Xia Lu to pick vegetables cultivation measures

Amaranth, alias green squid, red leeks, wild locust, rice bran, is an annual vegetable that feeds on young leaves of the genus Amaranth. Native to China, it is one of the main leafy vegetables in summer.

First, choose the variety. Xia dew should choose strong heat-resistant, drought-resistant, strong resistance to diseases and insect pests, high yield and quality of large-leaved red amaranth, round-leaved leek and red leafy leek. 1 big leaf red leeks. The whole plant has 14 leaves, large leaves, long oval, leaf margin near full, deep purple, leaves the periphery of green; stems light green, tender stems, leaves thick meat tenderness, should be cooked food, unique flavor. About 40 days after sowing can be harvested. General production of 2,500 kg of 667 square meters. 2 round leaf leek. There are 15 leaves in the whole plant. The leaves are green on the front and green on the back. The petioles and stems are green or dark purple. There are white short hairs on the stems and leaves. Tender stems and leaves should be soft and cooked. In the warm, water and fertilizer conditions, the rapid growth, after sowing more than 20 days to harvest. General production of 667 square meters 2000 kg. 3 pointed red amaranth. The whole plant has 12 leaves, the leaves are narrow and long, the petioles and stems are purple, and the leaves and stems are covered with white short hairs. Tender strains are slightly thicker and contain more fiber and should be cooked. General 667 square meters produce 1500 kilograms.

Second, to do sowing. Choose a flat land, convenient irrigation and drainage, fertile sandy loam or clay loam, and alkaline soil. After the harvest of the former crop, the soil was timely squeezed and 2,000 kg of fertilizer was applied per 667 square meters, and 50 kg of diammonium phosphate. After making a deep roll, a 1.5-meter-wide flat sheet was made. Live broadcasts are generally used to harvest seedlings for consumption. Seed sowing in stages from May to late June. Use sowing, planting 1 kg per 667 square meters. After sowing, the cover soil was 0.5 cm thick, and the head water was poured after compaction.

Third, field management. Viola is a wild vegetable that is easy to manage and can often keep the field moist. Summer sowing leeks 3 to 6 days emergence, timely weeding after emergence, and strengthen water and fertilizer management to keep the soil moist. In the high temperature period in midsummer, it is necessary to cover the shade net to cool and moisten, so as to cover the night and create a suitable temperature environment conducive to the growth of leeks, which will help improve the output and improve the quality. From sowing to two true leaves, choose the top dressing for the first time on a sunny day, the second top dressing after about 12 days, and the top dressing for the third time after the first time. Watering in time after top dressing; each time after harvesting, it is top dressing 1 time. The basal fertilizer is sufficient and no fertilizer may be added during growth.

Fourth, control pests. Leek has strong disease resistance, and the main disease is white rust and the pests are aphids. White rust prevention and control, can be selected in the early onset of spraying 50% arsenic copper wettable powder 700 times, or 64% antiviral WP 500 times, or 60% methylaluminum copper wettable powder 600 times liquid control. Control locusts, 40% dimethoate 1200 ~ 2000 times, or 2.5% Kung Fu EC 4000 times spray control.

Fifth, timely harvest. 45 to 50 days after sowing, the seedling height 12 to 15 cm, 5 to 6 leaves when the first harvest, that is to say, pull some dense plants. In 20 days, when the plant height is 20 to 25 centimeters, the second harvest is made by leaving 5 centimeters at the base. After the collateral germination grew to about 15 cm, the third harvest was performed.
