The latest course of field management techniques of Atractylodes macrocephala Koidz

Atractylodes macrocephala Koidz is one of the bulk medicinal materials planted at home. In recent years, with more and more people planting, its planting efficiency is getting better and better, and it is also a better project in the cultivation of medicinal materials. However, if Atractylodes macrocephala Koidz can achieve high yield and improve income, it is inseparable from its field management. Let's take a look at the field management techniques of Atractylodes macrocephala Koidz with the editor.

1. Ploughing and weeding

In the whole growth period of Atractylodes macrocephala Koidz, 3-4 times of weeding should be carried out. When the seedlings grow to 3-5cm, the first time of weeding should be shallow ploughing to loosen the soil, so as not to harm the root system, but the weeding should be deep, which can promote the root system extension. Later, the weeding should be shallow hoe to avoid root damage. When the plant enters the peak growth period, it is not necessary to carry out intermediate ploughing, but once weeds are found to be pulled out manually, the soil should be loosened in time after rain to improve soil permeability to facilitate plant growth. It should be noted that when the dew is not dry after the rain, it is not suitable to weed, otherwise the plant will be infected with leaf blight.

2. Topdressing

Topdressing also needs to be carried out 3-4 times, which can be combined with ploughing and weeding. In the first topdressing, 1500 kg of rotten human feces and urine per mu is applied to promote seedling growth; the second person is in May, when the plant is in the vegetative growth period, about 2000 kg of rotten human feces and urine or 10 kg of ammonium sulfate are applied per mu. The third time in the bud picking period, when the underground rhizome began to expand and absorb fertility, 2000 kg of rotten human feces and urine, 100kg of mature cake fertilizer and 50kg of phosphorus and potassium compound fertilizer were applied per mu.

3. Irrigation and watering

Atractylodes macrocephala Koidz is afraid of waterlogging, if the humidity in the field is high, it is easy to cause diseases, so we must pay attention to watering, one time should not be watered too much, less watering can be used for many times. Drainage and waterlogging prevention measures should be taken in time after the rainy season, and the furrow should be cleared. In the early and middle stages of growth, the demand for water in Atractylodes macrocephala Koidz is not high. However, in the later stage of growth, when the rhizome begins to expand, its water demand increases sharply, so it is necessary to be prepared for watering to ensure adequate water supply, promote tuber expansion and increase yield.

4. Pick buds and remove tillers

The budding of Atractylodes macrocephala Koidz from May to June is that in order to promote the growth of the rhizome and improve the variety, except for the remaining plants, the rest of the plants should remove all the buds before budding and flowering. The time of bud picking is also very important, not too early or too late, early plant tender, affecting plant growth, too late will consume too much nutrients, the most suitable time is when the floret spreads and the bread outside the bud is slightly yellow. When picking buds, hold the stem with one hand and pick buds with the other, keep the leaflets, fertilize and maintain nutrients in time after picking buds, it is best to choose sunny days to avoid dew and Rain Water soaking into the wound in the morning and rainy days, causing disease and decay. In the same plant from August to September, tillers will grow on the rhizome, which should be removed in time so as not to consume too much nutrients and affect the yield.
