Sorrel
Background: a perennial plant widespread in Europe and North America. In nature there are more than 150 of its species, but they cultivate only selectively improved form - sorrel ordinary.
Requirements: sorrel - cold-resistant plant. The most favorable temperature for vegetation of plants is 15-16 ° C.The plants tolerate slight shading, so they can be grown in row-spacing. Sorrel equally well grows on all types of soil, including peat bogs, with a slight acidity. The best for him are weakly acidic water-permeable soils rich in organic substances. In one place, sorrel is grown for 3-4 years, then the plants sprout and require renewal. When preparing the plot in the spring, 8-10 kg / m2 of compost or decomposed peat, 10-12 g / m2 of ammonium nitrate, 20-25 superphosphate and 12-15 g / m2 potassium salt are given in the spring. In autumn, after harvesting the predecessor, the soil is dug and fertilized.
Ingredients: leaves rich in protein, potassium and iron salts, vitamins A, C, B1, B2, PP, contain valuable organic acids - malic, citric, oxalic. Especially a lot of oxalic acid accumulates in old leaves, in spring there are more apple and citric acids in the leaves.
Cultivation: seeds are sown to a depth of 0.5 cm, rows with rows between 40-45 cm or two-row ribbons with a distance between them of 40-45 cm, and between rows - 18-20 cm.
Sorts
Bellevsky - earlysprouts before the start of collection takes 42-45 days).The leaf plate is large, fleshy, ovoid in shape. Length 13-15 cm, width 5-10 cm. The petioles are thick. Leaves are light green. Large leaf - early maturing( 36-43 days).The leaf plate is light green, oval-elongated, not very acidic. Length 10-15 cm, width 6-10 cm
Odessa 17 - early maturing( 40-45 days).Medium-resistant, relatively drought-resistant. The leaf is elongated, oval. The length of the plate is 12-16 cm, the width is 6-8 cm, the length of the petiole is 11-23 cm, and the thickness is 0.5 cm. The petioles are slightly colored in violet. The leaf is green. Broad-leaved - early maturing( 45 days);winter hardy. Leaf plate is not large, ovoid in shape. Its length is 12-15 cm, width 6-8 cm, length of petiole 11-24 cm, width 0.4-0.6 cm. Color of leaf is green.
Care: after sowing the soil is mulched with peat or humus. Shoots are thinned, leaving a distance between plants 4-5 cm, with narrow row spacing - 8-10 cm. Over the summer 3-4 loaves are carried to a depth of 4-5 cm. For the second year, sorrel is fed using 8-10 g / m2Ammonium nitrate and superphosphate and 10 g / m2 potassium salt. In hot weather, plants are watered. In addition, remove the flowering shoots.
Harvesting: when sowing in spring, the leaves are harvested already in July, when sowing in summer - next spring. For a season the leaves are cut several times in 2-3 weeks. The highest yield is obtained in the second year after sowing. The harvest is started when the leaves reach a length of 10-12 cm.
Usage: Basal rosette leaves are used for food. Of these, green cabbage soup is cooked, pies are stuffed, prepared for winter. As a remedy, sorrel is used for stomach disorders, jaundice and other liver diseases. However, due to the high content of oxalic acid, it can not be used in cases of salt metabolism, intestinal inflammation and tuberculosis.
In order to get the greens of the sorrel in the winter, in the third year in the autumn it is selected from the soil of the plant and stored in the basement at a temperature of 0.5-3 ° C.The leaves are removed from them, and in February or March the roots are planted in the greenhouse soil or in boxes at a distance of 5-6 cm. At a temperature of 17-18 ° C, leaves suitable for harvesting develop after 2-3 weeks. In total, 3-4 cuts are carried out in 10-15 days. Regularly give fertilizing with weak solutions of fertilizers, dissolving in 10 liters of water 8-10 grams of ammonium nitrate and 5-6 grams of potassium salt.
