Little red and its cultivation techniques
Little red emilia sonchifolia (l.) dc. , alias Rumex, red back, red under leaves, red back fruit, etc., Asteraceae is a year-round or perennial herb, distributed in South China, Central and Southwest China and other places. A little red and cool, with detoxification, blood circulation effect. Can cure bacillary dysentery, acute enteritis, urinary tract infection, pharyngitis, bruises, sores and so on. A little red picking shoots feeding, boiling water, add garlic, stir fry for soup. The taste is smooth, delicious and delicious. 1, the characteristics of a little red plant height 10--40cm. Roots are shallow, with many lateral roots. Stems erect or nearly erect, bald or sparsely hairy, pinkish green, with many branches. Leaves simple, slightly fleshy, born in lower leaves ovate, meibomate or serrate, 5--10 cm long; upper leaves small, entire, sessile, amplexicaul, leaves grayish green, often with purple leaves red. Flower heads, long-handled, usually 2- or 3-branched, purplish green, cylindrical, purple flowers. Fruits are achenes, narrowly oblong, ribbed, and white crested. Seeds are small, lanceolate, light brown, with vertical stripes on the surface. A little red hi warm and cool, moist environment. They are often sparsely shaded and moist, but they are more tolerant to drought and can grow on dry slopes. 2. Cultivation Techniques 1. Soil fertigation requires little soil, and it is better to plant loose, slightly fertile land. Although it is more tolerant, it is advisable to apply sufficient basal fertilizer, and 667 m2 of decomposed organic fertilizer should be applied to 1500--2000 kg to make a sorghum with a width of 1.5 m (including ditch). 2 Breeding a bit of red generally adopts seed breeding. Since the seeds are small, they can be mixed with fine sand and sown in windless weather. Spring and summer sowing seedlings, seedbeds full of decomposed organic fertilizer (1500-2000kg per 667 square meters) as the base fertilizer, pay attention to more water during the nursery, to keep the seedbed moist, covering the shade net is conducive to moisture. Seedling growth conditions appropriate top dressing. When the seedlings have a 3--5 leaf colonization. 3 The colonization of the planting and colonization was 15-20cmx20cm, and the rooting water was sprayed. Live seedlings were divided into 2 to 3 sub-seedlings, and the spacing of the seedlings was the same as that of planting. 4 During the growth period of field management, topdressing is appropriate. Fertilizer should be applied to decomposed organic fertilizers. At the same time, attention should be paid to the enhancement of water-spraying to keep the field moist and increase the yield and quality. Every time harvest 1 fertilizer, urea 5-10kg per 667 square meters, water application, promote new shoots, increase production. 5 When harvesting plants 5--6 leaves, shoots can be picked as young shoots, leaving base axillary buds when picking, and new shoots with 4--5 leaves can be picked. Timely harvesting can increase production, over harvest, increase fiber, and reduce quality. In Guangdong, it can grow throughout the year and continuously picking and selling the young shoots. 667 square meters produces 1500--2500kg.
