Amino acids contain 10 essential amino acids for children. Scientists have conducted in-depth research on nearly 100 kinds of chemical constituents of Perilla frutescens, indicating that linolenic acid in Perilla seed is an essential factor for maintaining the functions of the brain's nervous system, and has antithrombotic, blood pressure-lowering, weight-reducing, and hypolipidemic effects. Prevent canceration and inhibit tumor metastasis, improve learning and memory, visual function, and change allergies. [Plant form] Annual herb, 60-90cm high, white villous on upper part. Leaves opposite, leaves ovoid or rounded, 3–9.5 cm long, 2–8 cm wide, apex acuminate or caudal, base suborbicular, margin serrate, both surfaces purple, pale red, glandular point. Umbrella inflorescences 2-flowered, compose peduncles that are biased to one side; bracts ovate, apically acute or caudate; calyx campanulate, outside pilose and glandular; corolla purplish red or pale red, corolla tube Ring hair inside, 2 lip shape, slightly concave upper lip, lower lip 3 crack; stamens 4. Nutlets are subglobose, yellow-brown, with a reticular pattern. Flowering from July to August, fruiting period from September to October. Perilla is the dried aerial part of the labiata plant perilla. Also known as Chisu, Red Su, Hong Su. The whole grass is the name of the whole Soviet Union, with a cold solution table, the function of qi and wide chest. The fruits, leaves and stems of perilla are called Suzi, Suye, and Su, respectively, and are used for medicinal purposes. Suzi has the function of moistening the lungs, lowering the air, and eliminating phlegm; the Suye and Su fangs have the same efficacy as the entire Soviet Union, but the Su fangs still have the effect of tocolysis. Perilla can be used as a medicine, and the raw product is also a condiment on the table. From late March to mid-April, when the seeds are sowed, the seeds are mixed with fine sand and evenly scattered into the hole to cover the thin soil and a little repression. The seedlings can emerge 5-7 days after sowing. Drainage and irrigation: more water is needed for seedlings and flowering, and watering should be done in time of drought. Pay attention to drainage during the rainy season. Pest control spot blotch: Originated in June and damaged the leaves. Control methods: At the beginning of the disease, spray 70% dry powder of powdered zinc dextrin suspension; or use 1:1 200 times Bordeaux spray to control. Harvesting and processing The harvesting period varies depending on the use. Generally 1.5-3 cm from the spike, the plant contains most of the volatile oil. Therefore, the whole plant is harvested for the whole Soviet Union at the beginning of the inflorescence in August-September. When the foliage is luxuriant, the leaves are dried and the leaves are dried. When the fruit matures, the whole plant cuts off and is dried, and the fruit is Suzi; the lower branch of the stem is removed and the side branch is the Su stem. The seed retention technology should be reserved for sparse planting, with a spacing of 50 cm and 80 cm. Plant strains should be selected strong, high yield, both sides of the leaves are purple plants, until the seeds are fully mature gray brown when harvesting threshing, drying, miscellaneous, dry and cool place.
