The latest course of planting techniques and methods of three-leaf green

Three-leaf green is a herbaceous vine of the grape family, also known as three-leaf cliff climbing vine, snake aconite, stone mouse, etc., the whole grass can be used as medicine, raw hillside thickets, valleys, streams under the forest rock cracks, the medicinal effect of underground roots and fruits is the best, due to different producing areas, its shape and medicinal properties will be slightly different, let's take a look at the planting technology of three-leaf green!

Growth habit

Sanyeqing prefers cool climate, and its growth is robust at about 25 ℃, and stagnates when the temperature drops to 10 ℃ in winter. Resist drought and avoid stagnant water. The requirement of soil is not strict, it is better to plant on soil rich in humus or calcareous. Strong negative resistance, disease resistance, less insect pests, very cold-resistant, strong plasticity, wet outdoor environment can be laid and planted, the survival rate, coverage rate is very high, the growth rate is fast.

Breeding technology

Trifolium trifoliate is usually propagated by cuttage, which is better in spring and summer. Select the sturdy branches, cut the cuttings of 12cm to 15cm, insert them into the seedbed obliquely, and bury them at the depth of 2 to 3 of the technical strip. press them after insertion and water them to moisturize. About 30-40 days after insertion, it can be planted when it grows roots and leaves. The holes were opened according to the row spacing of 100 × 100 cm, and 3 plants were planted in each hole, pressed and poured with fixed root water. In addition, seeds can also be used to reproduce.

Field management

When the trifoliate vine grows to 35cm to 40cm, it sets up a frame to draw the vine to climb. Three or four times a year, human feces, urine or chemical fertilizer were applied in spring and summer, compost or stable manure was applied in ring-shaped ditches in autumn and winter, and soil cultivation was carried out. Cut off dense and weak branches and dead branches properly in winter. Leaf spot disease is the main pest control of three-leaf green leaves, which can be controlled by 65% zinc 55-fold solution or Bordeaux solution with 1-1-150.

Timely harvest

The medicinal value of trifoliate green does not lie in its size, which is similar to that of other valuable traditional Chinese medicines, but in the number of years of growth and the selection of appropriate mining time. The Winter Solstice chooses the growing period of more than three years to pick every year during the hibernation period. This picking method has good quality (dormant period) and high quality. At this time, the starch content of the picked root is more than 70%, and the medicinal effect is the best.
