Euphorbiaceae is the seed of Euphorbiaceae. Also known as thousand taels of gold, Bodhisattva beans, continue to follow the son, reject the winter, step by step, reject the winter, beach board rescue, see the garden old, hundred medicine solution, dry gold medicine solution, small Croton. The original plant continues with the son also known as: anti-winter, Scutellaria barbata, dragon grass. It has the effect of detoxification, detoxification and insecticidal.

Herbs annual, 30-90 cm tall. Culms tufted, distally erect, base geniculate, with 3-6 nodes, smooth glabrous. Leaf sheaths mostly shorter than internodes, glabrous; ligule membranous, much torn, ciliate; leaf blade striate-lanceolate, glabrous, often crimped. Inflorescences paniculate, branched long, composed of numerous spike-shaped racemes; spikelets with 3-7 flowers, inserted on one side of rachilla in 2 rows, often purplish; glumes with 1 vein, second glume slightly shorter than first Lemma; Lemma with 3 veins, glabrous or proximally puberulent. Caryopsis oblong. The seedlings are light green; the first leaf is 2-2.5 mm long, elliptic, with obvious veins, and the second leaf is 5-6 mm long; 7-8 leaves appear tillers and stolons and adventitious roots. Distribution: in China, it is mainly distributed in East China, Central China, South China, Southwest and Shaanxi and other places. Born in paddy fields, low-wet dry fields and the edge of the ground. The cultivation techniques are introduced as follows:

1. Soil preparation and fertilization: this variety is not strict on soil quality, including sandy loam, loess, white meal soil and wheat field soil, but sandy soil humus soil is the best. Before soil preparation, according to the degree of fertility of the land, generally apply 50 kg of phosphate fertilizer, 25 kg of urea or 50 kg of compound fertilizer per mu, ploughing and raking fine, and finishing 2 Mel flat beds with a width of 3 meters. Waiting to sow seeds.

Second, sowing: Qianjin is propagated with seeds, which are divided into autumn sowing and spring sowing. Autumn sowing is around October, spring sowing must be early, it is better before and after the spring equinox, and the yield decreases obviously when it is late. The use of direct seeding, according to the line spacing of about 40 cm, open 2 cm deep trench, the seeds will be sown after a light step, such as drought can be watered, if the surface is moist can not be watered. Use 2 to 3 kilograms of seeds per mu.

Third, field management: after the seedlings come out, attention should be paid to ploughing and weeding, watering in dry weather and timely drainage in overcast and rainy weather. Stop watering in the fruit. Qianjin has strong adaptability and there are few diseases and insect pests in the whole growth process.

Fourth, harvest and processing: autumn sowing and ripening in June of the following year; spring sowing and fruit ripening from White Dew to the Autumn Equinox in that year. After maturity, thousands of gold can be harvested by combined harvest. After the harvest of gold will be dried to remove impurities can be used as medicine for sale. The yield per mu is 150 Mu and 200 kg.
