dihydrogen phosphate solution 2 ~ 3 times.
The pests and diseases of green onions are mainly thrips, spotted fly, beet armyworm, downy mildew, purple spot, root rot, etc., and timely spraying control. The onion harvest period is longer and can be flexibly controlled according to market conditions and export arrangements.
